Congratulations on your
purchase of the Maretron MPower® CLMD16, 16 Channel
DC Load Controller Module. Carling Technologies has designed and built your
CLMD16 to the highest standards for years of dependable and accurate service.
The Maretron CLMD16 contains
16 output channels implemented by direct current (DC) Electronic Circuit
Breakers (ECB’s). Twelve breakers can switch up to 12 Amps, and four breakers can
switch up 25 Amps, with a total current capacity of 125 Amps. In addition to
fast switching, low-loss solid state ON/OFF switches, it provides accurate
current measurement for each load as well as short circuit protection. Certain
breakers can be configured to operate in full-bridge mode, making them ideal
for control of electric motors where a reversing polarity function is needed.
The
CLMD16 additionally contains 8 input channels configurable to sense whether the
input is connected to DC (+), DC (-), or connected to neither. The CLMD16 also
contains two resistive input channels (250Ω and 1KΩ) and a single 4-20mA
current loop input channel which could be used for indication of tank levels. The
CLMD16 supplies a set of output terminals which can be connected to an external
alarm LED, sounder or relay which can be activated under a wide variety of
conditions. Additionally, the CLMD16 contains 4 input channels separate from
other inputs reserved for digital addressing or future expansion of input
capability.
The CLMD16 connects directly to one
or two NMEA 2000® networks so you can control the breakers from any device
running Maretron N2KView® software, such as TSM-Series multifunction displays
or MBB-Series black box. Breakers may also be controlled directly from a VMM
Switch or CKM keypad, or any other device transmitting the NMEA Binary Status
Report PGN (127501) Additionally, since the CLMD16 supports standard NMEA 2000® messages
for control, it can be controlled by many third-party multi-function displays.
The CLMD16 handles resistive
DC loads like lights or inductive DC loads like pumps and motors as well as
capacitive loads. An added benefit of the CLMD16 is that it reports the current
through each of the 16 breakers. This allows you to determine if loads are
drawing too little electrical current, or if the loads are starting to draw too
much electrical current.
The Maretron CLMD16 is designed to operate within the
harsh demands of the marine environment. However, no piece of marine electronic
equipment can function properly unless installed, configured, and maintained in
the correct manner. Please read carefully and follow these instructions for
installation, configuration, and usage of the Maretron CLMD16 to ensure optimal
performance.

The CLMD16 provides the ability to control DC power to a
load circuit using 16 independent solid-state PWM capable Electronic Circuit
Breakers (ECBs). Each breaker contains protection against overcurrent,
over-temperature, and short circuit. Traditionally, a bank of mechanical
circuit breakers is located on a panel from where bundles of cables lead to the
various loads located throughout the vessel. As the circuit breaker panel may
be some distance from the load, extensive wiring is required. By placing a
CLMD16 close to the loads being serviced, wiring becomes reduced. The CLMD16 is
simply connected to a suitable local power supply and the vessel’s NMEA 2000® network. The
output breakers on the CLMD16 are then connected to the loads that they
control, often by cables considerably shorter than those required on vessels
with conventional circuit breakers. Several CLMD16’s may be placed in different
parts of the vessel, all controlled electronically via one of the interfacing
methods described below. An added advantage is that as requirements change,
circuits can be reconfigured without making any physical changes to circuit
breakers as would be required with traditional mechanical circuit breakers.
Each breaker output in the CLMD16 may be controlled using
any of the following methods:
1)
Maretron N2KView® software running on a personal computer*
2)
Maretron N2KView® software running on a Maretron MBB-Series Black Box
for Vessel Monitoring and Control
3)
Maretron N2KView® software running on a Maretron TSM-Series Vessel
Monitoring and Control Touchscreen Computer
4)
Maretron N2KView® Mobile app running on an Android or iOS tablet or phone**
5)
Maretron DSM-Series NMEA 2000® Multi-function Color Graphic Display
6)
any NMEA 2000®-connected switch, such as an Maretron MPower® CKM-Series network-connected keypad or VMM-Series network-connected switches
7)
any NMEA 2000® product that can transmit standard NMEA 2000® control messages such as a third-party MFD (please
refer to Appendix A for details).
8)
Any of the 8 hardwired inputs on
this CLMD16, another CLMD16 or a CLMD12.
* Requires a USB100 or IPG100 gateway with a License Key
** Requires an IPG100 gateway
The breakers can be controlled and monitored through use
of the Breaker/ Switch component in the Electrical Distribution category of the
Maretron display products listed above. In addition, the current through each
breaker may be monitored through the Breaker/ Switch Current component in the
Electrical Distribution category of Maretron display products.
Since the output channels are implemented by electronic
circuit breakers, if the unit’s Main DC(+) is removed, all breakers will revert
to the open (OFF) state. The state that the breaker will be in when the unit’s
Main DC(+) is restored can be configured to be ON, OFF, or in the last state
the breaker was in before Main DC(+) was removed. If NMEA 2000® power is lost,
the breakers will maintain their state and can be manually operated through the
capacitive touch local override control panel located on the front of the unit.
To place the unit into “Override Mode”, the “Override key must be held for 1s.

Warranty Registration Card
If
any of these items are missing or damaged, please contact Maretron Technical
Support
(please
refer to the Technical Support section
for contact information).
Please
consider the following when choosing a mounting location.
- The CLMD16 is waterproof, so it can be mounted in
a damp or dry location.
- The CLMD16 is temperature-rated to 70°C (158°F),
so it should be mounted away from engines or engine rooms where the
operating temperature exceeds the specified limit.
- Mount the unit vertically with the connectors
coming from the side or horizontally with the connectors coming from the
bottom of the unit.
Locate and drill mounting holes according to the
mounting template supplied with the CLMD16. Attach the CLMD16 securely using
mounting screws or other fasteners through the four mounting holes at each
corner of the unit. Do not use thread-locking compounds containing methacrylate
ester, such as Loctite Red (271), as they will cause stress cracking of the
plastic enclosure.
Connecting the CLMD16 consists of making the following six
connections outlined below:
·
Connecting the unit’s (2) main DC connections
·
Connecting output and input connections (J1-J3)
·
Connecting to the vessel’s NMEA 2000® network
Required
connections for the CLMD16 are shown in Figure
3
Figure 3 - Required Connections
The unit’s main DC (+) connection is made using commonly
available components not included with the CLMD16.
Connect a source of DC (+) with a ring terminal to the
5/16”-18 stud on the front of the device and torque the connection within the
specified range of 30 – 35 in-lbs. (3.39 – 3.95N·m). Ensure that the cable
providing the Main DC (+) source is protected by a fuse or circuit breaker with
a value appropriate to protecting the wire. Cable runs should be kept as short
as possible to avoid unnecessary voltage drop. If unsure of appropriate cable
sizing, the CLMD16 load calculation requirement can be found by using a load
calculation reference table as outlined by ABYC 11.8.1. See Table 1 for an example of
this load calculation method. Using the load table's findings, choose an
appropriate feeder cable per ABYC E-11, Table 9 and 10. If unsure, consult a
certified regulatory standard installer for your application type.
