MODULATE CONTROL VALVE ADJUSTMENT

Ensure that the compressor is isolated from the compressed air system by closing the isolation valve and venting pressure from the drip leg.

Ensure that the main power disconnect switch is locked open and tagged.

1.Put the compressor in the MODULATION mode by placing control selector switch SS in the “MODULATION” position. (Non–(Intellisys models).

2.Remove 1/4” plastic plug from the tee (18) in the regulator valve. Connect a pressure gauge to this port.

3.Loosen the adjustment screw locknut and back out adjusting screw

3turns. See Figure 2

4.Put the main power disconnect switch in the ON position.

5.Open the isolation valve and start the compressor.

6.Adjust the isolation valve to bring the discharge air pressure to the rated discharge pressure (100, 125, 140, or 200 psig).

7.While maintaining the rated discharge pressure, turn the adjustment screw on the modulation valve (see Figure 2) so that the test pressure gauge reads:

30 psig for modulate 60% cfm.

Tighten the adjustment screw locknut.

8.Press UNLOADED STOP. Wait for sump pressure to go 0 psig. Close the isolation valve or vent off all system air.

9.Put the compressor in the desired control mode.

10.Remove the test pressure gauge and replace 1/4” plastic plug.
