1.1 Remove the Test Chamber
1. Turn off air and power. Follow all lockout/tagout procedures.
2. At the T fittings, disconnect the air lines that connect
the air valve to the test chamber.
3. Use a flathead screwdriver to remove the test
chamber slide gate limit switch sensor from the air
cylinder. Let it hang. Keep track of the screw.

5. Reapply the zip ties to secure the load B cable. Trim
the zip tie tails.
6. Carefully remove the two button head cap screws,
holding the chamber to the load cell.
CAUTION: Avoid stripping the screws, which have
Loctite on them, by using a good Allen wrench
and cleaning out the hex-head hole with a pick.
7. Remove the test chamber assembly from the
GrainGage.

1.2 Install the New Chamber
1. Place the new chamber in the GrainGage. Fit the
chamber lip over the fill guide.
Note: If necessary, screw in the load cell overload
protection screw four or five turns to allow the new
chamber to fit into place.
2. Apply Loctite 243 to the threads of the two button
head screws. Hand tighten the screws.

3. Check that the new chamber is properly aligned:
■The gap between the fill guide and the chamber is
consistent and even. Check the gap when the
chamber is in the down position.
■The chamber slides freely. It does not rub or bump.
4. Tighten the button head screws securely.
CAUTION: Make sure the test chamber can slide
up and down freely without contacting the fill
guide.
Note: It is possible to install the test chamber crooked
enough that it will hit the fill guide when it raises.
Lightly tighten the test chamber screws, and then
lift the chamber to check for interference with the fill
guide. With the chamber lifted, look up through the
test chamber and center it around the fill guide. Then,
tighten the test chamber screws completely.
5. If you adjusted the load cell limit screw (in step 1), use
a 5/16 wrench and adjust the screw to have a 0.006 in.

6. Attach the limit switch sensor to the air cylinder,
aligning the band about 1 in. from the end of the air
cylinder as shown.
1.3 Adjust the Air Lines
1. From the Mac-valve side, remove the bottom gate air lines that were disconnected from the T fitting.
(See step 2 in 1.1 Remove the Test Chamber on page 5.)
2. Replace the removed air lines with the 20 in. air lines provided in the upgrade kit. Route the 20 in. air
lines through the two empty grommets on the left side of the bucket.
Note: The air lines go in the grommets on the opposite side of the GrainGage from the ones you just
removed.
Use a non-corrosive lubricant to get the 20 in. air lines through the rubber grommets.

1.4 Install the SCiO Sensor
1. Position the SCiO Sensor in the new chamber. For best
results,
■Match the top of the sensor to the top of the
opening in the chamber.
■Insert the sensor at a slight angle. The top of the
sensor angled in toward the opening.
2. Tighten the four captive screws in the sensor, using a
cross pattern.
CAUTION: The screws will still tighten if
misaligned, and it’s not always obvious.
3. Check that the SCiO Sensor aligns properly with the
test chamber from the inside.
In proper alignment,
■The square portion of the sensor inserts fully
through the sheet metal.
■The sensor plastic is flush with the inside of the
sheet metal and is not recessed.
If sensor plastic is recessed or misaligned, loosen
the four screws and realign.
4. Reconnect the air lines to the left air cylinder.

head cap screw and nylock nut.
6. Route the H3 SCiO cable into the GrainGage.
7. Route the computer and DSP module cables under
the cable rail.

9. Position the computer cable end as needed. Shown
here inside the chassis.
10. Coil and secure the computer and moisture cables to
the cable rail, using the provided zip ties.
11. Attach the SCiO cable to the SCiO Sensor.

12. Secure the cable as shown with zip ties. Allow enough
slack for the test chamber to cycle without stretching
the cable. A strained cable could affect the accuracy of
the test weight.
1.5 Apply the Label
1. Install the new H3 GrainGage label.
1.6 Connect to the Computer
1. Position a 30712 Serial to USB cable from the junction cable to the cab. Follow the same path as the
CAN cable or a cleaner path if available. If needed, you can use the 31518 SCiO 15 ft extension cable
here.
2. Plug the USB end of the serial to USB cable into the USB Port of the tablet. Secure the USB end so
that it can’t vibrate out.

5. Open Diagnostics, and tap the Sensor Info tab. Check
the following settings.
■Detected sensor type: SCiO.
■SCiO code version: If unsure if this is latest version
check with HarvestMaster repsentative.
■SCiO connected: Yes.
6. Calibrate the test weight load cell, weigh bucket load
cells, and slope and motion. (See the Mirus manual for
how to calibrate.)
7. Ensure that the air lines were connected properly.
a. Open Diagnostics.
b. Open and close each gate while watching the
GrainGage to verify that the gates open and close
as expected.

2.1 Remove the Test Chamber
1. Turn off air and power. Follow all lockout/tagout procedures.
2. Check the bottom back crossbar. If the crossbar has no
notch, replace with the notched version of 26242 H2M
Crossbar.
Note: The notch is positioned on the inside of the
GrainGage facing the bottom slide gate to allow more
clearance between the crossbar and an open bottom
slide gate.
3. At the T fittings, disconnect the air lines that connect
the air valve to the test chamber.
4. Shorten the air lines to 16 in.
