CNH AFS Direct Connect / PLM Intelligence
Interface Overview
COMMAND can control Case & New Holland rear tractor valve (EHR) systems through the use of a T3H-V001 COMMAND Legacy Output Adapter. COMMAND interfaces with the Case / New Holland tractor valves by sending analog signals to the integrated valve controller, commanding either port A or port B flow of two of the rear tractor SCVs (For AFS Connect models any SCV can be linked to either of the two analog inputs).
To operate the SCVs in automatic control mode, the user first needs to arm one or both of the configured auto SCVs, and then push the respective SCV lever forward into the detent position. This will cause "AUTO" to appear on the console/armrest and a solid green indicator next to the enable toggle on the AFS Connect display, to indicate that the SCV is ready for automatic control commands.
IMPORTANT: Moving the lever will NOT disengage AUTO mode in modern case tractors, so movements based on any current valve signals will continue. Always keep this in mind during operation.
For more information on configuring COMMAND for use with Case / New Holland auxiliary rear valve control inputs, please refer to the Level COMMAND Manual.
Tractor Connection
The Case / New Holland tractor connection for analog control signal inputs via the T3H-V001 adapter are generally found in one of three locations depending on tractor mode:
- Fuse compartment
- Behind the driver seat
- Underneath the cab exterior near the articulation point for some 4WD tractor models.
Connect the T3H-V001 adapter to the T3H-C002 ECU breakout harness at the round Detusch HD series connector:
Then, connect the T3H-V001 adapter to the tractor connection:
Automatic Control Tractor Configuration Process
1. Following the connection of iGrade to the machine via the “Implement Interface” connector, the system then needs to
be configured on the armrest display.
2. Ensure that a new implement profile has been created for use with the scraper, or that the currently selected profile is
appropriate.
3. Open the “Remotes” settings tab to display remote valve configuration.
4. Set the desired remote valve outputs at the back of the tractor to the desired function (A or B).
Note: The remote valves selected for A and B should be matched to the valve connections at the back of the tractor pictured
below. We recommend setting auxiliary valve A to remote valve “Rear 1”, and setting auxiliary valve B to remote valve “Rear 2”,
which will configure remote valves 1 and 2 at the back of the tractor for use with iGrade.
5. Once the remote valves on the tractor have been set to the desired auxiliary function, the machine should now be fully
configured and ready for use. In order to engage auxiliary control, the user must ensure that the Auto Auxiliary Control
Valves A & B have been turned on in the relevant area on the “Remotes” page.
6. The “Auto Auxiliary Control Valve” can be accessed either by the hydraulic cylinder shortcut next to the display
navigation dial on the armrest, or by adding the menu to the display home page. Once this menu is accessed, turn
either or both required function to the on position and briefly push the lever until it clicks, similar to detenting a John
Deere tractor but the lever with not remain in place. Once both A and B lights are solid green, the tractor is ready to
accept 0-5V signals through the implement interface 6-pin connector.
