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 voltage applied at the terminals YR-A2 exceeds the
the value adjusted at the regulator. The output relay switches into
off-position (yellow LED not illuminated) when the signal voltage falls
below the set value by more than the fixed hysteresis.

(potentiometer)
Permanently OFF (0)
The contact of checkback B1-B2 is opened.
The output relay R remains in off-position (yellow LED not illuminated)
independent from the connected signal voltage.
0mA
Relay
Permanently ON (HAND)
The contact of checkback B1-B2 is opened.
When the supply voltage U is applied at terminal A1 the output relay
R switches into on-position (yellow LED illuminated).
Changes of the signal voltage do not influence the state of the output
relay.
