Introduction - Maretron MPOWER CLMD16 User Manual

CLMD16 User's Manual
Congratulations on your purchase of the Maretron MPower
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.
