DF22 Dispenser

INTRODUCTION

The DF22 Fry Dispenser is a compact, semi­automated system that replaces manual
basketing of fries and related equipment.

The DF22 Fry Dispenser automatically weighs

0.75 lb. (350 gm), 1.0 lb. (450 gm) or 1.5 lb.
(750gm) loads of frozen French fries/appetizers
and dispenses the selected weight into the Fry
Baskets each time the Dispense / Reset Button is
pressed.

The DF22 Fry Dispenser’s Hopper holds 24 lbs.
(11Kg) of frozen fries/appetizers. A rotating
Dispenser Drum inside the Hopper transfers the
frozen fries onto the Accumulator Doors where an
electronic Load Cell accurately weighs the French
fries/appetizers.

INTENDED USE

The DF22 Dispenser is intended to dispense
frozen French fries or frozen appetizers.

The DF22 Dispenser is designed to be used on
top of a stationary countertop or table, 20-24
inches (50-60 cm) tall, and capable of supporting

Loading French Fries Into Hopper

To achieve optimum fry yield and the most
consistent basket loads, it is important to use the
following technique for loading frozen French fries
into the Hopper. Depending on your French fry
supplier, you will receive your fries packaged in
boxes of six pounds (2.5Kg) each, or bags of six
pounds (2.5Kg) each. The Hopper will hold 4 bags
of fries (24 lbs. / 11Kg)).
For each bag or box of fries:

1. Remove the bag or box of fries from the case.
Be careful not to crush the fries.

2. Open the top of the bag or box completely.
NOTE: If your supplier uses bags, make sure
the bag top is fully open. If it is partially open,
fries may be retained by the bag.

3. Hold the opened end of the box or bag closed
with your hand and lay the opened end of the
bag or box into the bottom of the Hopper
against the wall opposite the Fry Diverter.

4. Release the opened end of the bag or box.

5. Empty the bag or box into the Hopper by
pulling it evenly toward the Fry Diverter.
NOTE: Do NOT shake or drop fries from the
bag or box into the Hopper.

NOTE: If the loading is done correctly, you will
leave a uniform layer of fries in the Hopper by
simply pulling the bag or box across the
Hopper toward the Diverter, and on out of the
Hopper.

6. Repeat steps 1 through 5 until the Hopper is
full. NOTE: Do NOT fill the Hopper past the
top.

7. Close the Lid on the Hopper by engaging the
hook at the back of the Hopper, and setting
the Lid down.

DF22 Dispenser

Fries/Low Bridging

If the Dispenser does not weigh the selected amount of fries within 40 seconds, the Dispenser will give a “Low Fries”
indication. The “Low Fries” indication can be caused by one of the following conditions:

• The Hopper is empty, or nearly empty. If this is the case, refill the Hopper with frozen French fries.

• An air pocket has formed around the Dispenser Drum. This happens when the fries above the Dru m lock together,

forming a “bridge”. The Drum then dispenses all the fries under the bridge, and is unable to dispense any more.
This is resolved by gently stirring the fries around by hand to collapse the bridge. Bridging of fries usually occurs
when a large number of fries is kept in the Hopper for several hours, and has been allowed to thaw.

• The "Low Fries" indication can also be caused by a mechanical failure of the Drum, Motor, or Weighing System.
When a “Low Fries” condition occurs:

1. The Drum will stop turning.

2. The weight setting lights will begin flashing slowly (about one flash per second).

3. A waiting basket will not be filled (although there may be a partial load of fries in the Accumulator Doors).
The Dispenser will retry the weighing again in 90 seconds. Therefore, the expected behavior when the Hopper is

empty is: 40 seconds of Drum turning, then for 90 seconds the Drum is halted, 40 seconds turning, 90 seconds halted,
and so on, until the Hopper is filled and the Accumulator Doors receive the proper weight of fries.
After refilling the Hopper, if the crew needs fries immediately, they may push the Dispense / Reset Button, which
accelerates the weighing cycle and causes the following actions:

1. The current weight setting light will become steady.

2. There will be a two-second pause (for Load Cell stabilization).

3. The Weighing Cycle will restart.
If the Dispense / Reset Button is not pushed, the weighing process will resume after a 90-second time-out is over, and

the current weight setting light will stop flashing when the Accumulator Doors have received the selected weight
amount.