Note: Multiple CLMD16 units can be
connected to the same Main DC (+) feeder source so long as the unit’s main fuse
/ breaker overcurrent protection does not exceed 125A (The maximum
specification of the CLMD16) and the feeder wire to each unit is sized identically.
Table
1 - Main DC (+) Load
Calculation Table Example
The unit’s main DC (-) connection is made using commonly
available components and are not included with the CLMD16.
Connect the Main DC (-) connection with a ring terminal to
the #10 stud on the front of the device and torque the connection within the
specified value of 10 – 15 in-lbs. (1.13 – 1.69 N·m). Because the Main DC (-)
connection has the potential to be a current carrying conductor, a 10 AWG
minimum wire size is mandatory for this connection. Failure to adhere to this
recommendation may void unit’s warranty. It is recommended to increase the size
of this connection if the length of the wire exceeds (20) Ft or (6.0) M. from
the vessel / vehicle’s main ground source. If unsure of appropriate cable
sizing, use Table
2.

The J1-J3 receptacles on the CLMD16 unit were designed to
accept Deutsch brand DTP, DT, and
DRC series plugs. Maretron supplies optional premade 2m
harnesses for the J1 and J2 connections and a 2m wiring kit for the J3 connection.
Alternatively, the installer may choose to wire the plugs directly.
Wiring a Harness Directly to J1-J3
If connecting harnessing directly to the J1-J3
receptacles, a Deutsch HDT- 48-00 crimp tool will be needed and possibly the
Deutsch DTT-12-01 crimp tool (for 10 AWG Wire connections) (see: Figure 4). A description of the Deutsch brand components that will be needed for connecting
to the J1-J3 connections are outlined in
Table 3.

Once all the connections to the CLMD16 have been
completed, check to see that
information is being properly transmitted by observing an
appropriate NMEA 2000® display. If
you do not see channel on/off status, refer to Section: Troubleshooting.
The NMEA 2000 connectors are round five-pin male
connectors and can be found on the bottom of the CLMD16 enclosure labeled ‘J4 /
CAN-A’ and ‘J5 / CAN-B’. See these connectors in Figure 4. These connectors are
known as DeviceNet or NMEA2000 micro-C connectors. Connect the CLMD16 to a NMEA
2000 network using a Maretron NMEA 2000 cable (or compatible cable) by
connecting the female end of the cable to the one of the male NMEA 2000
connectors on the CLMD16 (note the key on the male connector and keyway on the
female connector). Be sure the cable is connected securely and that the collar
on the cable connector is tightened firmly. Connect the other end of the cable
(male) to the NMEA 2000 network in the same manner. The CLMD16 is designed such
that you can plug or unplug it from an NMEA 2000 network while the power to the
network is connected or disconnected. Please follow recommended practices for
installing NMEA 2000 network products.
NOTE: It is only necessary to connect one of the NMEA 2000
connectors to a network. Two connections are included for use where two
parallel networks are run side by side. If only one network is used it is
recommended to cap the secondary unused network connector.
NMEA 2000 connections can be made using pre-assembled
leads or may be made using field attachable connectors and cables (See: Figure 7).
Figure
7 - NMEA 2000 Connectors
Please refer the Maretron website (www.maretron.com/products/cabling.php
) for relevant products.
Soft Start is a function that ramps up the voltage, of an breaker
output when it is turned on to reduce the inrush current to the device being
powered. (See: Figure
8)
Figure
8 - Soft Start Voltage Ramp
Soft Start ramps the voltage of the breaker output, over a
1 second period. This is to overcome initial inertia in large systems at
start-up.
Soft Start has a configurable initial voltage expressed as
a percentage of the full voltage. The Soft Start Initial Duty Cycle defaults to
20%.
Some breakers can be operated in pulse width modulation
(PWM) mode, also referred to as dimming, to control the brightness of
incandescent or LED lighting. The breaker may be configured to any value
between 5% to 100% in increments of 1%.
Please note that the dimming function is not supported on
breakers that have been configured to operate in parallel with other breakers.
Some CLMD16 breakers can be configured to operate in parallel
for higher current capacity:
Breakers #1 and #2
Breakers #3 and
#4
Breakers #7 and #8
Breakers #13 and #14
• When connecting paralleled breakers to a load, both
cable lengths connected to the load must be equal. Rather than running twin
cables, it is often easier to connect the two outputs together at a terminal
block by using a jumper, and then running a suitably sized single cable to the
load. This ensures a matched impedance. (see: Figure 9)
Figure
9 - Paralleled Breakers Connection Recommendation
Please note that the maximum current rating when
multiple breakers are paralleled is typically, 180% of the single channel
rating. (Example: 18A maximum for two 10A breakers in parallel).
When
two breakers are configured in parallel, the
lowest-numbered breaker controls the pair For example, if breakers #1 and
#2 are configured to operate in parallel, commands that control breaker #1 will
control the state of both paralleled breakers. The lowest-numbered breaker will
also set the trip current for both breakers. The trip current will need to be
configured to 50% of the desired trip current value. For example, if you
parallel breaker #1 and breaker #2 and wish to use them to supply power to a
load rated around 12 Amps, breaker #1 will need to be set to 6 Amps. Lastly, dimming
operation is not supported on breakers that have been configured to operate in parallel with other breakers.
12-amp breakers 1 and 2, and 11 and
12, can be configured to offer polarity reversing capability by configuring the
breaker type to ‘Full-Bridge’ (H-Bridge). Loads such as actuators are a great
application for this circuit type. The full bridge breakers support PWM
operation with a duty cycle of 10% to 90%, programmable in 1% increments. The
PWM frequency in continuous mode is 20 kHz. See: Figure 10 for Full-Bridge concept pertaining
to CLMD16.
Note: Breakers 1,2 and 11,12 utilize Half-Bridge circuit topology. These
breakers, when configured to Full-Bridge Mode utilize the two (2) half bridge
circuits to drive Full-Bridge (Polarity Reversing). This makes the breaker
output ‘pull down’ or connect to DC(-) when the breaker is in the off state
rather than become high impedance. This feature passively brakes DC motors by
removing electrical fields that naturally occur when a motor coasts to stop.
Figure
10 - Full Bridge Operation Concept
Load shedding is a way to extend the time the system can
keep working when the battery voltage is getting low. As the battery voltage
drops, the CLMD16 will turn off low priority loads. This is based on 3 priority
levels. These priority levels have configurable voltage thresholds. An example
of this is depicted in the table below. As voltage rises, for instance, as
batteries are recharged, loads will be reactivated in a reverse sequence of the
order in which they were turned off. See Table
7 for an example of Load shedding Priority based on battery voltage.

There are three load shedding levels:
•
Low
•
Medium
•
High (default)
Each channel has a load shedding priority which is user
configurable.
The Medium and Low load shedding priorities have a user-configurable
deactivation threshold and an activation threshold voltage level.
The Load Shedding Medium Priority Deactivation-threshold
voltages must always be lower than the Low Priority Deactivation-threshold.
