The ESD module is composed of a Driver control unit and a coupled Brushless motor. Installed on each sowing element, the ESD modules allow the rotation of the seeding disc to be adjusted in a way that is proportional to the feed-rate, in relation to the sowing distance set on the Virtual Terminal.
The ESD modules are connected to each other via CAN BUS network and, thanks to the ECU Gateway that manages them, it simplifies interfacing with the rest of the system (both standard MC and client’s custom). Each device is designed to be connected directly to the 12V battery via protection fuse. An enabling signal eliminates power consumption when the system is off.
There is also an input that makes it possible to integrate the seed counter photocell in the ESD module, reducing the complexity of the wiring.
Using the ESD modules, it is possible to set-up seed drills up to maximum 8 rows using the tractor’s normal battery. For more than 8 rows, you must install a current generator on the seed drill, which is mechanically enabled from the PTO outlet of the tractor and from a coupled auxiliary battery.
Both components (generator and battery) must have appropriate power according to the number of seed drill rows.
