Troubleshooting Guide
Compressor System
Observed Symptom Probable Cause Suggested Fix
Lack of Air Pressure from Compressor
Compressor Not Engaging
Lack of air supply to clutch (for air-clutch systems) Repair air leak or re-establish air supply
No pump engagement
•
Confirm
“THROTTLE READY" light is on. If not,
check wiring for damage or disconnected wire.
•
Confirm pump is engaged.
Lack of Air Pressure from Compressor
Compressor Engaging / No air supply to dis-
charges or insufficient air supply
Electric Auto-Sync switches not in correct position.
Confirm 40 PSI in UNLOAD position (200 CFM
systems) and 50
+
PSI in the RUN position. Smaller
compressors have lower UNLOAD pressures.
Verify when in FIXED/RUN whether pressure re-
flects 145-150 PSI.
Air check valve defective Replace or correct installation
Air trim valves out of adjustment
Refer to “Control Air Circuit Calibration" instruc­
tions on Pages 33 and 34.