Error Mode

There are a couple of ways that the normal cycle can be interrupted. These are primarily informational, but represent
conditions that may deteriorate into system failure. In these cases, when the Dispenser detects such a condition, it will
halt the Dispenser operation and allow the crew to correct the problem.

The sequence when an error is detected is the following:

1. All weight setting lights begin flashing quickly (about five times per second).

2. The error code appears internally on the Diagnostic display (see page

3. The Drum Motor stops turning.

4. The Accumulator Doors stop moving.
The Dispenser will remain in this mode until restarted. When the crew has fixed the problem, the Dispenser can be

restarted by pressing the Dispense / Reset Button. The lights will stop flashing and the Weighing Cycle will resume.

Sequence of Operations

Power Up

When the Dispenser is turned on the Dispenser performs an internal self test. The self test takes less than
one second. The Dispenser then waits for the load size to be selected before starting. During this phase,
the Dispenser will not attempt to move or actuate anything.

Normal Weighing Cycle

The primary function of the Dispenser is to weigh out fries for dispensing into baskets. The goal is to
provide a reasonably consistent weight within a given time frame. The Weighing Cycle is triggered when
the Accumulator Doors close after dispensing fries, when the weight setting is increased, or when the
Dispense / Reset Button is pressed.

or all of the Weighing Cycle will be skipped.

Start Drum Motor The Drum Motor is turned on at full speed until the Load Cell

indicates that the weight of fries is within a quarter of a pound
of the desired weight.

slowly deliver fries to the Accumulator Doors. This improves
the accuracy of the weighing.

15 sec. Full Weight When the Load Cell reads full weight, the Drum Motor stops.

The Dispenser waits an additional 2 seconds to be sure that it
isn’t stopping on a false reading.

17 sec. Stable Weight If the Load Cell reading remains within tolerance, the

weighing sequence ends.

40 sec. Weighing Time-out If the Dispenser has been unable to get the target weight by

this time, it stops the Drum Motor and gives a low fries
indication.

130 sec. Weighing Retry If the weighing times out, the Dispenser restarts the Weighing

Cycle after 90 seconds.

The Service Interface.

In the back of the Dispenser, on the Controller Circuit Board is the service interface. This service interface i s used to
adjust the basket load sizes and to test and adjust the operation of the Dispenser. The serv ice interface consists of
three LED displays and two push-buttons. The SELECT Button is used to select a function to be executed, or to
cancel a function in progress. The ENTER button is used to initiate (enter) a selected function.

Power Up

During a normal power up, the Controller does a segment test on the display. The display will show all eights, as
shown below, for this test. During the segment test the Controller will also run a test of the memory and program.
Upon failure of any of these tests, the Controller will stop, leaving the segment test (888) on the display. Normally the
display will flash quickly when powering up the Dispenser.

Normal Operation

During Normal Operation, the display will show a series of horizontal bars, as shown below. This display indicates that
all tests have passed, no errors have occurred, and no function is in use. If the Controller does not give this display
shortly after power up, there is a problem.

Error Condition

When an error occurs, all the Control Panel Lights will flash rapidly (5 times per second). Normally, an error
condition can be cleared by pressing the Dispense / Reset Button. If an error persists or occurs too often,
you may need to know what error is occurring. For this purpose, when an error occurs, the center digit of
the normal display is replaced with an error code number. The example below is displaying error code
number 2.

Usually, the error code will lead you to the cause of the problem.

Error

Error Name Error Definition

Number

1 ACCUMULATOR

There is a problem with the Accumulator Doors.

TIME_OUT
2 ERR_WATCHDOG The watchdog timer fired (abnormal reset)
3 ERR_NVRAM Checksum error for the non-volatile storage.

See page 25 for more details.

Selecting a Function

The Controller has several functions that may be used to adjust and test the functions of the Dispenser.
These are accessed using the following procedure:

Press the SELECT Button the number of times as the function number desired.
Each time you press the key the display will show the function code for the function that is ready.
The example below shows Function 7: (Adjust Switch Position #1 DOWN.)

NOTE: If you leave the display in this mode, it will return to Normal Operation after a few seconds. This is a

safety feature, to prevent functions from being selected by accident.

