AS3 Operations and Installation Manual
Description
The AS3 spreader controller provides both manual and automatic spreader operation. In automatic spreader
mode the AS3 accurately maintains a constant pounds per mile output as the vehicle’s speed varies. The
AS3 will control three electro-hydraulic proportional flow control valves; conveyor (auger), spinner and a prewet liquid valve. The AS3’s proportional valve control is fully adjustable with both minimum and maximum
drive current (or voltage) settings and the PWM frequency. The AS3 will accommodate most any electroproportional valve.
The AS3’s front panel incorporates two rotary selector switches for the operator’s Feed Rate and Lane
Width adjustments. The Feed and Lane settings are reported to the operator from a digital display located
directly above each rotary switch. Both rotary switches are detented with bi-directional with endless rotation
and an integral pushbutton. This combination switch allows the operator to change the Feed Rate and Lane
Width with fast digital precision. For Pass and Blast simply push each pushbutton. Special selections are
accomplished by push-n-turn. The front panel is backlit and organized using color features and a three
character alpha-numeric display.

Operator Controls
Power, Spinner, Conveyor, Displays
The operator has two control knobs located on the front panel. See sketch below, each knob responds to cw
and ccw rotation and each knob is also a pushbutton. The combination of push and turn creates three
different actions for each knob; turn, push-n-release, push-n-turn.
The following table is an overview of the six spreader functions as assigned to the multiple knob actions.

Push-hold in-turn the Lane Width knob cw to select the Product number. Note, the vehicle must be
stopped to change the Product. As the Lane knob is first pushed the AS3 will move thru the Pass
selection and then as you rotate the knob the AS3 will move thru the auto/man selection and as you
finally turn the knob far enough (approx. six detents) the display will show Pr # ( 1- 4 ). Once the
desired product number is selected release the knob and the AS3 will save your selection and return
to your last operator settings. Note, as you are scrolling thru the four choices the current product
selection is identified by a decimal point that follows the product number.
Feed Rate Control with Blast and Unload

to set the nine individual Feed Rates (table), see menu 21-29
to setup the overall conveyor spreading mode, see menu 03

To change the Feed Rate simply turn the Feed Rate knob ccw to decrease and cw to increase the rate
output. The two digit display just above the Feed Rate knob will display your selection. 0=Off, rates 1 - 9
corresponds to the nine programmed Feed Rates. The AS3 uses a display feature to more easily help
the operator to pick the desired rate from a list of nine choices (feed rate table).
Feed Rate Table; The installer can enter nine different Feed Rates into a table. The operator is able
to pick from this preset rate table, ( see menus 21-29 ). The intent of this feature is to allow the
operator to easily select a Feed Rate based on viewing an actual lbs./mile number. The full table of
Feed Rate choices is displayed one at a time as the operator scrolls (turns) the Feed Rate knob. All
three digits of the AS3 display immediately jump to showing the actual lbs/mile directly from the
internal Feed Rate table. The nine elements of the rate table are sequentially displayed for as long
as the operator is turning the Feed knob. Shortly after the operator stops turning the Feed knob, the
display returns to showing the selected Feed Rate number 0 – 9.
The AS3 Feed Rate table is displayed in units of lbs per mile, the range is from 100 to 1990 lbs/mile.
To determine the actual Feed Rate the operator must mentally multiply the display number by 10.
Note: The Feed Rate display uses a decimal point.
ex.
10.0 = 100 lbs/mile
[displayed number X 10 = actual lbs/mile]
99.0 = 990 lbs/mile
100. = 1000 lbs/mile
199. = 1990 lbs/mile
Refer to the section on AS3 Displays for more information.
ƒ
Push-n-release the Feed Rate knob to start Blast, the conveyor output = 100%. All throughout the Blast
activity, the display will show bL. Upon releasing the Feed Rate knob the Blast off-delay timer begins
counting down. A second push-n-release will end the Blast timer. The Blast stops automatically at the
end of the timer period. The Blast off-delay timer is adjustable, range 0 to 30 seconds. ( see menu 09 )
ƒ
To Unload the hopper, the vehicle must be stopped. Push-n-turn the Feed Rate knob ccw and release,
the conveyor output = 100% and the display will show UL. To stop the unload process, simply push-nrelease the Feed Rate knob a second time. Note; the spinner is enabled during the unload and the
operator can run the spinner at any setting 0-9, 0 = Off. If the vehicle speed goes above 5 mph the
unload will automatically reset both Feed and Lane to Off
Displays
The AS3 uses a simple three character LED display to present a wide variety information to the operator.
Through out the AS3 manual you will see notations to point out the individual displays and codes, ex. bL
means Blast and PA S is for Pass. The following chart shows the common operator displays. More detailed
displays are revealed later in the programming section of this manual and are not generally relevant for the
operator.
In addition to the three alpha-numeric characters there are two status indicators which show thru from the
backside. One is for Auto and another is for Manual spreader operation. Plus an audible beeper.

