ELECTRICAL OPERATION

COMPONENT FUNCTION

Power Switch (S1)	Determines the mode of operation; ON, OFF, or COOL DOWN.
Oven Light Switch (S2)	Controls the oven cavity lights.
Fan Speed Switch (S3)	Controls blower motor speed between High and Low settings (VC4ES/6ES
	and VC4ED/6ED only).
Alarm/Buzzer	Signals the end of a "Cook" cycle when cooking time expires.
Cook Timer	Counts the "Cook" time of the product and signals the buzzer at the end of
	the cycle (VC4ES/6ES and VC4ED/6ED only).
Door Switch	Allows the oven to operate when the doors are closed but stops the oven
	from operating when the doors are opened.
Blower Motor	Operates the oven cavity blower (convection fan).
Transformer (T1)	Provides 24VAC power to the Computer Control (VC4EC/6EC only).
Transformer (T2)	Provides 240VAC power to the oven control circuit and blower motor
Solid State temperature	(480VAC models only).
Control	Monitors temperature sensor and regulates the oven cavity temperature by
	controlling 2CON to energize the heating elements when the control calls
	for heat.
High Limit Thermostat	Protects the oven from temperatures above 550°F by removing power
	from the heating circuit. Auto resets at 500°F.
Computer Control	Monitors temperature sensor and regulates the oven cavity temperature by
	controlling 2CON to energize the heating elements when the control calls
	for heat. Also, counts the "Cook" time (normal cooking) of the product and
	signals the electronic alarm at the end of the cycle. If "Cook" & "Hold"
	mode is selected, when the "Cook" (then hold) time expires, the oven
	heating stops and the oven enters "Hold" mode. Once the oven cavity
	temperature drops to 150°F, the heat comes back on and the oven cycles
	at this temperature to hold the cooked product. Cook & Hold is standard on
	computer models. The selected mode also determines the fixed blower
	speed of High for "Cook" and Low for "Cook & Hold".
SSR1 & SSR2	When SSR1 is energized by computer control, connects power to blower
	motor for High fan speed operation in normal "Cook" mode. In "Cook &
	Hold" Mode only, SSR1 is de-energized and SSR2 is energized by
	computer control and connects power to blower motor for Low fan speed
	operation (VC4EC/6EC only).
1CON & 2CON	Provides power to heating elements when both are energized. 1CON is
	energized when power switch is turned ON. 2CON is energized by the
	temperature control when a call for heat is made.
Power ON Light	Lit whenever the power switch (S1) is turned to ON or Cool Down mode.
Heat Light	Lit whenever temperature control is calling for heat.
