Liquiline System CA80SI Diagnostics and troubleshooting
Endress+Hauser 111
Problem Possible cause Tests and/or remedial measures
No reagents / sample 1. Check levels
2. Check the hoses of the reagents
3. Check sample
Cell dirty 1. Perform calibration with standard
2. Clean using manual cleaning routine,
then repeat calibration with standard
Incorrect reagent
‣
Check the configured measuring parameter
and the reagents used
Incorrect concentration of
the standard solution
Check the concentration setting for the
standard solution
Reagents have passed their
shelf life
Incorrect hose system
‣
Check the hose system using the hose
routing diagram (see "Commissioning"
section).
Measurement//calibration does
not start
Action still active
Appropriate bottles not
used
‣
Check status
No sample available
Device is in the fieldbus
mode; no manual actions
are possible
Injector run times have
elapsed
Calibration has failed Stability criterion was not
met
1. Check the configuration and perform
manual calibration again
2. Check the hoses of the reagents
Current output, incorrect
current value
Incorrect adjustment
‣
Check with integrated current simulation,
connect mA meter directly to current
output.
Load too large
Shunt / short to ground in
current loop
No current output signal Base module defective
‣
Check with integrated current simulation,
connect mA meter directly to current
output.
