3 1 SAFETY 1.1 Safety observations Danger! All repairs must be performed by factory technical personnel. All inadequate repairs may cause injury to users. The housing and frame may be subject to voltage in the event of failure. The appliance must be disconnected from the power grid before being disassembled. In its interior, there are parts under high voltage. Always use a circuit breaker if testing while under power is necessary. The ground connection must not exceed standardised values. It is of utmost importance for personal safety and operating the appliance. After any repair, VED 0701 tests must be performed, or specific country rules must be followed. The power supply cord can only be replaced by technical service personnel and using the replacement cable. Special observations for induction appliances! The induction appliances comply with all safety rules and electromagnetic compatibility rules in force. People with pacemakers implanted must abstain from using or repairing this appliance. It is possible that the appliance could interfere with operation of an implant. 1.2 Repair observations Caution! Never try to repair by indiscriminately exchanging components. Proceed systematically, and consider the technical documentation of the appliance. The electronics boards must not be repaired. They must be replaced with original parts. All exceptions are documented separately. Components sensitive to electrostatic discharges: Respect the EGB reference ( General Repair Manual ) Sharp Edges: Use protective gloves!!

4 2 INSTALLATION 2.1 Assembly instructions Single phase connection IMPORTANT! L N 23 0 V Induction cooktops can only be installed over ventilated ovens of brands from the group and over kitchen furniture. In the event that the cooktop is installed over un-ventilated ovens of our brands, or other brands, the cooktop control may reduce the power level and, if applicable, turn off one or more burners that may be operating, thereby showing indication C3 (shut off due to excessive temperature on the radiator) Overview Correct installation in accordance with the installation instructions is a necessary condition for the correct operation and a long service life of the appliance. The installer is liable for all damages due to incorrect installation Connection A single phase connection is made by connecting the ground, phase and neutral terminals in the corresponding places of the plug or jack. In the event that the pin terminal that joins two wires does not fit in the hole of the plug or jack, remove the pin terminal, strip the ends of the wires and twist them together. Two phase connection with a common neutral L1 L2 N 23 0 V 23 0 V The electrical connection of the appliance must be performed by a qualified technician, thereby considering the installation instructions, the connection schematics and all legal provisions that may be applicable in order to prevent personal injury. All induction cooktops come equipped with a power cord. One end is connected to the electronics boards, while the other end has 6 wires grouped in pairs by pin terminals. Depending on the type of connection, one or more of the pin terminals must be eliminated in order to connect correctly.. As regards a two phase connection, the installer must know the voltages supplied by the electrical distribution system of the home. Remove the pin terminal that joins the two lines, strip the ends of the wires, and connect each one to the terminal of the corresponding plug or jack. In distribution systems with a common neutral, the pin can be connected at the corresponding terminal. 206_ _ara_en_c.doc a Seite 4 von 65

5 Connection to two phases with neutrals at a different voltage L1 L2 N1 N V In systems with a differentiated neutral, remove the pin, strip the ends of the wires, and connect them to the corresponding terminals, thereby making the power supply voltage of the appliance 230 VAC. If the appliance is connected erroneously, the guaranty is void. In the event that the appliance is erroneously connected at 400 V, the Touch Control (TC) will show the U400 error on the display, and an alarm tone will sound. The cooktop must be disconnected immediately and the connection checked in order to eliminate the cause of the failure V Characteristics of Induction IV appliances Pay special attention to the cooling inlets and outlets of induction appliances. For installation over an oven as well as over a cabinet, a separation of 20 mm from the wall or the back of the furniture must be left at the rear of the appliance in order to allow correction ventilation. In the event of installation over an oven, a distance of 4 mm between the bottom part of the counter and the top part of the oven front must be respected. Air entry to the cooktop must not be obstructed. If the appliance is installed in an enclosed piece of kitchen furniture, the rear panel must be eliminated in order to provide correct ventilation Installation All indications in the installation manual must be respected. There is additional information in the appliance manual and in the technical documentation. The appliance must not be started up if any damage due to transport is observed. 206_ _ara_en_c.doc a Seite 5 von 65

