WARNING
·
Removal of CLMD12 cover in the field will compromise the
operation of the unit and voids warranties set forth by Carling Technologies.
|
Congratulations
on your purchase of the Maretron MPower CLMD12 12 Channel DC Load Controller Module.
Carling has designed and built your CLMD12 to the highest standards for years
of dependable and accurate service.
The Maretron CLMD12 contains 12 breaker outputs implemented
by direct current (DC) Electronic Circuit Breakers (ECB’s), each capable of
switching up to 5, 10, or 12 Amps, with a total current capacity of 75 Amps. In
addition to fast switching, low-loss solid state ON/OFF switches, it provides
accurate current measurement for each load along with short circuit protection.
The CLMD12 additionally contains 7 (Hardwired) inputs
implemented by DC digital inputs, programmable to sense whether the input is
connected to a high level (DC+), connected to a low level (DC -), or left
unconnected.
The CLMD12 connects directly to an NMEA 2000®
network, so you can turn on and off the breaker outputs from a Maretron DSM-Series
display or any device running Maretron N2KView® software, such as
TSM-Series multifunction displays or MBB-Series black boxes. Additionally,
since the CLMD12 supports standard NMEA 2000® messages for control,
it can be controlled by any NMEA 2000® device supporting those
messages. The CLMD12 easily handles resistive DC loads like lights or inductive
DC loads like pumps and motors. The CLMD12 can also be used to switch AC
circuits using external relays. An added benefit of the CLMD12 is that it
reports the current through each of the 12 breakers. This allows you to
determine if loads are drawing too little electrical current such as burnt-out
bulbs, or if the loads are starting to draw too much electrical current.
The CLMD12 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. For best results, please read this user’s manual from start
to finish to understand instructions for installation, configuration, and usage
of the CLMD12.

Installing the Maretron CLMD12 involves the following steps.
Please refer to the individual sections for additional details.
1. Unpack the
box (Section 0)
2. Choose a
mounting location (Section 0)
3. Mount the CLMD12
(Section 0)
4. Connect
the CLMD12 (Section 0)
5. Configure
the CLMD12 (Section 0)
The CLMD12 provides the ability to turn on or off DC power
to a load circuit using 12 independent solid-state Electronic Circuit Breakers
(ECB’s). Each breaker contains protection against overcurrent, overtemperature,
and short circuit.
Each breaker in the CLMD12 may be controlled using any of
the following methods:
1) Maretron N2KView®
software running on a personal computer, or
2) Maretron N2KView®
software running on a Maretron MBB-Series Black Box for Vessel Monitoring and
Control, or
3) Maretron N2KView®
software running on a Maretron TSM-Series Vessel Monitoring and Control Touchscreen
Computer, or
4) Maretron N2KView®
Mobile app running on an Android or iOS tablet or phone, or
5) a Maretron DSM-Series
NMEA 2000® Multi-function Color Graphic Display, or
6) any NMEA 2000®-connected
switch, such as an Maretron MPower CKM-Series network-connected keypad or VMM-Series
network-connected switches, or
7) any NMEA 2000®
product that can transmit standard NMEA 2000® control messages such
as a compatible third party MFD (Multi-function Display)
(please refer to Appendix A for
details on the required messaging).
The breakers can be monitored and/or controlled 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 NMEA 2000 power is removed, all breakers will revert
to the open (OFF) state. The state that the breaker will be in when the NMEA
2000 power is restored can be configured to be ON, OFF, or in the last state
the breaker was in before power was removed.
The 12 breaker outputs are switched with MOSFETs connected
in a back-to-back arrangement so that back-feeding is not possible when the
breaker is turned off.
All breaker outputs employ the following:
·
Latched shutdown overcurrent detection with reset
·
Overcurrent surge allowance that prevents overcurrent latch tripping
when starting high surge loads such as incandescent lamps
The table below shows the connection and maximum current
capacity for each Breaker.

