330 Pressure above or below upper
and/or lower limit value 2.
x
Air = combustion air,
H2 = combustion gas.
331 The output variable of the
pressure regulator is out of
range.
x x Fidas24: Check the supply gas pressure.
I/O devices
332 Auxiliary voltage failure on I/O
board.
x x Defective I/O board. Replace the board.
333 Unavailable I/O type config-
ured.
x x Correct the configuration with the test and calibration
software.
334 No new measured values from
the analog/digital converter.
x x Defective I/O board. Replace the board.
335 The measured value exceeds
the range of the analog/digital
converter.
x x Check signals at analog inputs.
If OK, check the configuration and calibration of the
analog inputs.
336 A calculation error occurred
during calculation of the meas-
urement value.
x x Check the configuration and calibration of the analog
inputs and outputs.
337 Broken analog output line x x Check the analog output lines.
338 Line break in the digital input
(moisture sensor).
x x Check moisture sensor in the system cooler.
339 Line break or short circuit in the
analog input.
x x Check system cooler temperature.
340 Analog input value exceeds
upper or lower limit value 1.
x Check system cooler temperature.
341 Analog input value exceeds
upper or lower limit value 2.
x Check system cooler temperature.
Flow monitor (pneumatic module)
342 The flow rate undershoots limit
value 1
x Check sample preparation.
Alarm value 1 = 25 % of MRS.
343 Flow rate undershoots limit
value 2.
x x Check sample preparation.
Alarm value 2 = 10 % of MRS.
Automatic calibration is interrupted and disabled
Measured value
344 Measured value overshoots
measuring range value.
Measured value > +130 % of MRS, not logged
345 Measured value undershoots
the measurement value range.
Measured value < −100 % of MRS, not logged
Limas
356 The analyzer in warm-up phase. x x Status message during warm-up phase.
If the status message appears after warm-up, a temper-
ature error has occurred in the lamp or in the sample cell
or in the measurement or reference detector amplifier.
Notify Service.
357 Limas motor optimization in
progress.
x x Status message after warm-up phase
Motor optimization should be concluded after approx.
2 minutes. If the status message is still present after-
wards, a filter wheel or the calibration wheel is blocked,
e.g. by a loose cable. Check cable and clip on.
