Operating instructions

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.
