E. Conveyor

The on-off switch for the conveyor motor is on the con-

trol panel. Also on the control panel is the digital con-

veyor speed control. The digital control can be adjusted

from 1-10 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 con-

veyor speed digital control.

NOTE: In Figures 3-4 and 3-5, the oven shown is with

the conveyor running right to left.
