The following error messages are shown on the displays to indicate specific errors. Explanations are in the text below:
TRIG ERR 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.
JOG ERR 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.
PURG ERR 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.
COOL ERR 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.
