WARNING:
OPERATION /
PROGRAMMING (CONT’D)
INTRODUCTION: START-UP AND SHUT DOWN
For the operator, the panel has 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, and DOWN. There is a two-line by
sixteen-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 TEMP push-button, the display will show the current setting.
Pressing the UP or DOWN push-buttons will raise or lower the temperature to the desired setting. In the
Fahrenheit (or F mode) the temperature is adjusted 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
For single belt ovens, there is one set point for the conveyor speed. Enter the setpoint mode as mentioned above.
Pressing the TIME button will show the current setting. The speed can be set as follows using the UP or DOWN
buttons:
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
For split belt ovens, there are set points for each conveyor belt speed. While in the setpoint mode, pressing the
TIME button again will toggle between both conveyor speed settings. Each belt can be set at different speed if
desired.
JUMPING BETWEEN MENUS
Pressing the TIME pushbutton 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. Upon the unexpected event that there
is a failure in the oven operation, the following messages will appear in the control:
PROBE FAIL
This occurs when there is no temperature being sent to the controller from the baking chamber.
BELT JAM
This occurs when the conveyor motor fails.
FUNCTIONS
REVERSING SWITCH
The Digital Advantage 1100 Series has a belt direction reversing switch located on the back of the oven which
allows for right to left or left to right operation.
THERMAL CUT-OUT SWITCH
The Impinger II unit includes a “safety thermal cut-out switch” for your protection. This safety related device is
designed to insure that the Impinger II unit will not overheat and damage the unit. In the unlikely event that the
Impinger II unit would exceed the specified operating temperature range, the “safety thermal cut-out switch” will
activate, thus blocking power to the Impinger II unit and causing it to turn off.
