Gas analyzer problems
Problem Cause Solution
Blinking measurement value
readout
Measured signal violates
measurement range limits
Note: Measurement value > +130 % MRS or
measurement value < -100% MRS. Additionally,
status messages 344 or 345 are generated.

Identify cause (e.g. line break) and repair
Flow problem
External gas lines or filters
dirty, plugged or leaking
Disconnect the gas analyzer from the gas
preparation system
Blow out the gas lines with compressed air or
clear them mechanically
Change the filter elements and packing
Check gas line seal integrity
Gas analyzer gas paths
crimped or leaking
Disconnect the gas analyzer from the gas
preparation system
Check the analyzer module gas lines and the
gas module lines for crimping or loose connec-
tions
Check the integrity of the analyzer module gas
paths and (if applicable) of the lines to the gas
module
Temperature problem
Gas analyzer still in warm-up
phase
Approx. 30 minutes without thermostat
Approx. 2 hours with thermostat
Excessive air movement
Reduce the flow of air around the gas analyzer
Install shielding against draft
Ambient temperature out-
side of permissible range
Protect the gas analyzer from cold and heat
sources such as the sun and vats
Maintain the permissible ambient temperature
range
Gas pump problems
Problem Cause Solution
Low pump output or none
at all
Pump is not connected to
mains
Check the mains connection and the voltage
Suction side (suction filter)
is blocked
Replace the suction filter
Discharge side, connection
hose blocked
Clean or replace the hose
Hoses are defective, bent or
have come off
Replace the hoses or reconnect them
Electrical defect
Return the pump to the manufacturer for re-
pair
Loud noise
Internal parts of the pump
are worn out or are out of
alignment
Return the pump to the manufacturer for re-
pair
