Operating Instructions
Safety Switch SGA...
Mechanical function test
The actuator must slide easily into the actuating
head. 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.
Inspection and service
WARNING
Danger of severe injuries due to the loss of the
safety function.
If damage or wear is found, the complete switch
f
and actuator assembly must be replaced. Re-
placement 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
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.
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
The following information applies to devices
with cable entry:
For use and application as per the requirements
of a copper wire for the temperature range
60/75 °C must be used.
The following information applies to devices
with plug connector:
This device is intended to be used and applied with
a Class 2 power source in accordance with UL1310.
Connecting 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 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.
