OCL1 Functions Automatic (AUTO) The contact of checkback B1-B2 is closed. The output relay R switches into on-position (yellow LED illuminated) when the signal applied at the terminals YR-A2 exceeds the value adjusted at the regulator. The output relay switches into off-position (yellow LED not illuminated) when the signal falls below the set value by more than the fixed hysteresis. 20mA 0mA 20mA 0mA Permanently OFF (0) The contact of checkback B1-B2 is opened.
