7. Manual release
Some situations require the guard locking to be released manually (e.g. malfunctions or an emergency). A function test
should be performed after release.
More information on this topic can be found in the standard ENISO14119:2013, section 5.7.5.1. The device can feature
the following release functions:
7.1. Auxiliary release and auxiliary key release (can be retrotted)
In the event of malfunctions, the guard locking can be released with the auxiliary release irrespective of the state of the
solenoid.
The zero sequence is sent via the ASi bus when the auxiliary release is actuated.
Open the guard and close it again after resetting the auxiliary release. The device will then operate normally again.

Ì After use, reset the auxiliary release and screw in and seal the locking
screw (e.g. with sealing lacquer).
