ACS CALIBRATION MANUAL Rev. E SG07230014 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.
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.
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: ...
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.
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”...

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.
ACS CALIBRATION MANUAL Rev. E SG07230014 o Subtract the weight of the empty bucket from the full bucket weight completing the equation below. The result is the material weight of one bucket FULL - minus the bucket weight. Record the weight. Write it down or you will forget it. o Full bucket weight._______(-)empty bucket weight ______=Material weight________ o Now fill and count each bucket of salt using the //// //// “slash then count”...
ACS CALIBRATION MANUAL Rev. E SG07230014 OPEN LOOP MEASURED DUMP (NO FEEDER SENSOR INSTALLED) if you have a feeder sensor installed. Note: Proceed to CLOSED LOOP MEASURED DUMP 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.
ACS CALIBRATION MANUAL Rev. E SG07230014 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! ...
ACS CALIBRATION MANUAL Rev. E SG07230014 If USING VARIABLE GATE, record Gate opening (in inches) [centimeters] used during calibrated dump________inches/or _______centimeters. Original weight (recorded above)_______(-) new weight (after dump)______ = total weight of material dispensed.________ Key in the weight of the material for “Pounds Dumped” or [Kilograms Dumped] variable.
ACS CALIBRATION MANUAL Rev. E SG07230014 5. Manually enter Pounds/minute [Kilograms/Minute] . It’s not necessary to run measured dump if the LBS/MIN value is known. It can be manually entered at any time. This could be necessary if for any reason calibration variables may have been lost because the valve output module has been replaced or the EEPROM has been cleared by the administrator.
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.

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”...
ACS CALIBRATION MANUAL Rev. E SG07230014 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).
ACS CALIBRATION MANUAL Rev. E SG07230014 OPEN LOOP SPINNER LANE CONTROL 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.
ACS CALIBRATION MANUAL Rev. E SG07230014 CLOSED LOOP SPINNER LANE CONTROL Lane control is used when it’s important to keep uniform Lbs/Lane mile (Lb/LnM) [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 lane to 2 lanes, the feeder output is automatically doubled or tripled or quadrupled if running 4 lanes.
ACS CALIBRATION MANUAL Rev. E SG07230014 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.
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.
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.
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.