When the display shows the desired function number, press the ENTER Button to activate the
function.

What happens next depends on the function selected.
Pressing the ENTER Button will advance the function to the next step, pressing the SELECT Button

will close the function.

DF22 Dispenser

Function Reference

Function 1 - Restart

Returns immediately to the normal display. This function serves the same purpose as the Dispense / Reset
Button on the front panel. This provides a means of restarting the Dispenser without reaching around to the
front of the Dispenser.

Function 2 - Display Last Error

Displays the error number of the last error to happen. This allows the Dispenser to be restarted after an
error, and then find out what the error was while the Dispenser is in service. Exit using either the SELECT
or ENTER Button.

Function 3 - Disable Weighing

Returns immediately to the normal display. Turns the weighing process on and off. This is used mainly for
testing of the mechanical systems. It prevents the Dispenser from weighing out fries, when the fries are not
needed. This is commonly used while testing the mechanical systems, or while diagnosing or calibrating
the Load Cell. If weighing is not turned back on, it will be automatically restarted the next time the
Dispenser is turned off and on.

Function 4 - Tare

Returns immediately to the normal display. Establishes a new zero point for the Load Cell. Before
selecting this function, make sure that the Accumulator Doors are empty.

Note: This function is redundant to the front panel calibration cycle.

Function 5 - Calibrate

Displays the word “CAL” on the display. Clean off the Accumulator Doors and apply a 1 lb./16 ounce (450
gm) reference weight. Wait 10 seconds, then press the ENTER Button. The display will return to normal.
This function uses the reference weight to calculate new targets for the 0.75 lb./ 12 oz. (350 gm), 1 lb./16
oz. (450 gm) and 1.5 lb./24 oz. (700 gm) loads.

Note: This function is redundant to the front panel calibration cycle.
Note: For accurate calibration, tare the Weighing System (Function 4) before calibrating.

Function 6 - Adjust Switch Position #1 ( 0.75 lb./12 oz./350gm) UP

Displays the current target value (in ounces or grams, depending on units setting) of switch position #1. The
default value for switch position #1 is 12 oz. (350 gm). Pressing the ENTER Button causes the value to
increase by 1 oz. (25 gm.), with each activation. When the desired value is reached, press the SELECT
Button to close the function and set the value.

Function 7 - Adjust Switch Position #1 (0.75 lb./12 oz./350gm) DOWN

Displays the current target value (in ounces or grams, depending on units setting) of switch position #1. The
default value for switch position #1 is 12 oz. (350 gm). Pressing the ENTER Button causes the value to
decrease by 1 oz. (25 gm.), with each activation. When the desired value is reached, press the SELECT
Button to close the function and set the value.

Function 8 - Adjust Switch Position #2 ( 1 lb./16 oz./450 gm.) UP:

Displays the current target value (in ounces or grams, depending on units setting) of switch position #2. The
default value for switch position #2 is 16 oz. (450 gm.). Pressing the ENTER Button causes the value to
increase by 1 oz. (25 gm), with each activation. When the desired value is reached, press the SELECT
Button to close the function and set the value.

Copyright © 2005 Automated Equipment LLC All Rights Reserved

21

DF22 Dispenser

Function 9 - Adjust Switch Position #2 (1 lb./16 oz./450 gm) DOWN:

Displays the current target value (in ounces or grams, depending on units setting) of switch position #2. The
default value for switch position #2 is 16 oz. (450 gm.). Pressing the ENTER Button causes the value to
decrease by 1 oz. (25 gm.) with each activation. When the desired value is reached, press the SELECT
Button to close the function and set the value.

Function 10 - Adjust Switch Position #3 (1.5 lb./24 oz./750 gm) UP:

Displays the current target value (in ounces or grams, depending on units setting) of switch position #3. The
default value for switch position #3 is 24 oz. (750 gm). Pressing the ENTER Button causes the value to
increase by 1 oz. (25 gm), with each activation. When the desired value is reached, press the SELECT
Button to close the function and set the value.

NOTE: Adjusting the target weight above 1.5 lbs./24 oz. (750 gm) is NOT recommended.

