702 Pump servo fault
The solenoid resistance was not detected or incorrect
when the device was not triggered. When the solenoid is
not energized, the resistance of the solenoid is checked by
the system. These faults are generated if no resistance is
detected, or the correct resistance is not detected. Check the
proportional valve wiring connections. Check the solenoid
operation. Replace the valve if the solenoid is bad.
705 Powder low PWM
Pump air flow less than commanded value.
Check for obstruction in pump air flow control valve. Clean
valve as described in pump manifold manual.
706 Pattern low PWM
Pattern air flow less than commanded value.
Check for obstruction in pattern air flow control valve. Clean
valve as described in pump manifold manual.
707 Powder high PWM
Powder air flow more than commanded value.
Check output of flow regulator (center regulator in pump
panel) − should be 85 psi. Check for kinked or blocked
powder delivery tubing. Check for blocked pump flow air servo
valve.
708 Pattern high PWM
Pattern air flow more than commanded value.
Check output of flow regulator (center regulator in pump
panel) − should be 85 psi. Check for kinked or blocked
powder delivery tubing. Check for blocked pattern flow air
servo valve.
