Test Valve(Typical example) (1) Pressure contactor (2) Setting screw for the pressure contactor (3) Connection for a pressure contactor (4) Connection for a pressure contactor (5) Test port (6) Test valve
Turn the test valve (6) to the isolated position.
Connect an air hose to the quick connect hose fitting / test port (5) .
Apply a pressure that is 50 kPa (7 psi) higher than the specified setting of the contactor (1) to the test port (5) .
Slowly reduce the pressure. Monitor the pressure as the contactor changes states.
If the contactor (1) changes states at the specified setting within 10 kPa (1.5 psi), then the setting is good. Refer to the Testing and Adjusting, "Contactor - Adjust"section of this manual, if the contactor (1) does not change states at the specified setting.
