Failure
Code 1
Code 2
Explanation(s)
Solution
Impossible to do
vacuum under
-0.1 bar (-0.01
MPa)
/
/
-Exhaust gas circuit
is closed.
-Inlet gas circuit is
open.
-Important
leakage.
Check the position of the valves.
Check the outlet flange for dirt.
Check if the tube is broken (It is
possible to turn the tube slightly
to one side, if it turns to the
other side too, it is certainly not
broken)
Vacuum test is
negative
(impossible to
maintain static
vacuum under
-0.9 bar (-0.09
MPa) for more
than 5 min.
/
/
Small leakage.
Check the flange seals.
Impossible to
maintain a
constant inlet gas
flow of 0.3 L/min.
/
/
0.2 Bar (0.02 MPa)
gas supply is not
stable.
Use an appropriate gas supply
(double stage 0.1 bar (0.01 MPa)
precision
→
cf. Facility Guide)
The bubbler
doesn't bubble
while the
flowmeter and
valves (inlet and
outlet) are open.
Tube pressure
is at 0 bar
(MPa)
/
No gas supply.
The gas supply
circuit is closed.
Turn off the furnace (hold or
stop-state).
Check the flow meter and the
inlet valve installation.
Check the gas supply.
The tube
pressure is
≥
0.2 bar (0.02
MPa)
/
Outlet flange is
clogged.
Switch off the furnace (hold or
stop state).
Check the installation of the
outlet valve.
Check the outlet flange for dirt
(after the furnace has cooled
down).
