9.2 | Honeywell TARS-B IMU (T3H-E003)
Applicable to:
Systems where the GNSS receiver does not provide terrain compensation and/or Cross-slope control is required.
IMPORTANT: Some GNSS receivers DO NOT possess an internal IMU for terrain compensation purposes. If the receiver doesn't have terrain compensation, we highly recommend running a Cross-slope IMU on the implement in this situation so that Level COMMAND can apply the necessary terrain compensation to maintain accuracy with drain batters and other steeper slopes.
IMPORTANT: The Honeywell TARS-B IMU must be sourced from T3RRA (SKU: T3H-E003). These are supplied by T3RRA with the correct firmware and configuration to function with COMMAND.
The TARS-B IMU is used for systems where the GNSS receiver does not contain an integrated terrain compensation functionality, in addition to enabling Cross-slope control using COMMAND. The TARS-B IMU provides pitch and roll angle measurements to the COMMAND ECU for control of the implement's Cross-slope angle.
Required Parts
The IMU connects via the implement receiver harnessing.
- John Deere Front Extension harness
- TARS-B Mounting Kit (3 x M6 + Washer + Nut)
- T3H-E003 - COMMAND Inclination Sensor – TARS-B
- T3H-S001 - COMMAND Impl Adapter – Stub Junction
Mounting & Orientation
The TARS-B IMU should be mounted pointing toward the front of the machine, similar to an arrow or triangle pointing forwards. Mount the TARS-B IMU to the implement securely, preferably using a suitable bracket. If suitable bracketing isn't available, neodymium magnets are also suitable, but must have enough pull-strength that there is minimal danger of the IMU being knocked out of position.
Connection Process
- Connect the T3H-S001 adapter to the Front Extension Harness.
- Connect the T3H-E003 to the T3H-S001 stub junction using the 4-way AMPSEAL connection.
- Check that COMMAND is receiving Cross-slope angle input data - for more information please refer to the Level COMMAND manual.
Verify:
- IMU is securely aligned, mounted and connected.