6 The new generation of Induction IV cooktops improves the installation conditions of the previous generation in the following aspects: It does not require a front air exit for installations without an oven underneath. It allows installation on 20-mm counters with cabinets and ventilated ovens manufactured by FMH (Montañana). It allows installation on 30-mm counters with ventilated ovens not manufactured by FMH, with pyrolitic ovens, 40-cm compact ovens and Nostalgia ovens. The new Induction IV generation is not officially approved for installation with dishwashers. 206_ _ara_en_c.doc a Seite 6 von 65

7 3 OPERATION 3.1 Induction cookware Glass ( Pyrex ) containers. Earthenware pans Overview All pots and pans with a ferromagnetic base are valid for induction. Only containers that have a base where a magnet remains adhered can be used. The induction system does not heat up other kinds of containers, and the power level indicator on the display will blink. The minimum diameter of the container must likewise be taken into account Valid pots and pans Enamelled steel pots and pans. Cast iron pots and pans. Iron pans. Stainless steel pots and pans, as long as they have a special ferromagnetic base for induction Pots and pans not valid for induction Non-ferromagnetic or non-metallic materials. Aluminium pots and pans. Copper pots and pans. Brass pots and pans. Standard stainless pots and pans. 206_ _ara_en_c.doc a Seite 7 von 65

8 3.2 Modification of the YL146/147/... TC alarm tones The user can, in accordance with the instructions for use, connect or disconnect the alarm sounds of the cooktop. The warning or alarm lights are always connected. Step Sound connection or disconnection 1 Connect the main switch of the cooktop. 2 Put all heating elements at level 3. 3 Disconnect the heating elements from right to left. 4 Press the main sensor and hold for more than 5 seconds. 5 After 4 seconds, a beep is heard. 6 The alarm sounds have now been activated or deactivated depending on the previous status. 206_ _ara_en_c.doc a Seite 8 von 65

9 3.3 Minimun Diameter type diameter minimum It is important to point out that we recommend to use the nominal diameters for getting the best cooking result. The minimum diameters are tested with stainless steal discs (type ST-52). Depending on the pot material and construction these values can be different. The nominal power is reduced as the pot diameter is smaller, in order to avoid overheatings, which can damage the pot. 150 mm 90 mm 180 mm 110 mm 210 mm 130 mm 180 mm 280 mm 110 mm 240 mm 280 mm 170 mm 206_ _ara_en_c.doc a Seite 9 von 65

17 4.3 Ind IV Advanced induction Differences and improvements respect Ind IV There are two differences according to the inductors: The more obvious characteristic in Advanced is the hole that has the mica in the center that makes contact between the NTC and the glass panel. In Ind IV, the NTC was hidden behind the mica due to a silicone layer. The number of loops of the inductor has also changed (decrease) in all heaters. View pictures on the right. Improvements: Its temperature is lower than in Ind IV (offers power for more time, i.e. to cook serials of chips, ) The module power functions at higher frequencies, reducing the pots noise when cooking. Due to the contact between the NTC and the glass panel, the meassure of the temperature is better Assembly It is similar to Induction IV. 206_ _ara_en_c.doc a Seite 17 von 65

38 4.11 TouchControl Super Quattro For 3I models Description The TC Super Quattro works by infrared sensors, not by capacitive sensors. The infrared light reboots from the emisor to the user finger. The operation is also different (like a roulette). When touching the center key, each hotplate is selecting. To heat the fourth fold, it is neccesary touch four times the center key. For 4I models 206_ _ara_en_c.doc a Seite 38 von 65

