SEQUENCE OF OPERATIONS
Mechanical Timer
1. Supply power is sent to the primary of the main transformer.
115 VAC is sent from the secondary of the main transformer to the on/off rocker,
2. To turn the unit on, depress the red on/off rocker switch.
115 VAC is sent to the red power light.
115 VAC is sent to normally open drain valve closing it.
115 VAC is sent to H and N on the water level board
3. With the water level board energized and no water in the generator
5 seconds later 115 VAC is sent from the FILL terminal to the fill solenoid.
The fill solenoid opens and the generator fills through the drain valve.
The water fills to the low probe shorting it to ground
115 VAC is sent to the heat standby timer which will energize 3 seconds every 4
minutes to maintain heat while unit is idle
115 VAC is sent from the HEAT terminal to the timed manual switch.
4. When the timed/manual switch is in the timed position and time is on the timer
115 VAC is sent from the timer to the R2 relay coil
R2 relay energizes closing the R2A and R2B contacts
115VAC is sent through the now closed R2B contacts to the timer motor
115 VAC is sent through the now closed R2A contacts through the door switch to the
normally closed contacts of the high limit switch.
115 VAC is then sent through the high limit to the coil of condensate solenoid
The condensate solenoid opens spraying cold water down the compartment drain.
115 VAC is also sent through the high limit to the coil of the contactor.
115 VAC is sent to the clean light timer.
When the clean light timer times down 115 VAC is sent to the clean light switch.
When the clean light switch is depressed the clean light timer is reset.
5. When the contactor coil is energized supply voltage is sent to both of the elements.
The elements are energized and the water is heated to steam.
Steam is directed to the cooking compartment.
6. When the timer times out
115 VAC is sent to the 3 second timer and then to the buzzer for 3 seconds.
115 VAC is removed from the R2 relay.
R2A contacts open de energizing the heat circuit
R22B relay contacts open removing the 115 VAC from the timer motor
7. When the water level reaches the high probe then 115 VAC is removed from the FILL
terminal and the fill solenoid is turned off.
8. After the water level drops below the high probe for 5 seconds 115 VAC is sent to the FILL
terminal again.
9. The red on/off switch is depressed and the unit is turned off.
115 VAC is removed from the heat and timer circuit.
115 VAC is removed from the normally open drain valve allowing the steamer to drain.
115 VAC is sent to the 3-minute timer and the fill solenoid is energized for 3 minutes
flushing the drain.
