54 1.29 Fault codes Display Fault Response of the cooker if a fault occurs Er 0 Incorrect module combination Following a main reset, the control and power module identifies the model of the operating and installed display board. If the two modules do not belong together, the display module outputs this fault Er 1 Er 2 Er 3 Er 4 Temperature sensor PT500 interrupted (e.g. not connected or cable break) Incorrect mains connection (400 V instead of 230 V) Electronics module is overheating (temperature on printed circuit boards above 85 C) Temperature sensor PT500 shortcircuited code. The cooker can no longer be controlled and cannot be operated. An interruption in the temperature measurement corresponds to a very high temperature in the analysis. When the maximum value is determined, this fault code occurs. This fault is detected within 10 sec. The cooker is not heating. The fans switch on. After correctly measuring the temperature at least twice, the fault is deleted again and the cooker continues heating. No consumers are switched on. If printed circuit board temperatures measured on the electronics module are above the stored temperature limit value, the cooker switches the heaters off and the fans switch to fan run-on. When the temperature has dropped by more than 5 K below the limit value, the fault display is deleted and the appliance can heat up again. A short-circuit in the temperature measurement corresponds to a very low temperature in the analysis. When the minimum value is determined, this fault code occurs. This fault is detected within 10 sec. The cooker is not heating. After correctly measuring the temperature repeatedly, the fault is deleted again and the cooker continues heating. Er 5 Communications fault No communication can be established between E3minus or the display and control module. The modules then actuate a reset in the other module in order to re-establish communication. Er 6 Oven does not lock (e.g. defecting locking unit) If the oven door is not locked even after the specified number of attempts, the locking process is terminated. Pyrolysis can no longer be operated. Er 7 Oven does not unlock (e.g. defecting locking unit) If the oven door is still locked even after the specified number of attempts, the unlocking process is terminated. The oven can no longer be operated. Er 9 Error during ROM check Following a reset the controllers implement a ROM check. If a fault is detected, all heaters switch off. Er 10 Error during DataFlash check Following a reset the controllers implement a DataFlash or PROM check. This check does not include the whole memory but only the area relevant to the control parameters. If a fault occurs, all heaters switch off. The fans continue running as in fan run-on. 157_ _ARA_EN_D.doc Seite 54 von 62

55 Display Fault Response of the cooker if a fault occurs Er 11 A button is actuated continuously After a button has been actuated continuously for xx seconds, this fault code is generated. The button is then no longer functional. When the continuous actuation has been eliminated, the fault code is deleted and the button is functional again. Er 12 Defective temperature sensor on the electronics module This fault is not displayed! All functions which revert to the electronics module temperature run as if the temperature were low. Er 13 Power too high If the power of the heating elements to be actuated is higher than the stored maximum power which may be actuated, this fault code is indicated. The heating process is terminated. Following correct power measurement, the fault is cleared and the cooker continues heating up. The entire function has been designed exclusively as an aid for development phase and testing and may no longer actually occur in the field. Er 14 Plausibility check If data to be used for control is outside the defined range, this fault code is displayed. The heating process is terminated. After the type of heating has been changed, the fault is deleted and the cooker can heat up again. Er 15 Cooker too hot If the actual temperature is above 380 C, the heating elements switch off and the oven is locked. The oven door does not unlock until the temperature drops below 300 C again. (This fault does not occur if Pyrolysis runs correctly). 157_ _ARA_EN_D.doc Seite 55 von 62
