1 Introduction
Congratulations on your purchase of the Maretron DC
Relay Module. Maretron has designed and
built your DCR100 to the highest standards for years of dependable and accurate
service.
Maretron's DCR100 contains 6 Direct Current (DC) relays,
each capable of switching up to 10 Amps. The DCR100 connects directly to an
NMEA 2000® network, so you can turn on and off the relays from a
Maretron DSM150 or DSM250 display or any device running Maretron’s N2KView®
software. The DCR100 easily handles
resistive DC loads like lights, or inductive DC loads like pumps and motors.
The DCR100 can also be used to switch AC circuits using external relays. An
added benefit of the DCR100 is that it reports the current through each of the
six channels. 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 DCR100 may also be used to connect
annunciators, such as horns or lights, to an NMEA 2000 network for use with
N2KView® alerts.
The Maretron DCR100 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 DCR100
in order to ensure optimal performance.

Quick Install
Installing the Maretron DCR100 involves the following five
steps. Please refer to the individual sections for additional details.
1.
Unpack the box (Section 2.1)
2.
Choose a mounting location (Section 2.2)
3.
Mount the DCR100 (Section 2.3)
4.
Connect the DCR100 (Section 2.4)
5.
Configure the DCR100 (Section 2.5)
1.4 Theory
of Operation
The DCR100 provides
the ability to turn on or off DC power to a load circuit using 6 independent,
isolated solid state relays. The DCR100 is a solid state relay, not a circuit
protection device. Each channel contains protection against overcurrent, over
temperature, and short circuit. These protections are intended to protect the
DCR100, and not the load or the associated wires. Each power source supplying
power to a device which is controlled by the DCR100 must be individually
protected by a circuit breaker. The circuit breaker must be sized appropriately
for the size of the wire from the circuit breaker to the DCR100 and from the
DCR100 to the load device. In addition, the circuit breaker must be no larger
than 10A.
Each channel of the
DCR100 may be manually switched on or off using any of the following methods:
1)
Maretron’s N2KView® software running
on a personal computer*, or
2) Maretron’s
N2KView® software running on a Maretron MBB100 or MBB200C Black Box
for Vessel Monitoring and Control*, or
3)
Maretron’s N2KView® software running
on a Maretron DSM800, TSM800C, or TSM1330C Vessel Monitoring and Control Touchscreen
Computer,
4) a
Maretron DSM150 or DSM250 NMEA 2000®
Multi-function Color Graphic Display, or
5) an
Android or iOS tablet or phone running N2KView Mobile*
The switches 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 channel may be monitored through the
Breaker/Switch Current component in the Electrical Distribution category of
Maretron display products.
Since the channels
are solid state relays, if the NMEA 2000 power is removed, all switches will
revert to the open (OFF) state. The state that the switch will be in when the
NMEA 2000 power is restored can be configured to be ON, OFF, or in the last
state the switch was in before power was removed.
Each channel has a
hardware timer, which accumulates the elapsed time that channel is in the ON,
OFF, and ERROR states. Also, each channel has a hardware counter, which
accumulates the number of times that the channel has transitioned info the ON,
OFF, and ERROR states. These hardware timers and counters may be viewed and
reset using a Maretron display product or N2KAnalyzer software. If there is a
valid system time reference on the network, the DCR100 will record the date and
time that the timers or counters were reset.

2.1
Unpacking the Box
When unpacking the box containing the Maretron DCR100,
you should find the following items:
1 – DCR100
– DC Relay Module
1 – Parts
Bag containing 4 Stainless Steel Mounting Screws
1 – DCR100
User’s Manual
1 –
Warranty Registration Card
If any of these items are missing or damaged, please
contact Maretron.
2.2
Choosing a Mounting Location
Please consider the following
when choosing a mounting location.
- The DCR100 is waterproof, so it can be mounted in a
damp or dry location.
- The orientation is not important, so the DCR100 can
be mounted on a horizontal deck, vertical bulkhead, or upside down if
desired.
- The DCR100 is
temperature-rated to 55°C (130°F), so it should be mounted away from
engines or engine rooms where the operating temperature exceeds the
specified limit.
