HAR1 Functions Automatic (AUTO): The contact of checkback B1-B2 is closed. When the signal voltage U is applied at terminal A3 the output relay R switches into on-position (yellow LED illuminated). Permanently OFF (0): The contact of checkback B1-B2 is opened. The output relay R remains in off-position independent from the connected signal voltage. Permanently ON (HAND): The contact of checkback B1-B2 is opened.