39 Infrared Operation Sensor pressed The Touch sensor is an optical system that works with infrared light. It consists on the following elements: A transmitter, a receiver and a glass with or without printing. The sensor detects when pressing. The infrared light reboots from the user finger to the sensor on the glass. Sensor not pressed If the sensor is not pressed, there is not enough infrared light reflection in the receiver, so it is not detected. When pressing the sensor, the infrared light reboots from the user finger and sends the signal to the receiver. The Touch sensor is activated. The activation depends on: Finger (size, blood, bone,...) Finger position over the sensors Transmition characteristics between the glass and the glass printing 206_ _ara_en_c.doc a Seite 39 von 65

40 Possible problems or peculiarities This kind of TouchControl often calibrates itself to the light levels and/or finger (as the light reflection is different depending on people, size, color,...). For that reason, to an unusual person working with the touchcontrol, the operation could be harder. Two or three times later, the TouchControl calibrates itself. The TouchControl could not work if: 1. There is a lot of solar light and/or incandescent or halogen bulb (3000 luxes). In this case, when connecting the cooktop, appears an failure message consisting on 3 or 4 dashes depending on beeing 3 or 4 induction and rings. This happens only at first. To delete the failure, make a shadow in the touchcontrol with your hand or cloth. 2. There is not sensor cap, the light could go through, to activate the sensor according to the basic levels. Apart of ringing, appears an E or the Er22 failure. Put the appropiate cap to correct the failure. 3. The ceramic glass should wear resin to improve the pass of the light across the glass and not to reboot in the grain of the glass. In case of changing the glass, check if the spare part has resin. This kind of TouchControl could work even if it is wet, as the water is light transmitter. It does not ring. 206_ _ara_en_c.doc a Seite 40 von 65

There are quick instructions and cookbooks in different languages. You can put oil before. The applications results are the same. We have 3 temperature levels for all frying dishes, minimum, medium and maximum. In use instruction we can read: we can only use this Pan. With another Pans the control doen t work. The Pan can overshot In labor they have made a lot of Proofs and the system protects the frying pan. (maximum temperature 250ºC). The problem is the great variety of different pans in the market. 206_ _ara_en_c.doc a Seite 45 von 65

46 The fryingsensor inductor has 2 functions. It functions as normal heater and as automatik cooking: fryingsensor Sensor - /+ normal heater Drawing pan or S automatic cooking. 206_ _ara_en_c.doc a Seite 46 von 65

47 5 FUNCTIONS 5.1 Basic induction principles Overview The use of induction heating in glass-ceramic cooking devices has existed since With this technique, the container is heated directly. Therefore the cooking surface heats up only as a result of the heat transmitted from the container to the glass, which is much lower than in conventional systems. The base of the container is heated by the electric currents that circulate in its base and which are induced by a variable, mediumfrequency magnetic field generated by the inductors located underneath the ceramic glass. Only containers with a base made of ferromagnetic steel or iron can be used with induction cooktops. Containers that cannot be used for induction can be recognised by the magnet test. Even though it is recommendable to use containers that fit the size of the cooking zone, containers of a smaller diameter can be used without causing notable reductions of efficiency. The cooktop control reduces the power delivered to small containers and, if applicable, stops supplying power when the container does not have the minimum required diameter. Direct heating of the container base provides the induction system with very fast heating. Likewise, the system reacts very quickly to power level changes. Induction provides very precise control of the power levels, wherefore it allows delicate recipes to be prepared. A temperature sensor under the glass is used in order to protect the inductor, and it moreover allows detecting that an empty container is being over-heated and stopping the heating process Operation The power inverter transforms the 50 Hz of the power grid into an alternating current with a frequency between 20 and 50 Hz. 206_ _ara_en_c.doc a Seite 47 von 65

