Group 4 -- Torch Coolant System
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 removed.
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 Prim-
ing. 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.
Group 5 -- Gas Control Communications Port
5-1
CANBUS Acknowledge fault. Message sent over CANBUS (Fiber-optic) was not acknowledged as received by
DMC. CCM to DMC Fiber-optic cable not properly connected, dirty or defective;
DMC power supply or Control PCB defective; CCM defective.
5-2 CANBUS Off Excessive communication errors resulted in communication with DMC to turn off.
Dirt on fiber ends or in connectors, blow out with clean dry air; fiber not locked
into connector; sharp bends in fiber; fiber defective;
5-3 CANBUS Errors Warning. Communication with DMC has required a signifcant number of message retries
due to communication errors. Dirt on fiber ends or in connectors, blow out with
clean dry air; fiber not locked into connector; sharp bends in fiber; fiber defective;
5-4 Reserved No information available; Contact customer service
