Reset
The control unit works without a reset function. If the protective device stops be-
ing actuated, the output signal switching device of the control unit automatically
switches from the OFF state to the ON state after a delay t

starting lockout, the machine would start up again immediately.
Manual reset
The control unit works with a reset function. If the protective device stops being
actuated, the output signal switching devices of the control unit remain in the
OFF state. This prevents the machine from restarting. Only a “Reset” command will
change the state from OFF to ON.

tion:
•
Disconnect from the power supply all devices and live parts that are located in
the immediate vicinity.
•
Secure them to prevent them being switched back on.
•
Check that they are de-energised.
1. Fix the control unit in any position on a 35°mm mounting rail acc. to
IEC 60715.
