7 Diagnosis and Trouble-Shooting
7.1 Diagnosis of errors and warnings
Errors
When the Cerabar S detects an error:
•
an error code is transmitted along with the measured value
•
with a plugged in display, the bar graph adopts the value selected as error code
(min., max., or continue – the last measured value is kept) and flashes.
•
The actual error code can be read in V2H0, the last error code in V2H1.
Warnings
When the Cerabar S detects a warning:
•
An error code is transmitted along with the measured value: the Cerabar S
continues measuring
•
The actual error code can be read in V2H0, the last error code in V2H1.
Error codes
in V2H0 and V2H1
If several errors occur simultaneously, then they are displayed in sequence
corresponding to the priority of the error.
Code
Type
Cause and Remedy
Priority
E 101
Error
Sensor Checksum Error
Error reading checksums from the EEPROM of the sensor.
– Checksum incorrect, transmission error during read process due to
effects of EMC (larger than specified in Chapter 9, Technical Data).
Block EMC effects.
– EEPROM of the sensor defective.
Replace sensor.
3
E 103
Error
Initialisation active
– The electronics are initialised after the device is connected.
Wait for end of initialisation process.
2
E 104
Warning
Sensor calibration
– Values in V7H4 and V7H5 (Low Sensor Trim and High Sensor Trim)
are too close together, e.g. after sensor recalibration.
Reset system (Code 2509), recalibrate sensor.
23
E 106
Error
Download active (Commuwin II)
–
Wait for end of download.
10
E 110
Error
Checksum error
– During a write process (e.g. when display indicates "E 103") the
power supply is interrupted.
Restore the power supply. Reset (Code 5140) if necessary.
– EMC effects (larger than specified in Chapter 9, Technical Data).
Block EMC effects.
– Main electronics defective.
Replace electronics.
1
E 111
Error
No connection to EEPROM of the sensor
– Cable connections from sensor electronics via main electronics to
display (internal bus) interrupted or sensor electronics defective.
Check plug to sensor.
Check cable connection.
Replace sensor.
4
E 113
Error
Measuring errors during pressure and temperature measurement
Incorrect transfer of analogue signals from sensor to main electronics.
– Cable connection between sensor and main electronics interrupted.
Check cable connection.
– Main electronics defective.
Replace electronics.
– Sensor electronics defective.
Replace sensor.
6
E 114
Error
Measuring error during temperature measurement.
Difference between temperature calculated in sensor and measured
temperature is greater than 50 K.
– Cable connection between sensor and main electronics interrupted.
Check cable connection.
– Sensor electronics defective.
Replace sensor.
