achieved before the timer motor begins to "time out." When the timer motor has operated for the

preset duration, the common element is transferred to contact (4), returning the inlet solenoid valve to

the closed position and energizing the buzzer. Contact to the buzzer circuit remains closed until the dial

is manually turned to the OFF position, returning the common element (1) of the timer switch to the

neutral position.

Indicator Lights

An indicator light is included for both compartments. The light remains on (red) at all times when the

coinciding timer dial is set and the door interlock switch is closed. The light turns off at the end of the

timed cooking duration or when the set time has elapsed.

The buzzer is an alarm device that operates by oscillation of a striker against the core of an

electromagnet. When the 60-minute timer dials reach the "0-Minute" position, the buzzer coil is

energized to sound the buzzer. Movement of the timer dial to the OFF position opens the contact to the

buzzer coil to shut it off.

The interlock switch is a single-pole proximity switch with normally open contacts. The switch is

operated by the proximity of a magnet within the door. When the door is open, the switch contacts

remain in the open position. When the door is closed and securely latched in place, the magnet is near

the switch to close the contacts.

Connected between the operating contact (3) of the timers and the steam inlet solenoid valve, the door

switch acts as a protective device to interrupt valve operation unless the door is closed.

The thermostatically operated switch is a two-position, normally open switch mounted on the cooking

compartment. The switch functions to activate the cold water solenoid valves of the steam condensing

system and to delay timer motor operation until the compartment temperature reaches 195°F, thus

assuring that cooking temperature exists throughout the timed duration.

The timer controls the steam to the cavity by either a constant steam setting or a used defined timer

that will be programmed by the user into the timer

The Kettle Switch will allow the user to set the mode of the steam. The user can either set the switch so

that top and bottom cavity are in use at the same time. Or the bottom cavity and a separate direct

connected kettle can be used at the same time.
