Operation
Operation and Programming (All Models)
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, PLUS & MINUS. There is a 2 line x 16 character
VFD display.
TEMPERATURE SET POINTS
For Digital Advantage ovens, there is one set point. To
enter the set point mode, press the TIME and TEMP buttons
together and hold for 5 seconds. Pressing the TEMP button,
the display will show the current setting. Pressing the PLUS
or MINUS 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. Press and hold the PLUS or MINUS buttons
to allow settings to “roll” at a much faster rate. When the
desired temperature is indicated, release all buttons. After 5
seconds, the selected setpoints will be stored and remain in
memory.
TIME SET POINTS
There is one set point for the conveyor speed. Enter the
set point mode as mentioned above. If you press the TIME
button, the display will show the current speed setting.
Pressing the PLUS or MINUS buttons will raise or lower the
desired speed setting. 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 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.
Belt Jam
This occurs when the conveyor motor fails.
REVERSING SWITCH
The oven has a belt direction-reversing switch located on
the back of the control box.
Functions
THERMAL CUT-OUT SWITCH
The 3240 Electric includes a “safety thermal cut-out switch”
for your protection. This safety related device is designed
to ensure that the Impinger I unit will not overheat and
damage the unit. In the unlikely event that the Impinger
I unit would exceed the specified operating temperature
range, the “safety thermal cut-out switch” will activate, thus
blocking power to the Impinger I unit and causing it to turn
off.
,
Caution
In order to avoid a hazard due to inadvertent resetting of
the thermal cutout, this appliance must not be supplied
through an external switching device such as a timer or
connected to a circuit that is regularly switched on and
off by the utility.
For models without 1-2-3-4, continue to page 24, “To
Change Conveyor Speed.”