– Breaker Output Schematic
Breaker
Overcurrent protection
The overcurrent protection has two purposes: to protect the
CLMD12 and to protect connected breaker loads. The CLMD12 is protected by fast
acting overcurrent latches in hardware that allow for overcurrent conditions
that will not damage the breaker output control circuit. Load protection is
implemented in software and trip levels and delays are set in configuration
(please refer to Section 0 for details).
When an overcurrent condition is detected, the CLMD12 will
latch the breaker off for the remainder of the continuously powered interval
unless reset by being commanded OFF and then ON again through the NMEA 2000
interface.
The non-configurable breaker output control circuit
protection allows surge currents to occur without tripping the overcurrent
shutdown function. These surges are allowed any time the breaker is ON
according to a single time constant characteristic. Over-current levels are
allowed for a time that is inversely proportional to the magnitude of
overcurrent according to a well-defined curve that is tailored to prevent
damage to the CLMD12. This protection cannot be disabled and will trip
instantaneously when a peak limit is exceeded. Continuous load currents above
the hard current limit will also trip the overcurrent latch.

The configurable breaker load protection current limit
provides three parameters to customize the overcurrent protection of the load.
·
Current rating: Constant load current above this level will trip
the breaker OFF.
·
Inrush Delay: An adjustable delay (0 to 1500 milliseconds) that
starts at the time of breaker turn ON. The configurable current limit trip is
blocked during this period.
·
Trip Delay: An adjustable delay (0 to 750 milliseconds) that
starts when currents exceeding the current rating setting are detected after
the Inrush Delay has expired. The configurable current limit trip is blocked during
this period.
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 with a duty cycle of 5% to 100%
with a resolution of 1%.
|
|
WARNING
·
The breaker being used as a dimming module will provide an
output at full battery voltage to the LED control module. Verify that the LED
control module can accept this type of input prior to use. When a breaker is
configured to provide a PWM output (dimming), the PWM frequency is 200Hz.Use
of a breaker in a PWM mode (duty cycle less than 100%) for control of motors
or other inductive loads is prohibited.
|
Breakers can be paralleled for higher current capacity:
·
Only parallel two breakers with the same current rating.
·
Wiring recommendation: Run two breakers wired together with
matched impedance.
·
Please note that the maximum current rating when two breakers are
paralleled is typically 180% of the single channel rating. (Example: 18A
maximum for two 10A breakers in parallel). This is because the impedance of the
two paralleled breakers will not be identical due to component variation.
·
See tables below for recommended parallel breakers:

You can parallel two breakers by assigning the same switch
group number to the two breakers.
When you parallel breakers, configure the CLMD12 to assign
50% of the maximum current to the Current Rating parameter for each of the two
paralleled breakers. For example, if you parallel Breaker #7 and Breaker #4 and
wish to use them to supply power to a load rated at 22A, configure the Current
Rating for each of the two breakers to 12A. This will result in a typical
maximum current rating of 22A for the paralleled breakers.
The hardwired inputs respond to
three voltage level states, “Active High”, “Open” and “Active Low”. That is,
when the input is at V-Battery (Connected to DC (+) it will
be read as a “High”. When the input is at 0 V or GND (Connected to DC (-) it
will be read as “Low”. The unused inputs can
be left disconnected which results in an “open” state.
The following diagram shows the impedance model of the Hardwired
Inputs.
Figure 2 – Hardwired Input Impedance
Model
Each hardwired input can be configured to output an ON
indication in the NMEA 2000 127501 Binary Status Report PGN when the input
voltage level is sensed as Low, High, or Both (Low and High). If the input
voltage level is not one of the configured levels, then the input channel will
output an OFF indication in the NMEA 2000 127501 Binary Status Report PGN.
When unpacking the box containing the Maretron CLMD12,
you should find the following items:
1 – CLMD12 – 12 Channel DC Load Controller
Module
1 – Maretron Blue USB Disc containing
User’s Manuals
1 – CLMD12 Quick Start Guide
1 – Warranty Registration Card
If any of these items are missing or damaged, please
contact Carling.