2.3
Mounting the DCR100
Attach the
DCR100 securely to the vessel using the included stainless steel mounting
screws or other fasteners as shown in Figure
1
below.
Do not use threadlocking compounds containing methacrylate ester, such as
Loctite Red (271), as they will cause stress cracking of the plastic enclosure.
Figure 1 – Mounting the DCR100
2.4 Connecting
the DCR100
The DCR100 requires two types of electrical connections: 1)
the NMEA 2000® connection (refer to Section 2.4.1),
and 2) the switched power connections, which are described in Section 2.4.2.
2.4.1
NMEA 2000® Connection
The NMEA 2000®
connector can be found on the side of the enclosure. The NMEA 2000®
connector is a round five pin male connector (see Figure 2).
You connect the DCR100 to an NMEA 2000® network using a Maretron
NMEA 2000® cable (or compatible cable) by connecting the female end
of the cable to the DCR100 (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 DCR100
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.

2.4.2 Switched
Power Connections
The DCR100 switched power
connections are made by connecting to the 12-pin terminal strip on the top of
the unit. First, remove the four screws
at the corners of the unit detaching the splash guard from the unit. On the bottom of the splash guard, you will
find a label detailing the wire connection to pin number assignments, which are

2.4.2.1 Protection
|
|
WARNING ·
Each power connection to the DCR100 must be
individually protected with a fuse or circuit breaker which is sized to match
the wire between the breaker/fuse panel and the DCR100, and between the
DCR100 and the load. This fuse or circuit breaker must be sized to be no
larger than 10A. For example, if you are using all six channels of the DCR100, there
must be 6 circuit breakers and a separate power lead from each circuit breaker
to the Px terminal for each
channel. |
The power “Px”
terminals must always be connected to the circuit-breaker protected power
source (which can be wither 12VDC or 24VDC), and the load “Lx” terminals must always be connected to
the power terminal on the load. The other terminal of the load must be
connected to vessel ground. This figure shows the connection of a power and
load connections to the DCR100.
Figure 3 – DCR100 Connection Diagram
2.4.3 Checking Connections
Once the NMEA 2000® connection
and switched load connection(s) to the DCR100 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 4,
“Troubleshooting”.
2.5
Configuring the DCR100
The DCR100 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 switch monitored. There are
several configurable items within the DCR100, which are detailed in the
remainder of this section.
You configure the ACM100 using Maretron
N2KAnalyzer® software or a Maretron DSM150/DSM250 display or other
NMEA 2000® display unit that is capable of configuring the ACM100.
Please refer to the Maretron N2KAnalyzer
User’s Manual, DSM150 User’s Manual,
or DSM250 User’s Manual, as
appropriate, for details.
2.5.1
Advanced Configuration…
Certain
parameters do not normally need to be set in order for normal operation, but
are included in an advanced configuration section for use in special
situations.
2.5.1.1
Current Sensor Zero Offset Calibration
The current sensor readings from each
channel may occasionally drift such that you see small positive or negative
current readings from a channel even though no current is flowing. If this
happens, choose this menu option to calibrate the zero offset for the current
sensors for all six channels of the DCR100. Performing this calibration will
place all channels into the “OFF” state.
2.5.1.2 Device
Instance
NMEA
2000® provides a unique device instance for each switch monitoring
device on a vessel. This value should be programmed in each DCR100 so that each
DCR100 is associated with a unique device instance number. The default instance
number is 0, which is used to indicate the first DCR100 that is hooked to the
network. Subsequent DCR100s connected to the network would be numbered 1, 2,
and so on.
2.5.1.3
Installation Description
You can configure the two installation
description parameters with any text you wish. Examples include date of
installation, location, etc. NMEA 2000 diagnostic tools such as Maretron
N2KAnalyzer® can display this information.
2.5.1.4
NMEA 2000® PGN Enable/Disable
The DCR100 is capable of
transmitting NMEA 2000® messages (or PGNs) associated with monitored
switch circuits. You may individually enable or disable each of these messages.
