Operating Instructions
Safety Switches TX...
Emergency unlocking
Permits opening of a locked safety guard from
outside the danger area without tools.
Important!
It must be possible to operate emergency
f
unlocking manually from outside the protected
area without tools.
Emergency unlocking must possess a marking in‑
f
dicating that it may be used only in an emergency.
The actuator must not be under tensile stress
f
during manual release.
The unlocking function meets all other require‑
f
ments from EN ISO 14119.
Emergency unlocking meets the requirements of
f
Category B according to EN ISO 13849‑1:2015.
The contacts are opened when emergency
unlocking is actuated. A stop command must be
generated with these contacts.
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 fastening 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.
Changing the actuating direction
A
Figure 1: Changing the actuating direction
1. Unscrew and open switch cover.
2. Remove actuating head from the switch by
turning and refit in the required position (bayo‑
net fastening).
3. Fit locking pins supplied for protection against
twisting.
4. Close the switch cover and screw in position.
5. Cover the unused actuating slot with the en‑
closed slot covers.
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
wire for the connections, pay attention to the
required temperature resistance and the max.
mechanical load!
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 2).
Use of the safety switch as guard locking for
process protection
At least one contact
with the symbol can also be used (for terminal
assignment, see Figure 2).
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 2).
4. Check that the cable entry is sealed.
5. Close the switch cover and screw in place
(tightening torque 1.5 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 area.
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 safety guard several times to
check the function. The function of any manual
releases (except for the mechanical release) must
also be tested.
Electrical function test
1. Switch on operating voltage.
2. Close all safety guards and activate guard
locking.
The machine must not start automatically.
¨ ¨
It must not be possible to open the safety 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 safety guard must remain locked until there
¨ ¨
is no longer any risk of injury (e.g. due to move‑
ments 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 safety guard.
Inspection and service
WARNING
Danger of severe injuries due to the loss of the
safety function.
) for safety
If damage or wear is found, the complete switch
f
and actuator assembly must be replaced. Re‑
placement of individual parts or assemblies is
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:
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
must be used. Contacts
Information: 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 instruc‑
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.
Notes about
The following information applies to devices
with cable entry:
For use and applications as per the requirements of
60/75 °C is to be used.
The following information applies to devices
with plug connector:
For use and applications as per the requirements of
must be used. Connection cables for safety switch‑
es 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 insulation materials which
possess an identical or higher dielectric strength
compared to the other relevant parts of the system.
