I. LOCATION AND DESCRIPTION OF CONTROLS
Fig. 3-1 - Control Panel
A. BLOWER Switch: Turns the blowers and cooling
fans on and off. The HEAT Switch has no effect
unless the BLOWER Switch is in the “ON” position.
B. HEAT Switch: Allows the gas burner to light. Acti-
vation of the gas burner is determined by the settings
on the Digital Temperature Controller.
C. CONVEYOR Switch: Turns the conveyor drive
motor on and off. This switch is only present on oven
sections that have a conveyor drive motor.
D. DIGITAL TEMPERATURE CONTROLLER: A solid-
state, on-off type controller that continuously moni-
tors the oven temperature. Settings on the Digital
Temperture Controller control the activation of the
gas burner.
E. CONVEYOR SPEED DISPLAY (Tri Tandem and
Quad Tandem ovens only): Displays a DC voltage
value that corresponds to the speed of the conveyor
drive motor. Higher voltages produce a faster con-
veyor speed, shortening the bake time. The display
is only present on oven sections that have a conveyor
drive motor.
F. CONVEYOR SPEED ADJUSTMENT KNOB (Tri
Tandem and Quad Tandem ovens only): Adjusts
the speed of the conveyor drive motor. The knob is
only present on oven sections that have a conveyor
drive motor.
G. CONVEYOR SPEED CONTROLLER (Tandem and
Double Tandem ovens only): Adjusts and displays
the bake time. This control is only present on oven
sections that have a conveyor drive motor.
