Operating Instructions
Precision Multiple Limit Switches GS...C1806 12 mm
Correct use
Precision multiple limit switches series GS are
interlocking devices without guard locking (type 1).
The actuator is uncoded (e.g. dog). In combination
with a movable guard and the machine control, this
safety component prevents dangerous machine
functions from occurring while the guard is open. A
stop command is triggered if the guard is opened
during the dangerous machine function.
For general applications, snap-action switching ele-
ments ES502E are used. For use as safety switches,
only the switching elements ES508E with positively
driven contacts are allowed.
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.
Devices from this series can be used as safe position
encoders.
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
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 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 13849-2.
If the simplified method according to section 6.3
f
of EN ISO 13849-1:2015 is used for determining
the Performance Level (PL), the PL might be re-
duced if several devices are connected in series.
Logical series connection of safe contacts is
f
possible up to PL d in certain circumstances.
More information about this is available in
ISO TR 24119.
If a product data sheet is included with the prod-
f
uct, the 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.
Mounting, electrical connection and setup only
f
by authorized personnel possessing special
knowledge about handling safety components.
Function
Precision multiple limit switches are used for posi-
tioning and control applications in mechanical and
systems engineering.
The switching elements are actuated by means of
plungers. Different plunger types and trip dogs are
used depending on the application (operating point
accuracy and approach speed) (see Fig. 4).
In general applications, the plunger is actuated by
trip dogs according to DIN 69639 that are mounted
with an interference fit in trip rails in accordance
with DIN 69638.
The switching contacts are actuated when the actu-
ating element is moved from the free position to the
end position. The safety contacts
opened in this process (see Fig. 1).
Switching states
The detailed switching states for your switch can
be found in Fig. 1. All available switching elements
are described there.
Actuating element in free position
The safety contacts are closed.
Actuating element in end position
The safety contacts are open.
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.
It is imperative that dimension
f
from switch reference surface to trip dogs, see
Fig. 3) is maintained in safety circuits to ensure
safe contact opening.
Protect the switch against damage.
f
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.
Protection against environmental
effects
Safety venting valves are used to equalize the
pressure to protect against the pumping action of
the plunger. They must not be sealed with paint.
Mask plunger, plunger guide, safety venting valves
f
and rating plate during painting work!

Electrical connection

WARNING
Loss of the safety function due to incorrect
connection.
Use only safe contacts ( ) for safety functions.
f
Strip the insulation from the ends of the individual
f
wires over a length of 6 mm to ensure a safe
±1
contact.
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. 1).
4
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 (for terminal
assignment, see Fig. 1; for tightening torque
values, see technical data).
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
are positively
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 actuating element must move easily. Close the
guard several times to check the function.
Electrical function test
1. Switch on operating voltage.
2. Close all guards.
The machine must not start automatically.
¨
3. Start the machine function.
4. Open the guard.
The machine must switch off and it must not be
¨
possible to start it as long as the guard is open.
Repeat steps 2 - 4 for each guard.

WARNING
Danger of severe injuries due to the loss of the
safety function.
In safety circuits, the entire switch must be re-
f
placed in case of damage or wear. Replacement
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
precise adjustment of trip dogs in relation to
f
multiple limit switch
damage, heavy contamination, dirt and wear
f
sealing of cable entry
f
loose cable connections or plug connectors.
