Cleveland Range ELECTRIC 20.20 OES-20.20 - Manual (Page 64)

◊ The Contactors K42 and K62 close and 220 VAC is sent to the inner
elements (E42 and E62)
◊ If the reduced power option is chosen then Contactors K42 and K62 are
not energized.
d The steam circuit is energized
• 220 VAC is sent from terminal 4 of connector X12 on the Control Board
(A10) to the coil of the Y3 solenoid allowing water to be thrown against the
element until the bypass probe (B5) senses 183 degrees F.
e When the condensate box is heated to 140 degrees F at the B3 probe, 220 VAC is
sent from terminal 5 of connector X12 to the condenser valve (Y1) until the
temperature drops.
f When the timer counts to 0 or the core temp probe (B10) reaches the set amount
the cycle ends.
g If the “Crisp and Tasty” mode is selected
• 220 VAC is sent from terminal 6 of connector X12 on the Control Board
(A10) to the Dehumidification Valve (Y2) to pull the humidity out of the
cabinet down the drain.
◊ In the light and medium modes (one and two drops in the display) the Y2
valve will be energized until the bypass probe (B5) is satisfied.
◊ 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.
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 Rethermalization 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
• If the combi fan is in the normal setting 220 VAC is sent from terminal 5 on
connector X11 through the normally closed auxiliary contacts of contactor
K57 to the coils of contactor K56 and contactors K55.1 for the upper motor
and K55.2 for the lower motor
◊ The K56 contactor closes sending 220 VAC through the Q56.1 overload to
the motors.
◊ The K55.1 contactor closes completing the high speed circuit to the upper
motor and the upper motor turns at a high speed.
◊ The K55.2 contactor closes completing the high speed circuit to the lower
motor and the lower motor turns at a high speed
◊ The normally closed auxiliary contacts of K55.1, K55.2 and K56 open
preventing the K57 contactor from energizing.
• If the combi fan is in the reduced setting 220 VAC is sent from terminal 6 on
connector X11 through the normally closed auxiliary contacts of contactors
K55.1, K55.2 and K56 to the coil of contactor K57
