| | 6 | "Probe cannot determine the filling level." « Product and water level are set to "0" by the control unit, the temperature is continuously transferred. | The permanent display of this status indicates a defective probe. « The probe must be replaced. | |
| | 7 | "Reduced measuring accuracy." « All measuring data are continuously processed, however, a reduced measuring accuracy must be considered. | The status is actuated when the probe is exposed to significant liquid fluctuations, which prevents accurate measurement. This may be the case, when the tank is refilled. « No action required. | |
| | 10 | Data transfer error. « Product and water level as well as temperature are not registered and set to "0" by the control unit. | This status is actuated when the control unit detects (by check sum) a faulty data set transferred by the probe. Possible causes: Connection problems, loose contact in/on the cable, extreme electromagnetic radiation. « Check the contacts of the cables and the cable installation (according to EMC). « Check if all electrical devices installed in the vicinity correspond with the current state of the EMC regulatations. | |
