The new Profile Induction freestanding slide in range has:

•Innovative technology – delivers the responsiveness of gas cooking

•Superior performance – Induction technology heats only the pan and its contents

•Remarkable versatility – This induction cooktop offers the choice of 19 different

power levels, including a 3700-watt, 11 inch element for larger cookware.

•Cooler cooktop surface – Since there is not a traditional thermal heating element,

the induction cooktop stays cooler than conventional radiant cooktop

Induction – A “game changing” technology

for cooking with many features valued by

consumers

Induction Summary


9/29/2011

1. Electronics power a coil under the cooktop

that produces a high-frequency

electromagnetic field.

2. The EM field interacts with ferrous metal

cookware & sets up a circulating electric

current, which generates heat.

3. The heat generated in the cookware is

transferred to the cookware’s contents.

4. Nothing outside the cookware is affected by

the field. As soon as the cookware is

removed from the element, or the element is

turned off, heat generation stops.

Induction Cooking – How It Works


9/29/2011

• Ferro”magnetic” cookware - required

• Glass cooktop

• Flat Coil – usually coated (rope like-multi-

strand wire) – to reduce losses at high

frequency.

• Ferrite Cores to reduce air gap losses.

Induction Cooking - System


9/29/2011

• Cooking Performance: Powerful, commercial type performance

• Versatility: Responsiveness & control similar to gas

• Efficiency: Energy transfers direct to cookware

• Cleanability: Easy-to-clean & wipe-off

• Surface Temperatures: Cooktop remains cool

Clad Cookware Lodge Ware –- enameled cast iron

To test cookware - use a magnet if a magnet clings to the base of the cookware it is induction ready.

Consumer can use a refrigerator magnet to verify.

Important Note: Boost Mode and Power Sharing

The induction coils on the left side are paired for power sharing and both

cannot be used simultaneously on “H”. The last coil set to “H” will remain

on “H” and the other coil will reduce to power level “71/2”. The induction

coils on the right side are likewise paired for power sharing. The last coil

set to “H” will remain on “H” and the other coil will reduce accordingly (RF

coil will reduce to “7” and the RR coil will shut off).

Power Sharing


9/29/2011

Slight sounds may be produced by different types of cookware. Heavier pans such as enameled cast iron produce less noise than a lighter weight multi-ply stainless steel pan. The size of the pan, & the amount of contents, can also contribute to the sound level.

When using adjacent elements that are set at certain power level settings, magnetic fields may interact & produce a low whistle or intermittent “hum”. These noises can be eliminated by raising or lowering the power level settings. Pans that completely cover the element will produce less noise. A low humming noise is normal particularly on high settings.

Stand By – Line voltage is applied. No cooking zones are activated. No displays are illuminated with the exceptions of “hot zone” indicators, or timer count down in progress.

Ready - The cooktop main power is turned on & awaiting a function key press.

In Use – At least one of the cooking zones is in use.

Locked – All displays are off with the exception of the “Control Lockout” pad. No functions available until the unlocked sequence is done (press & hold the control lockout pad for 3 seconds to lock & unlock cooktop).

Control Panel Assembly


9/29/2011

There are four induction cooktop coils.

The controls for the cooktop module

consist of two burner Touch Boards

connected to and working through the

main logic board. The main logic board is

connected via the Linbus serial wire to

the cooktop module, DRM board, bridge

board and the RPSM. (Relay Power

Supply Module) located on the back of

the range.

The bridge board contains the surface on/

hot cooktop indicator lights. The induction

module cooling fan connection is also

located on this board. The bridge board

bridges the Linbus connections from the

filter board, main logic board along with

the RPSM.

A Fifth cooktop element is a resistive

warmer controlled by the DRM relays.

See wiring diagrams. No relay boards or

line voltages are brought to the control

panel.

If the zone ON/OFF key is pressed, but no UP (+) or Down (-) keys are pressed for a period of 5 seconds, then the control will revert back to “Ready” or “Active” mode with out activating the element. If the control was in the “In Use” mode, the control digit display will turn off. After the on/off key is pressed, one touch of the + or – will start the power level at 5 for all induction elements and will increase by ½ increments from L,1,2,3,4,5,6,7,8,9,H.

If the +/- buttons are pressed & held for a period of 2 seconds, the control will automatically increase or decrease the displayed power level at a rapid rate.

9/29/2011

• A capacitive touch switch consists of two conductive layers on opposite

sides of an insulating material such as glass.

• The touch switch has conductive layers, which create a capacitance that

decreases when a layer is touched by a human finger, for example.

• Interface circuitry is used on a touch switch to convert the capacitance

change into a usable switching action to drive logic systems or to switch

analog signals.
