The measurement display is shown in Figure 2. The top line of
the display shows the current measured value (with its units) for
each of the sensors fitted.
In normal operation the bottom line of the display labels the
gases measured. Should a fault or alarm occur then the lower
line of the display will detail the nature of the fault or alarm.
Should more than one fault and/or alarm be active then arrow
keys on the keypad may be used to scroll through these
messages.
The fault messages that may appear are as follows:
OXYGEN LOW Oxygen too low for reliable COe
measurement
OXYGEN °C LOW Oxygen sensor temperature too low
OXYGEN °C HIGH Oxygen sensor temperature too high
COe mV LOW Combustibles sensor output voltage
low
COe mV HIGH Combustibles sensor output voltage
high
COe °C LOW Combustibles sensor temperature too
low
COe °C HIGH Combustibles sensor temperature too
high
SENSOR °C HIGH Sensor head temperature too high
(OPTIONAL)
SENSOR °C LOW Sensor head temperature too low
(OPTIONAL)
AUTO CAL FAIL Autocalibration out of tolerance error
COe mV OUTPUT LOW Combustibles sensor sensitivity low
(updated after calibration only)
COe CONC HI Combustibles sensor has been
exposed to very high Coe levels
mV
OUT OF TOLERANCE
Combustibles sensor mV greater than
+/-60mV
DISPLAY OVER RANGE Measurement is too large to display
COe WARMING Combustibles sensor is warming up
O
