OPERATION

E. Conveyor

The on-off switch for the conveyor motor is on the control
panel. Also on the control panel is the digital conveyor
speed control. The digital control can be adjusted from 3
min. to 30 min. bake time (conveyor speed). Refer to
Figure 3-3.

Conveyor speed is measured by the amount of time it
takes for an item to go through the bake chamber of the
oven.

MEASURING CONVEYOR SPEED.

See Figures 3-4 and 3-5.

To check conveyor speed, place a product item at the
entrance end of baking chamber as shown. Time how long
it takes for the leading edge of the item to go from the
entrance end of the baking chamber to the exit end. This
should be the conveyor speed shown on the conveyor
speed digital control.

NOTE: In Figures 3-4 and 3-5, the oven shown is with the
conveyor running right to left.
