tion Description Possible causes/remedy
System
Lamp perform‐
ance
M aint.
Warning: Lamp performance < 20%. Prepare to exchange the lamp, see "Replacing
the sender lamp", page 80 .
Lamp perform‐
ance limit
M aint.
Lamp performance too low.
Lamp mini‐
mum
M aint.
Lamp adjustment: Signal too high for minimum
lamp current and exposure. Check parameter settings.
Lamp 4Q max
M aint.
The lamp current must be set to 1000 mA (stop)
in the alignment procedure. • Alignment, check the optics, see "Align‐
ment check (option) - automatic optical
alignment check", page 69
.
• Possible lamp change, see "Replacing the
sender lamp", page 80 .
• Correct parameter settings.
Flashcard
missing
M aint.
No Flashcard found. Insert the Flashcard, replace a possibly defec‐
tive card.
IO com.
M aint.
Communication fault to IO block. • Connection interrupted, check the cable.
• Defective CAN-bus interface.
Spectro no
answer
M aint.
No data received from spectrometer. Malfunction on the interface to the spectrome‐
ter. Check the plug.
Cycle span
drift
M aint.
The measurement on the control filters showed
an excess deviation. The reference from the adjustment is not cor‐
rect. Check limit value parameter setting.
Cycle zero drift
M aint.
The zero point measurement of a measured
value showed an excess deviation. Check limit value parameter setting.
Cycle wave‐
length drift M aint.
.
The check of the current Lambda_C0 coefficient
showed an excess deviation.
Cycle peak
position
M aint.
The check of the position of the peak of the NO
cell showed an excess deviation • Check limit value parameter setting.
• Defective NO cell.
Cycle peak
width
M aint.
The check of the peak width of the NO cell
showed an excess deviation.
Cycle cell
empty
M aint.
During the check of the NO cell it is determined
that the highest measured extinction value in
the evaluation range is <0.1. Cell is empty.
Temp control
voltage low
M aint.
The measured voltage supply value is too small
(< 20 V). Malfunction of temperature control unit.
Temp control
lamp fan
M aint.
The lamp fan has a malfunction. Malfunction:
• Temperature control unit
• Fan
• Cabling
Temp control
optic fan
M aint.
The fan of the optic carrier has a malfunction.
Temp control
spectro fan
M aint.
The fan of the spectrometer has a malfunction.
Temp control
electronic
temp
M aint.
Temperature of the temperature control elec‐
tronics >100 °C. Malfunction of temperature control unit.
Temp control
spectro temp
M aint.
SR-unit is too warm or too cold.
•
In the heating phase: Normal.
•
When running: Check ambient tempera‐
ture.
Data logging:
writing data
M aint.
Error when writing logging data to the Flashcard. Flashcard memory full, Flashcard defective.
Data logging:
open file
M aint.
Error when opening a file for logging data on the
Flashcard.
System I/O
Error
M aint.
