2 Maximum warming-up
time exceeded
• Device is operated outside the permit-
ted ambient temperature range
• Errors in temperature control
• Check the ambient temperature of the
analyzer
• Check if there are additional messag-
es and follow the instructions
11 Maximum temperature
exceeded. Heaters turned
off.
• Safety function
• Ambient temperature too high
• One or more heater control loops
faulty
• Wait until the device has cooled down
• Then acknowledge the message
•
You should also note the messages in
the logbook
19 Temperature on meas-
urement block too high
• Device is operated outside the permit-
ted ambient temperature range
Error in the temperature control
• Check the ambient temperature of the
analyzer
• In the menu "[3.05.1.3] Heating con-
troller", check the temperatures of the
measurement block and analyzer
module
21 Temperature on meas-
urement block too low
• Device is operated outside the permit-
ted ambient temperature range
• Errors in temperature control
• Check the ambient temperature of the
analyzer
• In the menu "[3.05.1.3] Heating con-
troller", check the temperatures of the
measurement block and analyzer
module
22 Calibration tolerance
exceeded at zero point
• Zero gas changed, setpoint faulty
• Drift heat conductor sensor
• Check the setpoint for the zero gas
calibration in the menu "[2.08.1.1]
Setpoints"
23 Validation tolerance ex-
• Calibration successful • Carry out a zero gas calibration
24 Calibration tolerance
exceeded at span point
• Span gas changed, setpoint faulty
• Drift heat conductor sensor
• Check the setpoint for the span gas
calibration in the menu "[2.08.1.1]
Setpoints"
25 Validation tolerance ex-
• Calibration successful • Carry out a span gas calibration.
26 Measured value outside
the physical specifications
• Wrong gas mixture (extraneous gas-
es)
• Wrong sample gas pressure:
pressure is outside the specification
• Check the sample gas concentration
and the sample gas pressure
• Carry out a zero point and full-scale
value calibration if necessary
28 Control reserve used up
• High fluctuations in the thermal con-
ductivity sensor due to influence of
foreign matter, e.g. condensation res-
idues, dirt particles
• Check the zero gas and reference
gas supplies
