Is a specialty purge necessary?*
Do a specialty purge.
Continue to Wait for Start state (5).
Yes
Stage 1: Operate preflow gasses.**
No
Is the coolant flow in the
permitted range?
Continue troubleshooting steps to identify the
problem. Measure the coolant flow again.
No
Yes
Start the coolant pump, and let the coolant
solenoid start the flow of coolant.
Stage 2: Operate cutflow gasses.**
Measure the coolant flow rate.
* A specialty purge (with N
2
or air) occurs automatically if the process changes from a non-mixed-fuel gas
to a mixed-fuel gas or F5 process (or the opposite).
■
If the process that was sent before was a water (H
2
O) process, a water purge is added to the gas
purge. Refer to Automatic purges on page 229.
■
If the process that was sent before was not an H
2
O, mixed-fuel gas, or F5 process, do the usual two-
step gas purge.
** These conditions have an effect on the time that is necessary to complete a purge:
■
The type of operator-selected process that the CNC or wireless device sends to the cutting system
■
If this is the first process sent after the Power-up state (1) starts
■
The type of operator-selected process that was sent before