48 5.2 Inducción IV Power control The induction electronics incorporates power control in a closed loop that allows keeping the output power equal to the established reference power (shown in the TC description). However, it is possible for the cooktop to supply power below the nominal power in the following cases: Power regulation in accordance with the inductor temperature 100% Potencia Small diameter containers. The power grid voltage is too low (less than 215VAC). After prolonged frying. 30% During intensive use of the cooktop. In the last two cases, the power recovers nominal power as soon as the temperature falls below the established limits. 185ºC 230ºC Temperatura NTC Bobina Power regulation in accordance with the radiator Potencia 100% Power regulation in accordance with the power grid voltage Potencia 100% 80% 30% 115ºC 135ºC Temperatura IGBTs 150V 215V V V Tensión de red 206_ _ara_en_c.doc a Seite 48 von 65

49 5.3 Keep warm function All induction hotplates have the keep warm function. The keep warm function is suitable for melting chocolate or butter or keeping food warm. This only works with pots and pans suitable for use with induction hobs. If the Keep warm function is activated, the hotplate automatically changes to its minimum power setting (level 1.) to keep cookware warm. To activate the hotplate, select the symbol and + simultaneously. The letter C appears in the visual display. To deactivate, touch the symbol or + simultaneously. The letter C disappears in the visual display and the function will have been deactivated. This function replaces the STC function of Ind IV project. 5.4 Fan activation The fan activation has not changed for Advanced models. It is activated at medium speed when the estimated temperature in the IGBT s is 65º, and at high speed when the temperature reaches 85º. To 4I, 3I models, the realy board activated the fun. To other models (2I, 80 cm, 90 cm, dominos, etc.), each board activates its fun. 100% 50% Velocidad 60ºC 65ºC 80ºC 85ºC 5.5 Container detection Temperatura IGBTs All the induction zones incorporate an automatic container detection system included in the induction control. Even though the minimum diameters may vary according to the material, they are found at 50% of the nominal diameter. When a container is considered to be small, the induction control automatically reduces the power delivered in order to adapt to the container. After activating the zone, if a container is not positioned there or if the container is the incorrect type, the display will flash the power level. After 90 seconds, the TC emits an acoustic tone and turns off the cooking zone. When a container is recognised as valid, the power level display remains constant, and the power indicated on the display is supplied. 206_ _ara_en_c.doc a Seite 49 von 65

52 5.7 Autofocus even the new generation of Induction IV Advanced does not get it. The 280cm double zone detects automatically when the diameter of the pan is the same or higher than the exterior hotplate. Thereby, the exterior element is connected. That connection is indicated by a light in the TC. When connecting a small pan to the double zone, two sounds are heard due to the relays conmutation. The second clic corresponds to the electronic reform Ind IV Autofocus (no Advanced) This project had an error in the instuctions book. It indicates that the exterior hotplate was activated when the size of the interior hotplate was exceeded. In theory, depending on the type of the pan, the exterior hotplate activates when the diameter of the pan is 210 mm, but the instructions book says that it is neccesary 280 mm at least to avoid problem with users. In that case, there are some alternatives to offer to users: Change the left Elin. There is a reference in Quickfinder that has a software improvement but it does not activate the double zone when exceeding the interior hotplate. The situation has improved but not solved. (For models with a 8505 fd or later, it is not neccesary change the elin, they have the software improvement). Offer a quaranty enlargement, indicating that there was an instructions book error, and change also the left elin to improve the situation. Give the money back because the appliance has not the characteristics the user expects. There is nothing more to do, 206_ _ara_en_c.doc a Seite 52 von 65

Place the cooktop plate on the counter with the glass side down. Be careful not to damage it. Remove the 12 screws that fasten the frame/glass to the base Position the frame/glass unit with the glass up Assembly of the appliance: Fasten the frame/glass unit to the base using 12 screws. Install the plate on the cooktop, thereby taking care not to damage the installation pins. Attention! The power connections of the inductors are made using a ring lug and a metric thread screw. Tighten the screw until the terminal cannot be turned by hand. If the screw thread becomes stripped, the induction electronics board will be useless. 206_ _ara_en_c.doc a Seite 55 von 65

