CALIBRATING GROUND SPEED (MPH)
It is absolutely necessary as part of the calibration process to make sure the ACS MPH
[Km/H metric mode] display matches the Truck MPH display.
MPH [Km/H metric mode] display


Drive the vehicle. The MPH [Km/H metric mode] display should match and track with
the vehicle speedometer. If it does not, then follow the instructions below.
Login to Main menu, Vehicle settings, Speed adjust.
1. Vehicle Speed input type
Use display arrow keys and F3 “Select” key to navigate to the “Vehicle Settings” then
“Speed Input Type”




VRM: This setting used for Low voltage AC signals. This type of input can be
susceptible to noise and the wiring should be shielded with a drain path to chassis
ground.
MechSRC /WA: This is the most typical setting. This setting to be used in most
applications where the MPH signal source is the vehicles computer. Always check with
the vehicle manufacturer before attaching to any vehicle wiring.
Mech Sink: When configured for this setting a pull-up resistor to +5 volts is added to the
input. Typically this setting is used for after-market hall-sensors that are NPN opencollector output.
It is necessary to reboot the ACS system each time you change the speed type to have
the setting take effect, and then continue to Vehicle Speed Adjust step below.
2. Vehicle Speed Adjust
Use display arrow keys and F3 “Select” key to navigate to “Speed Adjust” screen.
7
ACS CALIBRATION MANUAL Rev. E SG07230014




Select into Speedometer Reading and change the “Speedometer reading” value to the
vehicle speed you intend to drive at.
Drive the vehicle cautiously up to speed. Always keep your eyes on the road and perform
speed cal in an area away from other traffic or obstacles. It is recommended and much
safer if you have someone else drive the vehicle while ANY cal adjustments are made.
While the vehicle is in motion and the dash speedometer reads exactly the value you set
in “Speedometer Reading” press F2 screen key to SAVE.
Now the “Spreader match Value” should match and track with your vehicles
Speedometer.
Use display ▲▼ arrows to
adjust value up or down.
“Match Value” should match and track
with truck speedometer.
Press Accept when your value
is set to same value displayed
on truck Speedometer.

Note: If there is no signal, you will receive a “Ground Speed too low” message at the
bottom of the screen when trying to press F3 “Accept”.

CONFIGURING MATERIALS
It is important to properly setup all of your materials that will be used on the vehicle.
1. Material Menus
 Use display arrow keys and F3 “Select” key to navigate through to the “Spreader
Settings” menu to “Materials menu,” eventually ending up in Material #1 setup as
shown below.

2. How to set up materials
 On the following page is an example table filled in for a basic material setup. The
column and rows are formatted to follow the flow of menu items within the ACS
system material menus. The table shows some example settings that are
commonly chosen. Follow the instructions below.

You must calibrate the vehicle with one (1) material. All other materials are based
on a ratio of the calibrated material vs. the new material.
o Set up MATERIAL #1 as the material you will dispense during Measured
Dump. Follow the example chart on the next page as a guide. I recommend
that the first material in the list (Material 1) be the calibrated material or
Measured Dump Material.
o Below find the example table. I have included additional Blank tables to be
filled out as each material is set up. The tables you fill out will be used in the
future as a guide for additional setups or to check settings months later when
a problem may arise.
 ASSIGN A MATERIAL NAME. This will be the name that appears on the
operator’s screen. Choose 1-10 alpha-numeric characters.
Continued on next page……

Material Setup continued
 SET A WEIGHT RATIO. The material used for measured dump should be set
to 1:00 ratio typically.
o If setting ratios for additional materials, follow the example below.
Always divide the new material by the calibrated material to find the new
ratio. Use equal proportions with comparable or preferably no moisture
content, to achieve accurate ratios:

the material data in the charts provided. If in metric LBS/LM becomes Kg/LnKm.
(Blast Settings continued…..)
 Blast type:
o TIMED
 Blast timer (sets blast duration in seconds 0-99)
Note: -Setting a -0- forces a toggle operation switching
between ON and OFF each time the BLAST switch is
pressed.
o MOMENTARY (Blast is active while the ‘Blast’ switch is held down.)
 Ground Speed Rqd.>(Required)
o YES (Blast functions ONLY while the vehicle is in motion.)
o NO (Blast will function at ANY TIME.) If “Max Rate” or “Other” is
selected below under Blast Setting, please note the following functionality
without a Ground Speed signal:
 Blast defaults to Max trim if “Ground Speed Rqd.” Is set to
“No” and the vehicle is NOT moving. The control will go to
“Max Rate” or “Other” once the vehicle is moving again.
 Blast functionality with NO ground speed (the vehicle is not
moving) will record NO material output in the Storm totals or
Annual Totals.
 Blast Setting
o OTHER (See “Other Blast Setting below.”)
o MAX RATE=Blast will go to the “Maximum Rate” setting for this
material. (You set this at the beginning of Materials section.)
o MAX TRIM (Blast will go to the “Max Trim” setting for the Feeder
Valve.)
 OTHER BLAST SETTING (Use alternative Rate 0-9999 Lb/Lane Mile or
[Kilograms/Lane Mile])
 Note: You are limited by the physical maximum output of
material the feeder will deliver.

