    1 - INTRODUCTION 1.1 - PURPOSE OF THIS MANUAL The purpose of this manual is to provide service engineers with technical information concerning the new magnetic induction hob fitted to free-standing cookers, enabling them to diagnose malfunctions and to repair the appliances.
  • Page 6: General Information

    2 - GENERAL INFORMATION 2.1 - COOKING USING A MAGNETIC INDUCTION HOB In magnetic induction cooking, the heat of the hotplate is transmitted directly to the pan, in very few seconds and using induced current. The hob itself remains relatively cool. The high-power, high-frequency induction current is generated by an electronic circuit connected to a coil, and generates heat that is transmitted directly to the pan.
  • Page 7: Pan Detection System

    2.2 - PAN DETECTION SYSTEM The circuit that generates the magnetic field also checks the impedance of the "load" (i.e. the pan). The difference in impedance between one pan and another depends on the magnetic properties of the metal and the dimensions of the pan.

    2.4 - DIMENSIONS OF PAN FOR MAGNETIC INDUCTION COOKING For correct operation of the magnetic induction hob, the diameter of the pan must be suitable for the size of the hotplate. Fig. 4 shows a pan that is ideal for the size of the hotplate. CORRECT SIZE FOR HOTPLATE Fig.

    3 - DESCRIPTION OF THE SYSTEM This magnetic induction hob consists of a "Tiger" power module with two generators The module comprises two coils (one for each cooking zone), and is controlled by a COLIBRÌ control unit board (see block circuit diagram below). The main components of the magnetic induction generating system are as follows: Power board, installed inside a generator module known as "TIGER"...

    3.2.1 - JUMPER FOR CONFIGURATION OF GENERATOR MODULE The TIGER generation module is also designed to power the COLIBRÌ control unit board. In order to enable this function, it is necessary to install a jumper across connectors BC1 and BC5 (see fig. 12). In this way, the module powers the control unit via the connector between the control unit and the power board (BC3).

  • Page 15: Ntc Temperature Control Of Cooking Zones (Hotplates)

    3.4 - NTC TEMPERATURE CONTROL OF COOKING ZONES (HOTPLATES) The temperature of each zone is measured by an NTC sensor positioned between the coils and the ceramic glass top (see fig. 16 and 17). In this way, the hob is protected against excessively high temperatures. If one of the zones is found to overheat: If the temperature is in excess of 190°C the power is reduced to 0 If the temperature rises above 200°C the generator module switches off and an alarm sounds...
  • Page 16: Cooking Zones (Hotplates) And Pan Detection System

    3.6 - COOKING ZONES (HOTPLATES) AND PAN DETECTION SYSTEM The system detects the presence of a pan by measuring the inductance through the generator coil. The inductance value depends on the diameter, the mass and the type of material used for the pan. To ensure correct operation of the system, it is important to use a pan whose diameter is suitable for that of the cooking zone.

    3.7 - COLIBRI’ CONTROL UNIT This type of control unit features a interface for control of the hotplates via the rotary potentiometer controls. In this application, the control potentiometers are connected to connectors BK01 and BK02. Power board Rotary control Rotary control connectors Programming...
  • Page 18: Control Potentiometers

    3.7.1 - CONTROL POTENTIOMETERS The control potentiometers are used to select a power level by turning the knob clockwise. Each potentiometer transmits a different resistive value to the power board; these resistive values correspond to the various power levels for the hotplate. ANGLE OF ROTATION Fig.