Load shedding will never turn off (shed) channels assigned
to the High Load Shedding Priority.
The Electronic Circuit Breaker feature is fundamental to
the CLMD16 product; the purpose of the feature is to automatically disconnect a
load from the supply when an electrical fault is detected to protect the load
and its supply wiring from damage.
The CLMD16 Electronic Circuit Breaker trip behavior mimics
the operation of traditional circuit breakers. The time a mechanical circuit
breaker takes to trip is governed by several factors, including sensing time,
unlatching time, mechanical operating time, and arcing time. In the CLMD16,
this is replaced by configurable parameters.
The Electronic Circuit Breaker performs the following
protective functions:
•
Overload Protection (long time delay trip
function)
• Short circuit protection with delayed trip (short time
pickup)
• Instantaneous short circuit protection (instantaneous
trip function)
Each Electronic Circuit Breaker uses a microprocessor to
process the current signal and operate
the circuit breaker opening in case of fault. By digital processing of the
signal, they provide the following
protection functions:
•
Long Time-Delay trip function.
•
Short Time-Delay trip function.
• Instantaneous trip function.
To mimic the function of traditional mechanical circuit
breakers, it is possible to configure the time-delay trip function through the
NMEA 2000® interface
to suit connected loads. The CLMD16 can trip if there is an over-current or
thermal event-based trip characterized by an Instantaneous, Short, or Long time
delay curve. Each of these curves has an instant trip region, as shown in Figure 11.
Figure 11 - Current vs Time Graph
The nominal current that can flow through a breaker is
determined by the power it can dissipate continuously without exceeding its own
thermal limits. When an overcurrent condition is detected, the CLMD16 will
trip, turning off the current to the supplied load. The breaker can be reset by
turning OFF and then ON again through the NMEA 2000® interface or at the capacitive touch
local override control on the front of the unit.
The breakers in the CLMD16 are configurable so that
nuisance tripping is avoided where the start-up current may be more than those
experienced in a continuous duty cycle.
The system installer / configurator will need to know the
current rating of the load, the maximum start-up peak current, and duration
allowed for the peak in order to correctly configure the ECB settings.
The CLMD16 can translate the voltages measured on the
eight voltage sensing hardwired inputs, the resistances monitored on the two resistive
hardwired inputs, and the current monitored on the current loop hardwired input
for use in controlling loads or for use as inputs to the various elements in
the switching application (for example, counters, tank levels, timers, etc.).
This is done by using the input monitor. On the eight
voltage sensing inputs, the input monitor will translate the input voltage
signal from an input to one of three states:
•
LOW (Connected
to DC-)
•
FLOAT (No
Connection)
•
HIGH (Connection
to DC +)
The voltage levels at which these states are calculated
are individually configurable for each of the input channels.
There are eleven input monitors in the CLMD16. Each of the
eight hardwired voltage sensing inputs, the two hardwired resistive inputs, and
the current loop input has an associated input monitor. The monitor operates
the same way for the resistive hardwired inputs and the current loop input as
the voltage sensing inputs only measuring resistance to DC (-) or Current in mA
instead of measuring voltage.
There are two configurable voltage, resistive or current
levels:
•
Low Threshold
•
High Threshold
The input monitor also implements a configurable amount of
hysteresis. This is where the value of a physical property lags behind changes
in the effect causing it, as for instance, when magnetic induction lags behind
the magnetizing force.
Hysteresis causes the input monitor to behave such that
the input states will not quickly transition between states when the input
voltage is near one of the threshold voltages. There is a separate hysteresis
value for each threshold:
•
Low Hysteresis
•
High Hysteresis
Figure 12 shows an example
of how the hysteresis works on the voltage sensing inputs.
Figure
12 - Binary Event Monitor Hysteresis
Each channel of the input monitor produces three signals
that are available to the Switching Application:
Input x Low – the input monitor for channel x is in the LOW state
Input x Float – the input monitor for
channel x is in the FLOAT state
Input x High – the input monitor for
channel x is in the HIGH state
The CLMD16 contains a variety of combinatorial and
sequential logic elements to allow the construction of control applications.
These logic elements can be connected and configured in a wide variety of ways
to create a wide variety of control applications.
The CLMD16 switching application contains sixteen
instances of a counter function.
Each counter may be configured in one of the following
modes:
• Active High – The counter increments or
decrements as long as the increment or
decrement input signal is in a high state
(connected to DC (+))
• Active Low – The counter increments or
decrements as long as the increment or
decrement input signal is in a low state
(connected to DC (-))
• Rising Edge – The counter increments or
decrements once for every rising edge
detected on the increment or decrement input
signal (voltage rising)
• Falling Edge – The counter increments or decrements once for every
falling edge detected on the
increment or decrement input signal
(voltage lowering)
• Change Detected – The
counter increments or decrements once for every rising or falling edge detected
on the increment or decrement input signal
• One Button Smooth Scroll – This mode
is designed to allow one button power and dimming control for lighting circuit.
The counter operates differently in this mode. First, the Decrement
input is ignored. Second, the Counter Active output becomes a
power output for the lighting circuit. Here is how to use this mode: Connect
the button you want to control the light to the Increment input. For
the breaker(s) controlling the lighting, connect the Counter Active
output as the Input Signal, set the breaker mode to “PWM”, and select the
counter you are configuring as the “PWM Counter”. In this mode, a quick press
of the button (less than Hold Period) will cause Counter Active
(and thus the breaker power) to toggle state. Holding the button longer than
this will cause the dimming level to cycle from 5% to 100% and then back from
100% to 5% until you release the button. The dimming level is remembered when
you turn the circuit ON and OFF again by quickly pressing the button.
Each counter has the following input signals:
•
Increment – causes the counter to increase in value*
•
Decrement – causes the counter to decrease in value*
•
Reset – causes the counter to be set to the Min Set Point value
Each counter has the following output signal:
• Counter Active – this is asserted high (ON) when the counter value is
equal to or greater than the value
of the Active Threshold parameter*
Each counter has the following programmable parameters:
• Press Step Size – step size
by which to increment or decrement the counter when the increment or decrement input is pressed
• Min Set Point – the value to which the
counter is set when the Reset input is asserted
high
•
Max Set Point – the
maximum value that the counter can reach
• Active Threshold – if the
counter value is above the value of this parameter, the
Counter Active output of
the counter will be asserted high*
• Held Step Time – (Active
High or Active Low mode) once the increment or decrement counter has been
asserted high for Hold Period time, the counter is incremented or
decremented. If the increment or decrement input signal remains asserted high
for this amount of time afterwards,
the counter will be incremented or decremented
again.
• Hold Period – (Active High or Active Low
mode) time after which the input signal is
considered “held” if it remains active
• Hold Step Size – in Active
High or Active Low mode, this is the value by which to increment or decrement
the counter after the increment or decrement input signal has been asserted
high for Hold Period time, and every Held Step Time thereafter.
If the Rising Edge, Falling Edge, or Change mode, this is the value by which to
increment or decrement the counter
on each detected edge of the increment or decrement input signal.
