Overview of Application

The ML-Series Remote Battery Switch provides high-current carrying and switching under load. The Remote Battery Switch should be installed close to the battery banks to avoid voltage drop.

Install a single pole double throw (SPDT) or single pole single throw (SPST) control switch in a convenient location near other electrical controls or companionway to allow quick access in the event of an emergency (see Illustration on reverse).*

*Although a SPST switch may be used if desired, use of a SPDT switch improves immunity to inadvertent switching if the controls become damp.

CAUTION If the ML-RBS Relay state is changed using the Manual Control Knob to a state that is different than the Remote Switch 2155, the relay state will automatically change to match the Remote Switch state after 10 minutes. The two scenarios where this will occur are shaded in the table above.

Remote LED Indicator embedded in PN 2155 SPDT ON-ON Contura Switch

indicates Remote Battery Switch state or condition as follows:

LED Indication	Remote Battery Switch State or Condition
LED is OFF	Remote Battery Switch is OFF
LED is ON	Remote Battery Switch is ON
LED double blinking ON-OFF	Manual override--check Remote Battery Switch for switch states.
	OR Remote Battery Switch mechanical failure

The remote LED embedded in PN 2155 indicates a closed connection between battery bank and load, or between two battery banks when used as an emergency cross-connect.

Remote Operation. PN 2155 (SPDT, ON-ON) Remote Control Contura Switch in the ON position can either connect the battery bank to the load or combine two battery banks. In the OFF position it can either disconnect a battery bank from a load or isolate two batteries from each other.

To connect battery bank to load, or combine	Set remote switch 2155 to position marked “ON”.
battery banks	Remote LED indicates closed connection.
To disconnect battery bank from load, or	Set remote switch 2155 to position marked “OFF”.
isolate battery banks that are connected
