OPERATION
to maintain a constant temperature.
The temperature controller contains a high-limit (safety)
switch that shuts down the oven when the oven reaches
343°C (650° F) and a low-limit switch which allows the
oven to cool down to 82° C (180° F) before shutting off the
blowers.
E. Conveyor Switch
The on/off ("I"/"0") switch for the conveyor drive motor is
on the control panel of the controlling oven section. Also
on this control panel is the conveyor speed control and
indicator (Figures 3-3A and 3-3B).

MEASURING CONVEYOR SPEED.
To measure the conveyor speed, place an item at the
product entrance end of the oven bake chamber, as
shown in Figure 3-4. Time how long it takes for the
leading edge of the item to go from the entrance end of
the bake chamber to its exit end (Figure 3-5). This is your
conveyor speed or bake time.
