multiWin: Communication error - incorrect command set between PC and device
Cause
Solution
Internal and external program versions do not match.
Repeat update.
multiWin: no connection to temperature controller
Cause
Solution
Basic device not switched on.
Interface cable between module with internal
computer and basic device not connected or
faulty.
Temperature controller faulty.
Switch on basic device and re-initialize multiWin 1 min.
later
Check the connection of the interface cable
No connection to the autosampler
Cause
Solution
No communication between basic device and
autosampler
Sampler not switched on
Connection cable not connected or faulty.
check connection cable
Switch on sampler and initialize analyzer.

Analytical problems
8.6.1
C/S determination
Recovery generally too low
Cause
Solution
Desiccant too moist
Sooted filter and measuring gas hoses
Leaks
Inspect and replace desiccant
Inspect and replace filter
Inspect the dust trap, if heavily contaminated
(particle deposits) clean the dust trap
In case of leaks inspect the sealing rings in the gas sluice
and the dust trap, replace cracked / brittle sealing rings
Low results for TS
Cause
Solution
Halide trap still in the measuring gas flow
Replace the halide trap with an empty glass tube
Digestion temperature too low
(especially with sulfatic bonding)
Increase the furnace temperature in the method if
the S measuring graph is highly irregular or has a long
tailing and does not drop to the baseline.
If necessary, add additives (e.g. iron phosphate,
tungsten oxide, vanadium pentoxide, tin…).
Contamination of the hoses carrying measuring gas up
to the optics
Remove hoses up to the NDIR optics, clean,
dry and reinstall.
We recommend to have the hoses cleaned by the Ser-
vice department.
