This switch is designed to prevent engine from starting
in a low oil or no oil condition. Oil Sentry
™
may not shut
down a running engine before damage occurs. In some
applications this switch may activate a warning signal.
Read your equipment manuals for more information.
Oil Sentry
™
pressure switch is installed in closure plate
pressure port. On engines not equipped with Oil Sentry
™
installation hole is sealed with a 1/8-27 N.P.T.F. pipe

®
(Loctite
®
PST
®
592™
Thread Sealant or equivalent) to threads of switch.
2. Install switch into tapped hole in closure plate.

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.
