Operating Instructions Safety Switches TP...
f Electrical function test
1. Switch on operating voltage.
2. Close all safety guards.
Guard locking by solenoid force:  Activate
guard locking.
f
The machine must not start automatically.
f
It must not be possible to open the safety guard.
3. Enable operation in the control system.
f
It must not be possible to deactivate the guard
locking as long as operation is enabled.
4. Disable operation in the control system and
deactivate guard locking.
f
The safety guard must remain locked until there is
no longer any risk of injury.
f
It must not be possible to start the machine as long
as the guard locking is deactivated.
Repeat steps 2 - 4 for each safety guard.
Inspection and Service
If damage or wear is found, the complete switch
and actuator assembly must be replaced.
Replacement of individual parts or assemblies
is not permitted!
No servicing is required, but regular inspection
of the following is necessary to ensure trouble-free
long-term operation:
f
correct switching function
f
secure mounting of components
f
dirt and wear
f
sealing of cable entry
f
loose cable connections or plug connectors.
Note:The year of manufacture can be seen in the
bottom, right corner of the rating plate.
Exclusion of Liability under the Following
Conditions
f
if the unit is not used for its intended purpose
f
non-compliance with safety regulations
f
non-compliance with safety regulations
f
failure to perform functional checks.

Electrical Connection
When choosing the insulation material and wire
for the connections, pay attention to the over-
temperature in the housing (depending on the
operating conditions)!
Only switching contacts marked with the posi-
tively driven NC contact symbol are to be used
for the safety circuit.
For switching elements with four positively driven
NC contacts only the contacts 21-22 and 41-42
are actuated on activating and deactivating the
guard locking. In applications with potentially haz-
ardous states (e.g. overtravelling movements),
contact 21-22 and/or 41-42 must always be
integrated into the safety circuit.
For TP with plug connector:
For use and applications as per the requirements of
, a class 2 power supply or a class 2 transformer
according to UL1310 or UL1585 must be used.
Connection cables for safety switches installed at the
place of use must be separated from all moving and
permanently installed cables and un-insulated active
elements of other parts of the system which operate
at a voltage of over 150 V. A constant clearance of
50.8 mm must be maintained. This does not apply if
the moving cables are equipped with suitable insula-
tion materials which possess an identical or higher
dielectric strength compared to the other relevant
parts of the system.
For TP without plug connector:
For use and applications as per the requirements of
, copper wire 60/75 °C is to be used.
The operating voltage for the interlocking solenoid
must match the value on the rating plate (e.g.
U
S
= AC/DC 24 V).
f Version TP.. (cable entry M20x1.5/PG 13.5/
NPT ½“)
f
Break out the required entry opening.
f
Fit the cable gland with the appropriate degree of
protection.
f
For pin assignment see Figure 3.
f
Tighten the screws with a torque of 0.5 Nm.
f
Check that the cable entry is sealed.
f
Close the cover and screw in position.
f Version TP..SR.. (plug connector)
f
For pin assignment see Figure 3.
Functional Check
Warning! Danger of fatal injury as a result of faults
in installation and functional check.
Before carrying out the functional check, make
sure that there are no persons in the danger
area. Observe the valid accident prevention
regulations.
After installation and any fault, the safety function
must be fully checked. Proceed as follows:
f Mechanical function test
The actuator must slide easily into the actuating
head. Close the safety guard several times to check
the function.
