Service Manual EKI Induction hob of the 3rd generation Induction: Preparing hot meals on cold zones Induction hobs are characterised by high efficiency for initial cooking and simmering. If the cooking zones are fitted with a touch control panel, the sensor technology switches the cooking zone on when your finger touches the marking.
Service Manual EKI Comparatively short initial cooking times and high initial cooking efficiency are achieved owing to the energy conversion directly in the saucepan base. The favourable simmering energy consumption, which corresponds to that of conventional cooking systems, is typical of induction hobs.

Service Manual EKI Basic functions Switching the control on and off 4.1.1 General Switching on and off relates here to the function of the main switch buttons as elements which release or block the functions of the other buttons. The control is always supplied with power.
Service Manual EKI Switching a cooking zone off A cooking zone can be switched off in two ways: With the corresponding minus button By pressing the corresponding plus and minus buttons at the same time. When the cooking zone is switched off, the display changes from „0“ to „H“ after 3 seconds if the cooking zone is hot.
Service Manual EKI Power characteristics The parameters for the power characteristics are stored in an EEPROM for each cooking zone. Cooking Nom. power Cooking Cooking Cooking Cooking level zone 1 zone 2 zone 3 zone 4 (Ø 180mm) (Ø 145mm) (Ø...
Service Manual EKI Displays - Optical signals 4.8.1 7-segment displays for cooking zones A display is assigned to each actuator (cooking zone). In addition to the signals for the settings and the heat display, the user is also shown the modes "Saucepan missing", "Cooking zone temperature sensor breakage/short-circuit"...
Service Manual EKI 4.8.4 LED for key-lock function With the control switched on, activation of the key-lock function is displayed by an LED above the key- lock button. Buzzer Each activation of a button which results in a sensible and feasible action is acknowledged by a brief acoustic signal.
Service Manual EKI Safety functions Automatic deactivation of the control The touch control is switched off automatically when after activation the user does not press any more buttons and no cooking zone is in use within 10 seconds; no button is reactivated after deactivation of the last cooking zone still in use. The deactivation time for this is 10 seconds and is displayed by the decimal points flashing;...

Service Manual EKI 5.3.2 Heat sink temperature An NTC sensor which protects the electronic components against overloading is arranged on the heat sink. The following action is taken if the heat sink temperature is to high: At a heat sink temperature > 76°C any active booster function is ended.
Service Manual EKI Operating time limit Each cooking zone has its own operating time limit. This depends on the cooking level set and is reloaded each time the level is changed. Once the operating time limit is reached, the corresponding cooking zone is switched off.
Service Manual EKI Fault messages A fundamental difference is made between two types of fault: Faults which permit further use (fault is limited to cooking zone(s) or module) Faults which do not permit further use (fault has an effect on the entire hob)

Service Manual EKI 7.3.6 [d 51], [d 52] - Mains synchronising pulse A check is made to see whether the mains synchronising pulse for switching the cooking zones on and off arrives at the corresponding module. To this end the relevant mains relay is switched on, then a check is made for 2 seconds to see whether the signal triggers an interrupt.
