Error code: Error message
Cause
¡ Internal hardware problems.
Error code: Error message
Cause
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.
¡ The water trap is clogged.
Error code: Error message
Cause
¡ The version of the control software and
the software of the internal computer do
not match.
Error code: Error message
Cause
¡ The autosampler is not switched on.
¡ The connection cable is not connected or
is faulty.
Error code: Error message
Cause
System is leaking:
UV reactor faulty (fractures on the con-
¡
nections).
¡ TIC condensate container faulty (frac-
tures on the connections).
¡ The connections on the TIC condensate
container are leaky.
¡ The connection on the water traps are
leaky.
¡ The aerosol/water trap is clogged.
¡ The hose pump is leaky.
Error code: Error message
Cause
Communication error.
¡
NDIR detector faulty.
¡
Error code: Error message
Cause
The analog values of the detector are
¡
outside of the working range.

7: COM 2 not found
8: COM 3 not found
9: COM 4 not found
Remedy
¡ Switch the analyzer off/on.
10: Gas pressure error
Remedy
Search for and replace the component
¡
causing the gas pressure error, see be-
low.
¡ 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.
12: Incorrect version number
Remedy
¡ Perform a software update.
13: No connection to sampler
Remedy
¡ Switch on the autosampler and initialize
the analyzer.
¡ Check the connection cables.
15: No gas pressure
Remedy
Check the glass components. If these are
¡
defective, replace these with new ones.
¡ Check the FAST connectors on the TIC
condensate container and the water
traps.
¡ Replace the water traps.
¡ Check the hose pump. If necessary, re-
place the pump hose.
¡ Initialize the analyzer.
20: No connection to optics (NDIR)
21: CRC error optics
22: Status error optics
26: Optics error; incorrect command return
Remedy
Initialize the analyzer.
¡
Inform the service.
¡
24: Optics error, analog values out of range
Remedy
Check the quality of the carrier gas.
¡
Initialize the analyzer and check the
¡
analog values via the component test.
