B. Component Function

1. Oven Controller

The controller controls all functions of the oven. The cooking temperatures can be set from 200F

to 900F (93C to 509C). Cooking times (conveyor speed) can be set from 1:00 minute to 60:00

minutes on the DZ33I.

Controller features a self-cleaning mode, an energy conserving standby mode, and also included

is a service mode designed to assist the service technician.

The Menu Select control contains 10 menu keys which can be preset to control both oven

temperature and cook time. The operator must then press only the menu key for the desired

product being cooked.

2. Infrared Heating Panels

Heating panels are positioned above and below the conveyor belt in the oven chamber

(figure 1-3). When energized these panels emit infrared long waves. These waves do not heat the

air through which they pass. Instead the waves are absorbed by the outer surface of the product

transported through the oven on the conveyor belt. Using this application, food is placed on the

conveyor and the unique properties of the infrared waves cause it to cook from the outside to the

center in traditional fashion.

DZ33I Heat Zones

3. Conveyor

The conveyor is used to convey the product through the oven deck (chamber). The conveyor is

made up of 1 to 2 stainless steel wire belts which can travel in either direction around the frame.

The conveyor is controlled by the controller and can travel at speeds from 1:00 to 60:00 minutes.

The speed of the conveyor determines how long the product will be in the cooking chamber which

is the cooking time.

CAUTION: All DZ ovens are Voltage Specific. Check the oven data plate for the voltage. Applying the wrong voltage can

immediately damage the oven. Refer to the Installation Section of this manual for complete instructions before installing

an oven.
