Troubleshooting
Solution Solution Solution
Verify shaping air 1 (inner) hose is not
cut or split.
Verify shaping air 2 (outer) hose is not
cut or split.
Verify shaping air 1 (inner) hose is not
cut or split.
Verify shaping air 2 (outer) hose is not
cut or split.
• Calibrate the voltage to pressure
regulator. See the System Logic
Controller manual.
• Verify air tubing is connected properly.
• Verify cable connection between
voltage to pressure (V2P) regulator
and connector 6 on the control
module. Retry calibration.
• Replace the V2P regulator.
• Relieve inlet air pressure. Retry
calibration. See System Logic
Controller manual.
• Verify cable connection between
voltage to pressure (V2P) regulator
and connector 6 on the control
module. Retry calibration.
• Replace cable 17K902.
• Replace volltage to pressure regulator