Please consider the following
when choosing a mounting location.
- The CLMD12 is waterproof, so it
can be mounted in a damp or dry location.
- The orientation is not
important, so the CLMD12 can be mounted horizontally, or vertically.
- The CLMD12 is temperature-rated
to 85°C (185°F), so it should be mounted away from engines or engine rooms
where the operating temperature exceeds the specified limit.
Attach the
CLMD12 securely to the vessel using mounting screws or other fasteners through
the three provided mounting holes. Do not use thread locking compounds
containing methacrylate ester, such as Loctite Red (271), as they will cause
stress cracking of the plastic enclosure.
The CLMD12 requires four types of electrical connections, as
shown in Figure 3 below:
1) The NMEA 2000® connection (J3)
2) The output channel (breaker) connections (J1)
3) The hardwired discrete input signal connections and unit
main ground (J2)
4) The DC main power connection stud
Figure 3
– CLMD12 Side View
The NMEA 2000®
connector can be found on the bottom of the enclosure labeled “J3”. The NMEA
2000® connector is a round five-pin male connector (see Figure 4). You connect the CLMD12 to an NMEA 2000® network using a
Maretron NMEA 2000® cable (or compatible cable) by connecting the female
end of the cable to the CLMD12 (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 CLMD12
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.
Figure 4 – NMEA 2000® Connector (J3) Face
Views
The CLMD12 breaker output connections are made by connecting
to the 12-pin ‘J1’ connector. The pin number on the ‘J1’ connector corresponds
to a breaker number, which is represented as an indicator number in the NMEA
2000 127501 Binary Status Report PGN message or as a Connection ID in the NMEA
2000 127500 Load Controller Connection & State PGN message. The
correspondence of the ‘J1’ connector pin number to the breaker number is
detailed in the table below, along with the maximum current supported by the breaker.

WARNING
The System Ground signal (Connector J2, Pin 6) must be
connected to the supply voltage ground reference for proper system operation,
regardless of whether any of the Discrete Input signals are connected. A
14awg. wire is recommended for this connection to the supply source up to
100ft.
|
Connect a source of DC (+) with a ring terminal to the
1/4”-20 stud on the top of the device, being careful not to torque the
connection beyond the specified value of 20 in-lbs. (2.26 N·m). Ensure that the
cable providing the DC (+) signal is protected by a fuse or circuit breaker
with a value appropriate to protecting the wire or the 75A maximum
specification of the CLMD12, whichever is less.
Note: Multiple CLMD12 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 75A (The maximum specification of the CLMD12) and
the feeder wire to each unit is sized identically.
Checking Connections
Once all of the connections to the CLMD12 have been
completed, check to see that information is being properly transmitted by
observing an appropriate NMEA 2000®
display. If you don’t see channel on/off status, refer to Section 0, “Troubleshooting”.
The CLMD12 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 CLMD12, which are detailed in the remainder of
this section.
Configure CLMD12 using Maretron
N2KAnalyzer® V3 software. The following subsections describe the
configurable parameters in the CLMD12.
This tab contains commonly-used configuration items.
Figure 5 – CLMD12 General Tab
Label
This text box allows you to assign a text label to the
device. This label is visible in Maretron
analysis and 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 CLMD12 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.
Input Voltage
This field allows you to configure nominal expected input voltage
of the CLMD12. Choose from one of the following selections:
·
12 VDC
·
24 VDC
·
36 VDC
·
Undefined
Not Configured
When lit, this read-only field indicates that the CLMD12
does not contain a valid configuration.
Serial Number Invalid
When lit, this read-only field indicates that the CLMD12
does not contain a valid serial number. Please contact Maretron technical
support for assistance.
This section contains settings for the specified 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.
