Operating Instructions
Safety Switches NP...
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.
Electrical function test
1. Switch on operating voltage.
2. Close all safety guards.
¨
¨
The machine must not start automatically.
3. Start the machine function.
4. Open the safety guard.
¨
¨
The machine must switch off and it must not be
possible to start it as long as the safety guard
is open.
Repeat steps 2 - 4 for each safety guard.
Inspection and service
WARNING
Danger of severe injuries due to the loss of the
safety function.
f
If damage or wear is found, the complete switch
and actuator assembly must be replaced. Re-
placement of individual parts or assemblies is
not permitted.
f
Check the device for proper function at regular
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:
f
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.
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
, a copper wire for the temperature range
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
, a class 2 power supply according to UL1310
must be used. Connection cables for safety 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 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.
