    The CLMD16 handles resistive DC loads like lights or inductive DC loads like pumps and motors as well as capacitive loads. 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.

  • Page 25: Soft Start

    ___________________________________________________________ The breakers in the CLMD16 are configurable so that nuisance tripping is avoided where the start- up current may be more than those experienced in a continuous duty cycle. The system installer / configurator will need to know the current rating of the load, the maximum start-up peak current, and duration allowed for the peak in order to correctly configure the ECB settings.

  • Page 26: Soft Turn On / Off

    CLMD16 User’s Manual WARNING Use of a breaker in a PWM mode (duty cycle less than 100%) for control of inductive loads such as motors and transformers is prohibited, and may damage the CLMD16. Soft Turn On / Off If a breaker is configured as PWM type, Soft Turn On/Off can be enabled. Soft Turn On/Off applies a 1 second ramp for the breaker to ‘ramp’...

  • Page 27: Full Bridge Operation

    ___________________________________________________________ Figure 12 - Paralleled Breakers Connection Recommendation Please note that the maximum current rating when multiple breakers are paralleled is typically, 180% of the single channel rating. (Example: 18A maximum for two 10A breakers in parallel). When two breakers are configured in parallel, the lowest-numbered breaker controls the pair For example, if breakers #1 and #2 are configured to operate in parallel, commands that control breaker #1 will control the state of both paralleled breakers.

  • Page 29: Load Shedding

    ___________________________________________________________ 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.

  • Page 30: Input Monitor

    CLMD16 User’s Manual 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.

  • Page 31: Figure 14 - Input Monitor Hysteresis

    ___________________________________________________________ The input monitor also implements configurable hysteresis values. This is where the state of the input intentionally lags behind the actual input’s value relative to the configured High or Low threshold value that may already be met. The purpose of hysteresis is to allow for a buffer to be applied onto either end of configured High or Low level thresholds.

  • Page 32: Reference Ground

    CLMD16 User’s Manual Reference Ground For maximum accuracy using voltage sensing or resistive inputs (Inputs 1-10), the CLMD16’s reference ground (Pin 12 ‘J3’ connector) must be used as the ground reference for the input where applicable. For example, if a resistance-to-ground tank sender is being applied to resistive inputs (input #9 or 10) the reference ground of the tank sender(s) shall be the supplied CLMD16 reference ground.

Holding the button longer than this will cause the dimming level to cycle from the configured min set point to the configured max set point and then back from the max set point to the min set point and repeat this loop behavior until you release the button.

  • Page 34: Timer

    CLMD16 User’s Manual Timer The CLMD16 provides sixteen instances of a timer function. The Timer function provides the Switching Application the ability to postpone the activation of load output channels upon receiving channel activation commands up to 65,535 seconds for each. This is not to be confused with the Soft Start function as the Timer function does not contribute to the load PWM output.
