CLMD16 User’s Manual __
Introduction
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 programmed to operate in half-bridge or 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 programmable 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 light or sounder 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 boxes. 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 such as burnt-out bulbs, 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.

CLMD16 User’s Manual __
Theory of Operation
The CLMD16 provides the ability to control DC power to a load circuit using 16 independent solidstate PWM capable
Electronic Circuit Breakers (ECB’s). 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 outputs on the CLMD16 are then connected to the circuits 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 in the CLMD16 may be controlled using any of the following methods:
1) Maretron N2KView ®
2) Maretron N2KView ®
software running on a personal computer*
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
(please refer to Appendix A for details).
8) Any of the 8 digital 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 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.

User’s Manual Rev. 1.8 6
CLMD16 User’s Manual __
Main DC (+) Connection
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.

Main DC (-) Connection
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

Checking Connections
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.
CLMD16
User’s Manual Rev. 1.8 14
CLMD16 User’s Manual __
NMEA 2000® Connections
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 micro 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).

Breaker (Output) Features
Soft Start
Soft Start is a function that ramps up the voltage, of an output channel when it is turned on to reduce the inrush current to the device being powered. (See:
Figure 8 - Soft Start Voltage Ramp
Soft Start ramps the voltage of the load 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%.
Pulse Width Modulation (PWM)
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.
CLMD16
User’s Manual Rev. 1.8 16
CLMD16 User’s Manual __
WARNING
The breaker being used as a dimming module will provide an active high 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 200 Hz
(channels 3-10) or 20 kHz (channels 1, 2, 11, 12). Use of a breaker in a PWM mode (duty cycle less than 100%) for control of motors or other inductive loads is prohibited, and may damage the CLMD16
Paralleling 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
17 CLMD16 User’s Manual Rev. 1.8
___________________________________________________________
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, and commands to breaker #2 will be ignored.
• Please note that dimming operation is not supported on breakers that have been configured to operate in parallel with other breakers.
When breakers are configured for parallel output, the lowest breaker number of the pair will 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 at 22 Amps, breaker #1 will need to be set to 11 Amps. Breaker #2 will become visible to show the same trip current value as breaker #1 of 11 Amps thus the trip current for the paralleled breakers will be 22 Amps.
Half Bridge Operation
12 Amp Breakers #1, #2, #11, and #12 can be configured as half-bridge breakers. In the OFF state, they can connect the load to ground as opposed to becoming high impedance. When in half-bridge mode, the channels can be used to control electric motors and be used to perform braking on the motors by connecting the motor lead to ground when the load channel is turned off.
The PWM frequency in half-bridge operation is fixed at 20 kHz.
In half-bridge mode, Breakers #1 and #2 support PWM operation with a duty cycle of 5% to 90%, programmable in 1% increments. Breakers #11 and #12 do not support PWM operation in halfbridge mode.
Full Bridge Operation
12-amp breakers 1 and 2, and 11 and 12, can be configured to offer polarity reversing capability using the two half bridge circuits together. 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 and its benefits VS an analog H-Bridge requiring
the use of 4 switches.

Load Shedding
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.
Overcurrent protection
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 Breakers (ECB) 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 ECB 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 ECB 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 timedelay 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.
21 CLMD16 User’s Manual Rev. 1.8
___________________________________________________________
Figure 11 - Current vs Time Graph
The nominal current that can flow through an ECB 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 ECB’s in the CLMD16 are configured 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.
Binary Event Monitor
A binary event simply means that there are only two possible outcomes, such as a light switch which is either on or off. The CLMD16 can translate the voltages measured on the eight analog/digital inputs, the resistances monitored on the two resistance inputs, and the current monitored on the current loop 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 binary event monitor. The binary event monitor will translate the input voltage signal from a voltage level to one of three discrete states:
• LOW (Connected to DC-)
• FLOAT (No Connection)
• HIGH (Connection to DC +)
CLMD16
User’s Manual Rev. 1.8 22
CLMD16 User’s Manual __
The voltage levels at which these discrete states are calculated are individually programmable for each of the input channels.
There are eleven binary event monitors in the CLMD16. Each of the eight analog/digital inputs, the two resistive inputs, and the current loop input has an associated binary event monitor.
There are two programmable voltage levels:
• Low Threshold
• High Threshold
The binary event monitor also implements a programmable 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 binary event monitor to behave such that the discrete 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 voltage:
• Low Hysteresis
• High Hysteresis

Each channel of the Binary Event Monitor produces three signals that are available to the Switching
Application:

Binary Event x Float – the Binary Event Monitor for channel x is in the FLOAT state
Binary Event x High

the Binary Event Monitor for channel x is in the HIGH state
Switching Application
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.
Counters
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.
CLMD16
User’s Manual Rev. 1.8 24
CLMD16 User’s Manual
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

Timer Delay
The CLMD16 provides sixteen instances of a timer delay function.
The Timer Delay 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 delay 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
Flash
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.
CLMD16
User’s Manual Rev. 1.8 26
CLMD16 User’s Manual
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
Latches
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

Toggle Latch
The switching application provides sixteen instances of a toggle latch.
Each toggle latch maintains its logic state until the single input signal to the toggle latch 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)

Toggle Mode
Unlike Toggle Latch where the Toggle Switching Element is independent to the CLMD16’s ECB’s, each ECB has a Toggle Mode that can be selected. 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.
Logic
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 threeinput 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
29 CLMD16 User’s Manual Rev. 1.8
___________________________________________________________
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.

Alarm Output
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

Configuring the CLMD16
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.

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
– 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
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.
33 CLMD16 User’s Manual Rev. 1.8
___________________________________________________________
• 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. Please refer to

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 “

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 solidstate 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 32 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:
77 CLMD16 User’s Manual Rev. 1.8
___________________________________________________________
“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 Binary Event 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