* Please refer to the description of One Button
Smooth Scroll mode to see how these items are treated differently when
that mode is selected.
In Active High or Active Low mode,
the increment input signal being in its active state is ignored if the
decrement signal was already in its active state, and vice versa.
The signals can be used to perform many different tasks
such as push to hold (Momentary state operation), hold to latch (Toggle state
operation), and multi-push (Sequential state operation) etc.
The output signals from the counter elements are numbered 1
through 16
The CLMD16 provides sixteen instances of a timer function.
The Timer function provides the Switching Application the
ability to postpone the activation of load output channels upon receiving
channel activation commands up to 65,535 seconds for each. This is not to be
confused with the Soft Start function as the Timer function does not contribute
to the load PWM output.
Each timer can be configured to one of the following
modes:
•
ON Delay – When the
input signal is applied, the output is delayed by the delay period
•
OFF Delay – When the
input signal is removed, the output is delayed by the delay period
•
No Delay – the
output signal is a replica of the input signal
Each timer has the following input signals:
•
Input – the signal whose delayed version will be produced on
the output
Each timer has the following output signals:
•
Timer Output – the delayed version of the Input signal
Each timer has the following programmable parameters:
• DelayPeriod – the amount of time by
which to delay the appropriate edges of the
input signal to produce the output signal.
If the timer is configured in ON Delay mode and the input
signal is asserted high for less than the DelayPeriod time before
being asserted low again, the output signal will remain asserted low Conversely,
if the timer is configured in OFF Delay mode and the input signal is asserted
low for less than the DelayPeriod time before being asserted high
again, the output signal will remain asserted high.
The output signals from the timer delay elements are numbered
1 through 16
The CLMD16 provides sixteen
instances of a flash function.
The Flash function provides the Switching Application the
ability to turn an output on and off at set frequencies.
This function can be used to generate unique visual error
codes using a load output channel connected to an LED such as Indication of a network
or power supply low voltage state. Or to flash a mast clearance strobe, Pulse
an intermittent bilge pump, or for use with intermittent ON ventilation
systems.
The Flash function has the
following input signals:
• Input
– the flashing function is
enabled as long as this signal is asserted
(ON)
The
Flash function has the following output signals:
•
Flash Output – while
the input signal is asserted this signal will be enabled allowing for the
configurable parameters to take control of the Flash Output
function.
The Flash function has the
following configurable parameters:
• Flash Cycles – once the Input signal is
detected, the Flash Output signal will cycle
for this number of cycles, or until the Input signal is removed, whichever
occurs first.
• Flash On Period – during
each flash cycle, the Flash Output signal will be On for this amount of time
• Flash Off Period – during
each flash cycle, the Flash Output signal will be Off for this amount of time
The output signals from the flash elements are numbered 1
through 16
The CLMD16 provides sixteen set/reset latches, which, as
an example, may be used for loads which use a push on/push off function.
The Latch function has the following input signals:
• Set Input – This signal will cause
the Latch Output signal to turn On
• Reset Input – This
signal will cause the Latch Output signal to
turn Off
The Latch function has the following output signals:
• Latch Output – On
when Set Input is detected or On, and Off when
the Reset Input is detected or On
The Latch function has no configurable parameters.
The output signals from the latch elements are numbered 1
through 16

The switching application provides sixteen instances of a
toggle.
Each toggle maintains its logic state until the single input signal to the toggle
transitions from a On to Off.
The Toggle function has the following input signals:
• Toggle Input – when this
signal is changed from On to Off (Usually a momentary event), it will cause the
Toggle Output signal to change to
the opposite of its current state; for example, if the Toggle Output signal is On,
then will change to Off, and if the Toggle Output signal is Off, it will change
to On
The Toggle function has no configurable parameters.
The output signals from the toggle elements are numbered 1
through 16.
Where “1” is On and “0” is Off, each state change of the
Toggle Input from Off to On changes the state of the Toggle
Output. (see: Table
9)

The switching application provides forty-eight instances
of three-input logic operations.
The Logic (Combinatorial Logic) function provides the
Switching Application the ability to take up to three signals and logically
combine them using Boolean logic to create a logical signal. The three-input
lookup table allows any binary function of three variables to be realized. The
outputs of the logic functions may be used as inputs to other logic functions
(allowing logic functions of more than three inputs to be realized) or as
inputs to other types of functions.
Each Logic Function has the following input signals:
•
Input A – first
input to the logic function
•
Input B –
second input to the logic function
•
Input C – third
input to the logic function
Each Logic function has the following output signals:
• Logic Output – the
logical output of the of Input A, Input B, and Input C as defined by the lookup table
Each Logic function consists of a three-input lookup
table. There are eight rows in the table, one row for each possible combination
of values of the three inputs. For each of the eight rows, you specify an
output value for the logic function, either 0 or 1. For an example, where “1”
is On and “0” is off, consider the logic function ((A and B) or not C). This
function outputs a 1 value when A=1 and B=1, or when C=0. The lookup table
defining this function appears in Table
10.

Functions of more than three variables may be constructed
by using the output of one logic element as the input to a second logic
element, and so on.
The Logic Output signals are numbered 1 through 48.
The CLMD16 provides a single alarm output circuit to drive
an alarm or relay. There are two terminals: Alarm Power (pin J3-16), and Alarm
Ground (pin J3-22). Both of these pins are switched. They are connected to
power and ground, when an Alarm Input signal is detected, and both become high
impedance when the Alarm Input signal is Off or not detected. The max capacity
of this output is 300mA.
The Alarm function has the following input signals:
Alarm Enable – when the Input signal is
detected, this signal will cause the alarm output circuit to be Connected.
There are many signals that are available to connect as
inputs for the various logic elements in the switching application. The Table
11 is a complete list of the
available signals.

The CLMD16 will transmit data over the NMEA 2000® network as it is shipped from the
factory; however, it may require configuration, depending on the type of
switches monitored and the number of similar products on the NMEA 2000® network. There are several
configurable items within the CLMD16, which are detailed in the remainder of
this section.
The CLMD16 is configured using Maretron N2KAnalyzer® V3 software. The following subsections describe the
configurable parameters in the CLMD16.
The General Tab contains commonly used configuration
items. Detailed descriptions of Binary Status Report messages, (127500, 127501
etc.) where these are mentioned in the text, may be found in
Appendix A – NMEA
2000® Interfacing. See Figure
13 for General Tab detail.
Figure 13 - General Configuration Tab Dialog Box
Label
This text box allows you to assign a text label to the
device. This label is visible in Maretron analysis and supported display
products and allows you to easily identify the particular device.
NMEA 2000® provides
a unique instance number for each breaker box on a vessel. This read- only
field shows the instance number assigned to this device. This instance number
value is reflected in the 127501 Binary Status Report message. The instance
number can be configured by changing the “Device Instance” field on the
“Advanced” tab.
Breaker #(n)
This section contains settings for the specified
electronic circuit breaker. One of these sections is present for each of the
breakers in the unit.
