Ì
All release functions latch when the device is electrically isolated.
Ì
Guard locking remains released when the release function is reset.
Some situations require the guard locking to be released manually (e.g. malfunctions or an emergency). A function test must
be performed after release.
More information on this topic can be found in the standard EN ISO 14119:2013, section 5.7.5.1. The device can feature
the following release functions:
7.1.
Auxiliary release
In the event of malfunctions, the guard locking can be released with the auxiliary release irre-
spective of the state of the solenoid.
The safety outputs are switched off when the auxiliary release is actuated. Use the safety outputs
to generate a stop command.
The guard locking signal OL is switched off; the door position signal OD can assume an unde-
fined state. Open the guard and close it again after resetting the auxiliary release. The device
will then operate normally again.
