FULL SIZE ELECTRIC CONVECTION OVENS - ELECTRICAL OPERATION
SEQUENCE OF OPERATION
Cook Cycle
1.Conditions.
VC4ES, VC6ES with Mechanical KX Thermostat
Schematic diagram 6532 will be used to explain the electrical sequence of operation.
Cook Cycle
1.Conditions.
A.Oven connected to correct voltage and is properly grounded.
B.Power switch (S1) OFF.
C.Temperature dial set to lowest temperature (fully CCW).
D.High limit thermostat CLOSED.
E.Oven doors closed (door switch contacts CLOSED).
F.Oven cavity temperature below 140°F.
2.Power switch (S1) turned ON.
A.Power ON light (Amber) comes ON.
B.1CON coil energized.
C.Blower motor energized.
NOTE: Motor speed (Hi/Low) depends on position of fan speed switch (S3).
D.Component cooling fan energized.
E.Power to oven cavity light switch (S3) wire #1. Turns cavity lights ON/OFF and does not affect "Cook" cycle.
3.Set thermostat to desired "Cook" temperature and thermostat CLOSES.
A.Heating light (Clear) comes ON.
B.2CON coil energized.
1)Heating elements powered and heating starts.
4.Oven reaches set temperature and thermostat
OPENS.
A.Heat light goes out.
B.2CON coil
1)Power removed from heating elements and heating stops.
5.The oven will continue to cycle on the thermostat until the doors are opened or the power switch (S1) is turned to the OFF or COOL DOWN position.
VC4ED, VC6ED with Solid State Temperature Control
Schematic diagram 6534 will be used to explain the electrical sequence of operation.
A.Oven connected to correct voltage and is properly grounded.
B.Power switch (S1) OFF.
C.Temperature dial set to lowest temperature (fully CCW).
D.High limit thermostat CLOSED.
E.Oven doors closed (door switch contacts CLOSED).
F.Oven cavity temperature below 140°F.
2.Power switch (S1) turned ON.
A.Power ON light (Amber) comes ON.
B.1CON coil energized.
C.Solid state temperature control energized.
1)Heating light (Clear) comes ON.
2)2CON coil energized.
a.Heating elements powered and heating starts.
D.Blower motor energized.
NOTE: Motor speed (Hi/Low) depends on position of fan speed switch (S3).
E.Component cooling fan energized.
F.Power to oven cavity light switch (S3) wire #1. Turns cavity lights ON/OFF; does not affect "Cook" cycle.
3.Set temperature dial to desired "Cook" temperature.
4.Oven reaches set temperature.
A.Temperature control
1)Heat light goes out.
2)2CON coil
a.Power removed from heating elements and heating stops.
5.The oven will continue to cycle on the temperature control until the doors are opened or power switch (S1) is turned to the OFF or COOL DOWN position.
