7. Manual release
Important!
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
should 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.
Ì
When release monitoring is active, the system enters into a latching fault when the auxiliary
release is actuated. See
Signal sequence incorrect
status (DIA red,
Lock flashes 1 time).
Ì
The safety outputs are switched off when the auxiliary release is actuated.
Guard lock monitoring output/bit OL is switched off; door position monitoring output/bit OD
can assume an undefined state. Open the guard and close it again after resetting the auxiliary
release. The device will then operate normally again.

Ì
Please observe the notes on any enclosed data sheets.
Ì
The auxiliary release must be reset at the control system level, e.g. by means of a plausibili-
ty check (status of the safety outputs does not match the guard locking control signal). See
EN ISO 14119:2013, sec. 5.7.5.4.
Ì
The auxiliary release is not a safety function.
Ì
The machine manufacturer must select and use a suitable release (escape release, emergency
release, etc.) for a specific application. A hazard assessment is required for this purpose. It may
be necessary to take specifications from a product standard into account.
Ì
The correct function must be checked at regular intervals.
Ì
Loss of the release function due to mounting errors or damage during mounting. Check the re-
