Problem
Possible Causes
/ Solutions
5. PLASMA GAS LED
illuminated:
5.1. Plasma gas pressure too low.
This LED will extinguish when PS1 and/or PS2 in the gas
console senses plasma gas pressure of 80 psi (5.5 bar) or
greater.
• Verify that plasma gas supply is set to 120 psi (8.3 bar) as
defined in
Section 2
of this manual.
• Verify that all plasma gas connections are secure, and
that there are no leaks in any hoses connected to the gas
console.
5.2. Pressure switches PS1 and/or PS2 not functioning.
These switches are normally open, and close when plasma
gas pressure is at or above 80 psi (5.5 bar). After PS1 and
PS2 are closed (in O
2
mode) or PS1 is closed (in N
2
mode),
the
PLASMA GAS
LED extinguishes.
• Using the wiring diagrams, check pins, connectors and
associated wiring from the power distribution board
(PCB1) to PS1 and PS2.
Repair and/or replace defective component(s), if necessary.
6. COOLANT TEMP LED
illuminated:
6.1. Coolant too hot
.
This LED will extinguish when temperature switch TS2
senses that the temperature of coolant in the coolant
reservoir is under 160°F (71°C).
• Check to see if water coolant is above 160°F.
• Check to see if TS2 (located in the coolant reservoir) is
open. TS2 is normally closed, and is opened when a
temperature above 160°F (71°C) is reached.
• Using wiring diagrams, check pins, connectors and
associated wiring from REC3 on the power distribution
board (PCB1) to PS3.
Repair and/or replace defective component(s), if necessary.
