Error Code Meaning
In some instances this error can be
caused by short circuits in the sensor or
cabling.
The channel card should be calibrated
and its operation checked.
Signal Over Range
The signal over range warning message is
displayed when the sensor signal reading is
more than a predetermined level held within
the channel configuration data. This
predetermined level is above the operating
range.
This provides a warning that the sensor is
detecting a level of gas exceeding the set
operating range of the channel.
The reset of a latched signal overrange
warning condition should only be carried out
after checking that the sensor is in clean
(non target gas) air.

Calibration Errors

Error Code Meaning
Uncalibrated
The uncalibrated message is displayed
for new channel cards that have never been
calibrated.
The channel card should be calibrated and
its operation checked.
Calibration Overdue
The calibration overdue message is displayed
when the pre-configured calibration interval
has expired.
This is a warning message that the sensor
is due for calibration. Once the calibration
has been completed the message will clear.
