Cleveland ogb-10.10 Manuel Complémentaire
a
The 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.
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)
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 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).
d
The 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.
◊
(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)
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)
◊
(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)
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.
compartment setting is reached. The steam circuit always takes
precedence.
e
When 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.
temperature drops.
f
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.
