8.3 Function Test
The safety function test is required to ensure correct operation. The entire
safety circuit must be tested for full functionality.
Tests must be performed at the following times:
•
After installation
•
In regular intervals, or at least once a year.
If the function test results in an invalid machine status, the error must be found and
corrected before the safety function is retested. If the error reoccurs during the func-
tion test, the machine can no longer be operated.
Failure to follow the above safety measures can lead to severe injuries and damage.
