tions.
Check the device for correct function after installa-
tion and after every fault.
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.
