Mechanical release and mechanical key release
(can be retrofitted)
Important:
Ì The mechanical release is not a safety function.
Ì The machine manufacturer must select and use a suitable release (escape re-
lease, emergency unlocking, etc.) for a specific application. A risk assessment
appraisal is required for this purpose. It may be necessary to take specifications
from a product standard into account.
Ì The mechanical key release must not be used to lock the switch during main-
tenance work to prevent activation of guard locking, for example.
Ì The correct function must be checked at regular intervals.
Ì Loss of the release function due to mounting errors or damage during mounting.
Ì Check the release function every time after mounting.
Ì Loss of the release function due to tension on the actuator. The door must not
be under tension during release.
Ì Please observe the notes on any enclosed data sheets.
The mechanical release can be used to unlock guard locking, irrespective of the
state of the solenoid.
Using mechanical release
1. Unscrew locking screw
2. Using a screwdriver, turn the mechanical release by around 180° in the di-
rection of the arrow
The lift tappet is extended and raises the actuator's guard locking pin over the
edge of the recess. The half-sequence is sent via AS-Interface input bits D0 and
D1 in every bus cycle.
¨ The safety device can be opened
The mechanical release must be returned to its original position and sealed after
use (for example with sealing lacquer).
Using mechanical key release
On devices with mechanical key release (can be retrofitted), simply turn the key to
unlock. For mounting, see the mechanical key release supplement.