State
This read-only field indicates the current state of the
breaker. It will contain one of the following values:
·
OFF
·
ON
Default State
This allows you to configure the state of the breaker when
the CLMD12 is powered on. You can set this to one of the following values:
·
OFF
·
ON
·
LAST KNOWN STATE
Default Lock State
This parameter allows you to configure whether the breaker
is locked when the CLMD12 is powered on. You can set this to one of the
following values:
·
LOCKED
·
UNLOCKED
Sound Alarm When Tripped
This parameter allows you to configure whether an alarm is
sounded on OctoPlex and Maretron branded Touch Screen displays whenever the
breaker is tripped.
Trip Delay
This parameter allows you to configure the trip delay for
the breaker (the current through the breaker must exceed the current rating of
the breaker for this amount of time for the breaker to trip). This can be set
in the range of 0 ms to 750 ms.
Inrush Delay
This parameter allows you to configure the inrush delay for
the breaker. When the breaker is switched from OFF to ON, the current through
the breaker can exceed the current rating of the breaker for this amount of
time without the breaker tripping. This allows for a brief period of current
inrush, preventing the circuit from inadvertently tripping when energized. This
can be set in the range of 0 ms to 1500 ms.
Default Dim Value
This parameter allows you to configure the percent dimming
value for the breaker when the CLMD12 is powered on. This value will be applied
only if the Dimming Allowed box is checked. This can be set in the range of 5%
to 100% with a resolution of1%.
Current Dim Value
This read-only field shows the percent dimming value for the
breaker.
Dimming Allowed
This parameter allows you to configure whether the channel
is dimmable. Check this box to allow dimming commands to change the dimming
level of the breaker and clear this box to force the breaker to operate at 100%
dimming level.
Combine With
To parallel two breakers, select the number of the breaker
you wish to combine this breaker with. The dropdown box will present a list of
other breakers with the same current capability which may be paralleled with
this breaker, If two breakers are paralleled, the breaker with the higher
number mirrors the state of the breaker with the lower number. For example, if
you parallel Breaker 1 and Breaker 2, any change in state of Breaker 1 will be
mirrored by Breaker 2.
Factory Current Rating
This parameter allows you to configure the maximum value to
which the Current Rating can configured. This parameter should be configured to
the current rating for the wire connected to this breaker. The value you can
program into this field is limited by the current capacity of the channel being
programmed.
Current Rating
This parameter allows you to configure the desired trip
level for this breaker. Exceeding this current will initiate a trip. The value
you program into this field will be limited by the value in the Factory Current
Rating field.
Current
This read-only field shows the real-time current passing
through the breaker.
Voltage
This read-only field shows the real-time voltage at the load
terminal of the breaker.
Flash Map
This parameter allows you to configure a breaker to use a
flash map. A value of 0 means that the breaker is not assigned to any flash
map, and a value of 1 through 15 assigns the breaker to the flash map
corresponding to that number.
User Config Allowed
This parameter allows you to configure whether configuration
changes can be made to the breaker. If this is checked, other configuration
parameters for the breaker can be changed. If this is cleared, other
configuration parameters for the breaker cannot be changed.
Status
This group of indicators show real-time status of the
breaker.
Short Load
When lit, this read-only field indicates that the breaker has
tripped due to a detected short circuit.
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.
Breaker Tripped
When lit, this read-only field indicates that the breaker
has tripped due to an overcurrent condition. Switch the breaker OFF to
acknowledge the ‘breaker tripped’ indication. You can then switch the breaker
back to the ON position.
Breaker ON
When lit, this read-only field indicates that the breaker is
in the ON state.
Open Load
When lit, this read-only field indicates an Open Load (no
load) condition which indicates that the breaker is turned ON but there is
little or no current being drawn. Possible conditions:
·
External switch controlling load is in the OFF position

When lit, this read-only field indicates that the breaker has
lost communication with the main processor.
Breaker Communicating
When lit, this read-only field indicates that the breaker is
communicating with the network.
The Flash Function allows control of a breaker to be
periodic. Common uses of this function include turning off a head fan or light
after a set period of time, etc. Five parameters dictate the behavior of the
circuit and are detailed below. A maximum of 15 flash table entries may be
defined.