PREPARE FOR CALIBRATION

WARNING: Keep all personnel clear of the vehicle and mechanism before
continuing. The feeder is live while in measured dump!
 Make sure gate is fixed at proper opening for your spreader. Make sure typical
baffles/plates/shields are installed.
 For tailgate spreader, adjust plates for typical auger opening.
1. Bring the Hydraulic system up to temperature:
 It is better to calibrate the system at typical operating temperatures especially
open-loop calibration (no feedback sensor installed).
 The Minimum trim level may be affected if set when the hydraulic oil and motor
are not at normal operating temperature. This is especially important if running
open-loop!
MAKE/CHECK TRIM ROUGH ADJUSTMENTS


1.
Before loading the vehicle: It’s good to set rough trims - that way you’re not
emptying the vehicle of all material after you go through the hassle to load it.
Follow the menu sequence below to make ROUGH trim adjustments. Use arrow
and F3 Keys to navigate to the trim screens shown below.
o Min trim, Adjust min trim for a min pulse count between 300-600
pulse/minute and SAVE.
o Max Trim, Adjust max trim and SAVE the new max value. Highest pulse
count possible should be achieved without overshooting it.

Be sure to press “Accept”
after new level is set.
13
ACS CALIBRATION MANUAL Rev. E SG07230014
MAKE/SET TRIM FINE ADJUSTMENTS
1. Load the Vehicle with material: Load to typical capacity.
2. How to minimize mess: Back-up the vehicle close to the MATERIAL pile as possible.
 If tailgate spreader, load the auger by raising the bed until auger is loaded.
3. Fine adjustment to min and max trims: Feeder
 Follow the menu sequence below to SET FINE trim adjustments. Use arrow and
F3 Keys to navigate to the trim screens shown below.
 Min trim: With the weight of the material on the feeder, adjust min trim for a min
pulse count (sensor feedback) between 300-600 pulses/minute and SAVE.
 If running open loop (no sensor), adjust min trim to point where feeder is
running as slow as possible but without stalling.
Max trim: With the weight of the material on the feeder, adjust max trim and SAVE
the new max value. Adjust the Max Trim value until pulses stop increasing, then
lower the trim percent until pulses begin to drop-off. Now adjust Max Trim up just
until you reach the max pulse count value again. This setting is important for reliable
accurate Closed-Loop and Open-loop.
 If running open loop, it is best to use a hand held mechanical tachometer
somewhere on the feeder mechanism. Have someone use a tachometer
and call out the RPM until an increase in the MAX TRIM value no
longer increases Feeder RPM.

ACS CALIBRATION MANUAL Rev. E SG07230014
4. Important information about setting/saving trim settings

Note: If setting closed loop trims and the ACS system is not reading pulses from the feeder
sensor, the ACS system will not allow TRIM settings to be saved. See below screen. The
following points define this feature:
 Helps prevent accidental over-write of original calibrate settings saved while the sensor
was working, including OPEN LOOP settings. This can happen when a technician is
using Trim screens for diagnosis of system problems.
 Helps prevent Trim settings from being corrupted or set incorrectly by requiring a
working sensor (active sensor feedback) for CLOSED LOOP trim setting.
 Helps ensure the ACS system will operate reliably in OPEN LOOP (no sensor) mode
without any changes, while also preventing changes to the system configuration.
Mechanics do not have to change the controller to OPEN LOOP mode; the ACS
system simply defaults to open loop each time after the sensor “fault time-out” occurs.
This improves the reliability of accurate OPEN LOOP operation, allowing the vehicle
to return to use until the sensor can be fixed.
Lack of any sensor feedback
prevents trims from being saved.
Message; “No Sensor Pulses” is
displayed. Trim setting will not
change.
AUTO TRIM
An alternative to setting FINE TRIM ADJUSTMENTS above would be to use Auto Trim.




Complete the “Prepare for Calibration” section of this manual.
Auto-trim is only available for Closed Loop functions (feedback sensors installed).
Feedback sensors must be functioning or Auto trim will not complete.
!!KEEP ALL personnel clear of the vehicle!!
-Use Up/arrow to start Auto-trim.
-Use ESC. to exit any time
without saving changes.
-Left arrow can be used to Stop
Auto-trim at any time.
-Auto trim runs automatically
from when it’s started.
-Min trim increments up until
feedback appears in the window.
-Once min trim is reached, Auto
trim switch to max trim.
-Max trim pulses are found as the
output is feathered up and back
again to the exact Max trim value
and Max pulse value.
15
ACS CALIBRATION MANUAL Rev. E SG07230014
FAULT TIME-OUT



