Troubleshooting Steps
High Temperature
The temperature of the system is near the maximum operation temperature. The
performance has been reduced to prevent the driver from completely shutting down.
• Check fan operation. Clean the fan and driver housing.
• Reduce pressure, duty cycle, or gun tip size.
• Move the unit to a cooler location.
Low Temperature
• Warm equipment.
• Circuit board cannot read motor temperature sensor. Check if the sensor is
plugged into the correct connector.
Motor Temperature Fault
Motor is running too hot. Allow unit to cool.
• Check fan operation. Clean overspray buildup from the fan and driver housing.
• Reduce pressure, duty cycle, or gun tip size.
• Move the unit to a cooler location.
Board Temperature Fault
The control board is running too hot. Allow the unit to cool.
• Check fan operation. Clean overspray buildup from the fan and driver housing.
• Reduce pressure, duty cycle, or gun tip size.
• Move the unit to a cooler location.
Encoder Calibration Error
• Cycle power and check status indicator (L) to see if the error is still active.
• Calibrate the encoder (this code will blink if calibration is in progress).
Encoder Error
• Cycle power and check the status indicator (L) to see if the error is still active.
• Verify that the encoder cable (D) is connected securely (see Wiring Diagrams,
page 27).
• The encoder may need replacement.
Software Versions Do Not Match
• See your system manual, Related Manuals, page 2. for software token part
number.
• Obtain software update token and follow Software Update Procedure, page 23.
Circuit Board Communication Failure
Cycle power and check status indicator (L) to see if the error is still active.
Internal Circuit Board Hardware Failure
Cycle power and check status indicator (L) to see if the error is still active.
Internal Software Error
Cycle power and check status indicator (L) to see if the error is still active.
See Standby Mode, page 12.
