Configurable muting functions
6.8 Override
O
verride is a manual triggering of muting after an error in the muting conditions. By means
of the brief simulation of a valid muting condition, you can mute the protective device
(muting) and then move the system clear and establish an error-free state.
Override can be realised using an external circuit or using the integrated override function.
6.8.1 Override realised using an external circuit
An additional key-operated switch connects the relay K1/K2 directly to 24 V. In this way
you overwrite the outputs OSSD1 and OSSD2.
WARNING
Please pay attention to the following notes on integration!
 The key-operated switch must have a positive-action resetting device and two switching
contacts for K1 and K2.
 Override is only to be effective using a key-operated switch in the manual mode of the
machine or plant controller.
 The control switch for override (key-operated switch) and the control switch for the
restart interlock must not be identical.
 Always fit the key-operated switch so that the entire hazardous area can be seen.
 The key-operated switch and its integration must comply with EN ISO 12100 and
EN 60204E1.
