C24GA SERIES CONVECTION STEAMERS - ELECTRICAL OPERATION

1.Turn power switch on.

A.Timer de-energized.

1)Operating voltage applied to control compartment after cavity relay is latched on.

B.Water level control (WLC) energized.

1)Low level (LL) relay N.C. contacts provide operating voltage to fast-fill solenoid.

a.Fast-fill solenoid energized, water begins filling the generator.

2)Water reaches low level probe.

a.LL relay N.C. contacts open and N.O. contacts close.

b.Voltage applied to normally closed pressure switch (opens at 4.0 psi).

c.Voltage applied through HL contacts to hold thermostat (closes at 190°F).

d.Voltage through pressure switch applied to blower and to normally open air switch (closes at

0.4" W.C.).

e.Fast-fill solenoid de-energized.

C.Air switch closes at 0.4" W.C.

1)Voltage applied to step-down transformer primary (120 VAC). Transformer steps voltage down to 24 VAC to operate ignition module.

2)Voltage applied to PV terminal of gas valve and applying voltage to pilot valve and high voltage spark lead to ignite pilot.

3)Flame sensor sends signal to MV relay. 1 micro-amp or higher is required to maintain pilot.

4)MV relay contacts close and energizes main valve.

5)Main burner ignites.

D.When temperature reaches 190°F, hold thermostat closes energizing the slow-fill solenoid to keep generator full.

E.When generator pressure reaches 4 psi, the pressure switch N.C. contacts open, the N.O. contacts close.

1)Voltage is removed from:

a.Air pressure switch.

b.Blower motor.

c.Step-down transformer which removesvoltage from ignition module.

F.Voltage through the N.O. contacts of the pressure switch is applied to the cavity relay in the compartments.

1)Voltage applied to compartment controls after cavity relay is energized. Relay remains energized until main power is removed.

Compartment control (Units before Dec. 1, 2005) Refer to schematic diagrams 00855693 & 00855424.

1.Compartment door closed causing door switch to close and READY light to illuminate.

A.120 VAC applied through door switch to timer contact 1.

B.Timer manually set to desired time period.

C.Voltage applied through contacts 1 and 3.

1)Timer begins countdown.

2)Steam solenoid energized allowing steam into compartment.

3)Cavity relay 1 energized, energizing the CWC solenoid.

4)Cook Light illuminated.

D.Timer times out.

1)Timer contacts 1 – 3 open turning off steam solenoid and cook light.

2)Timer contacts 1 – 4 close, turning on buzzer.

E.Buzzer manually shut off by rotating timer to off position.

2.Power switch set to off position.

A.Power removed from compartment controls and generator control circuit.

B.Time delay relay energized.

1)Delay relay starts 1000-second countdown.

2)Drain solenoid energized for 1000 seconds.

3)Water drained from generator.
