Only if the information described in this operating
instructions manual are realised correctly, the safety
function and therefore the compliance with the
Machinery Directive is maintained.
2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond
to the standard version.
2.3 Purpose
The solenoid interlock has been designed to prevent in conjunction
with the control part of a machine, movable safety guards from being
opened before hazardous conditions have been eliminated.
Interlocks with power to lock principle may only be used in
special cases after a thorough evaluation of the accident risk,
since the safety guard can be opened immediately on failure
of the power supply or upon activation of the main switch.
The safety switchgears are classified according to
ISO 14119 as type 2 interlocking devices.
Manual release
(for set-up, maintenance, etc.)
Manual release is realised by turning the triangular key by 180° (M5
triangular key available as accessory), so that the locking bolt is pulled
into the unlocking position. Please ensure that jamming by external
influence on the actuator is avoided. The normal locking function is
only restored after the triangular key has been returned to its original
position. After being put into operation, the manual release must be
secured by installing the plastic cover, which is included in delivery.
Lateral manual release Manual release on the cover side
or on the rear side
(ordering suffix -ED/-EU)
Triangular key TK-M5 (101100887) available as accessory.
Emergency release (ordering suffix -N)
(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 activate the emergency release in case of an emergency, the orange
lever must be turned to the stop in the direction marked by the arrow.
In this position, the safety guard can be opened. The lever is latched
and cannot be returned to its original position. 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. The screw
must then be re-tightened.
Emergency exit
(Fitting and actuation only from within the hazardous area)
To activate the emergency exit of the T version in case of an
emergency, the orange lever must be turned to the stop in direction
marked by the arrow. The emergency exit function of the TD and TU
versions is activated by pressing the red pushbutton.
In this position, the safety guard can be opened. The blocking condition
is cancelled by turning the lever in opposite direction or by pulling back
the pushbutton. In unlocked position, the safety guard is protected
against unintentional closing.

If multiple safety components are wired in series, the Performance
Level to ISO 13849-1 will be reduced due to the restricted error
detection under certain circumstances.
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 classification of the release function is only valid for
devices with monitored guard locking function and in the
power to unlock version (see ordering code).
By reliably isolating the power externally, it can be assumed that no
errors can occur with regard to the locking device of the interlock.
In that case, the locking device of the interlock 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.

Fault exclusion with regard to wiring routing must be

If for a certain application the power to unlock version
of a solenoid interlock cannot be used, for this exception
an interlock with power to lock can be used if additional
safety measure need to be realised that have an equivalent
safety level.

3. Mounting
3.1 General mounting instructions
Three mounting holes are provided for fixing the enclosure. The
solenoid interlock is double insulated. The use of an earth wire is not
authorised. The solenoid interlock must not be used as an end stop.
Any mounting position. The mounting position however must be chosen
so that the ingress of dirt and soiling in the used opening is avoided.
Unused actuator openings must be sealed with slot sealing plugs.
The actuator must be permanently fitted to the safety guards
and protected against displacement by suitable measures
(tamperproof screws, gluing, drilling of the screw heads).
Please observe the relevant requirements of the standards
ISO 12100, ISO 14119 and ISO 14120.

4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
If the risk analysis indicates the use of a monitored interlock
they are to be connected in the safety circuit with the
contacts indicated with the symbol .
Appropriate cable glands with a suitable degree of protection are to
be used. Remove the thin walls of the mounting holes by inserting the
cable entry.
Puncturing the wall of the holes with auxiliary tools
(e.g. screwdriver) can cause damage.

The following conditions must be previously checked and met:
1. Fitting of the solenoid interlock and the actuator
2. Check the integrity of the cable entry and connections
3. Check the switch enclosure for damage
5.2 Maintenance
A regular visual inspection and functional test, including the following
steps, is recommended:
1. Check for tight installation of the actuator and the switch
2. Remove particles of dust and soiling
3. Check cable entry and connections
Adequate measures must be taken to ensure protection
against tampering either to prevent tampering of the safety
guard, for instance by means of replacement actuators.
Damaged or defective components must be replaced.
6. Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
