◊The normally closed auxiliary contact of K4 opens preventing the Steam Contactor K1 from energizing
•220 VAC is sent from terminal 7 of connector X11 on the Control Board (A10) to the coil of Contactor K44 until the cabinet reaches the set temperature.
◊The contactor K44 closes and the third leg of 220 VAC is sent to the 18 KW element (E4)
◊If the reduced power option is chosen then the K44 Contactor is not energized.
dWhen the condensate box is heated to 140 degrees F at the B3probe, 220 VAC is sent from terminal 5 of connector X12 to the condenser valve (Y1) until the temperature drops.
eIf 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.
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.
6With the combi in the Combi 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 combi 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
•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 contactors K55 and K56
◊The K55 and K56 contactors close sending 220 VAC through the Q56 overload to the motor and the motor turns at a high speed.
◊The normally closed auxiliary contacts of both K55 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 and K56 to the coil of contactor K57
◊The K57 contactor closes Sending 220 VAC through the Q57 thermal overload to the motor and the motor turns at a reduced speed.
◊The normally closed auxiliary contacts of K57 open preventing the K55 and K56 contactors from energizing.
