•
When the ignition module reads 1.0 micro amps DC current through the
ground wire the coil to the main gas valve is energized
•
The pilot flame lights the main burner.
•
If the module does not read 1.0 micro amps DC in 90 seconds it will shut
down the main burner and make one more try before locking out.
5.
The water in the boiler is heated to steam.
•
As steam is generated and pressure builds the air is pushed out through the steamtrap
on the lower steam manifold.
•
Steam goes through the steam trap heating it to 192 degrees closing the steam trap.
6.
Pressure builds in the boiler to the set point of 8-10 PSI.
•
The operating pressure switch opens and the heat circuit is de-energized.
7.
With the timed/manual switch in the timed position and time on the timer.
•
115 VAC is sent to the steam solenoid and steam is sent to the cooking cabinet. There
the steam is directed around the product.
•
115 VAC is sent to the “Pause” or “Sure Cook” light.
•
115 VAC is sent to the normally open contacts of the compartment thermostat.
•
The normally open contacts of the compartment thermostat close when the
compartment temperature reaches 193 degrees
•
115 VAC is sent to the timer motor and the timer begins to count down.
•
115 VAC is sent to the condensate solenoid and cold water is sent to the condensate
spray nozzle pulling the steam down the drain.
•
When the steam pressure drops below the operating set point the heat circuit is
energized and the heat process begins again.
8.
Water continues to fill the boiler until the operational water float is lifted and closes, shorting
the HI terminal on the water level board to the C terminal. .
•
When the HI terminal is shorted to the C terminal the WF terminal on the water level
board is de-energized.
•
If the water level drops below the operational water float switch for more than 5
seconds the WF terminal is energized and the water fill circuit begins again.
9.
When the mechanical timer counts down:
•
115 VAC is removed from the condensate circuit.
•
115 VAC is removed from the steam solenoid.
•
115 VAC is sent to the 3-second timer
•
115 VAC is sent from the 3-second timer to the buzzer for 3 seconds.
10.
With the timed/manual switch in the Manual position
•
115 VAC is sent to the steam solenoid and steam is sent to the cooking cabinet. There
the steam is directed around the product.
•
115 VAC is sent to the “Pause” or “Sure Cook” light.
•
115 VAC is sent to the normally open contacts of the compartment thermostat.
•
The normally open contacts of the compartment thermostat close when the
compartment temperature reaches 193 degrees
