SEQUENCE OF OPERATIONS

STEAM CUB

Mechanical Timer

When using these instructions refer to the STEAM CUB wiring schematic.

1. Supply Voltage is sent to the primary of the power transformer.

• 115 VAC is sent from the secondary of the power transformer to the on/off
switch.

2. To turn the unit on, place the 115 VAC switch in the on position.

• 115 VAC is sent to the H terminal of the water board.

• 115 VAC is sent to the normally open contacts (R2B) of the R2 relay.

• 115 VAC is sent to the normally open contacts (R1A) of the R1 relay.

• 115 VAC is sent to the normally open contacts (R3B) of the R3 relay.

3. After water has been placed in the cooking cavity and the probe is grounded the water
board will have 120 VAC at the heat terminal.

• 115 VAC is sent through the normally closed contacts (R3A) of the R3 relay and
the normally closed contacts (R2A) to the door switch.

• If the water level drops below the probe the water board will remove 115 VAC

from the HEAT terminal and send it to the FILL terminal.

• From the FILL terminal 115 VAC is sent to the coil of the R3 relay.

• The R3 relay energizes and the normally closed contacts (R3A) open.

• The normally open contacts (R3B) will close and 115 VAC is sent to the

ADD WATER light and buzzer.

4. With the door closed the door switch is closed and 115 VAC is sent to the
timed/manual switch.

5. In the timed mode and time on the timer, or in the manual mode, 115 VAC is sent
through the thermostat to the coil of the contactor.

• The contactor closes and supply voltage is sent to the elements and the water is

heated to steam.

• When the cabinet reaches 205 degrees the thermostat opens and 115 VAC is

removed from the coil of the contactor and the elements are de-energized.

• When the unit cools the thermostat closes and the steamer heats again.

6. If one of the high limits (located on the heater blocks) opens a potential difference is
placed across the coil of the R1 relay.

• The R1 contacts will close energizing the R2 relay coil.

• The normally open R2B contacts will close latching in the R2 coil.

• The normally closed R2A contacts will open de-energizing the heater contactor.

• The normally open R2A contacts will close energizing the buzzer.

• The buzzer will sound until the unit is turned off.

7. To turn the unit of the rocker switch is depressed and the 115 VAC is removed from
the heat circuit.