Installation with initial power up and check out
Always install the AS3 inside the vehicle cab. The 3-piece bracket is designed to offer the installer a
selection of mounting positions. Above, below or behind a panel. (see mounting drawing) Ensure the AS3 is
mounted in a position that gives the operator easy and clear access to the control knobs. Make a secure
mount to avoid vibration. Route the cable harness to the required locations and make the connections as per
the wiring diagram (see wiring drawing).
The process of setting up and calibrating the AS3 spreader control is made easier by proceeding through the
following steps in sequence. The following steps are an operational check list for verifying the overall
spreader control. Do not proceed on with the programmable calibration settings until the following operational
items check out correctly.
1.
Hydraulic components are to be fully plumbed and ready to run.
2.
Cable harness installed with all devices and terminations completed.
( mph signal wire can remain unconnected until later in the test )
3.
AS3 controller is mounted, cable connected and 12 volt power is ready to go.
( note; the AS3 is a negative grounded device )
4.
To power up the AS3 simply press the Lane Width knob in and then release when the digital display
comes on, you will also hear a short audible chirp confirming the power up is complete.
5.
Switch the AS3 to manual mode to check out the conveyor and spinner operation. First, push in
Lane Width knob and hold it in. Next, rotate the knob clockwise 2 detents, look for auto lamp to go off
and the manual lamp to come on, release knob. The AS3 will now directly output manual drive
signals to the conveyor and spinner valves. (go to step 6)
6.
From manual mode you are to verify the basic hydraulic operation. Simply rotate the Feed Rate
knob to change the speed of the conveyor or rotate the Lane Width knob to change the speed of the
spinner. Operate both knobs throughout all of the settings 0, 1, 2, 3, … 9 and verify proper hydraulic
operation. Check for proper rotation, leaks, etc. Note; the min and max speeds may not be accurate
at this point. Fine tuning individual adjustments is made later in the program setup section.
7.
If liquid is used verify liquid output, ( liquid output is active anytime the conveyor is active )
8.
MPH test. First you will need to determine the type of MPH sensor. Most trucks manufactured today
use electronic MPH signals generated from the transmission or ECU (engine control unit). The AS3
includes a program step where the installer must select the MPH signal type. (see menu 05)
The AS3 offers an input circuit for the four types of sensors;
ƒ AC zero crossing signal generator with a 300 mv ac peak-peak threshold
ƒ DC sink current sinking sensor, open collector NPN typ. V in low = 1vdc max, V in high = 6vdc min
ƒ DC source current sourcing sensor, open emitter PNP typ. V in low = 1vdc max, V in high = 6vdc min
ƒ Coupled edge sensing, series capactive coupled, 1uf
General tips: Vehicles with ECU the mph signals are typically DC sinking type. For trucks where the
installer is going to tap into the transmission tail shaft sensor, use the AC type. Some newer small
body trucks use the DC sourcing sensors. The option to use Coupled is usually done when the other
types won’t work.
With the mph signal correctly wired, power up the AS3, in auto mode, auto lamp blinks when there is
NO mph signal being generated (normal). Jack up the rear end of the vehicle, be safe and use wheel
blocks. Put the transmission in gear and let the rear wheels rotate ~ 5mph. If the auto lamp goes
from blinking to on-steady you have a good mph signal. If the auto lamp remains blinking you will
need to change the mph sensor type. (see menu 05)
9.
If the spreader valves and motor speeds operate and the AS3 can detect a MPH signal then you are
ready to proceed with the detailed setup and programming tasks.
How to access the program mode
Start with the unit powered off and simultaneously press-n-hold both the Feed Rate and Lane Width knobs
(pushbuttons). Hold both knobs in for about 3 seconds, observe the unit power up and display stops on
SH O (this is short hand for “show” or view only mode), release both knobs. Next, you must enter the pass code,
press-n-hold just the Feed Rate knob and then turn the Lane Width knob until the correct three digit pass
code appears on the display. Release the Feed Rate knob, the display now shows Pr g (this is short hand for
“program mode” ), If the pass code entered is incorrect the display will return to showing SH O, (view only mode).
The correct pass code for the AS3 is located on the last page of this manual.
To exit the program mode, from any menu # you can simply press both pushbuttons and hold them for ~3
seconds. The display will show SH O and then a moment later the display = 8.8. 8. You can now release
both pushbuttons, you’re be back in normal run mode.
How to make changes to the internal memory settings
Once you’re in program mode re-use the following two steps to make changes to any of the internal settings.
Note, some menu items are view only.
A.
Select a menu # you want to edit from the program list. First, press-n-hold the Lane Width
knob while turning the Feed Rate knob until the desired menu number is displayed, xx P.
(xx = program menu number ranging from 01-99, this list may change as new features are added).
B.
To change a setting press-n-hold the Feed Rate knob and then turn the Lane Width knob until
the desired setting is displayed. The newly changed setting is automatically and immediately
saved into the non-volatile memory (no special battery backup is required).
Program List
The AS3 uses a simple list of menu numbers to assign each adjustment, mode or feature selection. The
program list has been organized into logical groupings and presented in a sequence that aids the installer. At
the head of each section there is a brief description of the installers task. Within the body of the text are
references to other areas the installer should consider. Through out you will see a notation like; (xx), This
highlighted value denotes the factory setting for that menu item. The factory settings were selected to give
the installer a basic operational system. Changes to the factory settings are expected since every vehicle, its
hydraulic components and individual spreading policies are different.

