4. Press and release the actuator. Does the
actuator return freely?
Y N
The contact block is faulty and should be re-
placed.
Normally Open Contact
5. Check resistance between contact screws.
Is resistance infinite?
Y N
The contact block is faulty and should be re-
placed.
6. Press the actuator and check resistance be-
tween contact screws. Is resistance less
than 2 Ohms?
Y N
The contact block is faulty and should be re-
placed.
7. The contact block is good.
8. Re-install switch.
Normally Closed contact
9. Check the resistance between contact
screws. Is resistance less than 2 Ohms?
