7 Diagnosis and Trouble-Shooting
7.1 Diagnosis of errors and warnings
ErrorsWhen 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. alarm, Max. alarm or Value hold – the last measured value is kept) and
flashes.
•
The actual error code can be read in V2H0, the last error code in V2H1.
WarningsWhen 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 errror 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 112
PMC 631,
PMC 731
Error No connection to sensor analogue/digital converter
– Cable connection from sensor to main electronics interrupted.
Check cable connection.
– Main electronics defective.
Replace electronics.
– Sensor electronics defective.
Replace sensor.
5
E 113
PMC 631,
PMC 731
Error Measuring error during pressure and temperature measurement
The sensor electronics are no longer correctly converting the measured
pressure and temperature values.
– "Pressure signal" (PIN 6) connection disconnected at the plug.
Reconnect.
Sensor or sensor electronics defective.
Replace sensor.
