Failure, Error and Status Messages
GB
Model 9010/9020 SIL
8.2 Error Indications
These error messages are shown in the display during the calibration or when calibration is
complete.
Display Triggered levels Description
E1
Catalytic combustion detectors:
If signal Ux < 0.1 mV/%LEL
Semiconductor detectors
If the difference between the zero signal and
the full scale signal Ux < 120 mV
4-20 mA Transmitters
If the zero calibration signal is outside of
4mA

10% limits
and if full scale calibration signal is outside of
20mA

10% limits
E1 symbol indicates that detector
sensitivity is too low.
New calibration values will not be
accepted, the original calibration
values are used.
After leaving the configuration menu
E1 symbol toggles with the actual
measured value until new calibration
values are accepted.
If ATEX function is activated then
"Failure" signal is triggered until it is
acknowledged by user
E2
Catalytic combustion detectors:
If the difference between the zero signal and
full scale signal Ux > 200 mV
Semiconductor detectors
If the difference between the zero signal and
full scale signal Ux > 1800 mV
E2 symbol indicates that detector
sensitivity is too high.
New calibration values are accepted.
E3
Catalytic combustion detectors:
If the Ux signal is between 0,1 mV/%LEL and
0,12 mV/%LEL
Semiconductor detectors
If the difference between the zero signal and
the full scale signal Ux < 200 mV.
E3 symbol indicates that detector
needs to be exchanged soon.
New calibration values are accepted.
E4
If the signal e300 mV with the cali-
bration referred to the full scale.
E4 symbol indicates that detector
signal may be out of optimized range.
New calibration values are accepted.
It is recommended to check and opti-
mize a bridge resistance
E5 Detector zero is out of the limits
Ux signal for zero is out of acceptible
limits (-75 to +75 mV)
E10
Appears when the same value is set for offset
value and full scale value.