Figure 6 – CLMD12 Flash Map Tab
Cycles
This parameter allows you to configure the number of cycles
that this flash map will execute after a breaker configured to use this flash
map has been switched to the ON state. A value of 0 will repeat the cycle
indefinitely, and values in the range of 1 cycle to 255 cycles will execute
that number of cycles.
On Time
This parameter allows you to configure the time that a
breaker will be ON during a cycle. This can be set to a value in the range of 0
seconds to 6553.5 seconds in increments of 0.1 seconds.
Off Time
This parameter allows you to configure the time that a
breaker will be OFF during a cycle. This can be set to a value in the range of
0 seconds to 6553.5 seconds in increments of 0.1 seconds. A value of 0 will
disable this flash map.
This parameter allows you to configure the Flash Map to
start with ‘Off Time’ as the first behavior of the Flash Map. The Flash Map
will then execute the configured number of Cycles.
Finish Flash Cycle in On State
This parameter allows you to configure the Flash Map to stop
the flash cycle with the breaker to finish in the On state once the configured
number of cycles are executed.
When a device transmitting the 127501 Binary Status Report
message is part of the installation, it can be configured to control the
behavior of the breakers. This includes the the seven hardwired inputs present
on the CLMD12. Up to thirty-six (36) total Discrete I/O’s can be programmed
into one CLMD12. One Discrete I/O can control multiple breakers, or because the Discrete I/O state is maintained independent
of any breaker state a breaker can be controlled from multiple Discrete I/O input
signals. Example: two separately wired wall switches are controlling the same
light (breaker).
Figure 7 – CLMD12 Discrete I/O
Tab
Data Instance
This parameter allows you to configure the data instance of
the 127501 Binary Status Report message that will be used to control this
discrete I/O circuit. To assign a discrete input from this device to this discrete
I/O circuit, enter the instance value assigned to this device (the value of the
“Instance” field on the “General” tab).
Indicator
This parameter allows you to configure the indicator number
within the 127501 Binary Status Report status message whose instance field
matches the “Data Instance” parameter for this channel that will be used to
control this discrete I/O circuit.
Manufacturer Code
This parameter allows you to configure the manufacturer code
that must be reported by the device transmitting the 127501 Binary Status
Report message that will be used to control this discrete I/O circuit. Setting
this value to 2047 means that any manufacturer code will be accepted.
Discrete I/O Function
This parameter allows you to configure how the specified
127501 Binary Status Report indicator will control the assigned breaker. The
following functions may be selected:

the breakers.
The CLMD12 has seven digital inputs. These inputs correspond
with the ‘Hardwired Inputs’ described in the 0 section of this manual. These
Inputs are configured on the Inputs tab. The states of these input channels are
transmitted in a 127501 Binary Status Report message as indicators 13 (Input
Channel #1) through 19 (Input Channel #7).
Figure 8 – CLMD12 Inputs Tab
Instance
This read-only field indicates the data instance used for
this box. The value that appears here can be changed by setting the “Device
Instance” parameter on the Advanced tab.
Input #n / Channel
This Read-Only field indicates the input’s number associated
with the CLMD12 hardware and then the Input’s “Channel / Indicator #”
associated with the NMEA 2000 PGN 127501 ‘Binary Status Report’ message
transmission.
Label
Each channel has a text label you can set to identify the
input signal monitored by that channel (for example, “BILGE PUMP” or “HATCH”).
For each channel, set this to a value which describes the input being monitored
so that you can easily identify it in display devices.
This parameter allows you to configure the voltage level input
on the input signals that corresponds to an ON status in the NMEA 2000 PGN
127501 ‘Binary Status Report’ reported on the network. You can use any of the
following settings:
·
High – a high voltage level on the input (Connected to DC (+)) is
represented as an ON value on the network. A high impedance or a low voltage
level on the input is represented as an OFF value on the network.
·
Low – a low voltage level (Connected to DC (-)) on the input is
represented as an ON value on the network. A high impedance or a high voltage
level on the input is represented as an OFF value on the network.