Valve drive setup
PWM freq., current/voltage control, min and max trim
The valve drive circuits are factory calibrated and preset for current mode operation. It’s
recommended that you use current control which regulates the PWM to hold the current constant
thus compensating for changes in battery voltage and valve coil resistance due to thermal effects.
However, if you’re experience difficulties with a particular valve coil operating in current mode you
can change to voltage control mode. In either mode, the AS3 always displays the valve drive
settings as a percent number of full scale, ( range .1 – 99.9% )

(*)
To adjust a valve trim;
First select the correct menu # (16-19), next press-n-hold the Feed knob
and adjust the Lane knob for the desired shaft speed output. Repeat these
steps for each of the four valve trims.
Conveyor trim considerations; The conveyor min is the easiest setting to make, simply adjust the valve
min trim for a slow smooth creep speed as observed at the conveyor shaft. The conveyor max is a little more
difficult, the installer needs to set the valve max for the greatest shaft speed without overdriving the valve.
The best approach is to adjust the max trim from a low setting proceeding slowly to higher settings until the
max conveyor RPM is just achieved. Using a handheld RPM gauge on the conveyor shaft will create a more
accurate result. Raising the max trim beyond the peak RPM will distort the conveyor calibration. (see menu
20)
Spinner trim considerations: The spinner min is always associated with Lane Width 1 and the spinner max
is associated with the highest Lane Width selected. (see menu 31). Also important, whenever making
spinner adjustments with an empty spinner (no granular material) it will rotate without a load and tend to spin
too fast. The AS3 has a feature where the installer can have granular material dump from the conveyor while
making the individual spinner adjustments. (see menu 30)
(Special note) There is a built in current meter (amp-meter) within the AS3 that can be useful for
troubleshooting. When setting any of the valve trims, menus 16-19, before pressing the Feed PB simply
rotate the Feed Rate knob cw a few clicks. The display now shows a number corresponding to milliamps.
The displayed current is only updated every .75 sec., be patient and adjust the valve trim slowly. To return to
viewing the valve drive as a percentage turn the Feed knob ccw a few clicks before pressing the Feed PB.

The conveyors maximum trim must be correctly set for this calibration to be accurate.
Perform the test dump using manual mode at a Feed Rate = 9.
Calculation: max conveyor output, lbs/min = total pounds dumped / total time dumped
Enter the resulting number at menu 20.
Automatic spreading mode uses preset lbs/mile Feed Rates. Based on your spreading
policy, select an individual lbs/mile set point for each of the nine Feed knob positions. If less
than nine different rates are required set the all of upper knob positions to the same highest

value.
The AS3’s displayed Feed Rate must be multiplied by 10 to determine the actual Rate.
Remember the AS3 displays feed rate values use a decimal point. Which must be
considered when interpreting the actual value.
ex.
10.0 = 100 lbs/mile
[digits displayed X10 = lbs/mile]
99.0 = 990 lbs/mile
100. = 1000 lbs/mile
199. = 1990 lbs/mile
Manual spreader mode arranges the Feed Rate knob positions into fixed even increments
between 0% and 100%. Note; 0% = conveyor min trim and 100% = conveyor max trim. The
installer cannot change the manual settings for the conveyor output.

Menus 30 - 38 allow the installer to set the spinner speed for each switch position on the
Lane Width knob. You may also define the number of lanes available to the operator and
have the conveyor run during spinner adjustments for a more accurate results.
Conveyor active
This is feature allows the installer to run the conveyor while setting the spinner
speeds. This achieves a more accurate result since the granular material
effects the spinner speed. A visual verification of the spinner distance (throw)
also creates a better result. The number you enter is a percentage (0 – 99%) to
directly control the conveyor speed This feature resets to zero (turns off) each
time you enter the program mode. This feature runs the conveyor when making
the spinner min and max trim settings (see menus 18,19) or Lane Width settings
(see menus 32-38).

