Indicates a trigger error. A trigger error occurs if the user has the trigger held for more than two
minutes without striking an arc. This error also occurs if the trigger is held when the feeder is powered
up. The error may be cleared by releasing the trigger.
Indicates a jog switch error. A jog switch error occurs if the user has the jog switch held for more than
two minutes. This error also occurs if the jog switch is held when the feeder is powered up. The error
may be cleared by releasing the jog switch.
Indicates a purge switch error. A purge switch error occurs if the user has the purge switch held for
more than one minute. This error also occurs if the purge switch is held when the feeder is powered
up. The error may be cleared by releasing the purge switch.
Indicates a water flow switch error. A water flow switch error occurs if no water flow is detected while
the trigger is pressed. Jog and purge switches will behave normally even if no water flow is detected.
Dip switch 2 on the motor control pcb must be set to enable this error. The error is cleared when wa-
ter flow is detected or when the error is disabled.
Indicates a power on self diagnostic test error. The number provides information regarding the error.
If this error occurs, contact a Factory Authorized Service Agent.
Indicates a serial communication error. A communication error occurs 2 seconds after a loss of com-
munication between the motor control pcb and the front panel pcb.
Indicates a gun calibration wire restriction error. This error occurs if the detected wire speed during a
calibration is too slow. This error will not prevent the feeder from operating, but wire speed accuracy
may be compromised. See section 8-4.
Indicates a gun calibration wire slip error. This error occurs if the detected wire speed during a calibra-
tion is too fast. This error will not prevent the feeder from operating, but wire speed accuracy may be
compromised. See section 8-4.
Indicates a motor control pcb error. If this error occurs, contact a Factory Authorized Service Agent.
Indicates a front panel pcb error. If this error occurs, contact a Factory Authorized Service Agent.