Function 11 - Adjust Switch Position #3 (1.5 lb./24 oz./750 gm) DOWN:

Displays the current target value (in ounces or grams, depending on units setting) of switch position #3. The
default value for switch position #3 is 24 oz. (750 gm). Pressing the ENTER Button causes the value to
decrease by 1 oz. (25 gm), with each activation. When the desired value is reached, press the SELECT
Button to close the function and set the value.

Function 12 - Watchdog Test

The Controller has a timer on it that resets it in the event that an electrical surge causes the Controller
circuitry to freeze. During normal operation, the Controller program signals the timer several times per
second, to prevent it from firing. This function tests the timer by locking up the program so that the
watchdog timer fires. When this function is selected, nothing will happen for approximately 1.5 seconds,
then the Controller will reset. You will see the segment test flash by, and then display Error #2 (Watchdog
Timer Fired).

NOTE: This function causes a Watchdog Timer Error, and will be recorded as such. To prevent confusion,
you may want to clear the error log (Function 18) after using this function.

Function 13 - Load Cell Readout

Displays the current Load Cell reading. This is the raw value (it is not compensated for any offset or
calibration), and is used to test the Load Cell. This is a live display, and changes constantly with the Load
Cell input. Pressing the SELECT Button closes the function. Load cell Tare should be 75-125 (approx.).

NOTE: This function does not interfere with any operations of the Dispenser and can be used during normal
operations and as a diagnostic tool.

Function 14 - Actuate Doors

Display remains “F14”. Each time the ENTER Button is pressed, the Controller will change the state of the
output that drives the Accumulator Doors (if it is off it will turn it on, if it is on it will turn it off). This function is
used to test the Accumulator Door assembly.

Function 15 - Actuate Drum

Display remains “F15”. Each time the ENTER Button is pressed, the Controller will change the state of the
output that drives the Dispenser Drum (if it is off it will turn it on, if it is on it will turn it off). This function is
used to test the Drum Motor.

Copyright © 2005 Automated Equipment LLC All Rights Reserved

22

DF22 Dispenser

Function 16 - Actuate Lights

Display remains “F16”. Each time the ENTER Button is pressed, the Controller will change the state of the
outputs that drive the Control Panel Lights (if the panel lights are off it will turn them on, if they are on it will
turn them off). This function is used to test the Control Panel Lights (LED’s).

Function 17 - Restore Defaults

This function resets the 0.75 lb./12 oz./350gm, 1.0 lb./16 oz./450 gm, 1.5 lb./24 oz./750 gm, and tare values
to programmed default factory values. These will change when the Tare and Calibrate functions are
performed. This function is intended to be a general purpose function, which will restore the memory state
of the Dispenser to what it was when it was first powered on. This function also clears the error log and
resets the programmed modes. Function 20 will display the specific calibration values.

NOTE: Function 17 will reset the units to “US” units. If international units are preferred, Function 21 must be
performed before calibration.

Function 18 - Clear Errors

This function sets each of the counts in the error log to zero. This can be done at any time, as it has no
effect on anything else. It is recommended that this be done periodically to prevent records of occasional
errors from building up (even a perfectly running Dispenser will get occasional errors from improper
handling) and confusing a service technician at a time when the error log could be useful. In any case,
errors should be cleared after every service call to prevent the errors invoked during the call from causing
confusion in the future.

Function 19 - Error Counts

Displays the word “Err”. Each time the ENTER Button is pressed, it moves to the next error count. When
the last count is passed, the display returns to normal mode. The error counts are displayed in numerical
order. Error number 3 is not included (error number 3 indicates a memory failure, and therefore renders
any history meaningless). For example, if you saw this sequence of displays:

“Err”

“1. 12”

“2. 0”

This would indicate that since the last time the errors were cleared, error number 1 had occurred 12 times.

Function 20 - Parameters

Displays the word “Con” (constant). Each time the ENTER Button is pressed, it moves to the next
parameter. When all parameters have been displayed, the display returns to the normal mode.

The weighing parameters are (in order of appearance):

1. Switch position #1 target - the number of digitizer steps that represent 0.75 lb./12 oz. (350gm). The

default value is 38 (US) or 39 (International).

2. Switch position #2 target - the number of digitizer steps that represent 1.0 lb./16 oz. (450 gm). The

default value is 51 (US) or 50 (International).

3. Switch position #3 target - the number of digitizer steps that represent 1.5 lb./24 oz. (750 gm). The

default value is 77 (US) or 83 (International).

