THE CONVECTION CIRCUIT

47

The Convection Circuit provides the high-temperature airflow required to brown and cook food items.

CONVECTION CIRCUIT COMPONENTS

The following is a description of each component within the Convection Circuit and how each acts within the circuit. Figure 37 below shows a block dia- gram of the Convection Circuit.

Main Convection Heater

The main convection heater is an open-coil style heater rated at 3300 watts at 208 VAC with a resist- ance of 13.11 Ohms. The convection heater

is controlled by the K4 solid state relay.

Motor Controller (BMSC)

The motor controller is proprietary and will only operate the convection motor described above. The motor controller is controlled on command from the I/O control board and a 0-10VDC speed command from the I/O control board.

High Limit Thermostat

The high limit thermostat is a 250 VAC, 3-pole, manual reset thermostat with a trip point of 572ºF (300ºC). The thermostat, which interrupts power to both the main convection heater and the IR element, should never operate during normal oven operation.

Convection Motor

The convection motor is a brushless AC switch reluc- tance type. Its top speed is 7100 RPM at 1 HP. The motor is controlled by a proprietary controller.
