LED3-Related Error Indications

Error conditions are indicated by LED3 on PC1, PC101, and LED4 on PC70. To view LED3, 4 turn Off unit, remove wrapper, and turn unit On.

The LED blinks in a 2.5 second cycle. The number of blinks in this period indicates the type of error.

The priority of the errors is related to the num- ber of blinks indicating the error. The more blinks, the more severe the error (motor error is top priority). A higher priority error overrides a lower one (if a motor error and a communica- tion error existed, the light would blink four times for the motor error).

Since blink On time and blink Off time are equal in a four-blink cycle, the four−blink se- quence appears as a constant blink.

1 blink = Communication Error

2 blinks = Trigger Error

3 blinks = Tach Error

4 blinks = Motor Error

•The communication error occurs 2.5 sec- onds after a loss of communication between the motor and the Front Panel board or Dual board. The user may continue to weld with this error.

•The trigger error occurs if the user has the trigger held for more than two minutes with- out striking an arc (providing current over- ride is not enabled), or if the user holds the trigger past the postflow phase in a timed weld. This error also occurs if the trigger is held when the feeder is powered up. The er- ror may be cleared by releasing the trigger.

•The tach error occurs 2 seconds after the loss of tachometer feedback. The user may continue to weld with this error. The motor speed is regulated through the monitoring of voltage and current.

•The motor error indicates that the motor has been drawing too much current for too long.
