The following error messages are shown on the

upper and lower displays to indicate specific errors.

Explanations are in the text below:

error.

LED3-Related Error Indications

Error conditions are indicated by LED3 on

PC1. To view LED3, turn Off unit, remove

wrapper, and turn unit On. LED3 is most easily

observed from the left side of the unit.

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-

Front panel is shown removed for purpose of

quence appears as continous blinking.

1 blink = Communication Error

2 blinks = Trigger Error

3 blinks = Tach Error

4 blinks (Continous)= Motor Error

ERR COM1

• The communication error occurs 2.5 sec-

onds after a loss of communication between

the motor and front panel boards. The user

may continue to weld with this error. The er-

ror may be cleared by resetting the unit (see

Section 6-11).

ERR TRG1

• The trigger error occurs if the user has the

trigger held for more than two minutes with-

out striking an arc, 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.

ERR TCH1

• 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.

ERR MTR1

• The motor error indicates that the motor

has been drawing too much current for too

long. To remedy this, reduce the wire feed

speed or the wire feeder torque load/duty

cycle.

Motor Control Board PC1

LED3

DIP Switch S1

There is a two-position DIP

switch S1 located on motor

control board PC1. These

switches are factory-set in the

off position and must remain in

that position for the unit to op-

erate correctly.
