The display shows “Err.Sens.xx Stat: nn”
with xx: sensor number, for example 01
nn: error code (refer to the following table)
| Error code | Error description | Help |
| 01 | Sensor does not respond via interface “loop out” (connector 4) | Restart system by pressing the ESC button |
| 02 | Sensor does not respond via interface “loop in” (connector 5) | |
| 03 | Sensor does not respond at all | |
| 13 | Sensor will not be read any longer | |
| 20 | Sensor initialising error | |
| (connectors see Appendix Fig 12.11) | ||
If multiple errors are detected, the error code is calculated as the hexadecimal sum of individual error codes. For example:
The message “Err.Sens.02 Stat: 33” includes the error codes 13 and 20. The meaning of the error message is: sensor 02 cannot be initialised and will not be read.
If the failure persists after restarting, the sensor causing the failure can be detected using the menu “Sensor values”:
Start menu “Sensor values”, select one sensor after another:
The circuit is broken between sensors when sensor status switches from 01 to 02:
E.g.: Sensor 01: Status 01
Sensor 02: Status 01
Sensor 03: Status 01
Sensor 04: Status 02
The circuit is broken here between sensor 03 and sensor 04. Check wiring.
