HOPPER DISPENSE RATE OF PRODUCT
The hopper dispense rates are preset at the factory. With 22 tooth gear and auger wire, the preset dispense
rate is approximately 3 to 5 grams per second. With 30 tooth gear and auger wire, the preset dispense rate is
approximately 5 to 7 grams per second. The hopper dispense rates can be individually programmed to a range
of dispense rates from approximately 1.5 to 12 grams per second by following the procedures described in
Programming Modes.
PROGRAMMING MODES
1. Enter / Exit:
a. To enter the program mode, press any two dispense size switches, on the position to be programmed, at the
same time. The L.E.D. will flash indicating the program mode.
b. To exit the program mode, press a switch on any position other than the one being programmed.
Note: The stop switch will not cause exit of program mode since it is used for some programming operations.
If in the program mode for more than 25 seconds and no switches have been pressed, the program mode is
automatically exited.
2. Dispense Run Time:
a. Enter the program mode on the position you want to program (see step 1.a.)
b. Place the “Rinse/Run” switch in the “Run” position and press and hold the cup size to be programmed.
c. When the desired amount is reached, release the switch, the time is recorded in memory.
To set the time to non-timed dispense, just momentarily press the position switch. This actually sets in a very
short timed dispense.
d. Repeat for remaining cup sizes if desired.
e. Exit the programming mode (see step 1.b.)
3. Increasing / Decreasing the Hopper Dispense Rate:
a. Enter the program mode on the position you want to program (see step 1.a.)
b. Place the Rinse/Run switch in the “Rinse” position.
c. Press and hold down on the stop switch and press the small switch to decrease the dispense rate or press
the large switch to increase the dispense rate. Each time the button is pressed, the dispense rate will increase/
decrease by approximately 2

%. Each time the small or large switch is pressed, the L.E.D. on that position
will flash on and off to indicate the switch was recognized. When the maximum or minimum level is reached
all 3 position L.E.D.’s will flash rapidly.
d. To return the dispense rate to the factory preset, press and hold down stop switch and press the medium
switch. When the medium switch is pressed, the L.E.D. on that position will flash on and off to indicate the
switch was recognized.
e. Return the Rinse/Run switch to the “Run” position.
f. Exit the programming mode (see step 1.b.)
4. Making Common Timed Dispenses: Once a position has been programmed to the proper dispense times,
you can make all 3 positions the same, as follows:
a. Place the Rinse/Run switch in the “Run” position.
b. Enter the program mode on the position you want all others to be like (see step 1.a.)
c. Press and hold the Stop switch for 10 seconds.
d. After the 10 second period, all 3 position L.E.D.’s will come on solid indicating the task is complete. The
program mode is exited when the Stop switch is released.