You may also change the rate of transmission of each of these messages if
desired.
2.5.1.5 Restore
Factory Defaults
Selecting this configuration option causes all stored
parameters in the DCR100 to be reset to the values they contained when the unit
was manufactured.
2.5.2
Device Label
Program this parameter with a text string which identifies
this particular DCR100, to allow you to easily distinguish it from other
DCR100’s on the network.
2.5.3
Instance
Program this parameter with the instance of the switch bank
controlled by this DCR100. Each switch bank should be programmed with a unique
number. This number is used by a display device to distinguish the switches
controlled by this DCR100 from switches controlled by other devices on the
network.
2.6 Channel
#x…
2.6.1
Label
Each channel has a
text label you can set to identify the load controlled by that channel (for
example, “EXHAUST FAN” or “NAV LIGHTS”). For each channel, set this to a value
which describes the load being controlled so that you can easily identify it in
display devices.
2.6.2
Operating Mode
Each channel can be
operated in one of two modes:
·
Normal: the channel operates as a standard NMEA
2000 switch. It can be controlled via N2KView or a DSM150/DSM250 or other NMEA
2000 display with standard NMEA 2000 commands
·
Alert/Annunciator: the channel operates as an
annunciator, similar to the Maretron ALM100. This allows you to connect a
light, horn, bell, siren, or other warning device to the channel and actuate it
from N2KView or a DSM150/DSM250 display in the case of an alert.
The remaining configurable
parameters differ depending on which operating mode is select for the channel.
These are described in the following subsections.
2.6.2.1 Normal
Mode Configurable Parameters
These items are
configurable only when the channel is set to “Normal” mode.
2.6.2.2 Switch
Lock
For safety critical
situations or other situations where you don’t want a switch channel’s state changed,
you can use this parameter to set the switch from an “Unlocked” (normal) state,
in which is the switch responds normally to commands over the NMEA 2000®
network, to a “Locked” state, in which the switch will not change state in
response to any commands until it is put back into the “Unlocked” state.
You might lock a
switch into the OFF state if you are servicing equipment that is powered by
that channel, or you might lock a switch into the ON state if the channel powers
a circuit whose power must remain on.
2.6.2.3 Power
Up State
Since the switch
channels in the DCR100 are solid state relays, the switch channels will open
(OFF state) whenever NMEA 2000® power is removed.
This parameter lets
you define the state of this switch channel when the DCR100 is powered up through
the NMEA 2000® network after it has been powered down. You can chose
“ON”, in which case the switch is closed as soon as power is applied; “OFF”, in
which case the switch remains open after power is applied; or “Previous”, in
which case the switch is set to the state it held before power was removed.
2.6.2.4 Switch
Control
This menu allows you to see the current state of each switch
on the DCR100 (“On”, “Off”, or “Error”). It also allows you to set each switch
to the ON or OFF state. Setting the switch to the Off State will clear an Error
condition.
2.6.2.5 Reset
Counter
This will reset the
hardware counters for this channel. If a system time is available on the NMEA
2000® network (e.g., from a GPS), the date/time the counters were
reset will be recorded as well.
2.6.2.6 Reset
Timer
This will reset the hardware timers for this channel. If a
system time is available on the NMEA 2000® network (e.g., from a
GPS), the date/time the timers were reset will be recorded as well.
2.6.2.7 Alert/Annunciator
Mode Configurable Parameters
These items are
configurable only when the channel is set to “Alert/Annunciator” mode.
2.6.2.7.1 Annunciator
Instance
Program this
parameter with an instance for the annunciator. Each annunciator device on the
network must have a unique instance number.
2.6.2.7.2 Test
Annunciator
Select this option
to test the operation of the annunciator. Pressing this switch will cause any
connected annunciator to emit light or sound.
3 Maintenance
|
|
WARNING The DCR100 DC Relay Module is operated under remote
control. Before servicing any load device connected to the DCR100, you must
first disconnect the wire between the DCR100 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 DCR100.
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 DCR100 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 switch connections
on the top of the unit and tighten if necessary.
