Correct use
Precision multiple limit switches are used for posi‑
tioning and controlling machines and in industrial
installations.
Correct use includes observing the relevant require‑
ments for installation and operation, particularly
based on the following standards:
EN 60204‑1
f
EN ISO 12100
f
Incorrect use
Precision multiple limit switches with switching ele‑
ment ES502E (snap‑action switching contacts not
positively driven) must not be used in safety circuits.
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. 3).
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.
Switching states
The detailed switching states for your switch can
be found in Fig. 1. All available switching elements
are described there.
Mounting
NOTICE
Device damage due to improper mounting and
unsuitable ambient conditions.
Mounting must be performed only by authorized
f
personnel.
Precision multiple limit switches and actuators
f
must not be used as an end stop.
Protect the precision multiple limit switch against
f
damage.
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.
www
Protection against environmental
www
effects
Safety venting valves are used to equalize the
www
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 type label during painting work!
Electrical connection
NOTICE
Electrical connection must be performed only by
f
authorized personnel.
When choosing the insulation material and
f
wire for the connections, pay attention to the
over‑temperature in the housing (depending on
the operating conditions)!
Strip the insulation from the ends of the individual
f
wires over a length of 6
contact.
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
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
Check correct function sequence.
f
Inspection and service
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.
f
Info: The year of manufacture can be seen in the
bottom, right corner of the type label.
