7-2. Diagnostics (Continued)
WELD WAIT
•
The weld wait error indicates unit was not
ready for a weld sequence. Press Jog/
Purge button to clear error.
MOTR COM
•
The motor communication error indi-
cates motor board lost data communica-
tions. Press Jog/Purge button to clear error.
If condition persists, contact nearest factory
authorized service agent.
PLS WAIT
•
The uim communication error indicates
user interface board lost data
communications. Press Jog/Purge button
to clear error. If condition persists, contact
nearest factory authorized service agent.
LOW WFS
•
The low wire feed speed error indicates
actual wire feed speed is lower than wire
feed speed command. Check for
obstructions in the wire feed system or a
faulty wire drive system. Press Jog/Purge
button to clear error.
ROBT MEM
•
The robot memory error indicates robot
lost memory data. Press Jog/Purge button
to clear error.
E STOP
•
The emergency stop error occurs if the
user presses an emergency stop button.
Reset the emergency stop button and press
Jog/Purge button to clear error. Only applies
to units equipped with E stop option.
RMD DONE
•
The RMD done message indicates the
RMD demo is completed. Pressing
Jog/Purge button will change the screen to
CYCL PWR on the display. Turn unit power
off and back on again.
OVER AVG
•
The over average error indicates that
current is outside the average range for the
set program parameters. Check and correct
program parameters. Press Jog/Purge
button to clear error.
UNIT COMM
•
The unit communication error indicates
the data bus on the PCM board is not
functioning properly. Press Jog/Purge
button to clear error.
OVER CRNT
•
The over current error indicates welding
power source primary current of the inverter
is too high. Turn welding power source off
and disconnect unit for servicing.
Attempting to reset the display to
continue welding may further damage
internal components. A complete
prepower check of the unit is needed
including resistance measurements of R1
and R8 resistors on welding power source
Interconnect board. Resistors should
measure 30K ohms. Visually inspect
electrolytic capacitors C1 and C2 for any
possible damage. In the event of an over
voltage condition, R1 and R8 could open
potentially causing an imbalance in the
power circuit. This condition would create
excessive current in the inverter primary
transformer and result in the OVER CRNT
error.
