Testing
Compressed air, a pressure regulator, pressure gauge,
and a continuity tester are required to test switch.
1. Connect continuity tester across blade terminal and
metal case of switch. With 0 psi pressure applied to
switch, tester should indicate continuity (switch
closed).
2. Gradually increase pressure to switch. As pressure
increases through range of 7-11 psi tester should
indicate a change to no continuity (switch open).
Switch should remain open as pressure is increased
to 90 psi maximum.
3. Gradually decrease pressure through range of 7-11
psi. Tester should indicate a change to continuity
(switch closed) down to 0 psi.
4. Replace switch if it does not operate as specifi ed.
