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.
2.5.4 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.
2.5.5 Switch 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.
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
necessary.
• Check the security of all of the switch connections on the top of the unit and tighten if
necessary.
