Clearing malfunctions (other malfunctions)
Malfunction
Possible causes
Action
Temperature sensor PT100
defective.
Replace temperature sensor.
Sample gas cooler tempera-
ture too high / too low
Controller defective.
Condensate container
Condensate container full.
Empty condensate container.
Malfunction
Possible causes
Action
Sample gas flow too low
Sampling tube clogged or filter
element in sampling probe
contaminated.
Check, clean and replace sampling
probe, tube and filter element if
necessary.
Sample gas line clogged.
Check and clean.
Wrong flow setting.
Check flow setting on flowmeter.
Setpoint: approx. 60 l/h.
Water trap or glass wool filter
clogged.
Check and replace.
Test gas setting or Measuring
Screen implausible
Warm-up phase of analysis system
not yet finished.
Wait for warm-up phase to finish.
Depending on components to be
measured, measuring ranges and
drift, the warming-up phase takes
up to 24 hours.
Test gas and set test gas concentra-
tion do not match.
Check test gas concentration via the
BCU.
Test gas unreliable, low flow.
Check setpoint value, service life,
pressure and lines.
Gas path leaky or clogged
Check gas path.
Damaged subassemblies.
Check enclosure, water trap and
glass wool filter.
Fluctuating power voltage.
Check power voltage.
Zero point drifting or
sensitivity drifting
Gas path leaky or clogged.
Check gas path for clogs and leak
tightness.
Cooler unstable.
Check cooler.
Test gas unreliable.
Check setpoint value, service life,
pressure and lines.
Flow too low.
Check the setpoint value.
Errors on signal lines
Connections loose or corroded.
Check or replace.
Electromagnetic interference.
Check main power supply for
missing protective conductor.
Check voltage peaks in the network.
Strong radio transmitter in the
vicinity, close enclosure door.
Replace faulty or corroded ground-
ing.
Inadequate power supply.
Check.
Faulty interfaces
Check.
