FINGER HOUSING BAFFLE PLATE ADJUSTEMENTS
The finger housing has a baffle mounted inside to balance the air flow to the rear and front of the oven. If the
product is cooking more or less in the rear of the oven than in the front, it is possible the finger housing baffle needs
to be adjusted. If it is deemed necessary to adjust the air balancing baffle, be sure to adjust all eight (8) finger
housing to exactly the same opening. Determine if more air (heat) is required at front or rear of oven then open or
close off that air by bending the baffle in the proper direction. See drawing above.
PROGRAMMING THE DIGITAL ADVANTAGE 1450 SERIES TOUCH PAD
INTRODUCTION – START-UP AND SUT DOWN
For the operator, the panel has a power up, run, and program menu modes. To start the oven, turn the power
switch on. To shut down the oven, turn the power switch off.
FRONT PANEL LAYOUT
The front panel contains four (4) momentary push-buttons: TEMP, TIME, UP &
DOWN. There is a 2 line x 16 character VFD display.
TEMPERATURE SETPOINTS
For Digital Advantage ovens, there is one setpoint. To enter the setpoint
mode, press the TIME & TEMP buttons together and hold for 5 seconds.
Pressing the UP or DOWN push-buttons will raise or lower the temperature to
the desired setting. In the Fahrenheit, F mode, the temperature is adjusted in
5 degree increments. When in Centigrade, C mode, the temperature
adjustment will be in 1 degree increments. Pressing and holding the UP or
DOWN keys will allow the settings to “roll” at a much faster rate. When the
desired temperature is indicated, release all keys. After 5 seconds, the selected setpoints will be stored and remain
in memory.
TIME SETPOINTS
There is one setpoint for the conveyor speed. Enter the setpoint mode as mentioned above. The speed can be set
as follows:
1:00 to 9:55 in 5 second increments
10:00 to 12:45 in 15 second increments
13:00 to 19:30 in 30 second increments
20:00 to 30:00 in 1 minute increments
JUMPING BETWEEN MENUS
Pressing the TIME push-button while in the TEMP setting mode (and vice versa) will cause the menu selection to
jump over to that mode.
DIAGNOSTIC MESSAGES
The Digital Advantage ovens have diagnostic messages within the control. In the unexpected event that there is a
failure in the oven operation, the following messages will appear in the control.
OPEN PROBE
This occurs when there is no temperature being sent to the controller from the baking chamber.
SHORTED PROBE
This occurs when a constant temperature signal (as opposed to the normal cyclical cavity temperature) is being
sent to the controller from the baking chamber.
CAUTION: This message can also occur when there is no gas supply to the oven. If the oven does not
detect a temperature fluctuation in 5 minutes, the error message will appear. Be sure to check the gas
valve and gas hose for proper connections.
BELT JAM
This occurs when the conveyor motor fails.
