Installation
Auxiliary/Manual Release
Functional Testing
A manual functional electric test must be made:
• After installation
• After any maintenance or change of component
• If the guard is used infrequently
– Less than once a month for SIL 3/PLe
– Less than once a year for SIL 2/PLd
1. Confirm that the guard door is open.
2. Connect the 24V DC power to pin 2 and ground (0V) to pin 7. The
switch conducts a self-testing routine at the end of which the diagnostic
indicator is solid red.
3. Test to confirm that the machine cannot start.
4. Confirm the lock control at pin 3 is set to 0V for PTR and 24V for PTL
types.
5. Test again to confirm that the machine cannot start.
6. Close the guard door and then confirm that the guard is mechanically
locked and the diagnostic indicator is solid green.
7. Test to confirm that the machine can start.
8. Change the lock control at pin 3 to 24V for PTR and 0V for PTL types.
9. Confirm the machine stops, the guard door is mechanically unlocked, and
the machine cannot restart.
The manual release is provided to
allow you to unlock the guard door if
an unforeseen and uncommon
circumstance occurs.
If power is supplied to the switch and
the switch is in its locked state, if you
invoke the auxiliary release, it causes
the switch to enter a fault condition
(blinking red status indicator).
To reset the switch, simply cycle the
power.

ATTENTION:
During the functional test, confirm that there are no persons in
the danger area and that the machine startup does not cause a hazard.