56 7 FAULT DIAGNOSTICS 7.1 NTC sensor check NTC of the inductors Each one of the inductors uses an NTC sensor for monitoring the operating temperature. The NTC sensor of the inductor is interchangeable. Conductive grease must be used when replacing the NTC in order to favour thermal conduction NTC of the induction module The temperature of the semi-conductor devices is measured by two NTC sensors that protect the electronics from excessive temperatures. These sensors cannot be replaced. 7.2 Coil check 23 54, , , , ,860 The inductor has no operational parts other than the NTC temperature sensor, wherefore it is not usually a source of breakdowns. Nevertheless, the procedure presented below can be followed: The inductor must be checked without power connected. Remove the mica sheet carefully so that it does not become damaged, and perform a visual inspection. Check that there are no burned areas. Check the continuity of the inductor using a tester (<1 ohm). Replace the mica sheet, being careful not to damage it Conversion table of the NTC sensor Do not replace the inductor unless burned zones are observed or there is no electrical conductivity.

End of service program After finishing steps P0, P2, P8 and P9 the TC returns automatically to the stand-by mode. 120 s after not activating any sensor (except during the lifecycle tests of step P8). Step P0: End the service program In this submenu, by pressing any sensor (except the ignition one), the service program is exited and the appliance returns to stand-by mode. Step P1: Check of sensors, buzzer and displays 1. To start the check, press any sensor, except for the ignition one. 2. Wait for two seconds whilst the TC detects the reference values of the sensors. During this process the upper horizontal segments of the displays remain on. 3. When the intermediate horizontal segments of all the displays light up, the verification of the sensors can begin. 4. Individually press each one of the sensors and check the indication on the display: 206_ _ara_en_c.doc a Seite 61 von 65

62 Indication 0 Correct operation Meaning 1 Lack of sensitivity in sensor 2 Sensor too sensitive 3 Outside tolerances 4 Problem in ignition key 9 Simultaneous activation of several sensors After checking all the sensors and if these work correctly, the program goes automatically to the inspection of the buzzer and of the displays. To do so, the buzzer is activated for 2 s and all the segments and LEDs light up for 10 s. Step P2: Return to factory values This submenu permits annulling the changes made by the user, returning the appliance to its factory programming: Erasure of the fictitious residual heat indication H/h Erasure of the data stored in the memory Elimination of the selection buzzer deactivated Elimination of the reduce blockage time function. Deactivation of the child lock The steps to follow to carry out the submenu are: 1. After selecting P2, press any sensor, except the ignition one. 2. A whistling is heard. 3. The display shows o o o o for 2 s as confirmation that all the values have been erased. Step P7: Indication of parameters With this menu it is possible to check the value of different parameters of the induction top. To do so, all the sensors (1,2,3,...) of the Touch control are pressed from left to right, except the ignition one: Sensor Indication Description 1 E.g. S Software version E.g. V E.g. o Current failure counter (400V) 3 E.g. t Maximum temp. of TC 4 E.g Operation hours counter 5 E.g. P Part number 6 E.g. r No. Ignitions counter 7 E.g. E EEPROM Version E.g version Free Step P8: Lifecycle test This submenu permits carrying out lifecycle or durability tests automatically. It is not used in tasks that concern the Technical Service. Step P9: Deactivation of the maximum operation time This step permits deactivating the operation time limitation. The sequence given below must be followed: 206_ _ara_en_c.doc a Seite 62 von 65

63 1. Press any sensor, except for the ignition one, for 3 s. 1 is indicated on all the displays. 2. After the three seconds the key LED lights up and the appliances changes to stand-by mode. 1. Order the new spare part in order to change the old one. In the new modules is avaliable a new safer version of software that protects the appliance against unsuitable pots. The new spare parts are marked with a green sticker 7.8 Mistake elin by pot detection Symptom of defect There is repetitive failure with the left board (ELIN) with spare part number Concerned appliances: 3I Induction IV.
