FIELD PROGRAMMING MDP CONTROLS
While in Programming Modes, set decimal place/
mode variable to the proper position (0 thru 4 =
Rate 5 = Time). This allows settings to be made in
the proper units. Only set the variables that you
wish to change. You can change any variable
WITHOUT having to reset the others.
SETTING UP CUSTOM VALUES
To Enter Programming Mode (Motor Will Stop)
1. Make sure DIP switches 1, 2, 3, 4, 5, 6 and 8
are OFF. Flip DIP switch 7 ON.
2. Display reads PROG (in rate mode the current
decimal point is also displayed.
3. Use the following instructions to view and/or
edit any variable.
Displayed Decimal Place, Rate or Time Mode
Select
1. Flip DIP switch 4 (Rate-Time Mode/Program
Decimal Place) to ON.
2. Present decimal point (if any) will be lit, as well
as the current value of the decimal place variĆ
able.
3. Use Up and Down buttons to change. Use a
value of 5 for Time Mode.
4. When finished, flip DIP switch 4 to OFF.
5. The display reads PROG.
The Constant
1. Calculate the constant for your application. For
ovens with a 70 inch tunnel, 130 Volt DC or 90
VDC motor and #2 pickĆup, the constant is
5:20. For ovens with a 55 inch tunnel, 130 Volt
DC or 90 VDC motor and #2 pickĆup, the conĆ
stant is 4:08.
2. Flip DIP switch 1 (Program Constant) ON.
3. Present value for constant will appear in the
display.
4. Use Up and Down buttons to change.
5. When finished, flip DIP switch 1 OFF.
6. The display reads PROG.
NOTE: If you change the constant, the display setĆ
ting will be set to the slowest speed when
you exit the Programming Mode.
Program Minimum Setting
1. Flip DIP switch 2 (Program Minimum Setting)
ON.
2. Present value for Lower Limit will appear in the
display.
3. Use Up and Down buttons to change.
4. When finished flip DIP switch 2 OFF.
5. The display reads PROG.
Program Maximum Setting
1. Flip DIP switch 3 (Program Maximum Setting)
ON.
2. Present value for Upper Limit will appear in the
display.
3. Use Up and Down buttons to change.
4. When finished flip DIP switch 3 OFF.
5. The display reads PROG.
To Exit Programming Mode
1. Make sure DIP switch 5 (Master/Follower
Mode select) is in the desired position (ON =
Follower; OFF= Master).
NOTE: In most cases DIP switch 5 should be
set to the master position (OFF).
2. Make sure DIP switches 1, 2, 3, 4, 6 and 8 are
OFF.
3. If satisfied with programming values, set DIP
switch 7 to OFF.
4. The control begins to operate, using the values
and modes you have programmed.
Check the Belt Speed Calibration
To check the belt speed calibration place a pan on
the belt and start the conveyor.
1. Begin timing the belt's speed when the trailing
edge of the pan enters the oven.
2. End the timing cycle when the trailing edge of
the pan exits the oven.
3. If the displayed time differs from the actual
more than 5 seconds, reprogram the K"
constant. If the measured time is lower than 5
seconds, raise the K" constant in increments
of 05. If the measured time is higher than 5 secĆ
onds, lower the K" constant in increments of
05.
