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 ENISO14119:2013, 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 monitoring output OL is switched off; OD can assume an undened state. Open the guard
and close it again after resetting the auxiliary release. The device will then operate normally
again.
7.1.1. Actuating auxiliary release
1. Remove seal label or make a hole.
2. Using a screwdriver, turn the auxiliary release to in the direction of the arrow.
¨ Guard locking is released.
Important!
Ì The actuator must not be under tensile stress during manual release.
Ì Reset the auxiliary release and cover it with a new seal label after use.
Ì Loss of the release function due to mounting errors or damage during mounting.
Ì Check the release function every time after mounting.
Ì After manual release, the solenoid must be energized briey to re-establish the dened state.
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
ENISO14119:2013, 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 specic application. A hazard assessment is required for this purpose. It may
be necessary to take specications 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-
lease function every time after mounting.
Ì Please observe the notes on any enclosed data sheets.