While in the Trim screens, set a fault time-out for the ACS control to switch into
Open-Loop mode.
Should be adjusted for a value between 1 and 30 seconds.
Time-out operation important for default Open-Loop operation to maintain a
regulated output in event of sensor failure.
-Adjust Sensor Fault time-out
value for 1 -30 seconds
CLOSED LOOP MEASURED DUMP (FEEDER SENSOR INSTALLED)
Note: Proceed to OPEN LOOP MEASURED DUMP if you have NO feeder sensor installed.
1. Check-list for (closed-loop) Measured Dump
Complete before continuing.
 Using Variable height gate? If performing a measured dump with a variable height gate,
THE FEEDER MUST BE RUN AT A FIXED SPEED. Set the gate at its typical
opening (calibrate height); then perform the measured dump at a fixed output
percent (i.e., 35% as shown on the illustration below); then continue on to section:
“CALIBRATING VARIABLE GATE” after completing Measured Dump.
o Note: The smallest gate increment is (.5). e.g. 4.5 inches or 11.5 centimeters
o Record your fixed output (when prompted below) after completing the
measured dump to use later in the Gate calibration.
 Using a Fixed Gate? Make sure gate is fixed at proper opening for your spreader. Make
sure typical baffles/plates/shields are installed.
Output percent value = 35.
To be recorded and used
during GATE calibration if
using variable gate.


If you are continuing to “Measured Dump” from “Trim Adjustments” section,
please check that vehicle still has close to a typical load. It is important the feeder
stays fully supplied with material during measured dump.
If you have not set/checked trims, please do so before continuing with measured
DUMP.
o If you have not checked trims this season and are re-calibrating the vehicle
for any reason, The Make/Check Trim Adjustment section of this manual
should be followed. The vehicle should be filled with a typical load of
material when setting trims.
16
ACS CALIBRATION MANUAL Rev. E SG07230014
o If this vehicle has never been calibrated or has recently had the “EEPROM”
cleared by the Administrator; the feeder trims MUST be set first!
 The controller WILL NOT calculate proper default Open Loop values
needed in event there is a sensor failure, if there are NO “Pulse/Minute”
values presently saved under the “Trims” screen.
 By default from the factory or after an EEPROM clear, these values are
set to zero (0) and must be set and saved with REAL values achieved
after completing the Make/Check Trim Adjustment section of this manual.
 If the Vehicle does not have a working feeder sensor for CLOSED LOOP, the
Measured Dump procedure cannot be completed.
2. Familiarization of Measured Dump Procedure
 The vehicle must be weighed twice; once before, and once after the Measured Dump
procedure. When it’s necessary to re-weigh the vehicle after “Measured dump,” be
sure the measurement is recorded in the same manner as previously to measured
dump, i.e., Driver is in the vehicle both times the weight is recorded.
 Weigh the vehicle loaded with material.
o Record vehicle weight here:_________
o Driver IN or OUT of vehicle (circle one)
o Note: A simple bathroom scale and bucket can be used to weigh material if a
truck scale is unavailable. See instructions following on next pages.
 Once again back the vehicle up as close to the salt pile as possible.

Safety first!
Use caution! Please note the following bullets and study the diagram below:
 WARNING: Keep all personnel clear of the vehicle and mechanism before
continuing. The feeder is LIVE while in measured dump!
%



Full control of feeder is achieved using the display keys.
Operator panel is disabled except for Spinner knob. The Spinner knob is usable
between 0-100% trim while in measured dump to help move material away from the
truck and feeder. By default, the Spinner is ‘OFF’ when measured dump is started.
Turn the Lane knob one click clock-wise to start the spinner turning. It can be
turned off with the Lane knob while measured dump is active.
Double check that there is plenty of material loaded onto the feed mechanism.

ACS CALIBRATION MANUAL Rev. E SG07230014
3. Starting Measured Dump!
 NOTE: VARIABLE GATE: If using a variable gate, you MUST run the same
percent of output (Rate) for the duration of measured dump and all gate dumps. You
CANNOT vary the output while running the measured dump. Use up ▲ arrow to
reach a suitable value like 35% as quickly as possible and keep it there until it’s
necessary to stop the output.
 If running FIXED GATE, you can run the output at any rate that you are
comfortable with. It is OK to vary the output from 5-100% at any time.


Use Left arrow on the display panel to Pause measured dump at anytime, i.e., the
feeder starts to dig a hole. DON’T USE ESCAPE KEY OR YOU WILL HAVE
TO START OVER.
 Run measured dump as long as possible. It is normally sufficient to run the measured
dump for 2-5 minutes or until 1500-2500 pounds [700 – 1200 kilograms] of salt have
been dispensed. Usually a pile about 3-4 ft. high by 5-7ft. wide [1 meter high by 2
meters wide] is sufficient. If using a Truck scale to weigh vehicle, it makes sense to
dispense as much as you can, but if you are using a bucket and shovel, you may wish
to do less, perhaps 1000 lbs or [450 kilograms], which would require you to fill 16 18 buckets.
 Stop the measured dump and drive the truck to the scale and re-weigh. Be sure same
driver is in vehicle if he was in the vehicle when it was weighed previous to measured
dump. Record the vehicle weight________.
 Record Feeder % used during measured dump. IF CALIBRATING A VARIABLE
GATE LATER IN THIS INSTRUCTION you will need to know the percent value.
Feeder (fixed) percent used._________% feeder.
 Record Gate opening (in inches) OR [centimeters] used during measured
dump________inches. Or _______centimeters.

