Solenoid interlock
EN
Emergency release
(Mounting and actuation only outside of the safety guard)
The emergency release should only be used in an
emergency. The solenoid interlock should be installed and/
or protected so that an inadvertent opening of the interlock
by an emergency release can be prevented. The emergency
release must be clearly labelled that it should only be used
in an emergency. The label can be used that was included in
the delivery.
To realise an emergency release, turn the orange lever by 180° in the
direction shown by the arrow until it hits the end stop. In this position,
the safety guard can be opened. The lever is latched and cannot be
turned back. To cancel the blocking condition, the central mounting
screw must be loosened to such extent that the lever can be turned
back into its original position. Return the lever to its original position and
firmly retighten the screw.
Emergency exit
(Fitting and actuation only from within the hazardous area)
To realise an emergency exit, turn the orange lever by 180° in the
direction shown by the arrow until it hits the end stop. In this position,
the safety guard can be opened. The blocked position is cancelled by
turning the lever in the opposite direction. In unlocked position, the
safety guard is protected against unintentional closing.
Emergency release (N)
Emergency exit (T)
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.

2.6 Safety classification of the guard locking function
If the device is used as an interlock for personal safety, a safety
classification of the guard locking function is required.
When classifying the guard locking function, a distinction must be
made between monitoring of the interlocking function and control of the
release function.
The following classification of the release function is based on the
principle of isolating the supply of power to the solenoid.
The safety classification for the release function only applies
to devices with monitored interlock function, in power to
unlock version and with solenoid supply from 24 VDC (AUX)
(see ordering code).
By reliably isolating the power externally, it can be assumed that no
errors can occur with regard to actuation of the release function. In that
case, the device does not contribute towards the failure probability of
the release function.
The level of safety of the release function relies, therefore, exclusively
on reliable external deactivation of the power.
