ID Command System Description
121 LEAK_CHECK_MODE Manual gas system
Auto gas system
This command will put the system into leak mode. There are
3modes, mode #1 is the inlet leak check mode. This is used to
see if the inlet solenoids are allowing gas to pass through the valve
even when they are closed.
Mode #2 is the system leak check mode which will test for leaks
to atmosphere within the system. Mode #3 is the Burkert valve
flow test. For automatic gas consoles only.
For the inlet leak test, the system should have 0 psi on all gas
channels, and hold at this pressure.
For the system leak test, the system should charge all gas lines,
then hold the pressure.
The Burkert flow test checks for an expected PWM value for a set
pressure and does a gas ramp-down test.
NOTE: This test is preformed using 130 amp O
2
/ Air
consumables and setting the 30 amp O
2
/ O

process
Each test takes about 40 seconds to complete.
This command will only be accepted when the power supply is in
the state IDLE2 (03).
After leak checking is complete the system must be set to mode 0.
An error code will reflect the state of the test. Using the GET_
LAST_ERROR command, you can get the result of the test.
12 = Test in progress
13 = Test passed
14 = Cut gas channel #1 failed
15 = Cut gas channel #2 failed
16 = Plasma ramp-down test failed (Burkert test only)
17 = Shield ramp-down test failed (Burkert test only)
Data:
Mode 0 = run
1 = Inlet leak check
2 = System leak check
3 = Burkert flow check
Return value:
Time for the test to run in seconds, 0 = not accepted