Label
This text box allows you to configure a text label for the
breaker to identify it (for example, “RUNNING LIGHTS” or “HATCH”). For each
breaker, set this to a value which describes the breaker so that you can easily
identify it in display devices.
Manual Mode
This drop-down selection allows you to enable or disable
Manual Mode. By default, devices such as an MFD or N2KView will have direct
access to control all CLMD16 breakers. These devices communicate to the
breakers by NMEA 2000 PGN 127500 or PGN 127501 via 126208 Command Group
Function. When Manual Mode is enabled, commands from devices using NMEA 2000
PGN 127500 or PGN 127501 via 126208 Command Group Function is ignored. The
CLMD16 instead will only allow for Network Inputs 1-16 from the Available
Signals list to be used as inputs within the switching application. Please
refer to section 5.7 / ‘Available Input Signals’ for more information on
‘Network Inputs 1-16’. The Manual Mode feature can be used to funnel commands
from any device using 127500 or 127501 via 126208 PGN into CLMD16 Switching
Application Logic. For example, with Manual Mode On, a breaker’s Network Input
signal received from an MFD may be directed into any CLMD16 Switching
Element(s) then back into the breaker control input allowing for ultimate
configurability such as sequencing, special lighting control, modes, and group
switching commanded by the MFD whereas this function would not be possible
using direct breaker control via NMEA 2000 PGN 127500 or PGN 127501 via 126208
Command Group Function. Manual Mode can also be used to simply ignore direct
breaker commands for breakers that are designated for load sequencing, or
sub-routines controlled elsewhere. Manual Mode also can be used for breakers
needing to be controlled by single designated points rather than NMEA2000
network wide access to command the breaker.
This read-only field indicates the current state of the
breaker. It will contain one of the following values:
•
OFF – the breaker is currently off (not supplying power)
•
ON – the breaker is currently on (supplying power)
• TRIP/ERROR
– the breaker is currently off (not supplying power) due to an overcurrent or error condition
PWM Default
This value will be the value that the PWM% will be when
the breaker is turned On if the Counter switching application is
not selected. Please note if PWM is changed via Network Input the
value of PWM the next time the channel is turned On will be the last state of
PWM and the PWM Default will not be applicable until the next
power cycle.
Default State
This allows you to configure the state of the breaker when
the CLMD16 is powered on. You can set this to one of the following values:
•
OFF – the breaker will be OFF after the
CLMD16 is powered on
•
ON – the breaker will be ON after the
CLMD16 is powered on
• LAST STATE
– after the CLMD16 is powered on, the breaker will be set to the state it was in when power was last removed
Default Lock State
This parameter allows you to configure whether the breaker
is locked when the CLMD16 is powered on. You can set this to one of the
following values:
•
LOCKED – the breaker is locked, i.e., it’s state will not
change due to network inputs
• UNLOCKED
– the breaker is unlocked, and its state will respond normally to network inputs
Type
This parameter allows you to configure the desired
operating mode for this breaker. You can choose one of the following:
•
DC – the breaker may be controlled OFF and ON.
• PWM –
this breaker may be controlled OFF and ON and may be dimmed by altering the changing duty cycle of the PWM
counter assigned to the breaker.
• Soft Start DC – the breaker may be controlled OFF and ON. When the breaker is turned ON, the power starts in PWM mode
with the duty cycle set by “Soft Start %” parameter, and then ramps to fully ON
over the next one second time interval.
• Full-Bridge
– if both breakers in a full-bridge pair (i.e., 1 and 2, or 11 and 12) are
configured to Full-bridge, then the two breakers will work together as a full
bridge
( H- bridge). The full bridge may be
controlled OFF and ON, and its direction may be controlled.
• Soft Start Full-Bridge – if both breakers in a full-bridge pair (i.e., 1 and
2, or 11 and 12) are configured to Soft Start Full-bridge, then the two
breakers will work together as a full-bridge (H-bridge) with the soft start
feature enabled. The full bridge may be controlled OFF and ON, and its
direction may be controlled. When the breaker is turned ON, the power starts in
PWM mode with the duty cycle set by Soft State % parameter,
and then ramps to full ON over the next one second time interval.
Current Rating
This parameter allows you to configure the desired trip
level for this breaker. Exceeding this current for a time period set by the
value of the Long Time Delay parameter along with the i2t breaker model will initiate a
trip.
Instantaneous Pickup
This parameter allows you to configure the Instantaneous
Pickup for the breaker. This can be set in the range of 5
to 20 with a resolution of 1. This parameter is a multiplier of the current
rating. For example, if the current rating for the breaker is set to 6 A and
the Instantaneous Pickup parameter is set to a
value of 10, then the Instantaneous Pickup current
will be 60 A (6 A * 10).
Short Time Pickup
This parameter allows you to configure the Short Time
Pickup for the breaker. This can be set in the range of
1.5 to 6.0 with a resolution of 0.1. This parameter is a multiplier of the
current rating. For example, if the current rating for the breaker is set to 6
A and the Short Time Pickup parameter is set to a
value of 4, then the short time pickup current will be 24 A (6 A * 4).
Input Signal
This parameter allows you to select the internal signal
that determines the state of this breaker. You may choose a signal from the
list in Table 11 - Available Signal Table
Toggle Mode
This parameter allows you to select Toggle Mode On or
Off. When this mode is enabled, the state
of the ECB will change to the opposite state, whether On or Off, with every Rising
Edge of an ECB Input Signal.
PWM Counter
This parameter allows you to select which PWM Counter
controls the dimming level for this breaker. You may choose any of the sixteen Counter
elements. You may also choose No Counter, which allows you to directly
control the dimming level for this breaker from the network.
Long Time Delay
This parameter allows you to configure the long-time delay
for the breaker. This can be set to one of the following values:
•
FAST (5 seconds)
•
MEDIUM (10 seconds)
•
SLOW (20 seconds)
Voltage
This
read-only field shows the real-time voltage at the load terminal of the
breaker.
Current
This read-only field shows the real-time current passing
through the breaker.
Status
This group of indicators show real-time status of the
breaker.
Tripped
When lit, this read-only field shows that the breaker is
in the TRIP state.
Instant Trip
When lit, this read-only field indicates that the breaker
has tripped due to the instant trip feature.
Short Time Trip
When lit, this read-only field indicates that the breaker
has tripped due to the short time trip feature.
Long Time Trip
When lit, this read-only field indicates that the breaker
has tripped due to the long time trip feature.
Thermal Protection
When lit, this read-only field indicates that the breaker
has been turned off due to the thermal protection feature.
Load Shed
When lit, this read-only field indicates that the breaker
has been turned off due to the load shedding feature.
Hardware Fault
When lit, this read-only field indicates that the breaker
has been turned off due to a hardware fault being detected.
Short To Ground
When lit, this read-only field indicates that the breaker
has been turned off due to it being detected shorted to ground.
Short To Battery
When lit, this read-only field indicates that the breaker
has been turned off due to it being detected shorted to the DC supply voltage.
