Automated diagnostic tests
Move the process selection knob on the power supply to the TEST position while the machine is idle and the system will
run the following tests automatically:
1. The system tests the chopper. The Amps display will show the open circuit voltage (OCV). A normal reading is
approximately 300 VDC.
2. The plasma select valve (SV1) turns on for 3 seconds.
3. The shield off-valve (SV2) turns on for 3 seconds.
4. The preflow off-valve (SV3) turns on for 3 seconds.
5. The plasma off-valve (SV4) turns on for 3 seconds.
6. The vent off-valve (SV5) turns on for 3 seconds.
7. (Fuel Gas Console Only) The off-valve closes and the inlet valves open until the system is pressurized, and then
they close. The system should maintain pressure. If a leak is detected, the HSD130 will display an error code. Put the
toggle switch in the Error position to monitor for errors.
8. (Fuel Gas Console Only) The inlet valve closes and the off-valve opens until the pressure in the system is released
and then it closes. The system looks for an increase in pressure. The test ensures that the valves are closing properly
and are not allowing gas to leak through. Put the toggle switch in the Error position to monitor for errors.
The following error codes may be seen during automated tests 7 and 8:
Error 012 – Test in progress – Wait for test completion.
Error 014 – Test failed – Plasma gas channel
Error 015 – Test failed – Preflow gas channel
Error 016 – Test failed – Shield channel
Note: When the process selection knob is in the TEST position the display will alternate between “-26” (test
position) and “012” (test in progress). If the error code changes from “012” to “000”, the system
passed all tests.
