Operating Instructions Safety Switches TX...
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:
correct switching function
secure mounting of components
dirt and wear
sealing of cable entry
loose cable connections or plug connectors.
Safety switches must be exchanged completely after
1 million switching operations.
Note: The year of manufacture can be seen in the
bottom, right corner of the rating plate.
Exclusion of Liability under the Following
Conditions:
incorrect use
non-compliance with safety regulations
installation and electrical connection not performed
by authorized personnel
failure to perform functional checks.

The solenoid operating voltage, the LED operating
voltage and the control voltage (only TX3...024) for
the interlocking solenoid must comply with the infor-
mation on the rating plate (e.g. U
B
= AC/DC 24 V).
Solenoid operating voltage and control voltage can be
jumpered if a current of 2 A can be supplied when the
solenoid is switched on for T
IMP
= 250 ms.
Version TX...M/N (cable entry)
Unscrew locking screw for the required insertion
opening.
Fit the cable gland with the appropriate degree of
protection.
Important: To achieve the specified degree of pro-
tection, use a cable gland from EUCHNER (order. no.
110 132, 110 133 or 110 134).
For pin assignment see Figure 4.
Tighten the screws with a torque of 0.5 Nm.
Check that the cable entry is sealed.
Close the cover and screw in position.
Version TX..RC18/BH12 (plug connector)
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:
Mechanical function test
The actuator must slide easily into the actuating
head. Close the safety guard several times to check
the function.
Electrical function test
1. Switch on operating voltage.
2. Close all safety guards.
In the case of guard locking by solenoid force,
Æ activate guard locking.
The machine must not start automatically.
It must not be possible to open the safety guard.
3. Enable operation in the control system.
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.
The safety guard must remain locked until there is
no longer any risk of injury.
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.
