8.3.1 E001 Shorted Control Cable-Fix Control
Cable and/or Gun
Fatal, meaning you have to power down to continue welding
>> No
Acknowledge, meaning the error will exist as long as the unit
is powered on. (Note, welding can continue while the error
exists)
>> Yes
Description:
The gun drive circuit sensed a current surge of 10A or greater for at
least 10us. When this condition is sensed, the gun drive turns off and
the user interface displays this error. The gun may be retriggered and
the unit does not need to be powered down.
Likely problems or items to check - in order from most likely to least
likely:
1.
A cable short in the combo cable external to the unit
2.
A wiring or switch short in the gun
3.
Internal wiring from the gun driver board to the weld output
board, weld output board to the front panel gun connector
4.
Failure of the gun driver board.
8.3.2 E002 Primary Voltage Dip too Low-
Check Primary Voltage
Fatal, meaning you have to power down to continue welding
>> No
Acknowledge, meaning the error will exist as long as the unit
is powered on. (Note, welding can continue while the error
exists)
>> Yes
Description:
The FACS input board senses the +15VDC gate drive power supply
generated on-board from the 24VDC input. When the gate supply falls
below 13VDC (1ms during a weld, or 20ms while idle), this error will be
displayed and if welding, the weld will stop immediately. +15VDC and
ground is located at U15 pin 3 and TP14, respectively, of FACS output
SMPS board.
