Cleveland Range OGB-10.10 a The front display will include a lighted bar under the steam symbol

aThe front display will include a lighted bar under the steam symbol

•When the heat circuit is energized the heat symbol will be energized

•The cooking mode symbol will be energized.

•The time display will invert and begin to count down.

bThe fan circuit is energized by the Control Board (A10) transmitting and receiving a signal from terminals 5,6,7 and 8 on connector X10 to terminals 3,4,5 and 6 of connector X28 on the Gas Board (A20)

cThe Gas board (A20) Transmits a signal from terminal 4 of connector X26 to the Motor Drive.

•The motor Drive Board sends a signal through the thermal switch in the motor from Terminal 5 and receives on terminal 6

•If the thermal switch is not open the Motor Drive Board (U10) sends 240 VAC 3 phase to the motor.

•The motor reverses direction every 120 seconds with a 15 second coast.

•NOTE: If the set temperature is less than 212 degrees F than fan will be pulsed on for 2 seconds every 60 seconds after the cabinet set temp (B6).

dThe steam generator heat circuit is energized

•A signal is sent from terminal 8 of connector X24 on the Gas Board (A20) to terminal 4 of connector X2 on the Steam Power Burner and Fan Control (U21) selecting the set speed of the combustion blower.

◊When this speed is attained the signal is sent from terminal 2 of connector X2 on the Steam Power Burner and Fan Control (U21) to terminal 9 of connector X24 on the Gas Board (A20)

•A request for heat is sent from terminal 3 of connector X21 on the Gas Board (A20) to terminal 10 on connector X1 on the Steam Burner Control Module (N21)

◊24 VAC is sent from terminal 2 of connector X2 on the Steam Burner Control Module (N21) to the hot surface igniter (R20).

◊The gas valve is energized allowing gas and air into the burner chamber to be ignited by the hot surface igniter.

◊The Steam Burner Control Module (N21) senses at least 1.5 micro amps DC from the flame sensor (P1) at terminal 3 of connector X2 and sends a signal from terminal 2 of connector X1 to terminal 11 of connector X25 on the Gas Board (A20)

•The heat circuit continues until both the cabinet set temperature and the bypass probe (B5) are satisfied

◊NOTE: If the set temperature is above 212 degrees F the hot air circuit will be energized (after the by pass probe is satisfied) until the compartment setting is reached. The steam circuit always takes precedence.

eWhen the condensate box is heated to 140 degrees F at the B3probe, 120 VAC is sent from terminal 5 of connector X12 to the condenser valve (Y1) until the temperature drops.

fWhen the timer counts to 0 or the core temp probe (B10) reaches the set amount the cycle ends and the steam generator reverts to the standby temperature of 190- degree F.
