• After delay, wait for CAN watchdog message from the gas console.
• After CAN watchdog messages have been received, send a CAN reset message to the gas console
and go to the Purge state.
Error checking
• Verify that Start signal is off (050).
• Check for coolant flow at power-up (109).
• Check for no chopper current (102).
• If no CAN watchdog message after 6-second delay, report error "UNKNOWN GAS CONSOLE"
(133).
2. Purge
• Turn on coolant pump or motor.
• Gas console runs preflow gases for 12 seconds.
• After preflow cycle is done, verify coolant flow.
• Gas console runs cutflow gases for 12 seconds.
• Verify that the Plasma Start signal is off before going to Idle2 state.
Error checking
• If coolant flow rate is less than 1.1 lpm (0.3 gpm) (093), shut down the system.
• If coolant flow rate is less than 2.2 lpm (0.6 gpm) (060), continue pumping coolant until flow is above
2.2 lpm (0.6 gpm), with no start allowed at this time.
3. Idle2
• If Start signal is active, the gas console goes into Preflow state, the contactor and the soft-start
controller turn on, and system goes into Preflow state.
• If the gas console or serial interface requests a state change, take action.
• After more than 10 seconds since the last Start signal, turn off the contactor and soft-start controller.
Error checking
• Check for coolant flow at power-up (093)
• Check for no chopper current (102).
• Verify that all temperatures are below the specified temperature limits.
4. Preflow_IHS
• Chopper setpoint = pilot arc current.
• Wait for preflow to finish (2 seconds if contactor timeout, otherwise 0.5 seconds) and for the Hold
signal to be removed.
Error checking
• Check for coolant flow at power-up (093)
• Check for over/under line voltage (047/046)
• Check for coolant over temperature (071).
• Check for chopper over temperature (065).
• Check for transformer over temperature (067).
5. Pilot Arc
• Turn on pilot arc controller and pilot arc relay.