·
Both – a high voltage level or a low voltage level on the input
is represented as an ON value on the network. A high impedance on the input is
represented as an OFF value on the network.
State
This read-only field represents the current state of the
input signal as reported on the network.
Transmit Battery Voltage
This dialog box is where you would enable and disable
transmission of the NMEA 2000 PGN 127508 ‘Battery Status’ message transmission.
The transmission value will replicate the battery voltage sensed on the
corresponding hardwired input. Use this data to enable Battery Voltage Gauges
on MFDs (Multi-Function Displays).
Battery Instance
This scroll box allows you to choose a unique instance of
the input’s battery voltage transmission in the NMEA 2000 PGN 127508 ‘Battery
Status’ message transmission when ‘Transmit Battery Voltage’ dialog box is enabled.
The Advanced tab is used to configure and observe parameters
that do not normally require changing.
Figure 9 – CLMD12 Advanced Tab
This parameter allows you to configure
the NMEA 2000 device instance used by the device. This value is also used as
the data instance in the 127501 Binary Status Report messages transmitted by
the device and can be seen on the General Tab as well as the Inputs Tab labeled
as “Instance”.
Transmit PGN 127501
This parameter allows you to configure whether the device
transmits the 127501 Binary Status Report NMEA 2000 message. If this field is
set, the device will transmit the 127501 Binary Status Report message along
with proprietary messages. If this field is cleared, the device will not
transmit the 127501 message and will transmit only proprietary messages.
Receive PGN 127501 via 126208
This parameter allows you to configure whether the device
will respond to the NMEA command of an indicator in the 127501 Binary Status
Report message. If this field is set, the device will respond to that message.
If this field is cleared, the device will not respond to that message, but only
to proprietary messages.
Transmit 127508
This parameter allows you to configure whether the device
will transmit the 127508 ‘Battery Status’ message to indicate the box
temperature, input voltage, and input current. If this field is set, the device
will transmit the 127508 message. If this field is cleared, the device will not
transmit the 127508 message.
Send Extended Status
This parameter allows you to configure when the CLMD12 sends
the extended box status proprietary message. There are two settings for this
parameter:
·
Only send when an error is detected
·
Only send upon request
127501 via 126208 Receive Filter
This parameter allows you to configure from which devices
the CLMD12 will accept 126208 NMEA Commands of the 127501 Binary Status Report
message. There are two settings for this parameter:
·
From Carling/Maretron devices only
·
From any manufacturer’s device

input for the device.
This tab allows you to set values for the installation
description properties of the device.
Figure 10 – CLMD12 Installation
Description Tab
Installation Description #1, #2
This device, along with all other certified NMEA devices,
has two user-programmable installation description fields. You may program
these fields with information specific to the device, such as date installed,
the initials/name of the installer, the physical location of the device, etc.
This configuration option will allow you to program the values of these fields.
Control Tab
This tab allows you to control the ON/OFF state and dimming level
of the breakers on the device. This is normally used for testing purposes.
These controls mimic the available controls of an NMEA 2000 Network Input for
any given CLMD12 breaker.
Figure 11 – CLMD12 Control Tab
Status LED
When lit, this read-only field indicates that the breaker is
in the ON state. When dim, this field indicates that the breaker is in the OFF
state.
ON/OFF Buttons
The ON button allows you to switch the breaker into the ON
state. The OFF button allows you to switch the breaker into the OFF state.
Dimmer Slider
The blue slider bar allows you the configure the dimming
level of a breaker between 5% and 100%. The read-only green bar graph shows the
real-time dimming level of the breaker.
Breakers may be manually turned on and off via messages
received over the NMEA 2000 network.
The Flash Function allows control of a breaker to be
periodic. Common uses of this function include controlling a foghorn,
automatically turning off a head fan or light after a set period of time, etc.
Three parameters dictate the behavior of the circuit and are set via the Maretron
N2KAnalyzer utility. A maximum of 15 flash table entries may be defined.
