5 – Troubleshooting and System Tests
 The air inlet filter on the internal compressor
is completely clogged.
For the compressor’s air inlet filter to
trigger this LED fault, the filter would
have to be so blocked that no air can
flow through it.
6. Replace the compressor’s air inlet filter. See
Replace the air inlet filter in the internal
compressor on page 165.
 One of the following internal components is
faulty and needs to be replaced:
 Internal compressor
 Compressor-driver board
 Power board
7. Systematically check the internal compressor,
the compressor-driver board, and the power
board to determine which component needs to
be replaced. Perform Test 9 – internal
compressor, compressor-driver board, and
power board on page 91.
The internal compressor LED and the temperature LED blink
alternately when the machine is powered ON.
Possible causes Possible solutions
 The system was powered on with the torch
trigger being pulled.
 The start circuit is stuck closed.
 Release the torch trigger and reset the
system by turning it OFF (O) and then
turning it ON (I) again. The system
automatically disables itself when the power
supply is turned on while the torch trigger is
pulled.
 Perform Test 6 – plasma start on page 87.