4. Getting Material weight dispensed using a simple Bathroom scale & bucket:
Alternative weighing method: Use Bathroom scale/bucket/shovel to weigh material.
 Note: If a truck scale is unavailable a simple bathroom scale can be used:
o Create a pile roughly 3ft. high by 5-6 ft. [1 meter high by 2 meters wide].
o Weigh the empty bucket. Record the weight in the blank space provided below
for “empty bucket weight.”
o Shovel the material into a 5 gallon bucket.
o Weigh the first FULL bucket. Record it below.

your bucket count otherwise. Be sure to fill each bucket to the brim and level it
off. If you end up with a partial bucket at the end, you can weigh the bucket and
subtract the bucket weight as you did above for the FULL bucket. Did I already
say to write down your buckets or you’ll lose track? After all the material has
been measured by bucket, add up your slash marks for total buckets. Use the
equation below. Add the partial bucket weight as well.

OPEN LOOP MEASURED DUMP (NO FEEDER SENSOR INSTALLED)
Note: Proceed to CLOSED LOOP MEASURED DUMP if you have a feeder sensor installed.
1. Checklist for (open-loop) Measured Dump
 Using Variable height gate? If performing a measured dump with a variable height gate:
Set the gate at the most typical opening (calibrate height), perform the measured
dump, then continue on to section: GATE CONTROL: CALIBRATING
VARIABLE GATE.
o Note: The smallest gate increment is (.5). e.g. 4.5 inches or 11.5 centimeters.
 Using a Fixed Gate? Make sure gate is fixed at proper opening for your spreader. Make
sure typical baffles/plates/shields are installed.
 Note: A simple bathroom scale and bucket can be used to weigh material if a truck
scale is unavailable. See instructions below and on the next pages.
2. Familiarization of measured Dump Procedure
 The vehicle must be weighed twice - once before and once after the Measured
Dump procedure. When it’s necessary to re-weigh the vehicle after “Measured
dump,” be sure the measurement is recorded in the same manner as previously to
measured dump, i.e. Driver is in the vehicle both times the weight is recorded.
 Weigh the vehicle loaded with material.
o Record vehicle weight here:_________
o Driver IN or OUT of vehicle (circle one)
o Note: A simple bathroom scale and bucket can be used to weigh material if a
truck scale is unavailable. See instructions following and on next pages.
 Once again back the vehicle up as close to the salt pile as possible.
 Navigate to the measured dump screen shown below using the arrow and F3 keys on
the display.
 Be sure Feeder is loaded with Salt.

Safety first!
Use caution! Please note the following bullets and study the diagram below:
 WARNING: Keep all personnel clear of the vehicle and mechanism before
continuing. The feeder is live while in measured dump!
 CAUTION! FEEDER WILL RUN AT MAX TRIM FOR OPEN LOOP
MEASURED DUMP.


Full control of feeder is achieved using the display keys.
Operator panel is disabled except for Spinner knob. The Spinner knob is usable
between 0-100% trim while in measured dump to help move material away from the
truck and feeder. By default, the Spinner is ‘OFF’ when measured dump is started.
Turn the Lane knob one click clock-wise to start the spinner turning. It can be
turned off with the Lane knob while measured dump is active.
 Double check that there is plenty of material loaded onto the feed mechanism.
3. Starting Measured Dump!
 If using a variable gate you must run the same percent of output (Rate) for the
duration of all dumps. Open loop measured dump runs the output at MAX TRIM;
therefore when the gate is calibrated it must be run at max trim as well (100%).

