HCGG System Calibrating Guide
Load Cells—Calibration
1. Select Setup > Hardware Setup > HCGG Setup > Weight Calibration
Slope and Motion Sensor needs to be turned OFF during calibration.
2. Follow instructions on handheld screen.
EM Sensor/Test Weight Coefficient Calibration
1. Select Setup (F3) > Hardware Setup > HCGG Setup > EM Sensor > Test Weight Coefficients.
* DO NOT ADJUST Coefficient V (CoefV) and Coefficient F (CoefF). Values have been optimized.
2. To adjust your test weight reading, determine the actual test weight of the grain sample.
3. Enter the diagnostics screen by selecting Diag (F3) to see the measured test weight and then pour the grain sample into the weigh bucket
4. Use the formula below to figure out how much to adjust Coefficient Z to create the new Coefficient Z value.
Actual Test Weight – Measured test weight = Coefficient Z adjustment value
Level Detect Settings
1. Select Setup (F3)>Hardware Setup>Classic GrainGage Setup>Level Detect.
2. The Open and Close levels are settings that determine the amount of grain in the hopper needed to trigger the GrainGage to cycle. The
higher the level setting the more grain required to start the cycle sequence. Open and Close Level should never be set lower than 5.0.
HM 800 Default Settings Open Level – 10.0 Close Level – 10.0 Hopper Delay – 3.0
HCGG Maintenance Checklist
Item Process
Start System
First, start the combine. Next, turn on HarvestMaster System Console (Handheld should turn on
automatically). Finally, load FRS.
Air Pressure Air pressure should be set 60 –80 psi.
Air Leaks
If you have a reservoir air tank, turn off the combine after filling the tank. Check for air leaks on all
cylinders and solenoids. Also check solenoid exhaust port plugs for any build-up of oil or debris. If
they are caked in debris, take the exhaust port out and clean with Brake & Parts Cleaner.
Cable Connections
Ensure all cable connections are tight and there is not any debris in the connections.
Be careful when reconnecting the cables not to bend or damage any connector pins.
Debris
Blow out the Graingage at the end of every day. DO NOT use a high-pressure washer to clean
system.
Bucket Clearance
The plot bucket should be sitting firmly on the load cell tracks. Check to ensure that all cables and
air hoses are not touching the bucket. Also, check the clearance around the bucket.
Actuators Cycle Smoothly Make sure all cylinders open and close smoothly.
Weight System
Place a known weight into the weight bucket. Verify that the system reads the weight accurately.
Remove the weight and verify the system zeros out.
