10. Wiring Diagram and Operating Sequence

10-2 Description of Operating Sequence(Continued)

Initial operating status of Power Relay when the START button is pressed.

Relays are designed to work as shown in the figure below.
When the oven is set to DEFROST power position, Inrush Relay1 and Power Relay1 are

programmed to work with Inrush Relay2 and Power Relay2 not simultaneously but alternately.

NOTE : LAMP: Lamp Relay (250V 5A)

MAIN: Main Relay (250V 16A)
VENT: Ventilation Motor Relay (250V 5A)
IR1: Inrush Relay1 (250V 5A)
IR2: Inrush Relay2 (250V 5A)
P1: Power Relay1 (250V 16A)
P2: Power Relay2 (250V 16A)
