Note that Off should be set for scheme switch [ARC-EN], when the ARC function isnot required.If it is required that the ARC function be removed from service by the operation of anexternal signal, the PLC connection point ‘ARC-OFF’ is provided so that the user can introducean ‘Off” signal. One more external signal can place the ARC function in service using the PLCconnection point ‘ARC-ON’. For example, the user may wish to select ‘On’ or ‘Off’ by pressingbuttons mounted on a relay/control panel, using these PLC connection points. Note that eitherof the signals introduced at the PLC connection points overrides the selection made by thescheme switch [ARC-EN].
