Inspect the GrainGage

After you install the GrainGage system (and at the beginning of each harvest season thereafter), perform a mechanical inspection and check the system diagnostics in Mirus.

Perform a Mechanical Inspection

Mechanical Validation

  • Before using the system for the first time, ensure the shipping stops have been removed. (See Remove the Shipping Stops.)
  • Check the plot bucket for proper alignment. Verify that it is resting on the load cells and weighing properly. (See Perform Daily System Checks.)
  • Check all cables and electrical connections. Verify that they are secure and have not come loose.
  • Inspect all cables for mice damage.
  • Ensure the cables and hoses are securely tied on each side to minimize movement. Cables and hoses should not have any tight bends or kinks.
  • Turn off the air and verify that all gates fully open and close at the end of the stroke. HarvestMaster recommends keeping some spare gate cylinders on hand for needed replacements.
  • If you are using the EM sensor, clean the EM moisture blade.
  • If you are using the SCiO Sensor, clean the glass dome on the SCiO sensor with glass cleaner and a non-abrasive microfiber cloth.
  • Turn on the air and set the regulator to 75 psi. (The system supports air pressure between 75‒85 PSI.) Check for air leaks throughout the system while opening and closing the gates.
  • Ensure all actuators operate normally and cycle smoothly. 
  • Make sure the separator cup moves up and down freely.
  • Clean the actuator slide rods with a damp cloth. Do not lubricate or clean the actuator slide rods with WD-40 or other penetrating lubricants. This can degrade the internal seals. 

Operational Validation

Check the following weight and moisture calibrations in Mirus.

  • Slope and motion
  • Weigh bucket
  • Test weight load cell
  • (Option) SCiO NIR Sensor self test
  • Moisture chamber

For detailed instructions, refer to the Mirus for H2/H3 Classic GrainGage User Guide.

Check the Diagnostics in Mirus

As part of the initial GrainGage setup (and periodically thereafter), use Mirus Diagnostics to manually check the weight, moisture, test weight, and actuator diagnostics. For information on diagnostics in Mirus, refer to "GrainGage Diagnostics & Alerts" in the Mirus for H2/H3 Classic GrainGage User Guide.
