Conveyor with automatic lift
Two outputs raise and lower the conveyor head. A flap sensor on one input raises it for you as the heap builds, on a button you arm from the armrest. Six channels spare and seven inputs still free.

Wire it
Every channel wires the same way. Battery positive taps the COM screws in use; each NO goes out to one load, and the load returns to chassis ground.
Two outputs and one sensor. The flap wires to DI1 on the module's own input header, and a sensor that signals with +12 V needs the input COM tied to ground.
| CH | Icon | Name | Function | Mode |
|---|---|---|---|---|
| CH1 | LIFT + | Lift raise | MOM | |
| CH2 | LIFT - | Lift lower | MOM |
Name it
One button on the terminal is a name, an icon, the outputs it switches, and MOM or TOG. That is all there is to set up. No laptop, no software.

Drive it
The finished dashboard. Assign the same functions to armrest or joystick buttons through the tractor's AUX-N menu and you never touch the screen again.

CH3, CH4, CH5, CH6, CH7 and CH8 are not used on this machine, so they keep the terminal's default names. Drawn from the channel map above, not a photograph of an installation.
Let the sensors do it
Each sensor gets one rule: what it drives, and what counts as active. You arm the rule from the terminal or from an armrest button, and it stays armed until you disarm it or take manual control.
The sensors are optional. Everything above already works from the buttons on their own, and plenty of machines are wired with the inputs left empty. Add them when you would rather not hold a button while you watch something else.
| Input | Sensor | Mode | Drives | Armed by |
|---|---|---|---|---|
| DI1 | Flap sensorAn on delay of a few tenths keeps a fluttering flap from lifting the head, and an off delay stops it hunting when the flap sits on its trigger point. | FOLLOWOutput on while input active | CH1 | AUTOLIFT |
One tile arms DI1. A tile takes a name and an icon exactly like a relay button does. Nothing arms itself: not at power-up, not after a preset change, not when the terminal reconnects. Touch a manual control that overlaps an armed tile and it drops out on the spot, and it never comes back on its own. This is protection for normal operation, not a safety function.
Variations
The same machine, wired differently.
Lower on a sensor too
A second flap or proximity sensor lowers the head again. Put both on one tile with INTERLOCK, and if they ever demand at once nothing moves until they disagree.
2 outputs · 2 inputsEnd stops
Two limit switches wired normally closed and set to INVERT and BLOCK, so a broken wire stops the automation rather than quietly removing the limit. They bound the automation only; your buttons still reach the ends.
2 outputs · 4 inputsLowering under its own weight
Where the head drops on gravity through a single-acting valve, raise is the only powered direction.

Now do yours
Same module, same three steps. What hangs off the channels is your call.

Will this work on my tractor?
Any ISOBUS tractor with a Virtual Terminal, whatever the make. The in-cab ISOBUS connector is the same on every brand, so there is nothing to match to yours.
Do I need a weatherproof enclosure?
Outdoors, yes. The bare module is IP20, which means in-cab or panel mounting only, so on an implement it goes in an IP65 box you supply yourself.
Can I change the button names and icons myself?
Yes, from the tractor screen. A button takes a name of up to 8 characters and an icon from the module's set, and both show up in the tractor's AUX-N assignment menu as well. The WiFi interface is for diagnostics, testing outputs and firmware, not for setup.
What if the machine needs more than 8 outputs?
There is a 32-channel module: one unit with 32 relay channels, everything else the same. It has no digital inputs, so a machine that also needs sensors takes a second 8-channel module instead.