GATE CONTROL: CALIBRATING A VARIABLE GATE
1. About Variable Gate:
Feeder must be run at a fixed speed while performing ALL gate height calibrations.
 If running closed loop, you should have recorded the Feed percent used during
measured dump in the “CLOSED LOOP MEASURED DUMP SECTION.”
 Gate Control - Gate control can be used with a sensor (closed loop) or without a
sensor (open loop).
Change “Gate Control”
variable to “Yes” if using
variable height gate.
Gate settings menu will
become selectable.
Foreword: To obtain an accurate variable with a gate type spreader, the following guidelines
should be used.
 The Feeder drive measured dump must be performed regardless of using variable
Gate or not. If you have not done a measured dump for the feeder drive, that should
be performed first. Calibrate height Pounds/pulse or [Kilograms/pulse](closed loop)
or Lbs/Min or [Kg./Min.](open-loop) is entered under the measured dump screen in
the Feeder Settings/Valve Setup/Measured Dump menu. Other gate settings are entered
under the Gate Settings menu detailed herein.
 The vehicle should be warmed up, including the Hydraulic system, to typical
operating temperature.
 Use a stop-watch to time equal dumps if possible (see below).
 The Vehicle should be loaded to its typical load capacity.
 Weigh the vehicle with the driver in the truck.
 The Feeder must be run for settings of:
 “Low gate Dump,”
 “Calibrated height” (done during MEASURED DUMP).
 “High dump height.”
 Dumping for ALL heights must be run at the same feeder speed percent used during
Measured Dump to obtain an accurate calibration. If you just performed a measured
dump, you recorded the calibrate gate opening in inches and also the feed output percent
used during measured dump. If it’s been more than a few days since the measured
dump was performed, the feeder measured dump must almost always be reperformed even if it was previously calibrated because all three dumps should be
performed under the same conditions.
24
ACS CALIBRATION MANUAL Rev. E SG07230014
2. How to enter Gate Settings
Enter all gate opening
measurements
Enter Pounds/Minute [Kilograms/Minute] values


MAXIMUM HEIGHT: Enter the maximum height the Gate is capable of opening.
CALIBRATE HEIGHT: Enter the height the vehicle’s Feeder was calibrated at.
You should have recorded it under measured dump above.
 LOW GATE DUMP: This is the lowest gate setting in which the vehicle’s spreader
will be operated.
 LOW GATE LBS/MIN----HIGH GATE LBS/MIN [Kilograms/Minute]: These
values are obtained by running the feeder for a period of time at a fixed rate to
determine the Lbs/Min [Kg./Min.] value at the Low Gate height (or high gate
height) i.e., one minute at 50% output. If running Open loop (no sensor), the feeder
must be run at 100% trim because that is where open-loop measured dump operates.
3. Running the Feeder for High & Low Gate Dumps
 Use MANUAL OPERATING MODE.
 If running closed loop (with sensor), adjust output rate (displayed on the operating
screen) to SAME output feed percent recorded PREVIOUSLY during CLOSED
LOOP MEASURED DUMP.
 Adjust Gate to Low setting (or high setting if running High Gate Dump).
 Back vehicle up close to salt pile.
 Make sure feeder is loaded with material same as it was done during measured
dump. (All the same shields and baffles should be in place.)
 In OPERATING (MANUAL MODE) Be sure control is in Pause.
Note: Reference the operator’s manual if you are not familiar with the
operation of manual control.
 Set feed rate to feeder output percent used during measured dump. If running
Closed-Loop you should have recorded the percentage above after you
completed the measured dump procedure. If you calibrated Open-Loop, adjust the
output to 100%.
 Caution! Be sure all personnel are well clear of the vehicle.
 Start the stopwatch and remove pause at the same time.
 Run the dump for exactly 1 minute or longer if you desire a more accurate
calculation. Divide the dispensed final weight by number of minutes the test was
run to achieve the Lbs/Min. [Kg./Min metric mode] value needed for calibration.
Be sure the feeder does not dig holes, or else you will need to repeat the entire
process again. (Just be sure to put the material back in the truck to get the truck
back to its original weight.) PRESS PAUSE AGAIN AT 1 MINUTE or when a
sufficient amount of material has accumulated!
 If the test is run longer than one minute be sure to convert minutes and seconds to
whole minutes. e.g. If test is run for 1 minute 15 seconds the equation would be: 15
seconds/60 seconds=.25 minutes or 1.25 minutes.
25
ACS CALIBRATION MANUAL Rev. E SG07230014


 Weigh the vehicle again (with the operator) subtracting the new weight from the
original weight before the dump process, or else if you are measuring with a
bathroom scale and bucket, follow the procedure described under “Bathroom
Scale Method” within the measured dump procedure. Record here the Low
Gate Lbs./Min._______or Kg./Min.________; then enter the value under
Feeder Drive “Gate Settings”.
Repeat the process above for High gate dump. Record High Gate
Lbs./Min.______ or Kg./Min._______; then enter the value under Feeder
Drive “Gate Settings”.
That should be it. The Gate is calibrated!

OPEN LOOP/CLOSED LOOP PERCENT SPINNER


Percent mode spinner is utilized when the operator needs complete control over the
Spinner speed. Percent mode spinner has no interaction with the Feeder. See Lane
Control Spinner below if you wish to have the feeder controlled by number of Spinner
lanes active (Lane control).
There’s no calibration necessary for PERCENT mode spinner. It is only necessary to
make sure trim levels are set properly under load.
o Load the truck with material if it’s not already loaded from performing a
measured dump.
o Navigate to Spinner Setting menu using the display arrow and F3 keys.
Follow the illustrations below for a guide.