Over Current
When lit, this read-only field indicates that the breaker
has tripped due to an overload being detected.
Open Circuit
When lit, this read-only field indicates an Open Circuit
(no load) condition. The breaker is turned ON but there is little, or no
current being drawn. There are several possible reasons:
•
External switch controlling load
is in the OFF position
•
If the connected load is a light,
the bulb could be defective
•
The load is incorrectly wired
•
The load is very small (less than
1.0 Amps)
Breaker Locked
When lit, this read-only field indicates that the breaker
has been locked and will not respond to switch commands on the network. The
purpose of the lock feature is to avoid inadvertent or accidental breaker state
changes. The breaker must be unlocked before the breaker state can be remotely
changed again.
The
Control tab allows you to toggle the configured Network Input channels
of the CLMD16. Each
On / Off control
number corresponds with Network Input numbers
1-16. When a Network Input is turned on in this dialog, the
associated circuit that the Network Input is configured to
control will be controlled. See Figure
14 for Control Tab detail.

the counter. Each counter may be configured in one of the following modes:
• Active High – The counter increments or
decrements as long as the increment or
decrement input signal is in a high state
(Connected to DC (+))
• Active Low – The counter increments or
decrements as long as the increment or
decrement input signal is in a low state
(Connected to DC (-))
• Rising Edge – The counter increments or
decrements once for every rising edge
detected on the increment or decrement input
signal
• Falling Edge – The counter increments or
decrements once for every falling edge
detected on the increment or decrement input
signal
• Change
– The counter increments or
decrements once for every rising or falling
edge detected on the increment or decrement input signal
• One Button Smooth Scroll – The Increment
Signal input controls One Button Smooth Scroll, The Decrement
Signal input is ignored in the One Button Smooth Scroll Counter
Type selection.
Function:
An
input signal shorter than Hold Period will turn the assigned
breaker’s load on to last PWM state, with the next input signal shorter than Hold
Period the breaker’s load will turn off.
An
input signal longer than the Hold Period time will temporarily disable the decrement function and increment
the counter and will continue to increment the counter on the next input
signal detected longer than Hold Period time until Maximum
Set Point is reached.
Once
Maximum Set Point is reached, an input signal longer than the Hold
Period time will temporarily disable the increment function and
decrement the counter and will continue to decrement the counter on the next
input signal detected longer than Hold Period time until Minimum
Set Point is reached.
(Once
Maximum or Minimum Set Point in the counter cycle is reached the
system will toggle from ascending (increment) PWM to descending (decrement) PWM
or vise versa. For definition of Hold Period see “Hold Period”
on following page.
This parameter allows you to configure the minimum value
that the counter can reach. This is also the value to which the counter is set
when the Reset input is asserted high
Max Set Point
This parameter allows you to configure the maximum value
that the counter can reach.
Press Step Size
This parameter allows you to configure the step size by
which to increment or decrement the counter when the increment or decrement
input is pressed.
Hold Step Size
This parameter allows you to configure in Active High or
Active Low mode, the value by which to increment or decrement the counter after
the increment or decrement input signal has been asserted high (On) for Hold
Period time, and every Held Step Time
thereafter. In the Rising Edge, Falling Edge, or Change mode, this is the value
by which to increment or decrement the counter on each detected edge of the
increment or decrement input signal.

Input # (n)
Label
This box allows you to configure a text label to identify
the input signal, (for example, “HIGH WATER ALARM” or “BILGE BLOWERS”). It is
suggested that a descriptive name is chosen so that you can easily identify it on
display devices.
On Level(s)
This field allows you to select the input signal level that
causes the corresponding field in the 127501 Binary Status Report message to be
set to ON. You may select from one of the following values:
• LOW
When
the digital input is set to active low the corresponding field in the 127501 Binary Status Report message
will be set to ON when the input signal level is less than the Low Threshold.
• HIGH
When
the digital input is set to active low the corresponding field in the 127501 Binary Status Report
message will be set to On when the input signal level is greater than the High
Threshold.
Analog Reference
This field allows you to
select the reference voltage for the input. You may select from one of the
following values:
·
5 VDC – select this option if the
input signal will be limited to voltages between 0 – 5 VDC. This will allow
higher resolution measurements over this limited voltage range.
·
Supply – select this option
if the input signal will have voltages ranging from 0 VDC to the supply
voltage. This will allow the signal to be measured over the entire voltage
range at the expense of lower resolution.
State
This read-only field reflects the current state of the
corresponding binary input signal. This field will take one of the following
three values:
•
LOW – the input
signal voltage is between 0 V and the set Low
Threshold
•
FLOAT – the input
signal voltage is between the set Low and the High Thresholds
•
HIGH – the input
signal voltage is between the High Threshold and the Supply Voltage
Voltage/Resistance/Current
This read-only field reflects the present measured voltage
(for channels 1-8), resistance (for channels 9-10), or current (channel 11).
High Threshold
This numeric field allows you to program a voltage, resistance,
or current value such that when the
detected value on the input signal transitions from below this value to above
this value, the state of the signal shall change from FLOAT to HIGH.
High Hysteresis
This numeric field allows you to program a hysteresis
voltage, resistance, or current value such that when the detected value on the
corresponding input signal transitions from above the High Threshold minus this value, the state of the output
signal shall change from HIGH to FLOAT.
Low Threshold
This numeric field allows you to program a voltage,
resistance, or current value such that when
the detected value on the input signal transitions from below this value to
above this value, the state of the signal shall change from LOW to FLOAT.
Low Hysteresis
This numeric field allows you to program a hysteresis
voltage, resistance, or current value such that when the detected voltage on
the corresponding input signal transitions from above the Low Threshold plus
this value, the state of the output signal shall change from FLOAT to
LOW.
This Tanks Tab contains parameters for configuring tank
measurement via the two resistive channels
and the current loop channel. See Figure 23 for Tanks Tab detail.
Figure
23 - Tanks Configuration Tab Dialog Box
Enable
Each resistive/current loop measurement tool can be
enabled or disabled. If this box is checked, the tank level corresponding to
this channel will be shown. If this box is unchecked, no tank level will be
shown. As shipped from the factory, tank level channels are disabled.
The following sections describe in detail the configuration
of the current loop measurement channel when it is enabled.
Label
Type a description of the tank being monitored in the
field marked Label. Maretron display products will display this label text when
you are selecting data to display. If the channel is disabled, no further
configuration is required.
Pressure
Pressure at 4mA (Current Loop channel only)
Program this parameter to match the pressure reading of
the current loop pressure transducer when it is sourcing a current of 4mA. You can determine this value by examining the
specification of the pressure transducer being used.
Pressure at 20mA (Current Loop channel only)
Program this parameter to match the pressure reading of
the current loop pressure transducer when it is sourcing a current of 20mA. You can determine this value by examining the
specification of the pressure transducer being used.
Tank Capacity
In addition to indicating the fluid level within a tank,
the channel also can be configured or programmed with the attached tank’s
capacity. This way, you will be able to view the tank’s capacity as well as the
amount of liquid remaining anywhere on the vessel where there is an NMEA 2000® compatible display.
