Nature Description
Measures
ERROR 1
Critical
Short circuit in the sensor head
cable (in voltage mode)
Check wiring and connections.
Push Enter button.
ERROR 2
Critical
Cable interruption
(in current mode)
Check wiring and connections.
Automatic reset after error correction.
ERROR 3
Critical
Cable too long
(only in voltage mode)
Check wiring and connections.
Check selected program.
Connect sensor head and push Enter button.
Eventually change to 5 wire installation.
ERROR 4
Critical
Sensor power supply voltage
cannot be controlled.
Push the Enter button. If error persists
contact your Compur service partner.
ERROR 5
Critical
Cable interruption
(only in voltage mode)
Check the sensor head power supply,
connection and voltage.
Connect sensor head and push Enter button.
ERROR 6
Non
critical
Zero not found during time limit
Check connections.
If gas is present use zero gas.
Push the Enter button and try again.
The old zero value remains valid.
ERROR 7
Non
critical
Zero shift out of specifications.
Check if gas is present.
Push the Enter button and try again.
The old zero value remains valid.
Eventually replace the sensor.
ERROR 8
Non
critical
Sensor sensitivity too low.
No gas found during calibration.
Check if gas is on and gas adapter tightly
connected. Push ENTER and try again.
The old gain value remains valid.
Eventually replace the sensor.
ERROR 10
Critical
EEPROM writing error
Contact your Compur service partner
ERROR 11
Critical
EEPROM checksum error
Contact your Compur service partner
ERROR 12
Critical
EEPROM reading error
Contact your Compur service partner
GAS
CONC
ERROR
Non
Critical
The result of
gas concentration x response factor
is out of range.
Check gas concentration and response factor
entry. Eventually select another span gas
concentration.
Push the Enter button and try again.
The old gain value remains valid.
Eventually replace the sensor.
CALIBR.
FAILED
Non
Critical
The result of
sensor signal
gas concentration × response factor
is too low.
Check gas concentration and response factor
entry. Eventually select higher span gas
concentration.
Push the Enter button and try again.
The old gain value remains valid.
Eventually replace the sensor.
OFF
Critical
Short circuit during ERROR 2
Check connections and wiring.
Push the Enter button.
