7.7 | Fendt ONE — 900 Gen 6/7 & 1000 Gen 2/3

Applicable to: Supported Fendt 900 Gen 6/7 and Fendt 1000 Gen 2/3 tractors using the COMMAND Fendt ONE valve interface. 
 Connection Method 
 COMMAND connects to the tractor’s rear SCV system using the T3H-V005 ISO Valve Adapter . 
 The adapter is installed inline between the tractor chassis harness and the SCV-bank harness. It connects the tractor-side and valve-side CAN networks to COMMAND through the CAN Interface connection on the T3H-C002 ECU breakout harness. 
 The tractor connection is located at the rear of the machine, on the right-hand side behind the ISOBUS socket . 
 Installation Steps 
 1. Complete the machine preparation steps in  Section 5.1 and isolate the tractor electrical supply. 
 2. Locate the SCV-bank harness connection behind the rear ISOBUS socket, shown as A in the location image. 
 (A) – SCV / Chassis Harness connection 
 
 
 
 
 3. Release the connector latch and disconnect the SCV-bank harness receptacle (A) from the tractor chassis harness plug (B) . 
 (A) – SCV Bank Harness Receptacle (B) – Tractor Chassis harness plug 
 
 
 
 
 
 
 4. Connect the  tractor-side receptacle (C) on the T3H-V005 adapter to the tractor chassis harness plug (B) . 
 5. Connect the  valve-side plug (D) on the T3H-V005 adapter to the SCV-bank harness receptacle (A) . 
 (A)  – SCV Bank Harness Receptacle (B)  – Tractor Chassis Harness Plug (C) – T3H-V005 Harness ‘Tractor’ Receptacle (D) – T3H-V005 Harness ‘Valve Block’ Plug 
 
 
 
 6. Route the adapter to the  COMMAND ECU and connect it to the Tractor/Valve CAN Interface connector (pictured right) on the T3H-C002 ECU breakout harness. 
 7. Ensure all connectors are fully seated and latched. Secure the harness clear of moving parts, hot surfaces and sharp edges, leaving sufficient slack to avoid strain on the connectors. 
 8. Keep  COMMAND disarmed and restore the electrical supply. 
 IMPORTANT: The SCV-bank harness connection and the nearby ISOBUS socket connection serve different purposes. Connect T3H-V005 to the SCV-bank harness as shown. 
 Where an ISOBUS connection is required for the installation, follow Section 5.4 using the appropriate COMMAND cab or exterior breakout harness. 
 Tractor Valve Configuration 
 
 Ensure the required tractor SCVs are enabled and unlocked using the tractor’s controls. 
 In Level COMMAND , select Fendt ONE as the valve interface. 
 Assign the required SCVs to the controlled functions, such as height and cross-slope. These assignments must match the implement’s hydraulic hose connections. 
 Verify valve communication and confirm that each function operates the intended valve in the correct direction. 
 Complete valve configuration and calibration before automatic operation. 
 
 For detailed configuration and calibration instructions, refer to the Level COMMAND Manual . 
 Operation Notes 
 To prepare the selected SCVs for automatic control: 
 
 Ensure the required tractor SCVs are enabled and unlocked. 
 Move the COMMAND Arm/Engage switch to the middle ON position to arm COMMAND. 
 Move each selected SCV’s tractor control lever into the float position to enable external control of that valve. 
 Press the momentary side of the COMMAND Arm/Engage switch to engage automatic control once the system is ready. 
 
 NOTE: For SCVs configured for COMMAND control, the lever’s float position enables external hydraulic control. It does not place the valve into hydraulic float. 
 Before handing over the installation, verify manual valve operation and demonstrate how to enable, disengage and resume automatic control. 
 IMPORTANT: To disengage COMMAND automatic control, press the momentary side of the COMMAND Arm/Engage switch . Move the switch to OFF to disarm COMMAND and disable its hydraulic control commands.
