Error Description
Check the true gas pressure and make sure there are no
blockages in the gas hoses to which gas sensor (74) is
fitted.
Check the connections of gas sensor (74) to panel board
(24). Replace panel board (24) and/or gas sensor (74).
Check true gas pressure.
Check the connections of gas sensor (74) to panel board
(24). Replace panel board (24) and/or gas sensor (74).
Remove the start command.
The start command can be provided through the CN3
connector or with the CAN bus-1 serial line (see Data
Process Image manual, code. 3.300.363-B supplied with
the power source).
Replace panel board (24).
Replace thermostat (21) on the pilot arc inverter heatsink
on the console.
Check the wiring between precharge board, BR connector
on the power source and pressure switch on the cooling
unit.
Replace the pressure switch on the cooling unit and/or the
precharge and/or control boards on the power source.
Check the true flow rate in the cooling circuits and that
there are no blockages in the pipes. Check the connections
of flow detectors (42) to console panel board (24).
Replace flow detectors (42) and/or panel board (24).
Check the true gas pressure and make sure there are no
blockages in the gas hoses to which gas sensor (74) is
fitted.
Check the connections of gas sensor (74) to panel board
(24). Replace panel board (24) and/or gas sensor (74).
Check true gas pressure.
Check the connections of gas sensor (74) to panel board
(24). Replace panel board (24) and/or gas sensor (74).
Check the true plasma gas flow.
Check the connections and the correct operation of
proportion solenoid (65) and flow detector (60).
Replace proportional solenoid (65) and/or flow detector
(60) and/or panel board (24).
