The Control Board performs several tests to determine the system is ready to operate. During the
self-tests the digital display first shows
number which includes decimals. 1.1.0 is an example of a production released code revision
that may be displayed.
Next displayed is the "checksum" a combination of letters and numbers that are unique to the firm-
ware revision. These are used by service personal to determine if the firmware has been corrupted.
If there are no issues detected the output current setting will be displayed with the letter "A" to
the right, showing the output current setting. Should a problem be detected the fault code in
the format Exxx will display and the "A" will not be illuminated. Refer to Section 5.04 for fault
code explanations.
Gas indicator turns ON if there is sufficient gas pressure for power supply operation and
the cooling fan turns ON. (90 - 125 PSI / 6.2 - 8.6 bar)
NOTE!
Minimum pressure for power supply operation is lower than minimum for torch operation.
The cooling fan will turn ON as soon as the unit is turned ON. After a short amount of time the fan
switches to low speed. The fan will return to high speed as soon as the torch switch (Start Signal)
is activated or if the unit is turned OFF, then turned ON again. If an over temperature condition
occurs, the fan will continue to run at high speed while the condition exists and for a five (5)
minute period once the condition is cleared.
