Error Code Meaning
This indicates that the output from the
sensor is too low due to either:
a. a faulty sensor which may be poisoned
or damaged.
b. the calibration gas is incorrect. Check
the calibration gas bottle certificate and
age.
c. sticky gas such as chlorine or
ammonia is not reaching the sensor.
Not applicable
Calibration Signal Too High
The calibration signal too high message
is displayed during calibration when the
sensor span signal is above the pre-
configured levels and a span calibration
can not be achieved.
This indicates that the output from the
sensor is too high due to either:
a. a faulty sensor, bad cabling or wrong
sensor defaults in configuration.
b. the calibration gas is incorrect. Check
the calibration gas bottle certificate and
age.
Calibration Gas Too Low
The calibration gas too low message is
displayed during calibration when the
calibration gas is adjusted to a level below
the pre-configured level.
This would not be indicated under normal
local operation since the pre-configured
operational data of the Engineering Card
push-buttons will prevent this type of
adjustment.
