Error Remedy / Comments
4-1 Coolant Level low Check coolant level, add as needed.
4-2
Low coolant flow
Fault response time: Process Never started since last power cyle: Below 0.7 GPH
for 15 Seconds. Else below 0.5 GPH no delay or after 3 seconds if below 0.7
GPH Possible cause: Suction leak introducing air into coolant, suspect rear
panel filter seal; clogged filter; defective pump.
4-3
Coolant overheated
Coolant return temperature exceeded 70 degrees Celcius (158F). Coolant fan
failed; radiator fins clogged with dirt; operating with side panel loose or re-
moved. Ambient temperature > 40 deg C.
4-4 Coolant System not ready.
Proper coolant flow of 0.7 GPH was not obtained during up to 4 minutes of
Priming. New installation can require additional Priming cycle(s) to fill hoses
with coolant; cylce power to restart Priming; Suction leak introducing air into
coolant; suspect rear panel filter seal; Clogged coolant filter; Damaged torch
coolant tube; Defective pump assembly.
4-5 Low Coolant Level Warning Low coolant level during cut, does not stop cut.
Add coolant as required.