Tank Number
Use this parameter to set the tank number for the tank
level channel being configured.
The channel supports up to sixteen potential tank numbers
(0 through 15) for a given type of tank.
Tank Type
This parameter allows you to set the fluid type in the
tank for identification by display devices. You can configure the channel for
any of these tank types:
•
Fuel
•
Fresh Water
•
Waste Water
•
Live Well
•
Oil
•
Black Water
•
Reserved-1 through Reserved-7 (if
none of the above types apply)
Data Damping Period
You can configure a damping parameter to smooth the tank level
or pressure/vacuum readings or make them more responsive. The data damping is
configurable between 0.2 – 25.0 seconds. The default data damping for a channel
is 15.0 seconds.
Realtime Resistance
(Resistive Channels Only)
This read-only field shows the resistance currently being
measured on the applicable resistive input signal.
Realtime Current
(Current Loop Channel Only)
This read-only field shows the current being measured on
the current loop input signal.
Pressing this button opens the Tank Calibration dialog,
shown in Figure
23.
There are two methods of calibration: Manual Table and
Step Fill Table
Manual Table
Using the manual table method, you enter each entry of the
measured parameter (depth) and the level of fluid in the tank. The table may
have as few as 2 entries (for a tank with rectangular cross-section) or as many
as 16 entries (for a tank with a complex cross-section).
Figure 24
- Current Loop Manual Table Calibration Tank, Initial Window Dialog Box
Fluid Density
To convert the pressure measured the channel must know the
density of the fluid being measured. This control allows you to program the
channel with the proper fluid density. You may choose from Diesel Fuel 20,
Diesel Fuel 60, Fresh Water, or you may enter a different numeric density value
appropriate to the fluid whose depth is being measured.
Number of Table Entries
You may choose the number of entries to be in the
calibration table. Two is sufficient for a tank with a rectangular
cross-section. The channel supports up to 16 table entries for supporting tanks
with more complex cross-sections.
Current Tank Calibration
This grid shows the values of the tank calibration table.
Each line of the grid has two entries:
1)
Tank Depth – this is the height of
the fluid above the pressure sensor port
2)
Level (%) – this is the percent
full the tank is at the specific tank depth
Step Fill Table
In the Step Fill Table method, you start with an empty
tank, and then fill the tank with fluid, stopping at intermediate points to
enter the amount of fluid put into the tank thus far, ending once the tank is
full. You may enter between two and sixteen calibration points. (see: Figure 25, Figure 26 & Figure 27),
Figure
25 - Current Loop Step Fill Calibration Tank, Initial Window Dialog Box
To use this method, use the following steps:
1)
Enter the estimated total capacity
of the tank into the “Total Capacity” text box.
2)
Press the “Start Calibration”
button. You will now see the Step Fill Calibration
window displayed, as shown below.
Figure
26 - Current Loop Step Fill Tank Calibration Dialog Box
3)
Enter “0” into the Current Level
text box, and press “Step”. You have now entered
the first point of the table.
4)
Partially fill the tank. Enter the
amount of fluid pumped into the tank into the
“Current Level” text box, and press “Step” (if you make a mistake
entering a level, you can press “Back” and re-enter the level. If you want to
cancel the process, press the “Abort” button).
5)
Repeat the previous step until the
tank is filled.
Once you have entered the last point, where the tank is
100% full, press “Complete”. This will cause the table to be stored in the
device.

The CLMD16 has four LED indicators to show system status.
This LED is used to indicate the state of operation of the
touch controls. It can be in one of the following states:
• Dark: this indicates normal operation
• Flashing red: this indicates a failure requiring service
This LED indicates the state of the NMEA 2000 network
connected to the connector labelled “J4 / CAN-A”. It can be in one of the
following states:
• Flashing blue: this indicates normal operation
• Dark: this indicates no communication is taking place
• Steady Blue: this indicates a fault on the NMEA 2000 network
This LED indicates the state of the NMEA 2000 network
connected to the connector labelled “J5 / CAN-B”. It can be in one of the
following states
• Flashing blue: this indicates normal operation
• Dark: this indicates no communication is taking place
• Steady blue: this indicates a fault on the NMEA 2000 network
This Bicolor LED indicates the condition of the power
being supplied to the CLMD16
• Steady green: this indicates normal operation
• Flashing green: this indicates that the unit’s 125A
total current limit has been exceeded
•
Steady red: this indicates that
the power and ground connections to the unit have been connected with reverse polarity
Each breaker in the CLMD16 has a green LED indicator that
is located on the correspondingly numbered switch on the touch panel. This LED
can be in one of the following states:
• Dark: the breaker is turned OFF
• Steady green: the breaker is turned ON
•
Flashing green: the breaker has
been commanded to turn ON, but is turned OFF due to an overcurrent or short circuit condition
The CLMD16 includes a touch panel made up of capacitive
touch switches to allow you to manually control the state of the breakers in
the CLMD16 in the event of loss of NMEA 2000 network communication or for
service purposes.
To enter override mode, press and hold the OVERRIDE switch
until the green LED on the OVERRIDE switch is lit (1-2 seconds). While the
green LED on the OVERRIDE switch is lit, the state of the CLMD16 breakers is
controlled only by the individually numbered switches on the control panel, and
all network control inputs are ignored.
Each switch has an LED that will be dark when the
corresponding breaker is turned OFF and will be lit green when the
corresponding breaker is turned ON. To toggle the state of a breaker, press and
hold the corresponding breaker control switch until the LED changes state
(about
0.5 seconds).
To exit override mode, press and hold the OVERRIDE switch
until the green LED on the OVERRIDE switch is dark (about 1 second). The
breakers will immediately revert to their
automatically controlled state.
Regular maintenance is important to ensure continued
proper operation of the Maretron CLMD16. Perform the following tasks
periodically:
• Clean the unit with a soft cloth. Do not use chemical
cleaners as they may remove paint or markings or may corrode the CLMD16
enclosure or seals. Do not use any cleaners containing acetone, as they will
deteriorate the plastic enclosure.
• Ensure that the unit is mounted securely and cannot be
moved relative to the mounting surface. If the unit is loose, tighten the
mounting screws.
• Check the security of the cable connected to the NMEA
2000® connector and tighten
if necessary.
• Check the security
of all input and output
connections to the unit and tighten if necessary.
If you notice unexpected operation of the Maretron CLMD16,

Table 12 - Troubleshooting Symptoms and Check Procedure
|
Symptom
|
Troubleshooting
Procedure
|
|
No breaker/switch data visible on
NMEA 2000® network.
|
•
Ensure that the
CLMD16 is properly connected to the
NMEA 2000® network.
• Ensure that the CLMD16 instance of the breaker/switch component matches the
instance programmed into the CLMD16, as described in Advanced Tab on page 40
|
|
A breaker/switch always
reads “Error”
|
The CLMD16 may have shut down the affected channel
due to an over-temperature or over-current condition detected on the CLMD16
breaker itself.