4. Default tare - the value that the Dispenser uses for zero when it first powers up. The default value is 40

NOTE: After the Load Cell has been calibrated, or the loads adjusted, these values may be different

5. 1.0 lb./16oz. (450 gm) Value: Calculated during calibration procedure. Reference weight value minus the

tare value.

Copyright © 2005 Automated Equipment LLC All Rights Reserved

23

DF22 Dispenser

6. Set-1 value: Manually adjusted value for small basket load. From setting via Functions 6 &7. Default

value is 12.

7. Set-2 value: Manually adjusted value for the medium basket load. From setting via Functions 8 & 9.

Default value is 16.

8. Set-3 value: Manually adjusted value for the large basket load. From setting via functions 10 & 11.

Default value is 24.

9. Calibration reference: Calibration target weight (Defaults: 16 U.S. or 18 International).

10. Close time: Expressed in 1/100’s of a second. Calculated as time of 1 revolution minus the open time of

the Accumulator Motor (Item 11). Normal value is 84.

11. Open time: Expressed in 1/100’s of a second. Calculated as 1/3 of 1 revolution of the Accumulator

Motor. Normal value is 42.

12. In flight weight adaptive value to improve weighing accuracy.

13. In flight weight adaptive value to improve weighing accuracy.

Function 21 - Select Weight Units “US” or “In”

Entering this function permits selection of ounces or grams as the weighing units. Pressing the ENTER
Button will toggle the display between ounces “US” and grams “In” (international) for the weight units.
Pressing the SELECT Button sets the displayed weight units for Dispenser operations and forces the
calibration values to the proper default values.

NOTE: Calibration must be performed after changing this setting.

Function 22 - Exercise Mode (volatile setting)

When the Dispenser is in the exercise mode, all systems will continuously cycle. The exercise mode is
designed to “break in” a replaced component. The exercise mode is volatile and will reset when the
Dispenser power is turned off.

Function 23 - Display EPROM Revision Level

After entering this function, the readout will display the revision level of the installed EPROM.

System Errors

Error List

The status of the Fry Dispenser is indicated by the operations of the Control Panel lights (LED’s).
When the Hopper is filled and operating normally, the Push-button LED’s operate normally.
When a System Error occurs, the Push-button LED’s will begin flashing rapidly (approximately 5 times per

second).
In most cases, this signals the need for a minor adjustment or that something has been assembled

improperly.
If the cause is not immediately apparent, the error code can be read from the display on the Controller.
Once the fault has been corrected, the Dispense / Reset button will reset the error and return the Dispenser

to normal operation.

Error

Error Name Error Definition

Number

1 ACCUMULATOR

TIME_OUT

There is a problem with the Accumulator Doors

hardware.
2 ERR_WATCHDOG The watchdog timer fired (abnormal reset)
3 ERR_NVRAM Checksum error for the non-volatile storage.

If the display remains blank, or remains with all segments on (888), the EPROM is bad.

Error Definitions

Error #1 - Accumulator Time Out

Accumulator Home Switch fails to turn off within 0.6 seconds of the motor being turned on, or it fails to turn
on within 0.5 seconds of the motor output starting. Error will occur if the motor or home switch is
disconnected, obstructed, broken, or the associated input or output on the controller PCB has failed.

Error #2 - Watchdog or Abnormal Reset

An event other than a normal power up has caused the processor to restart. This could be a watchdog
reset, (indicating that the processor has hung or Function 12 was entered), a processor reset (an EMI/RFI
problem), or the processor has detected corrupted memory.

Error #3 - NVRAM Checksum Error

The processor writes the permanent data (error logs, configuration, and operating parameters) along with
extra data that it uses to verify the data is valid. Data may be invalid for several reasons:

a) The first time the controller PCB has been used.
b) Software upgrade. (When new software has a different memory configuration).
c) Power down interrupted a Non Volatile RAM write cycle. The write cycle usually happens when the

reset button is pressed to reset an error.

d) The NVRAM has failed.

NOTE: Because the error history is kept in the NVRAM, this error is not recorded.
NOTE: This error can only happen during power up.
NOTE: This error is normal the first time the Dispenser is powered after the Controller board or software

chip is replaced.
