PRINCIPLES OF INDUCTION

Introduction

There are two techniques of glass-ceramic heating:

• Infrared.

• Induction.

The difference is only obvious once the cooking zones are turned on. The Infrared one glows red while the the induction doesn’t seem to operate. The Infrared is provided with radiant or halogen sources that transmit heat by radiation or conduction. Induction Cooktops produce a magnetic field which passes through the glass ceramic to the pan. When ferro magnetic cookware is used, this magnetic field excites the molecules in the pan, causing them to vibrate at a very high frequencies, producing heat.

The principles of heating by induction is a natural phenomenon discovered in the 19th century by several physicists, among whom a certain Leön Foucault. He highlighted the development of currents facing the magnetic field in a moving metallic mass or a fixed metallic mass run though by a variable magnetic flux. These eddy currents comparable to short-circuits cause a heating effect (Joule effect) in the mass.

The operating principle is innovating. Contrary to other cooking modes, it is the container itself, which heats and not the cooking surface. This results in a very responsive method of cooking.

You put a saucepan on the cooking zone that is sufficient to initiate the heat while the cooking surface remains cool. the heating element is nothing but the container metal, which transforms the magnetic energy into thermal energy.

Induction qualities are flexibility, low inertia, easy cleaning, good efficiency and thermal safety. Induction efficiency may reach up to 90% according to the types of cooking. With such a technique, the container only heats. Inertia is therefore low, and above all, the plate stepping from the mildest temperature to the strongest power, in an instant and while diffusing heating a homogeneous way, attracts more and more consumers.

Operation Information

PRINCIPLES OF INDUCTION

Operational Principles

An induction cooktop operates thanks to the electromagnetic properties of most containers used on the traditional cooktop.

At a first approximation, you can compare this cooktop with a transformer of which the secondary winding would have been shorted. A significant internal current arises therein and causes quick heating.

The saucepan can be compared with a shorted set of concentric whose internal resistance is not zero.

From the function keys, you can control the electrical power supply to the transformer primary winding that generates a magnetic field. This field induces currents at the bottom of the container placed on the cooking zone. These induced currents heat immediately the container, which transmits the produced heat to the food contained inside. Cooking is performed practically without any loss of energy. The appliance heating power is pushed to its maximum.

INDUCTION COOKTOP OPERATION

Control Operation

The Wolf Induction cooktop operates by automatically cycling the heating elements between zero power and full power. As the heat is increased on the control panel, the element will stay on at full power for longer periods and the element will have shorter periods of zero power.

Residual Heat Indicators

As an added safety precaution, residual heat indicator lights will illuminate when the surface temperature of the glass is above 150°F. Each heating element has an independently controlled light located to the right of that element. Even if the cooktop controls are turned off, the indicator light(s) will illuminate to show the user that the cooktop surface remains hot.

Modes of Operation

Lock Mode: All keypad operation on the control panel is disabled and all of the heating elements are de-energized. A steady glowing light within the "key" symbol indicates the unit is locked.

• To unlock the control, touch and hold the "key" symbol for 3 seconds. The unit will beep twice and the light with-in the "key" symbol will go out. The control unit is now in the idle mode. (See Figure 3-4).

• To lock the control, touch and hold the "key" symbol for three seconds. The unit will beep three times and the light within the "key" symbol will illuminate. (See Figure 3-4).

NOTE: When the unit is powered up for the first time or if there was a power outage, the unit will default to this

mode.

Idle Mode: After unlocking the control panel as described in Lock Mode, the unit enters the idle mode of operation. The only valid keypad operations are the "OFF /ON" for each element and the "key" symbol.

Front Element Operation

To activate a heating element, you must first touch the corresponding "OFF/ON" area of the desired element. The power indicator bar graph will begin to blink and show a half power status. To complete the activation of heating element, you must do one of the following while the bar graph is still blinking:

• Touch "+" symbol of the element control to complete the activation and set the power output one indicator light above half mark.

• Touch "-" symbol of the element control to complete the activation and set the power output one indicator light below half mark.

• Touch "HIGH" symbol of the element control to complete the activation and set the power output to full power.

• Touch "MELT" symbol of the element control to complete the activation and set the power output to the lowest

power.

NOTE: Power indicator bar graph continues to blink until cookware is placed on the corresponding element or if

cookware is removed from the element. If no cookware is placed on the heating element for 30 seconds, the element will automatically shut off.

To change power level setting, once the unit is activated and the bar graph lights remain steady on:

• Touch “+” to increase the power level by one light on the bar graph.

• Touch “-” to decrease the power level directly to full power.

• Touch "HIGH" to increase power level directly to full power.

• Touch“MELT” to decrease power level directly to minimum.

