POWER-UP THE OVEN

1. Turn the “On/Off Switch” to the “on” position. The oven will now run according to the previously programmed settings. Allow the oven to preheat for approximately 30 minutes.

Belt speed refers to how quickly the food item travels through the oven. This is shown on the display board as a unit of measure (fast to slow) between 0:30 seconds and 15:00 minutes.

The countertop oven will allow you to determine the temperature setting of the oven. You have the ability to program your oven so that more (or less) heat will emanate from the unit. This is shown on the display board as a unit of measure between 90°F – 600°F.

The countertop oven will allow you to change the direction in which the conveyor belt moves. Pressing the “Belt Direction Button” will change the direction of travel between left-to-right and right-to-left options.

SEQUENCE OF OPERATION

Power Supply

Control Box Auto Cool Down

Main Fan Circuit

Heating Circuit

Oven Control

Conveyor Drive

Electrical Power is supplied to the oven by a three conductor cord set. Black conductor is HOT. White conductor is HOT. Green conductor is ground. Line voltage is supplied through the fuses(F1, F2)and line one(L1) through the manual resettable control box high limit(T1) to the ON/OFF switch, the Cooling Fan Thermostat(T2), the Cool Down Timer(TD), and to the Main Fan Relay(R2).

The cooling fan thermostat is connected to the axial fan that cools the control box. Line two (L2) connects to the other side of the Control Box Cooling Fan motor bypassing the ON/OFF switch. The thermostat closes at 120°F cycling the fan keeping the control box below 120°F

Upon activating the ON/OFF switch, power is supplied to the Cool Down Timer (TD) through the timer (TD) to the Main Fan Relay (R2) through the relay (R2) to power the Main Fan (M1).

When the heating contactor then closes, supplying line voltage to the SSR for the heater. Line voltage is then supplied to the element through the SSR as needed to maintain set point temperature.

Upon closing the ON/OFF switch, the transformer is supplied line voltage and then supplies 24 VAC to the control board and controls the conveyor motor. The control reads the thermocouple and cycles the SSR to the heater to maintain set point temperature. The control board also reads the input from the key pad to make adjustments for cook time and temperature.

The control board transformer’s (XR) secondary supplies 24 VAC to the control board (CNTR). The conveyor control converts AC to DC and DC power is supplied to the conveyor motor (M3). 2-29 VDC is supplied to the motor (M3) through 4 wires (2 sets A+ A- & B+ B-).
