ment or halogen trap maintenance).
¡
The connection between the combustion
tube and the condensation coil or the
screw connections are leaky.
¡
Check the connection of the combustion
tube to the condensation coil, in particu-
lar the fork clamp position.
¡
The combustion tube is faulty (cracks,
fractures at the edge).
¡
TIC condensate container faulty (frac-
tures on the connections).

Out > 170 ml/min
Cause
Remedy
¡
The MFM (mass flow sensor) is faulty.
¡
Check the flow with an external mass
flow sensor if possible to confirm the er-
ror.
¡
Inform the service.
¡
The filling of the halogen trap is used
up.
¡
Check the halogen trap.
Error indication

No carrier gas.
¡
The hose line is leaking.
¡
Turn on the carrier gas on the pressure
reducer.
¡
Search for and remedy the leak.
¡
The inlet pressure of the carrier gas sup-
ply is too low.
¡
Set the carrier gas inlet pressure cor-
rectly.
¡
The pressure switch in the analyzer was
triggered simultaneously with error 10:
Gas pressure error.
¡
See the remedy for 10: Gas pressure er-
ror.
¡
The MFC is faulty.
¡
Inform the service.

Cause
Remedy
¡
The Peltier cooling is insufficient, simul-
taneous with error message Peltier tem-

condensate container. The formation of
condensation water on the cooling block
indicates that the cooling is working.
¡
The MFC is faulty.
¡
Inform the service.
