Cleveland ogb-10.10 Manuel Complémentaire

◊

  In the full mode (3 drops in the display) the Y2 valve will be energized

continuously.

h

  When 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.

6

  With the combi in the Rethermalization mode with time on the timer, the door closed

and the start switch is depressed
a

  The front display will include a lighted bar under the Retherm 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.

b

  The 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)

c

  The 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 220

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).

d

  The steam generator heat circuit is energized. Steam production takes precedence

in the Combi mode
•

  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)

e

  After the bypass probe (B5) is satisfied then the hot air heat circuit is energized to

increase the cabinet temperature to the setting.