The Max Lane selection establishes how many Lanes will be allowed for the
operator. The AS3 is factory set with nine lanes evenly distributed between min to
max. The AS3 will automatically redistribute the individual Lane Width settings
evenly across the active number of lanes. This redistribution will only occur when
the Maximum Lane selection is changed. After the Max Lane selection the
installer can individually change any spinner speed using the menu list below.
Recall Lane settings for knob positions 1 and 9 are set using menu 18 and 19.
Enter the number of lanes you want available to the operator into menu 31. The
range is from 2 lanes to 9 lanes.
Factory = 9 lanes
Example; Enter a setting of 5 to remove lanes 6,7,8,9.
The 5 active lanes are now: 1, 2, 3, 4, 5
Lane Width
Since the AS3 starts out w/ automatically assigned spinner speeds it’s the installers option to
change these to more accurate spinner speeds. To change an individual Lane setting, first,
press-n-hold the Feed knob, observe both the spinner and conveyor (if menu 30 is active)
outputs go active. With the Feed knob held in, turn the Lane knob to change the spinner
speed. Release the Feed knob to store your new setting. The display always shows the
spinner drive as a percentage.
Note; the first (lowest) lane number is always one, Lane 1 is set using menu 18 and the
largest lane number is always set using menu 19

Start up
The AS3 allows the installer to define some start up settings. The factory have the AS3
power up in Automatic spreading mode with both Feed Rate and Lane Widths = zero
(outputs off). This is the safest arrangement since it requires the operator turn at least one
knob before spreading can occur.

Products
The AS3 allows the operator to select from four granular products. The AS3 names the
products 1, 2, 3 and 4. Product 1 is the granular material used for the primary conveyor
calibration (weight/time dump). The other three products are defined simply as a ratio of the
calibrated material weight and the weight of the alternate product.
An easy method for determining the ratio is to use a simple bathroom scale and a 5 gallon
bucket. Fill the 5 gal. bucket full and flush to the top and weigh it for Products 1-4.
Use the formula below to calculate each product ratio, enter these ratios using menus 42-44.
To effectively turn off a product, enter a ratio of 1.00
weight of Prod. (2,3,4)
Product ratio = ------------------------------weight of Prod 1
range ( 0.1 to 5.00 )
Example;
Product 1 is sand weighing 75 lbs and product 2 is a sand/salt mix weighing
62 lbs. 62 / 75 = .826667 (rounded = 0.83). Enter 0.83 into menu 42.
Product 2 is selected for dumping the sand / salt mixture.

Liquid drive mode

OFF turns liquid channel off
sel. for liquid solenoid valve
future use only, do not use
factory = OFF
note: the liquid output for the AS3 currently only supports a solenoid (bang-bang) liquid
valve. If you're not using the liquid output its very important to select the Liquid drive mode
OFF. If the liquid output is used to turn on a 24P or a solenoid valve, select the OL t option.
Do not use the Cu r option, this is reserved for a future PWM liquid drive option.

switching.
(**)
The customer is to supply an emergency shut-off disconnect switch to ensure the operator has a direct method to
interrupt vehicle power to the AS3 and thereby immediately stop the three hydraulic functions, auger, spinner, liquid.

Application Note:
Liquid pre-wet using 24P01
Wiring connections for using a 24P and the AS3’s liquid channel output. The AS3’s liquid output provides
power to the 24P. The liquid output drive mode is factory set = Off. To activate the liquid output use menu 45
to select the voltage drive mode. This allows the liquid output to go active (On) anytime the conveyor is
active. The 24P provides the proportional drive to the liquid valve. Note, this method limits the liquid drive
output current to 2.5 amps. If greater currents are required by the liquid valve use a relay.

Program Access Pass Code
The AS3 requires the installer to enter an access pass code in order to make changes to any internal settings. If the installer or
supervisor wishes to keep this code secret, remove this portion from the printed manual. The AS3 pass code is 8 5 4
AS302 Field Note
10-29-08
This field note addresses a programming error that relates to the MPH sensor selection.
A recent change was made to the two front panel rotary switches. The new switches use fewer
detents per revolution. The software was changed to accommodate these new switches.
However, unrelated to this required switch change, an error was introduced to the MPH sensor
selection menu. Part of this error created incorrect labels and part associated the wrong labels
with the sensor types.
This error only effected 8 units, s/n 677 - 684. The effected units do not need to be returned to the
factory. Use the table below to associate the desired MPH selection with the menu label.
Steps
1.
First verify the checksum (CS) of the program currently loaded into the AS3
CS 354 is the only version with this problem and CS A4A corrects the problem
2.