OPEN LOOP LANE CONTROL SPINNER




Lane control is used when it’s important to keep uniform Lbs/Lane mile (Lb/LM)
[Kg/LnKm metric mode] across all lanes while the truck is dispensing material. The
spinner controls the feeder output. As the spinner is changed from 1 to 2 lanes, the
feeder output is automatically doubled or tripled or quadrupled if running 4 lanes.
Perform Trim adjustments as detailed in the previous section for Open/Closed Loop
percent mode spinner.
You must log-in as Administrator to change the Spinner Mode Type to “Lane” if the
Spinner menu does not look like it does below (for technician log-in).
NUMBER OF LANES should be chosen with the following conditions applied:
o In LANE MODE; The Spinner controls the Feeder. Setting “Number of
Lanes” to (4) allows the driver of the vehicle to select 1 to 4 lanes. The
Feeder and Pre-Wet must be capable of putting out 4X the displayed feed
rate set on the operating screen. If the feeder cannot keep up with the
requirement, the operator will get “FEED RATE LOW – SLOW DOWN!”
error in operating mode, and will see similar errors for the Pre-Wet as well.
Change # of Lanes to
appropriate lanes for
your needs. 1-2-3 or 4.
Note: For open-loop operation the “Lane %
Calibration” variable should be boldly high-lighted.


CAUTION! Keep all personnel clear of the mechanism. The Feeder and Spinner are
active when adjusting “Lane % (percent) calibration”. The Feeder will activate by
turning the feeder knob clockwise 0-100% of valve trim while adjusting the Lane %
calibration value.
Adjust Lane % Calibration up/down with the display arrow keys for (1) lane of
coverage. It may be necessary to drive the vehicle so you may account for material
scatter. USE CAUTION! Be sure feeder is loading the Spinner with material (salt)
while calibrating lanes.
o If running (2) lanes you must keep “Lane % Calibration” below 50.
o If running (3) lanes you must keep “Lane % Calibration” below 33.
o If running (4) lanes you must keep “Lane % Calibration” below 25.
Adjust for exactly (1)
lane of coverage.

ZERO VELOCITY SPINNER
If you don’t have a Zero Velocity Spreader installed on your vehicle please disregard this section.
1. Basic Operating principle of Zero Velocity:
 Material being distributed to the road surface is accelerated at a speed equal to the
current vehicle speed in Miles Per hour or [Kilometer per hour metric mode] but in
opposite direction to which the vehicle is traveling therefore canceling material
velocity in relation to the road surface.
 As material contacts the road surface it will not tumble and scatter; therefore, it’s
possible to place material in an exact location, such as on the crown of the road
reducing the amount of wasted material that tumbles to areas of little usefulness.
2. Prep and Setup of Zero Velocity Spinner
 The MPH input must be calibrated first. Anytime the MPH input is calibrated the
ZV (zero velocity) spreader must be re-calibrated.
o To test calibration of the MPH [Km/H metric mode] input drive the vehicle
observing the ACS MPH [Km/H metric mode] display it should track with the
vehicle speedometer.
 Setup for ZV by changing the “Spinner Settings” menu “Spinner Mode” to “Zero
Vel.”
Note: This can only be done by the Administrator log-in if ZV is not already set-up
 Change Spinner sensor to Yes (closed-loop) or No (open-loop)
Note: This can only be done by the Administrator log-in if ZV is not already set-up
These settings
can only be
modified by the
Administrator
************************************************************************************
**This point forward, all illustrations will be detailed as seen through the Technician log-in**
************************************************************************************
 The hydraulic system should be brought up to normal operating temperature. This is
especially important if performing an Open-loop calibration!
 The Vehicle should be loaded with material most typically spread by the ZV
spreader.
o If running variable gate, have the gate adjusted to the most typical opening.
Be sure the current height is displaying on the operating screen.
 All motor sensors should be wired and functional for closed-loop operation
 Adjust the ZV shoot for typical angle and elevation.
CONTINUED ON NEXT PAGE….
30
ACS CALIBRATION MANUAL Rev. E SG07230014
3. Trim Adjustment
 Perform Trim adjustments as detailed in the previous section for Open/Closed Loop
percent mode spinner after reading the bulleted items outlined below.
o Trim adjustments are best done at the salt pile to help minimize mess.
o Spinner MIN TRIM should be set as low as possible. However the ZV
spreader should be running fast enough to keep clearing material out of it.
Run the feeder close to minimum speed by clicking the Feed knob clock-wise
one click.
o Sensor pulses should display from the motor sensor if running closed-loop.
o If running open-loop you’ll need to adjust the trim and check what it’s
actually doing on the back of the truck. If someone can help you it makes the
process work more efficiently.
o MAX TRIM should be adjusted with NO granular material running through
the ZV mechanism. This is because we wish to find the absolute maximum
velocity the ZV can run under NO load or minimum load; however be sure
NOT to exceed the mechanical limits established by the ZV manufacturer.
4. Manual entry of calibration settings
 Proceed to “Valve Setup”, then “Zero Vel. Calibration”
 If calibration values “Pulses/Minute”(closed-loop) or “Open Loop Factor” (Openloop) and “Vehicle Speed” are previously known they may be manually entered
Select the Zero Vel Calibration menu to access
calibration screen for “Low” and “High Speed”
calibration points
“Pulses/Minute” or “Vehicle Speed” can be manually
entered or modified at any time as shown, using the
display up/down arrow keys. Be sure to press F3 key
“Accept”, to save modified values.

