Operating Instructions
Position Switch NG…
Correct use
Position switches series NG are used for posi-
tioning and controlling machines and in industrial
installations.
The built-in switching element with snap-action
function has an NO and an NC contact with double
gap and electrically isolated switching bridge (direct
opening travel 2 x 0.6mm).
Correct use includes compliance with the relevant
requirements for installation and operation, in
particular
fEN60204-1
fENISO12100
Incorrect use
Position switches with switching element ES510
(snap-action switching contact not positively driven)
must not be used in safety circuits.
Mounting
Mounting must be performed only by authorized
personnel.
The position switches must not be used as a
mechanical end stop.
The actuator (arm) can be positively mounted to the
actuating shaft.
The square drives on the actuator and actuating
shaft must engage with each other (see Figure 2a).
Continuously adjustable fastening is possible (inter-
ference t, see Figure 2b).
To ensure correct operation, the trip dog must move
the actuator at least 1mm or 5° beyond the operat-
ing point (see Figure 5 Travel diagrams).
Position switches must be attached and, if nec-
essary, protected in such a way that predictable
damage can be avoided.
It must be ensured that position switches are acces-
sible for maintenance and function tests.
Important!
fTo prevent the actuating element from bouncing,
the dog must run out gradually (see Figure 1).

Electrical connection
Electrical connection must be performed only
by authorized personnel.
When choosing the insulation material and
wire for the connections, pay attention to the
over-temperature in the housing (depending on
the operating conditions)!

Inspection and service
No servicing is required.
Inspection of the following is necessary to ensure
trouble-free long-term operation:
fcorrect switching function
fsecure mounting of all components
fdamage, heavy contamination, dirt and wear
fsealing of cable entry
floose cable connections or plug connectors.
Info: 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 regula-
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.
Notes about
For NG2:
For use and applications as per the requirements of
, a class2 power supply or a class2 transform-
er according to UL1310 or UL1585 must be used.
Connection cables for position switches 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 that
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 that possess an
identical or higher dielectric strength compared to
the other relevant parts of the system.
For NG1:
For use and applications as per the requirements
of , copper wire 60/75°C is to be used.
