2) Oven heat LED on the control goes out.
3) Oven ready LED on the control comes
ON.
4) Electronic beeper sounds momentarily.
C. The oven will continue to cycle on the
computer control until the doors are opened
or power switch (S1) is turned to the OFF or
COOL DOWN position.
Temperature and Time Cycle (Normal Cooking)
The computer's internal cook timer operates
independently of the heating cycle. Additional time
can be set or the timer can be stopped and restarted
throughout the cooking cycle.
Refer to the Installation & Operation Manual for
specific operation instructions of the oven computer
control.
Function Switch SG4C/SG6C - Selects the cooking
mode of the oven between Cook or Roast and Hold.
Is used in conjunction with the Roast and Hold timer
during Roast and Hold cooking. The selected mode
also determines the fixed blower speed: HI for Cook
and LO for Roast and Hold.
If Roast and Hold is selected, when the Roast (then
hold) time expires, the oven heating stops and the
oven enters the hold mode. Once the even cavity
temperature drops to 150°F, the heat comes back on
and the oven cycles at this temperature to hold the
cooked product.
Roast and Hold Cycle
For a detailed explanation of the Roast and Hold
mode, refer to the instructions manual.
In the Roast and Hold mode, the operation of the
computer control is identical to the normal cook
cycle, with these exceptions:
1. Oven Roast and Hold light on the control
comes ON.
2. Convection fan speed changes from HI to
LO.
A. The computer control 5 VDC output from
pins C2-2 (-) and C2-8 (=) is deactivated
and SSR1 relay is de-energized.
1) Power (120 VAC) is removed from
convection fan motor high speed
terminal.
B. The computer control 5 VDC output from
pins C2-1 (-) and C2-8 (+) is activated and
SSR2 relay is energized.
1) Power (120 VAC) is applied to the
convection fan motor low speed
terminal.
3. At the end of the cook time, the electronic
beeper sounds momentarily to indicate the
end of the first stage cooking (oven operates
normally at the temperature and time selected
until time expires).
4. The display flashes HOLD as the oven enters
the hold mode. This is also considered second
stage cooking (oven heating stops but product
continues to cook on residual heat).
A. Convection fan motor is de-energized.
B. Oven fan cycles with the output of the
heating system. Anytime the system
calls for heat, the fan must be running.
After the oven has reached the 150°F set
temperature, the heat and fan are de-
energized.
5. After the oven temperature drops below 150°F,
the heat comes back on and cycles as needed
to maintain the hold temperature of 150°F.
A. Convection fan motor energized.
6. The oven continues to cycle in this manner
until one of he following occurs:
A. The cook and hold mode is turned OFF.
B. Power switch (S1) is turned to the OFF or
COOL DOWN position.
