Juniper Systems Classic GG - Manual (Page 2)

Test Weight Chamber Volume
1. Select Setup (F3)>Hardware Setup>Classic GrainGage Setup>Chamber Volume.
2. Default values for the chamber volume are as follows.
Chamber Size Cubic Inches Cubic cm.
3.5 liter 209 3441
1.5 liter 89 1458
¾ liter 40 655
3. Cycle a grain sample, with a known test weight, through the GrainGage.
4. Grain sample needs to be large enough for at least three full cycles. (15-18 lb. for a three liter chamber, 8-9 lb. with a 1.5 liter, & 5 lb.
with a ¾ liter.)
5. Run the sample though the GrainGage in harvest mode three to five times and average the readings.
6. Calculate the new test weight chamber by using the following the formula:
New Chamber Volume =Measured Test Weight / Actual Test Weight * Chamber Volume
7. Enter the new Chamber Volume value and press Save (F4).
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
Timer Settings
1. Select Setup (F3)>Hardware Setup>Classic GrainGage Setup>Timers.
• Open State Time—Value indicates how long each gate will remain open allowing grain to flow through.
• Clear Delay—When the level of the grain is no longer high enough to trigger the Open Level and Close Level settings, the Clear
Delay starts. When the Clear Delay timer expires the system can process a end-of-cycle sequence. The Clear Delay starts after
pressing ENTER to save the data.
• Weigh Time—The amount of time data is collected and averaged to determine the actual weight reading.
HM 800 Default Settings Open State Timer – 0.6 Clear Delay Timer – 1.0 Weight Time – 0.8
Classic GrainGage 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 (not exceeding 5lb./2.27 kg) onto the weigh pan. Verify that the system reads the same
weight. Remove weight and verify the system zeros out.
