◊ Voltage is sent from terminals 7 and 8 on connector X14 on the Control
Board to terminals S and F respectively on the AC drive board for 2
minutes.
(a) The AC drive board ramps up the oven fan motor (M1) Counter-clock
wise for 2 minutes.
◊ If Voltage is sent to terminal 10 on Connector X14 on the control board to
terminal M on the AC drive board the fan will turn in reduced speed.
• The hot air heat circuit is energized
◊ 220 VAC is sent from terminal 3 of connector X12 on the Control Board
(A10) to the coil
of Contactor K4 until the cabinet reaches the set
temperature (97 C) as sensed at probe B6.
(a) The contactor K4 closes and 220 VAC is sent to the element (E4)
• 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 Y4 solenoid allowing water to be thrown against
the element for 25 seconds every 40 seconds.
f 220 VAC is sent from terminals 3 and 4 on connecter X13 on the Control Board
to the Rinse solenoid (Y21) and Rinse Pump (Y20) for 12 seconds.
• The Rinse cycle is repeated 4 times with the rinse solenoid energized from
terminal 3 on connecter X13 on the control board for 20 seconds on and off
for 40 seconds.
g For 5 minutes
• The fan circuit is energized
◊ Voltage is sent from terminals 7 and 9 on connector X14 on the Control
Board to the terminals S and R respectively on the AC drive board for 2
minutes.
(a) The AC drive board ramps up the oven fan motor (M1) Clock wise for
2 minutes.
◊ Voltage is removed from the AC Drive for 15 Seconds
◊ Voltage is sent from terminals 7 and 8 on connector X14 on the Control
Board to termina
ls S and F respectively on the AC drive board for 2
minutes.
