1.3.5.5.4 Test Procedure
Once a microswitch is replaced or a position indicator is installed, perform the test
procedure for dual switches:
1. Connect an Ohmmeter to pin 1 (orange wire, Figure 1-10) and pin S (white wire) of
switch S2 connector, then set the meter to measure resistance (Ohms).
2. With the valve in the open position (air pressure applied), adjust switch S2 (right side)
until the Microswitch closes.
3. Tighten the screws holding switch S2.
4. Actuate the valve five times and ensure that the switch S2 opens and closes and is in the
correct position.
5. Close the valve by removing the air pressure from the valve.
6. Connect the Ohmmeter to pin 2 (blue wire) and pin S (white wire) of the switch S1
connector. The meter should still be set to read resistance (Ohms).
7. With the valve in the closed position (no air pressure), adjust switch S1 (left side) until
the Microswitch closes.
8. Apply air pressure to open the valve. Switch S1 should open. Readjust it if necessary by
tightening the screws.
9. Actuate the valve five times to ensure that the switch opens and closes and is in the
correct position.
10. Place the cover on the position indicator and replace the connector using the
appropriate hardware.
