Incoming power (220 VAC) is sent through the 2A fuse (F1.1) to The 12 vdc power supply (G1) 12vdc is sent to terminals 3 and 4 of the connector X10 on the Control Board (A10) Terminal 1 of connector X12 on the Control Board (A10) Terminal 10 of connector X13 on the Control Board (A10) The return of the Supply is sent to terminal 7 of connector X13 on the Control Board (A10) With 220 VAC to the Control Board (A10) The Operation Board (A11) is energized An alarm will sound for one second All the LED’s and the display will energize one at a time. If the ground is not found 220 VAC is sent from terminal 7 on connector X12 on the Control Board (A10) to the fill solenoid (Y3) The fill solenoid opens and the generator is filled until both probes are grounded. If the top probe becomes ungrounded for more that 5 seconds the fill solenoid (Y3) will energize. If the bottom probe becomes ungrounded the combi will fill immediately and the combi will not heat When the terminal 2 on connector X15 is grounded 220 VAC is sent from terminal 4 of connector X12 on the Control Board (A10) through the normally closed auxiliary contacts of K4 to the coil of Contactor K1 until the steam generator get to 190 degrees F (probe B4). The contactor K1 closes and 220 VAC is sent to the 9.4 KW element (E1) The normally closed auxiliary contact of K1 opens preventing the Hot Air Contactor K4 from energizing 220 VAC is sent from terminal 8 of connector X11 on the Control Board (A10) through the normally closed auxiliary contacts of K44 to the coil of Contactor K2 until the steam generator get to 190 degrees F (probe B4). The contactor K2 closes and 220 VAC is sent to the 6.27 KW element (E2) The normally closed auxiliary contact of K2 opens preventing the Hot Air Contactor K4 from energizing With the combi in the steam mode with time on the timer, the door closed and the start switch is depressed 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. The fan circuit is energized NOTE: If the 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). 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. For the first 2 minutes 220 VAC is sent from terminal 4 on connector X11 through the normally closed auxiliary contacts of contactor K5 to the K50 contactor coil K50 contactor closes and the motor turns CW The normally closed auxiliary contacts on K50 open preventing the K5 contactor from energizing. For 15 seconds the motor is de-energized and allowed to coast. For the next 2 minutes 220 VAC is sent from terminal 3 on connector X11 through the normally closed auxiliary contacts of contactor K50 to the K5 contactor coil K5 contactor closes and the motor turns CCW The normally closed auxiliary contacts on K5 open preventing the K50 contactor from energizing. NOTE: If the door switch (S7) opens by the door opening, then the fan circuit is de-energized. Then the motor will be pulsed in the opposite direction to “break” the fan. This is to stop the fan quicker for the operator. The steam generator circuit is energized 220 VAC is sent from terminal 4 of connector X12 on the Control Board (A10) through the normally closed auxiliary contacts of K4 to the coil of Contactor K1 until the cabinet reaches the set temperature and the bypass probe (B5) senses 162 degrees F. The contactor K1 closes and 220 VAC is sent to the 9.4 KW element (E1) The normally closed auxiliary contact of K1 opens preventing the Hot Air Contactor K4 from energizing 220 VAC is sent from terminal 8 of connector X11 on the Control Board (A10) through the normally closed auxiliary contacts of K44 to the coil of Contactor K2 until the cabinet reaches the set temperature and the bypass probe (B5) senses 162 degrees F. The contactor K2 closes and 220 VAC is sent to the 6.27 KW element (E2) The normally closed auxiliary contact of K2 opens preventing the Hot Air Contactor K4 from energizing If the reduced power option is chosen then the K2 Contactor is no...
