MISADJUSTMENT(S)
FUNCTION PROBLEMS
1. Make sure the WELDING TER-
MINALS switch (S6) is in the
"REMOTELY
position.
2. Install a jumper wire from pins
"D" to "C" on the 14 pin amphe-
nol. If the output contactor acti-
vates, the problem is external to
the RANGER 9. The wire feed-
er or the control cable may be
faulty.
CAUTION
detailed in the beginning of this manual.
RECOMMENDED
COURSE OF ACTION
1. With the jumper installed in pins
"D" and "C" in the 14 pin
CONTROLLED" amphenol, check for 12VDC
from leads #224 (+) to #232 (-)
at the output contactor.
12VDC is present and the con-
tactor does not activate, then
the contactor may be defective.
2. If the correct voltage is NOT
present in step #2, check from
lead #224 to ground (lead #5)
for the presence of 12VDC. If
12VDC is present, then check
the continuity of the lead #232A
to the idler printed circuit board.
3. The printed circuit board may
be faulty. Replace.
4. If 12VDC is NOT present from
lead #224 to ground (lead #5),
then check the #224 lead for an
open circuit.
