Error code: Error message
10: Gas pressure error
Cause
Remedy
¡
Counterpressure in the analysis system
too high: The carrier gas supply is auto-
matically interrupted to protect the ana-
lyzer. In flow indication is approx. 0 ml/
min.
¡
Search for and replace the component
causing the gas pressure error, see be-
low.
¡
The water trap is clogged.
¡
Undo the connection upstream of the
water traps and reinitialize the analyzer.
¡
Check if the gas pressure error occurs
again. If not, replace the water traps.
¡
No gas flow at the measuring outlet due
to kinked hose for sample gas supply.
¡
Check the hose. If necessary, eliminate
any kinks.
¡
The condensation coil is clogged with
catalyst balls.
¡
Interrupt the measuring gas flow be-
tween the combustion tube and conden-
sation coil. Check if the gas pressure er-
ror occurs again. If not, rinse the con-
densation coil with ultrapure water.
¡
When replacing the catalyst, always fill
in enough quartz glass wool as the first
layer.
¡
Heavy salt deposits in the combustion
tube. (During analysis of highly saline
samples, salt deposits can form in the
combustion tube.)
¡
HT mat used up by analysis of highly
saline samples.
¡
Replace the HT mat in the combustion
tube, or replace the catalyst. Select the
measure depending on the number of
measurements with the current catalyst
filling and the activity of the catalyst.
¡
The gas supply to the furnace head is
clogged.
¡
Clean the gas supply to the furnace
head.

12: Incorrect version number
Cause
Remedy
¡
The version of the control software and
the software of the internal computer do
not match.
¡
Perform a software update.

13: No connection to sampler
Cause
Remedy
¡
The autosampler is not switched on.
¡
The connection cable is not connected or
is faulty.
¡
Switch on the autosampler and initialize
the analyzer.
¡
Check the connection cables.
Error code: Error message
15: No gas pressure
Cause
Remedy
¡
Gas connection not present or faulty.
¡
Connect the carrier gas. Check the inlet
pressure.
Error code: Error message
16: TC lock failure (folding head)
Cause
Remedy
¡
The automatic lock does not open.
¡
Check the gas pressure of the auxiliary
gas for locks. Check the inlet pressure.
¡
Check the hose connections of the locks.
