2.3 Purpose
The TZM... / TZF solenoid interlock has been designed to prevent
movable safety guards in conjunction with the control part of a
machine from being opened before hazardous conditions have been
eliminated.
Solenoid interlocks with power to lock principle may only
be used in special cases after a thorough evaluation of
the risk of accident, 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 TZF..S (for set-up, maintenance, etc.)
The manual release is realised by turning the triangular key (included
in delivery) to the right (1), so that the locking bolt is pulled into the
release position. The normal locking function is only restored after the
triangular key has been returned to its original position (2). The manual
release must be sealed after being put into operation (e.g. sealant etc.)
to prevent its utilisation during operation. The manual release must not
be actuated when loaded by the safety guard.
2
Emergency release TZFN
(mounting only on the outside of the safety guard)
To realise an emergency release, the release button (1) must be pulled.
The release button latches. In this position, the safety guard can be
opened. To neutralise the blocked condition, use the triangular key (2)
(included in delivery) to turn the triangular screw to the left until the
release button returns to its original position. The released condition
may only be cancelled by an authorised person. The emergency
release must not be used when the machinery/plant is in operation.
The releases …N, …NE and …NEM mentioned in the order
code below 2.1, are not compliant with the test principle
GS-ET-19. These versions as well as the .CHI, 4Ö and .2MOE
version are not included in the prototype test of the IFA.
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.

Emergency release TZF.NN
(mounting only on the outside of the safety guard)
To realise an emergency release, the release button (1) must be pulled.
In this position, the safety guard can be opened. The release button
latches. To neutralise the blocked condition, the cover of the enclosure
(2) must be opened. The power supply of the machinery/plant must be
switched off prior to opening the cover. Unscrew the blanking plug (3)
and use a screwdriver to push the blocking lever (4) until the release
button returns to its original position. Re-tighten the blanking plug and
put back the cover of the enclosure (tightening torque for the screw 0.8
Nm). The released condition may only be cancelled by an authorised
person. The emergency release must not be used when the machinery/
plant is in operation.

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.
Manual release TZF...NE / TZF...NEM
(concealed mounting only)
To realise an emergency release, the release button (1) must be pulled.
The release button latches. In this position, the safety guard can be
opened. To neutralise the blocked condition, push the release button
once more (2). The release operation and cancelling the released
condition may only be realised by an authorised person. The manual
release must not be used when the machinery/plant is in operation.

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 components however must be mounted
so that the opening of the actuating head is protected against the
penetration of dirt (e.g. sand, dust, chips). In case of painting activities,
the components must be covered.
In all ...CHI versions, the factory set actuating direction must
not be changed. If the actuating direction of these versions is
modified, the holding force F no longer is guaranteed.
If another actuating direction is desired, the four screws of the actuating
head must be loosened. Turn the actuating head in the desired direction
and retighten the screws (tightening torque 0.5 Nm). The default screws
installed in the actuating head can be replaced with the supplied
tamperproof screws.
For power-to-unlock devices (TZF...), the actuator must
be inserted when the actuating head is turned. Any
non-observance of this prescription could result in the
components being damaged.
The safety component and the actuator must be permanently
fitted to the safety guards and protected against displacement
by suitable measures (tamperproof screws, gluing, drilling,
pinning).

Components with LED indication only for 24VDC. The
monitoring contacts of the LED versions are not potentialfree. In combination with these devices, only sequential
circuits can be used, in which both channels are controlled
with positive potential.
For the cable entry, suitable cable glands with an appropriate degree of
protection must be used.
After wiring, the wiring compartment must be cleaned (i.e. remove
excess cables etc.). The fixing screws of the wiring compartment cover
must be tightened with 0.8 Nm tightening torque.

5.1 Functional testing
The safety function of the safety components must be tested.
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.
6.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
