FAILSF (Failsafe)
AA. Refer to Figure 3-12. If the oven does not reach 200°F (93°C)
in 15 minutes the temperature controller will shut off the high flame
valve and begin flashing “FAILSF” and “SET PT” alternately. You
will also note that the “2” in the ALM window stays on but the “1” in
the HEAT window turns off. This condition signals a problem in
oven heating or heat sensing.
BB. To reset the temperature controller, turn off the oven blower
switch. Wait 10 seconds and turn the oven blower switch back on.
The “2” in the ALM window, the “1” in the HEAT window, the current
temperature set point, and the words “SET PT” will be displayed
again. The temperature controller will now cycle through its normal
procedures.
d. F/C - The F/C window will display either an “F” or a “C”.
AA. The “F” indicates that the temperature displayed is in degrees
Fahrenheit.
BB. The “C” indicates that the temperature displayed is in degrees Celsius.

C. Start Up Procedures -- Electric Ovens
1. Turn blower
switch to the"ON" position. This starts the main blower fan and cooling fan. The blower circulates
air through the air fingers and must stay on during the cooking or baking process. The cooling fan cools the electrical
components and blower fan motor of the oven.
2. Check to see if the cooling fans (see Figures 1-4 and 1-6) are operating when the blower switch is turned "ON". The
cooling fans cool the electrical components and burner blower motor. The cooling fan, located at the rear of the
machinery cabinet blows air into and through the cabinet. Air is exhausted out the back of the oven. A cooling fan is
also located in the bottom of the control box to draw air through the rear louvers and out the bottom.
Clean the cooling fan grills and louvers daily.
IMPORTANT NOTE: The cooling fan will operate when the blower switch is turned "ON". It must operate to keep the
machinery cabinet below 140°F. (60° C.).
WARNING: IF FAN BLADE IS NOT ROTATING, BROKEN OR IF FAN ASSEMBLY IS MISSING FROM MAIN
BLOWER MOTOR SHAFT, DO NOT OPERATE OVEN. REPLACE COOLING FAN BLADE BEFORE OPERATING
OVEN. Serious damage could be done to the burner blower motor and/or the solid state electrical components if oven
is operated while cooling fan is not running or vent grill is plugged.
3. Turn conveyor
switch to the "ON" position. This now starts the conveyor belt moving through the oven. Set
conveyor speed digital control for desired bake time
.
4. Set desired temperature on temperature controller. Refer to previous Section B for complete temperature
controller operation instructions. See section on bake times to determine desired temperature.
5. Turn the heat
switch to the "ON" position. This will complete a circuit which supplies power to the heater.
6. Close front window.
7. When oven reaches desired temperature, wait at least 30 minutes before baking.
Power Failure
In case of power failure, turn off all switches, open oven window and remove product. After power has been
reestablished follow normal start-up procedure.
