.4 DIP switch for configuring the operating mode
S1
„ON“: Automatic reset
„OFF“: Fault self-retaining – manual reset (factory setting)
S2
„ON“: AUX1 Mode signal output: RLU
„OFF“: AUX1 Mode signal output: RL (factory setting)
7. Operating modes
7.1 Safety output
Separate or series-connected output of the control circuits (redundant continuation of the switching contacts).
In order to use the two safety relays separately, the bridge between
14
and
23
must be removed.
7.2 Automatic reset
(
S1
= „ON“)
After removing a fault in a sensor circuit or after a voltage failure, the switching unit will automatically release
output again.
Attention:
Automatic restart of mashine! If this setting is used, it has to be ensured that no one
is able to be in the dangerous zone to avoid hazardous situations. The integrator or operator is
responsible for the correct settings of the controller. In no case the manufacturer is liable for
incorrect settings or missuse.
7.3 Fault self-retaining – manual reset
(
S1
= „OFF“)
Following removal a fault of in a sensor circuit, or after a voltage failure, the switching unit will only release
the output(s) again, if the
Z1
and
Z2
contacts, 500 ms after the elimination of the disruption, are closed by
means of a pushbutton. This completely prevents any automatic re-start. A permanent bridging of the
Z1
and
Z2
contacts does not cause an automatic reset.
7.4 Signaling output without any delay (RLU)
(
S2
= „ON“)
In this mode of operation the corresponding signaling
output is activated without delay, if any fault is signaled on
the corresponding channel. The output is always inactive
in the de-energized state of the switching device.
7.5 Signaling output delayed (RL)
(
S2
= „OFF“)
In this operating mode the corresponding signaling output
is activated with a delay of 0.5 seconds and then remains
active for a maximum of 3 seconds, if a fault is signaled.
