FAULT
INDICATION
CONDITION CAUSING FAULT
SUGGESTED REMEDIAL ACTION
“Calib Zero”
appears in the
display window
When trying to calibrate the zero
of an infra red sensor (CO2), it
has been determined that the
sensor is too far from the correct
point in order to perform a
calibration successfully.
Attempt recalibration of the sensor using
the correct gas and procedure. If the
fault persists, fit spare sensor unit
–
contact Analox for repair of faulty unit.
“CAL LO ERR”
When trying to calibrate the Cal-L
point of a sensor, it has been
determined that the sensor is too
far from the correct point in order
to perform a calibration
successfully.
Attempt recalibration of the sensor using
the correct gas (or temp/humidity) and
procedure. If the fault persists, fit spare
sensor unit
–
contact Analox for repair of
faulty unit.
“CAL HI ERR”
When trying to calibrate the Cal-
H point of a sensor, it has been
determined that the sensor is too
far from the correct point in order
to perform a calibration
successfully.
Attempt recalibration of the sensor using
the correct gas (or temp/humidity) and
procedure. If the fault persists, fit spare
sensor unit
–
contact Analox for repair of
faulty unit.
“OEM Sensor
Fault” appears in
place of sensor
reading,
The Remote sensor unit is unable
to obtain readings from an infra-
red sensor (CO2) or a
Temperature/Humidity sensor
Power system down and then restart. If
the fault persists fit a spare sensor unit
–
contact Analox for repair of faulty unit.
“No flow” appears
in the display
window
The remote sensor unit cannot
detect gas flow through the
sensor unit (only for systems
with flow switches fitted (ie
sample fed, and/or pump drawn
samples)
Check that there is sample flow through
the unit (feel exhaust). If fault persists ,
investigate operation of flow switch and
fit spare if necessary
“ADC Flt” appears
in the display
window
The remote sensor unit has
detected a fault with its internal
ADC.
Power system down and then restart. If
fault persists fit spare sensor unit
–
contact Analox for repair of faulty unit
“EEPROM Flt”
appears in the
display window
The remote sensor unit has
detected a fault with its internal
EEPROM
Power system down and then restart. If
fault persists fit spare sensor unit
–
contact Analox for repair of faulty unit
“CODE ERR”
appears in place
of time field
There is corruption detected
within the code space of the
Operator Console
Contact Analox for assistance
“RAM ERROR”
appears in place
of time field
There is corruption detected
within the RAM memory space of
the Operator Console
Repower the system once. If the fault
persists contact Analox for assistance.
“E2 ERROR”
appears in place
of time field
There is corruption detected
within the E2PROM configuration
space of the Operator Console
Contact Analox for assistance
