9.1 Troubleshooting instructions
Although the analyzer is not very prone to faults due to its simple design, problems at the measuring
point can, of course, not be completely ruled out.
Possible errors, their causes and their possible remedies are thus listed below.
9.1.1 Error messages
9.1.2 System errors/process errors without messages
Error message Possible cause Tests and / or corrective measures
Calibration failed
If a calibration fails, you can enter a new calibration factor manually (CONFIGURATION menu,
"Calibration factor"). Cancel the error message by switching the analyzer off and on briefly.
If the error occurs frequently, you will have to search for the cause.
Air bubbles in system Start calibration manually (PARAMETER ENTRY, "1. calibration", change the date accordingly,
start measurement) or enter a new calibration factor.
Incorrect concentration of standard Check the concentration in the laboratory. Adjust the standard accordingly ("PARAMETER
ENTRY", "Calibration solution") or replace the standard.
Reagents contaminated or aged Simple check: Mix 5-10 ml of standard solution and 5 ml of reagent in a beaker. If it does not
change color after max. 10 min, replace the reagents.
Standard dosing defective Check the valves for contamination, obstructions (visual inspection). Replace valve hoses if
necessary.
Incorrect photometer Check the setting in the CONFIGURATION menu.
Cell dirty Not enough light intensity at
receiver, e.g. due to sedimented
particles – Flush with 12.5% bleaching lye (monthly maintenance)
– When using a CAT 430:
Check the filter.
Incorrect photometer Incorrect photometer Check the setting in the CONFIGURATION menu, "Photometer".
No sample
No sample Establish sample transfer.
Level measurement defective Check level measurement at the sample collector.
Spillage error
Leak at canisters or hoses Replace defective components and clean and dry the analyzer or those components affected by the
leak.
No measuring signal
Cell filled with air Pump sample for 1 minute (SERVICE).
Photometer defective Inform Service
Electrical connection Check all electrical connections and make sure the fuses are firmly seated.
Fuse defective Replace fuse F4 or F5 (semi-delay 0.2 A)
Error Possible cause Tests and / or corrective measures
Measured values always
the same
Reagents contaminated
or aged Simple check: Mix 5-10 ml of standard solution and 5 ml of reagent in a beaker. If it does not change color
after max. 10 min, replace the reagents.
No sample, no reagents Make sure sample and reagents are supplied, check level monitor and clean if necessary
System blocked Flush with 12.5% bleaching lye (monthly maintenance)
