Admits cold water to the cavity drain and mixes with the hot to condense steam and cool the drain water before entering the floor drain. This solenoid valve is energized whenever the steam generator heating elements are energized. Does not operate during a drain cycle.

Admits water to the steam generator when requested by to oven control, to fill or replenish the steam generator water level.

Signals the oven control that door is closed and can be locked.

Allows door motor to operate to unlock door.

Allows door motor to operate to lock door.

Allows door motor to operate to lock door (20 Level only).

Allows door motor to operate to unlock door (20 Level only).

Signals the oven control, that the vent is opened or closed.

Removes power from board relays K6, K7, K8, K9 & K10 if oven cavity temperature rises above 650°F. Must be reset manually.

1TF & 2TF Thermal Fuses

Removes power from KM1, KM2, KM3 & KM6 (6 level); KM1, KM2, KM3,

 

KM6 & KM7 (10 level) and KM1, KM2, KM3, KM5, KM6 & KM7 (20 level

 

half and full) if steam generator temperature rises above 243°F.

3TF Thermal Fuse

Removes power from KM1, KM2, KM3, KM5, KM6 & KM7 (20 level half

 

only) if steam generator temperature rises above 243°F.

4TF Thermal Fuse

Removes power from KM1, KM2, KM3, KM5, KM6 & KM7 (20 level full

 

only) if steam generator temperature rises above 243°F.

1TB Terminal Block

Incoming voltage supply connection.

1T Power Supply Board

 

& Transformer

Supplies 12VAC for cavity light; 24VAC to relay board and oven control

 

board; 230VAC or 90VAC to cavity fan motor(s) at full or half speed; and

 

230VAC to all other electrical controls except heaters.

Water Level Sensors

Senses the water level in the steam generator and signals the oven

 

control to energize or de-energize the fill solenoid valve. The water fills

 

until the circuit between the two sensors is completed plus an additional

 

0.5 seconds. With the water at the proper level, if a call for heat is made

 

from the oven control, the steam generator heating elements turn on until

 

the cavity temperature is satisfied then turn off. When the water level

 

falls, the circuit opens and the fill cycle repeats. If the circuit remains

 

open longer that three seconds, the heating elements are de-energized

 

until the level rises to complete the circuit.

KM1 (1CON)

Contactor for half power full speed (1500 RPM) cavity fan motor(s).

 

When energized along with KM2, provides full power and full speed

 

(contactors KM1 + KM2 energized). When half power half speed mode is

 

selected, contactor KM1 is energized only.

KM2 (2CON) . . . . . . . . . . . . . . . . .

KM3 (3CON) . . . . . . . . . . . . . . . . .

Contactor for half power half speed (800 RPM) cavity fan motor(s). When energized along with KM1, provides full power and full speed (contactors KM1 + KM2 energized). When half power half speed mode is selected, contactor KM2 is not energized.

Contactor for steam generator heating elements; (2HTR) on 6 level; (2HTR) and (4HTR) on 10 level; (2HTR) and (4HTR) on 20 level half.
