Cause
Pump gas flow too low, mea-
surement is no longer reli-
able
Pump gas flow too low, mea-
surement accuracy reduced
Sensor or device is not oper-
ating in the defined tempera-
ture range
Incorrect calibration
Calibration interval expired
The light transmission is so
weak that the gas concentra-
tion cannot be calculated
with the required accuracy
The device detects weak
light transmission, most likely
due to the contamination of
the optical system
Incorrect alignment of opti-
cal transmitter and receiver
Battery dead
Fault elimination and messages
Cause
Supply voltage of relay
outside approved range
Module error, internal
error with electronic
redundancy
Remedy
Check the hoses for block-
ages and adapt the pump
flow if necessary.
Check the hoses for block-
ages and adapt the pump
flow if necessary.
Operate the sensor or device
in the defined temperature
range.
Repeat calibration.
Calibrate transmitter.
Clean accessible optical ele-
ments.
Clean accessible optical ele-
ments.
Realign the optical transmit-
ter and receiver.
Immediately replace or,
where applicable, charge the
battery.
