Display shows any of the following:
Err 020
Err 100
Err 200
Err 201
Err 210
An attempt was made to reprogram
a CB or feed head but the program
did not verify.
The Power Source issued a shut
down command for some reason.
No Heart beat response from the
PS.
No heart beat response from an
object.
EEPROM error.
Check for potential electrical HF
noise generators in the area. Try
removing the noise source and pro-
gramming again. If the Err 020 still
occurs, either replace the EEPROM
chip(s) in the board being repro-
grammed or replace the whole PC
board being reprogrammed.

If this occurs while welding, the sta-
tus LED should be flashing red on
the object that lost heart beat.
Otherwise, look for any nodes that
are flashing green. This indicates
they have not been recognized and
there is a power source problem
(see power source trouble shooting
section). If the status LED is either
flashing or solid red, there may be a
problem with continuity in the com-
munication lines. Check the lines for
continuity, in the cable and harness-
ing (refer to wiring diagram).
Parameter recalled at power up was
out of range. Rotate Encoder Knob
to reset. Check all settings before
proceeding to weld. If this condition
persists then replace the CB mother
PC board.