• Touch “OFF/ON” to turn the element off.

Rear Element Operation

• Turn on and activate element as described above.

• Touch “HI POWER” to boost the rear element wattage output from 1800W maximum to 2200W maximum. Indicator light under “HI POWER” touch pad will be illuminated.

NOTE: When “HI POWER” is active, the front element will

be limited to 600W maximum output.

• Touch “HI POWER” again to de-activate “HI POWER” mode. The light under “HI POWER” touch pad will go out.

Universal OFF Key

In an emergency situation where there is a need to turn off all heating elements, use the universal “OFF” touch pad to turn the entire unit off. (See Figure 3-5).

COOKWARE SELECTION:

Glass, Aluminum, Copper, Non-Magnetic Stainless Steel

NOTE: Refer to “USE & CARE INFORMATION” booklet supplied with the product for further information on cook-

ware selection.

Pan Test:

Place your pan on a zone. With the selected zone turned on the display will not flash if the pan is compatible. If the display flashes then you cannot use the pan for Induction Cooking.

NOTE: You can also test the pans compatibility with a magnet. If the magnet sticks to the bottom of the pan it is

compatible for Induction cooking.

Pan Compatible with Induction:

• Pans made of enamel coated steel with or without a non-stick coating.

• Cast iron pans with or without enamel coated base.

NOTE: Enamel coated base will prevent the glass top of your cooking surface from scratches.

• Stainless steel pans designed for induction cooking.

NOTE: Stainless steel pans are suitable for induction cooking if they pass the pan test.

• Aluminum pans with special base.

NOTE: Pans which do not have a flat base may be suitable, however they must not be deformed too badly.

• Choose a pan marked with the logo on its base or packaging to be sure that it is perfectly suitable for use on your induction cooktop under normal conditions of use. (See Photo 3-1)

Photo 3-1. Induction Logo

SPECIAL CONSIDERATIONS:

• Glass, ceramic, earthenware pans, aluminum pans (Without special base) and copper pans, and some non-magnetic stainless steel pans are incompatible with induction cooking. You will be informed by the flashing display.

• For uniform cooking, use of a pan that has a thick flat base is best due to it distribution of heat.

Generator Removal

First, extract screws securing baffle, located at the front of generator, and remove. (See Figure 4.11).

Next, extract screws securing left front, left rear and right rear burner mounting brackets and remove. (See

Figure 4.12 and 4.13).

NOTE:Care must be taken when removing right rear

burner mounting bracket due to wiring in this location.

Remove two rear screws that secure generator to burner box. (See Figure 4.14).

Remove ground screw located at rear left side of generator and disconnect L1 and Neutral leads. (See Figure

4.15).

Next, lift rear locking clips on generator and slide generator assembly towards front of burner box, then lift to remove generator. (See Figure 4.16).

NOTE:Generator must be moved forward enough to

allow tabs securing generator to burner pan allowing proper room for removal. (See Figure 4.17).

DIAGNOSTIC MODE

Diagnostic mode allows the Service Technician to determine the cause of the failure. In diagnostic mode only the last error code is displayed.

To initiate diagnostic mode, the unit must to be in the “LOCK” mode. Then, press and hold the universal “OFF” keypad for 5 seconds. The cooktop controls will now enter into diagnostic Mode.

In diagnostics mode, zone LED bars will illuminate and display the last error code logged.

NOTE: If no errors were recorded, no LED’s will be illuminated. Unit will beep, and return to

“OFF” mode.

NOTE: If the “OFF” keypad is not released after 7 seconds, the diagnostic mode will be can-

celled and the unit will return to the “OFF” mode.

NOTE: If any other input signals are detected from the keypad, the unit will not enter diagnostic

mode.

NOTE: When in diagnostic mode all heating units are off.

NOTE: The unit will exit diagnostic mode if no

inputs are detected from the keypad in 20 seconds.

NOTE: If the “OFF” keypad is pressed again

anywhere within the diagnostic program, the unit returns to the “LOCK” mode of operation.

NOTE: There will be no audible signals dur-

ing the diagnostic mode.

INTERPRETING HEX DECIMAL CODE

The zone bar light uses the first four LED’s from the right (LED 16), to left (LED 1), to display the HEX DECIMAL code used to determine the error code. Each LED has a corresponding numeric value that needs to be added together to determine the corresponding error code. (See Figure 5.1)

When the sum of the corresponding numeric value of the illuminated LED totals 10 - 13, then a letter is assigned in placed of that sum.

Example: 10 = A; 11 = B; 12 = C; 13 = D.

NOTE: The troubleshooting guide list the cor-

responding illuminated LED’s. (See Figure 5.2)

NOTE: Error code may appear in either dis-

play or both simultaneously.
