Error Indications - Error conditions are indicated by a "HLP" message on the display, or by the blinking of the Red LED on Motor Board PC1. To

view the Red LED, turn Off power source, remove shroud, and turn power source On. The number of blinks in this period indicates the type of er-

ror. If an error condition does not exist on the motor board, the Red LED is on steady.

Communication Error - The communication error occurs 2.5 seconds after a loss of communication between the motor board and the meter

board. The user may continue to weld with this error. The error may be cleared by turning power Off, waiting a minimum of two seconds, and

turning power On.

Trigger Error - The trigger error occurs if the user has fed approximately 35 feet (10.7 meters) of wire without striking an arc. The error may be

cleared by releasing the trigger.

Motor Overload Error - The motor overload error can indicate that the motor has been drawing too much current for too long, To remedy this, re-

duce the wire feed speed or the wire feeder torque load/duty cycle. The error may be cleared by turning power Off, waiting a minimum of two sec-

onds, and turning power On.

Bus Bar Overheat Error - The bus bar overheat error can be caused by the arc drawing too much current for too long or degraded/improper

weld circuit connections. To remedy this, reduce the weld amperage or duty cycle and check/repair/clean the weld cable connections including

the welding gun power pin.

Tach Error - May indicate motor is overloaded. If a tach error occurs, feeder will continue to function. When the trigger is released, a tach error

will be indicated on the front panel, or red LED blinks on Motor Control Board (PC1). The tach error will be cleared when the feeder is retriggered.

If error persists, have feeder serviced. Tach error may also be generated if DIP switch SW1 on Motor Control Board (PC1) is set incorrectly (See

Section 5-12).
