52. S9 ć One Shot Steam Button. Pressing the butĆ
ton in any mode applies power to terminal 2 of
T3 One Shot Steam Solid State Timer and initiĆ
ates the steam circuit for the set time.
53. S10 ć Fan Speed Switch
D High speed, terminals 24 to 26 are closed
applying power to convection motor.
D Low Speed, terminals 24 to 25 are closed
applying power to Solid State Motor Speed
Control.
54. S11 ć Meat Probe Switch. terminals 11 to 12
close supplying power to XFMR 208V to 24V
step down transformer for the meat probe.
55. S12 ć Flush / Drain Switch
D In order to work, the oven must be in the
OFF" position and the steam generator
must be below 160_F or 71_C.
D Flush - terminals 24 to 25 close supplying
power to R203 Flush / Drain Solid State
timer.
D Drain - terminals 24 to 26 close supplying
power to the pump.
56. S15 ć Deliming switch. SPST switch used for
deliming.OFF postion is for deliming. ON for
normal operation.
57. Speed Control - Solid state motor speed conĆ
troller, drops the motor rpm to approximately 900
rpm.
58. (GAS OVENS) - Steam IGN1 ć Steam Ignition
Control Modual. Sequence of operation: input
24Vac to THS2 & GND. SPARK outputs to pilot
assembly & sparks. PV1 outputs to pilot valve
& opens valve. SPARK output continues until
flame sense is proved (.15 microamps is lockĆ
out / minimum you should see is .2 ). Lock out
of modual is after 50 seconds if flame sense
has not been proved. Once SENSE4 has
proved, MV3 outputs. MV3 supplies power to
main valve on the combination valve and burnĆ
ers light.
59. (GAS OVENS) - Transformer (designated as
120V /240V 1 KVA THERMALLY PROTECTED
to 160_C) ć step up transformer the control cirĆ
cuit for gas ovens with 120Vac input.
60. (ELECTRIC OVENS) - Transformer (desigĆ
nated as 480V / 240V 150VA") ć step down
transformer for 480V electric ovens only (transĆ
former is located under oven cavity).
61. T1 - Buzzer
62. T2 - Steam Duty Cycle Timer
D Power in on terminals 2 & 3. Output on termiĆ
nal 1
D Used to provided power to the steam circuit
in the Combi mode. Power supplied to termiĆ
nal 2, terminal 1 on for 45 seconds and off for
80 seconds.
63. T3 ć One Shot Steam Solid StateTimer
D Power in on terminals 1 & 3. Terminal 6 is
a trigger which initialize timer output on terĆ
minal 2. Resistance setting on terminals 4
to 5 determine stay on time.
D When steam injection button is pressed,
power to terminal 6 initiates power out of
terminal 2 for set time. Steam circuit enerĆ
gized for set time.
64. T4 ć Flush Solid State Timing relay. Power in is
on terminals 2 & 3. Output is to terminal 1 for
90 seconds. This energizes R203 which allows
the pump and fill solenoid to come on.
65. (GAS OVENS) - T5 ć Hot Air Duty Cycle Solid
State Timer. Power in is on terminals 2 & 3. OutĆ
put is to terminal 1 for 45 seconds on and 60
seconds off. When terminal 1 is on, power is
supplied to the Hot air circuit to boost the
Steam mode.
66. (GAS OVENS) - XFMR1 ć Step Down transĆ
former 208Vac / 240Vac to 24Vac. Supplies
24Vac to the steam ignition modual.
67. (GAS OVENS) - XFMR2 ć Step Down transĆ
former 208Vac / 240Vac to 24Vac. Supplies
24Vac to the hot air ignition modual.
68. XSFMR ć Step Down transformer 230Vac to
24Vac. Supplies 24Vac to optional meat probe
controller.
