Solutions
0-13-0 AC input unstable (line
resonance): Warning.
Blinks
(3 Hz)
Off
• Perform a cold restart.
• If the fault does not clear, correct the
power source. Change the character,
generally the impedance, of the line.
0-19-9 Power board hardware
protection. One or more major
power board hardware faults
(or electrical noise) detected:
Warning.
Fault 0-19-9 can occur three or
more times before becoming a
0-99 fault.
If fault code 0-19 appears upon
power-up, wait one minute to
see if fault code 0-99 appears.
This could indicate a faulty
auxiliary switch.
On On
The inverter shuts down and does not fire
again for several seconds. If the fault is
caused by electrical noise, the fault clears
in a few seconds and the machine operates
normally.
If a true fault continues to occur, the 0-99
fault code appears on the operator screen:
• Access the fault log in the service screen
to identify the major fault.
• Perform Test 12 if fault code 0-99 occurs
after fault code 0-19 displays for one
minute.
0-20-0 Low gas pressure
The gas pressure has fallen
below the minimum pressure for
that process, mode, and lead
length.
On On
• Ensure the gas line is properly installed.
• Replace the air filter element if dirty.
• Replace the gas supply line if restricted.
• Ensure the inlet pressure is 5.9 to 9.3 bar
(85 to 135 PSI).
With proper air connected, measure the
resistance between J5 pins 1 & 2.
• If short, replace the power board.
• If open, check the cable harness between
J5 and the pressure switch. If the harness
is good, replace the pressure switch (kit
228688).
• Perform Test 10.
