Operating Instructions
Safety Switch TP...
Auxiliary release
In the event of malfunctions, the guard locking can
be released with the auxiliary release irrespective
of the state of the solenoid.
The contacts
are opened when the auxiliary
release is actuated. A stop command must be
generated with these contacts.
Actuating auxiliary release
1. Unscrew locking screw.
2. Using a screwdriver, turn the auxiliary release
to
in the direction of the arrow.
Guard locking is released.
¨
Important!
The actuator must not be under tensile stress
f
during manual release.
After use, reset the auxiliary release and screw in and
f
seal the locking screw (e.g. with sealing lacquer).
Auxiliary key release/auxiliary
release with triangular wedge
Function as for auxiliary release.
Important!
The actuator must not be under tensile stress
f
during manual release.
Escape release
Permits opening of a locked guard from the danger
zone without tools.
Important!
It must be possible to actuate the escape re-
f
lease manually from inside the protected area
without tools.
It must not be possible to reach the escape
f
release from the outside.
The actuator must not be under tensile stress
f
during manual release.
The escape release meets the requirements of
f
Category B according to EN ISO 13849-1:2015.
The contacts
are opened when the escape
release is actuated. A stop command must be
generated with these contacts.
Emergency release
Permits opening of a locked guard from outside the
danger zone without tools.
Important!
It must be possible to operate the emergency
f
release manually from outside the protected
area without tools.
The emergency release must possess a mark-
f
ing indicating that it may be used only in an
emergency.
The actuator must not be under tensile stress
f
during manual release.
The release function meets all other require-
f
ments from EN ISO 14119.
The emergency release meets the requirements of
f
Category B according to EN ISO 13849-1:2015.
The contacts
are opened when the emergency
release is actuated. A stop command must be
generated with these contacts.
Wire front release (bowden)
Release via a pull wire. Depending on the type of
attachment, the wire front release can be used as
emergency release or escape release.
Important!
The wire front release meets the requirements of
f
Category B according to EN ISO 13849-1:2015.
The correct function depends on the laying of
f
the pull wire and the attachment of the pull
handle, and this is the responsibility of the plant
manufacturer.
The actuator must not be under tensile stress
f
during manual release.
Mounting
NOTICE
Device damage due to improper mounting and
unsuitable ambient conditions
Safety switches and actuators must not be used
f
as an end stop.
Observe EN ISO 14119:2013, sections 5.2 and
f
5.3, for information about mounting the safety
switch and the actuator.
Observe EN  ISO  14119:2013, section 7, for
f
information about reducing the possibilities for
bypassing an interlocking device.
Protect the switch head against damage, as well
f
as penetrating foreign objects such as swarf,
sand and blasting shot, etc.
The specified IP degree of protection is applica-
f
ble only if the housing screws, cable entries and
plug connectors are properly tightened. Observe
the tightening torques.
Changing the actuating direction
Figure 1: Changing the actuating direction
1. Remove the screws from the actuating head.
2. Set the required direction.
3. Tighten the screws with a torque of 0.8 Nm.
4. Cover the unused actuating slot with the en-
closed slot cover.

Electrical connection

WARNING
Loss of the safety function due to incorrect
connection.
Use only safe contacts (
and
f
functions.
When choosing the insulation material and
f
wires for the connections, pay attention to the
required temperature resistance and the max.
mechanical load!
Strip the insulation from the ends of the individ-
f
ual wires over a length of 6
±1
reliable contact.
Use of the safety switch as guard locking for
personnel protection
At least one contact
must be used. It signals
the guard locking state (for terminal assignment,
see Figure 3).
Use of the safety switch as guard locking for
process protection
At least one contact
must be used. Contacts
with the
symbol can also be used (for terminal
assignment, see Figure 3).
The following information applies to devices
with plug connector:
Check that the plug connector is sealed.
f
The following information applies to devices
with cable entry:
1. Use a suitable tool to open the desired inser-
tion opening.
2. Fit the cable gland with the appropriate degree
of protection.
3. Connect and tighten the terminals with 0.5 Nm
(for terminal assignment, see Figure 3).
4. Check that the cable entry is sealed.
5. Close the switch cover and screw in place
(tightening torque 0.8 Nm).

Function test
WARNING
Fatal injury due to faults during the function test.
Before carrying out the function test, make sure
f
that there are no persons in the danger zone.
Observe the valid accident prevention regula-
f
tions.
Check the device for correct function after installa-
tion and after every fault.
Proceed as follows:
Mechanical function test
The actuator must slide easily into the actuating
head. Close the guard several times to check the
function. The function of any manual releases (except
for the auxiliary release) must also be tested.
Electrical function test
1. Switch on operating voltage.
2. Close all guards and activate guard locking.
The machine must not start automatically.
¨
It must not be possible to open the guard.
¨
3. Start the machine function.
It must not be possible to release guard locking
¨
as long as the dangerous machine function is
active.
4. Stop the machine function and release guard
locking.
The guard must remain locked until there is no
¨
longer any risk of injury (e.g. due to movements
with overtravel).
It must not be possible to start the machine
¨
function as long as guard locking is released.
Repeat steps 2 - 4 for each guard.
Inspection and service
WARNING
Danger of severe injuries due to the loss of the
safety function.
If damage or wear is found, the complete switch
f
and actuator assembly must be replaced. Re-
placement of individual parts or assemblies is
) for safety
not permitted.
Check the device for proper function at regular
f
intervals and after every fault. For informa-
tion about possible time intervals, refer to
EN ISO 14119:2013, section 8.2.
Inspection of the following is necessary to ensure
trouble-free long-term operation:
 mm to ensure a
correct switching function
f
secure mounting of all components
f
damage, heavy contamination, dirt and wear
f
sealing of cable entry
f
loose cable connections or plug connectors.
f
Info: The year of manufacture can be seen in the
bottom, right corner of the type label.
Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety regula-
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
