Correct use
Safety switches series GP are interlocking devices
without guard locking (type 2). The actuator has
a low coding level. In combination with a movable
guard and the machine control, this safety compo-
nent prevents dangerous machine functions from
occurring while the guard is open. A stop command
is triggered if the guard is opened during the dan-
gerous machine function.
This means:
Starting commands that cause a dangerous ma-
f
chine function must become active only when the
guard is closed.
Opening the guard triggers a stop command.
f
Closing a guard must not cause automatic starting
f
of a dangerous machine function. A separate start
command must be issued. For exceptions, refer to
EN ISO 12100 or relevant C-standards.
Before the device is used, a risk assessment must
be performed on the machine, e.g. in accordance
with the following standards:
EN ISO 13849-1
f
EN ISO 12100
f
EN IEC 62061
f
Correct use includes observing the relevant require-
ments for installation and operation, particularly
based on the following standards:
EN ISO 13849-1
f
EN ISO 14119
f
EN IEC 60204-1
f
Important!
The user is responsible for the proper integration
f
of the device into a safe overall system. For this
purpose, the overall system must be validated,
e.g. in accordance with EN ISO 13849-1.
If the simplified method according to section
f
6.2.3 of EN ISO 13849-1:2023 is used for
determining the Performance Level (PL), the
PL might be reduced if several devices are
connected in series.
The logical series connection of safe contacts
f
may limit the achievable Performance Level (PL)
in certain circumstances. More information about
this is available in ISO TR 24119.
If a data sheet is included with the product, the
f
information on the data sheet applies in case of
discrepancies with the operating instructions.
Safety precautions
WARNING
Danger to life due to improper installation or due
to bypassing (tampering). Safety components
perform a personnel protection function.
Safety components must not be bypassed,
f
turned away, removed or otherwise rendered
ineffective. On this topic pay attention in partic-
ular to the measures for reducing the possibility
of bypassing according to EN ISO 14119:2013,
section 7.
The switching operation must be triggered only
f
by actuators designated for this purpose.
www
Prevent bypassing by means of replacement
f
actuators. For this purpose, restrict access to
www
actuators and to keys for releases, for example.
Mounting, electrical connection and setup only
f
www
by authorized personnel possessing special
knowledge about handling safety components.
Function
The safety switch monitors the position of movable
guards. The switching contacts are actuated on the
insertion/removal of the actuator.
Switching states
The detailed switching states for your switch can
be found in Fig. 3. All available switching elements
are described there.
Guard open
The safety contacts
are open.
Guard closed
The safety contacts
are closed.
Selection of the actuator
NOTICE
Damage to the device due to unsuitable actuator.
Make sure to select the correct actuator (see
f
table in Fig. 4).
Increased overtravel of the actuator possible only
f
with a horizontal approach direction.
Additionally pay attention to the door radius and
f
the mounting options (see Fig. 5).
The following versions are available:
Standard actuator with standard overtravel.
f
Overtravel actuator with increased overtravel.
f
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
A
Fig. 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 (
) for safety functions.
f
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 individual
f
wires over a length of 6
mm to ensure a safe
±1
contact.
Fig. 2: Opening the safety switch
Use of the safety switch as an interlocking
device for personnel protection
At least one contact
must be used. This signals
the position of the guard (for terminal assignment,
see Fig. 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 terminals with 0.5 Nm (for
terminal assignment, see Fig. 3).
4. Check that the cable entry is sealed.
5. Close the switch cover and screw in place
(tightening torque 0.8 Nm).
