Operation & Adjustment
Adjusting the Set Point
• Do NOT attempt to adjust the factory setting of the switch.
Breaking the seal affects the switches ability to act as a
differential switch.
Maintenance & Testing
Annually check the switch for proper operation
Set Point Calibration
1. Connect a meter capable of reading +/- 0.1 ohms to the NC
and COM contacts.
2. Measure the resistance across the NC and COM contacts.
If the resistance is more than 1.0 ohm, the switch switch
should be replaced, since this indicates that the switch
contacts are starting to either corrode or carbonizing.

• The NC contact of the AA...A1 breaks when pressure rises
above the set point. It makes automatically when pressure
falls below set point.
3. Apply pressure to the + air pressure connection, and
confirm that the NC contact breaks when pressure rises
above the set point and that the NO contact makes. The
NC contact will make automatically when pressure falls
below the set point pressure.
4. Connect a meter capable or reading +/- 0.1 ohms to the NO
and COM contacts.
5. Measure the resistance across the NO and COM contacts.
