235.6.3 INPUTS SIGNAL CONFIGURATIONFigure 5.6.3Communication Interface BoxThe Communication Interface Box is shipped from the factory configured to accept +12/24 volt DC input signals, but can be fieldchanged to accept ground input signals. To change the configuration:1. Remove lid from enclosure.2. Locate DIP switches on communication board.3. Slide DIP switch #4 to the OFF position to select GROUND inputs or slide to the ON position to select VOLTAGE inputs.4. Replace lid. Verify rubber seal is clean and undamaged. Verify that no wires are caught between lid and box.VOLTAGEINPUTSGROUNDINPUTS5.6.4 COMMUNICATION INTERFACE BOX WITH AT STOW RELAY (Y4E-COMM)The Communication Interface Box provides feedback for the user that the monitor is in the AT STOWED position. The Interface Boxcontains a circuit board that is equipped with a relay that is energized when the monitor is in use and de-energized when the monitorreaches its final STOW location. The contact rating of the relay is 1 amp @ 30VDC for resistive loads and 0.2 amps @ 30VDC forinductive loads.The AT STOW relay has one Form-C contact (common, normally open, normally closed) that can be used. The figure below shows theterminal blocks available for user wiring.Figure 5.6.4Relay / Terminal LocationAT STOW RELAYUSER TERMINALS