• Ensure that the current drawn by the load is less
than the current rating for the
connected channel.
• Ensure that no short circuits or other wiring
problems exist on the load circuit, and reset the channel by turning it OFF, then ON.
•
If the breaker or switch control
returns to the error state, closely examine the load wiring for problems and ensure that the load draws the
appropriate amount of current.
|
|
A breaker/switch is “ON”, but the load is not
powered.
|
• Ensure that the load is connected to the load
terminal of the same CLMD16
channel that the breaker/switch component is
controlling.
• Ensure that the load’s terminal which is not
connected to the CLMD16 is
connected to vessel ground.
• Ensure that the connection between the breaker and the channel’s power terminal is good.
• Ensure that the breaker supplying power to the
channel is not tripped.
|
|
You can see, but not
control, the state of a breaker/switch
|
•
If you are controlling the load
via a DSM-Series display, ensure that it is running at least firmware
revision 1.4.10.
•
If you are controlling the load
via N2KView software, ensure that
you have a switch control license for the software.

Appendix A – NMEA 2000® Interfacing
This appendix is intended to relate specific characteristics
of the CLMD16 to how they are communicated via NMEA 2000 messages in order to help ascertain whether the
messaging implemented by the CLMD16 is compatible with other NMEA 2000 products. It is not a complete
description of the messages. If you require detailed information on the
messages, please obtain a copy of the NMEA 2000 standard documents from the National Marine Electronics
Association (www.nmea.org).
CLMD16 NMEA 2000 Periodic
Data Transmitted PGNs
PGN 127500 – Load
Controller Connection State/Control
The CLMD16 uses this PGN to transmit
the state of each of the breakers. A separate occurrence of this message will be transmitted for each breaker.
The state of each breaker
may be controlled by issuing a 126208 NMEA Command for this message
addressed to this device.
Field 1: Sequence ID – This field is
transmitted with a value of 255.
2: Connection ID – This field identifies the output channel
(breaker) whose status
is being reported in this
message. The value of this field will be in the range of 0 (Breaker #1) through
15 (Breaker #16).
3: State – This field indicates the state of the
solid-state breaker.
4: Status – This field indicates the status of the
solid-state breaker.
5: Operational Status & Control – This field is
used to lock and unlock the solid-state breaker.
6: PWM Duty Cycle – This field is used to control
and report the PWM duty cycle of the solid-state breaker.
7: Time ON – This
field is used to report the ON time if the solid-state breaker is running under
the control of a flash element.
8: Time OFF – This field is used to report
the OFF time if the solid-state breaker
is running under the control
of a flash element.
PGN 127501 – Binary
Status Report
The CLMD16 uses this PGN to transmit the state of each of
the breakers and connected switch
inputs. The state of the breakers may be controlled by issuing a 126208 NMEA
Command for this message addressed to this device.
Field 1: Indicator Bank Instance – This field identifies
the particular switch bank to which this PGN applies. Please refer to Instance on page 33 for instructions on how to
program the value of this field.
2: Indicator #1 – This field indicates the state of the solid-state breaker on output channel
#1. The state will be one of the following values:
•
“OFF” – The breaker is open – no
current is supplied to the load.
•
“ON” – The breaker is closed –
current is supplied to the load.
•
“Error” – The breaker is open due
to an error condition.
3 to 16: indicates the state of the solid-state breaker on outputs
on channels 2 to 16 respectively.
18: Indicator #17 – This field indicates the state sensed
by the digital input on input channel #1. The state will be one of the
following values:
“OFF” – The digital input voltage level is
outside the range(s) programmed for “ON” levels
“ON” – The digital input voltage level is
inside the range(s) programmed for “ON” levels
Please refer to Input
Monitor on page 22 for details
19 to 25: Indicates the state sensed
by the digital input on input channel 2 to 8 respectively.
PGN 130314 – Actual
Pressure
The CLMD16 uses this PGN to provide
a regular transmission of various pressures. The factory default
for periodic transmission rate is once every two seconds. The transmission of
this PGN can be disabled (see PGN 126208 – NMEA Request Group Function –
Transmission Periodic Rate).
Field 1: SID – The sequence identifier field is used to tie
related PGNs together. For example, the CLMD16 will transmit identical SIDs for
130312 (Temperature) and 130311 (Environmental Parameters) to indicate that the
readings are linked together (i.e., the data
from each PGN was taken at the same time although they are reported
at slightly different times).
2: Pressure Instance – The CLMD16 sets this field
to identify a particular pressure measurement from the source specified in
Field 3. Every pressure measurement from
a given source type on the network should have a distinct instance value, so
that monitoring devices and displays can identify which measurement is which.
3: Pressure Source – This field is used to indicate
the type of pressure measurement being taken. Possible values for this field
include Atmospheric Pressure, Water Pressure, Steam Pressure, Compressed Air
Pressure, Hydraulic Pressure, and 16 User Defined pressure sources.
4: Pressure – This field is used to indicate
the pressure, whose source is specified in field
2, in units of 0.1 Pa.
6: Reserved bits – The CLMD16 sets all bits in this
field to a value of “1”.
PGN 127505 – Fluid Level
The CLMD16 uses this PGN to indicate the attached tank’s
fluid instance, fluid type, fluid level, and tank capacity.
Field 1: Fluid Instance – This field is used to identify
the tank number and ranges between 0 and 15. There
can be up to 16 tanks of a given type as defined by the Fluid Type field. This field is programmable through
the NMEA command PGN. The CLMD16 ships from the factory with a default value of zero.
2: Fluid Type – This field identifies the type of
fluid contained within the tank. Currently the defined fluid types are fuel,
fresh water, wastewater, live well, oil, and black water. This field is programmable through the NMEA command PGN.
The CLMD16 ships from the factory with a default value of 0x0 indicating “Fuel”.
3: Fluid Level – This field is used to indicate the
current fluid level in percentage. The value
transmitted in this field depends
on the distance from the sender to the top of the fluid or tank bottom.
4: Tank Capacity – This field is used to indicate
the tank capacity. This field is programmable
through the NMEA command PGN. The CLMD16
ships from the factory
with a default value of 0xFFFFFFFF indicating “Data Not Available”.
5: Reserved – This field is reserved by NMEA;
therefore, the CLMD16 sets all bits to a logic 1
PGN 127751 – DC
Voltage/Current
The CLMD16 uses this PGN to transmit DC voltage and
current information.
Field 1: Sequence ID – This field is transmitted with a
value of 255.
2: Connection ID – This field identifies the output channel
(breaker) whose status
is being reported in this
message. The value of this field will be in the range of 0 (Breaker #1) through
15 (Breaker #16) or 16 (Analog / Digital Input #1) through 23 (Analog / Digital Input #8)
3: DC Voltage – This field indicates the DC voltage
sensed on the load or analog/digital input pin
4: DC Current
– This field indicates the DC current
sourced by the load (this field shall
be set to “Data Not Available” for analog/digital inputs
5: Reserved bits – The CLMD16 sets all bits in this
field to a value of “1”