Manual Cal value adjustment:
o Cal values can be adjusted up or down to fine tune performance.
 Low Vehicle speed/Low material velocity adjustments should be made to
“Low Speed” values.
 High Vehicle speed/High material velocity adjustments should be made
to High speed values.
o Increasing “Pulses/Minute” value or decreasing MPH [Km/H metric mode]
value increases material velocity.
o Conversely decreasing “Pulses/minute” value or increasing MPH [Km/H
metric mode] value decreases material velocity.
31
ACS CALIBRATION MANUAL Rev. E SG07230014
5. Getting ready for calibration
 It is necessary to calibrate a 2-point “Low Setting” and a “High Setting”. See
illustrations and instructions below.
Note: “Low Speed” values shown.


Use display ▲▼ arrows to control ON/OFF control
and speed in 5% increments of ZV spreader.
Left arrow or ESC. Key aborts the ZV operation.
Pulses/minute value from sensor for this calibration point.
Current vehicle speed in Miles Per Hour for this calibration point.
(Km/H if running Metric mode)

The rest of the calibration involves driving the truck.
o Find a low to no traffic area for testing if possible.
o The ZV spinner will activate with the next step.
o Open-loop ZV calibration is performed the same as closed-loop so both are
covered here under the same text. The only difference is the “Open-loop Cal
factor” is generated internally based on valve trim percent. Changing the
“Open-Loop Factor” or “Vehicle Speed” value have the same effect on
Open-loop control as “Pulses/Minute” and “Vehicle Speed” do to Closedloop control as described previously for “Manual Cal value Adjustment”.
Note: Open-loop ZV Calibration displayed at the
top of the screen.
“Pulses/Minute” is replaced by “Open-Loop
Factor” when ZV is configured for “No” sensor
o If calibrating a closed-loop system, open-loop values are automatically saved
simultaneously while saving closed loop values. Open-loop values are
necessary in event sensor failure occurs in operating closed-loop mode. The
number value open-loop “Open loop Factor” is identical to the
“Pulses/Minute” value for closed-loop systems.
6. Low Speed Calibration
o Typical low speed calibration would be in the 5-8MPH range. Adjust the
“Valve Drive Adjust” to 5% using the display arrow keys.
o Turn the Feeder knob clockwise one click to start feeding material into the
ZV spreader.
o Drive the vehicle and locate a speed where material ZV is reached. A spotter
car following the truck works well. A radio can be used for communication
ideally, but something as simple as flashing headlights or honking the horn
by the spotter car when the correct speed is observed can be used.
o Press the display F3 key to save values.
HIGH SPEED CALIBRATION CONTINUED ON NEXT PAGE….
32
ACS CALIBRATION MANUAL Rev. E SG07230014
7. High Speed Calibration
 Repeat the same procedure for High Speed calibration. Use display Page Dn / F2
key or arrow keys to navigate to the ‘High Speed page’. It will be detailed as shown
below.
o The High speed value should be calibrated to the most common vehicle
speed traveled. e.g. 30-35 MPH.
o Increase feeder output by turning the feeder knob another 10-15 clicks to
approximately 75% of full granular output capability. This gives a more
realistic load to the ZV mechanism.
o ZV Cal values can be adjusted manually if needed after the ZV has been
tested in operating mode. This is especially true for Open-loop control. It is
recommended that if calibrating closed-loop that open-loop control be tested
by disconnecting the spinner sensor and testing the failure into open-loop.
Adjust cal values accordingly if necessary. Adjusting cal values while running
open-loop will only improve the responsiveness of closed-loop as well.
Note: If PPM (pulses/minute) stop increasing with increases to the “Valve
Drive Adjust” value, then you have already reached maximum hydraulic flow
and ZV velocity and you need to decrease valve drive until the PPM drops
off slightly. This also sets the maximum speed at which you will be able to
operate the ZV spreader. In event max speed is exceeded while in normal
‘Operating Mode’ the Operator will receive a “Spin Rate low –Slow Down!”
message on the display.
Note: “High Speed” values shown
8. Operator (override) LANE knob adjustment range
 Set Operator Knob override adjustment range.
o 10% = 10% of valve trim between min and max trim. This is +/_ from
center cal position. So total range is actually 20%.
o A typical value would be 10%. 0% = Gives no adjustment to the driver.
o When the ‘Lane’ knob is adjusted in Operating Mode the ZV MPH [Km/H
metric mode] display will show changes in material speed as the knob is
increased or decreased.

