Err 0081

Average

The wire drive has exceeded the current rating:

 

motor Over-

ƒ 10 amps for 0.5 seconds or

 

current

ƒ 3.5 amps for 10 seconds.

 

shutdown

Wait 45 seconds for the error to reset.

 

 

Reduce the current load on the motor by:

 

 

ƒ Verifying the electrode slides easily through the

 

 

liner of the gun.

 

 

ƒ Reduce the spindle brake resistance.

 

 

ƒ Reduce the amount of tension in the wire drive

Some inverters and choppers may have spikes on the

output that charge the capacitors inside the LN-15

beyond limits. If this error occurs, lower the OCV of

the power source. It may be likely that a different

power source is required.

Not Used

 

The display board communicates to the feedhead board through the SPI bus. Only thepower supply signals can be monitored during servicing.

The WFS always shows the present WFS.

The voltage display shows the voltage while welding, plus holds the voltage for 5 seconds after the weld. It shows "-- -" when idle. A negative "-" sign will automatically be shown when welding with reverse polarity procedures.

All the LEDs, including those not used, will briefly light on power up. The LED's not used are visible behind the nameplate when lit.

BOOST BOARD

 

The boost board takes the weld voltage

 

and boosts it to 80VDC for the rest of

 

the LN-15. There are two supplies on

 

the boost board, one for the motor and

 

the other for the feedhead board. With

 

two supplies, even if the motor supply

 

should droop because of heavy loads,

 

power to the feed head board is not

 

affected.

 

The rectifier allows the LN-15 to

 

be powered either electrode

positive or electrode negative

 

without any switches for the

 

customer to set.