·
Flash ON time: Duration of time the load is ON
·
Flash OFF time: Duration of time the load is OFF
·
Number of Cycles: Number of times to repeat the cycle – 0 to 255
(0 will cause the cycle to be repeated indefinitely)
When a device which transmits a 127501 Binary Status Report
message is present on the NMEA 2000 network or internal hardwired inputs are
utilized, the indicator states transmitted in these messages can be configured
to control the behavior of the breakers. Up to thirty-six (36) total Discrete
I/O inputs per CLMD12 can be programmed. One Discrete I/O can control multiple breakers,
or because the Discrete I/O state is maintained independent of any breaker
state, a breaker can be controlled from multiple Discrete I/O input signals.
Example: two separately wired wall switches are controlling the same light
(breaker).

Manual Bypass
The Maretron Mechanical Bypass Module (CBMD12) P/N A3675 can
be installed in conjunction with the CLMD12.
The bypass module provides a manual method (On/Off switch) to
control loads by providing power to each load in case of CLMD12 malfunction
and/or NMEA 2000 network failure. The power outputs provided by the bypass
module are over current protected via an individual fuse for each output.
Please ensure that the current rating of the fuse for each load is appropriate
to protect the load and the wiring for that load.
Please note that the bypass module does not support
paralleled outputs, since each circuit is controlled by a separate switch.
Additionally, the bypass module does not support dimming of circuits.
|
|
WARNING
The CBMD12 Mechanical Bypass Module is not ignition
protected. Ensure that the area is free of fumes and gasses when the switches
are cycled and when fuses are removed and/or installed.
|
To change control from the CLMD12 load module to the CBMD12 bypass
module, please perform the following steps:
1) Ensure that the
area is free of fumes and gasses.
2) Ensure that all
switches on the CBMD12 bypass module are in the OFF position.
3) Connect power to
the ¼”-20 power stud on the CBMD12 bypass module.
4) Unplug the J1
connector from the CLMD12 load module.
5) Plug the J1
connector into the CBMD12 bypass module.
6) For the circuits
you wish to energize, set the corresponding switches on the CBMD12 bypass
module to the ON position.
Please refer to the diagram of how the bypass module is
installed below in Figure 12.
Figure 12 – Bypass Module Usage
Maintenance
|
|
WARNING
The CLMD12 DC 12 Channel Load Module is operated under
remote control. Before servicing any load device connected to the CLMD12, you
must first disconnect the wire between the CLMD12 load terminal and the load
device. Failure to do so can result in serious bodily harm.
|
Regular maintenance is important to ensure continued proper
operation of the Maretron CLMD12. 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 CLMD12 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 of
the input and output connections to the unit and tighten if necessary.
If you notice unexpected
operation of the Maretron CLMD12, follow the troubleshooting procedures in this
section to remedy simple problems. If these steps do not solve your problem,
please contact Maretron Technical Support (refer to Section 0
for contact information).
|
Symptom
|
Troubleshooting
Procedure
|
|
No breaker/switch data visible on NMEA 2000®
network.
|
- Ensure that the CLMD12 is properly connected to the NMEA
2000® network.
- Ensure that the CLMD12 instance of the breaker/switch
component matches the instance programmed into the CLMD12, as described
in Section 0.
|
|
A breaker/switch always reads “Error”
|
The CLMD12 may have shut down the affected channel due to
an overtemperature or overcurrent condition detected on the CLMD12 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 CLMD12 channel that the breaker/switch component is
controlling.
- Ensure that the load’s terminal which is not connected
to the CLMD12 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.

assumes no liability whatsoever for expenses of removing any defective product
or part or for installing the repaired product or part or a replacement
therefore or for any loss or damage to equipment in connection with which Maretron®

Carling’s warranty obligation shall in all respects conform to and be limited
to the warranty actually extended to Carling by its supplier. The foregoing
warranties shall not apply with respect to products subjected to negligence,