CLOSED/OPEN LOOP PRE-WET CALIBRATION
1. Checklist: Before starting calibration.
 Tanks with liquid in them. Use caution if using straight water. Water will freeze
causing major damage to all system components. If water is to be used for
calibration, be sure to flush system thoroughly with windshield washer fluid when
calibration is completed to remove all water.
 All typical plumbing and nozzles must be attached. Be sure nozzles are clean.
 Liquid Pump Bypass valve (inside pump enclosure) must be set prior to calibration.
Contact your local Freedom Systems Salesperson if you have questions about how to
set the valve.
 Move the vehicle to a location where it’s ok to dispense liquid materials.
 Electric pump motors can be driven directly by the ACS output module; however
Valve Frequency (illustrated below-right) MUST be set for 300Hz. and output
current will automatically be internally limited to 6 amps.

2. Closed-loop Pre-wet calibration
 Navigate to the Pre-wet Valve setup screen shown below using the display’s arrow
and F3 keys on the display panel. Use the illustrations below as a guide.
 Set the flow-meter K-Factor
Note: Flow-meter is set to
“YES”. This is ClosedLoop operation.

Enter directly: The flow-meter K-Factor.
Normally found on a Tag located on the
flow-meter. This is entered as (P)ulses (P)er
(G)allons US even when in Metric mode.
Navigate to the “Valve Trim Adjust” screen shown below using the display’s arrow
and F3 keys on the display panel. Use the illustrations below as a guide.
Typical Min Trim setting and pulses
feedback For Hydraulic Stack-driven
pre-wet.
Typical Max Trim setting and pulse
feedback for Hydraulic Stack-driven
Pre-wet. Do not to exceed 40% max
trim value for typical Hypro type
Hydraulic motors.

Adjust min trim for the lowest pulses possible pulses: 300-600. Press display F3 key
to “Accept”; SAVE the value.
 Exit in and out of min trim value to make sure min trim setting starts the PreWet motor each time
 Adjust Max Trim for the highest pulse count (sensor feedback) without raising the
Max trim value above where pulses stop increasing. If this happens the controller
response while operating in closed-loop is slowed down and the Open loop control
does not work accurately in event the Flow-meter fails.
 If using Hypro motor on pre-wet pump do not exceed 40% trim for Max.
 It is not recommended to use Auto-trim for Pre-Wet trim calibrations due to excess
flows exceeding the manufacturer’s rating of the hydraulic pump motor (4 GPM).
Max trim for a typical Stack-driven Pre-wet should be no more than 40%.
3. Fault time-out (closed-loop only)
 While in the Trim screens (see above illustrations), set a fault time-out for the ACS
control to switch into Open-Loop mode.
 Should be adjusted for a value between 1 and 30 seconds.
 Time-out operation important for default Open-Loop operation to maintain a
regulated output in event of sensor failure.

a measured volume in a given time to derive your max
GPM (G)allon (P)er (M)inute value.

Adjust min trim for the lowest Pre-wet pump speed that can be observed without
stalling. Press display F3 key to “Accept”; SAVE the value.
o Exit in and out of min trim value to make sure min trim setting starts the
Pre-Wet motor each time.
 Adjust Max Trim by watching for Max flow exiting the Pre-Wet nozzles without
raising the Max trim value above where flow stops increasing. If this happens, the
controller will not operate open-loop control very accurately.
o One method to measure the max GPM value on open-loop pre-wets would
be to re-direct the nozzle output into a 5 gallon bucket. Time how long it
takes to fill the bucket. Divide 5 gallons e.g. 5 divided by 1.5 minutes =
3.33GPM.
o If using Hypro motor on pre-wet pump do not exceed 40% trim for Max.
5. ON/OFF open-loop Pre-wet calibration
 On/Off Pre-wet used for Hydraulic ratio Pre-wet systems. Or single speed electric
motors or relays.
 Output runs at Max trim value. Max trim typically set to 100%.
 Output turns ON/OFF with Feeder, ground-speed (MPH) [Km/H metric mode], and
Tank empty inputs.
Set frequency to 300% for
electric motors, relays and
ON/OFF coils.
Set max trim to 100%
typically for ON/OFF Prewet. Used for ON/OFF
coils, motors and relays.
Current limited to 6 Amps

Reduce trims until pulses just start to drop, then increase again
just until max pulses are achieved again. Press F3 to save.


Adjust min trim for the lowest possible pulses: 300-600. Press display F3 key to
“Accept”; SAVE the value.
 If running open loop (no sensor) adjust min trim to point where pump-motor is
running as slow as possible without stalling.
 Exit in and out of min trim value to make sure min trim setting starts the AntiIce pump-motor each time
Adjust Max Trim for the highest pulse count (sensor feedback) without raising the
Max trim value above where pulses stop increasing. If this happens the controller
response while operating in closed-loop is slowed down and the Open loop control
does not work accurately in event the Flow-meter fails.
 Read caption above next to illustration showing Anti-Ice trims setting.
 It is not recommended to use Auto-trim for trim calibrations due to excess flows
exceeding the manufacturer’s rating of the hydraulic pump motor.
