Method for operating a user terminal of an agricultural machine and agricultural machine

Abstract

The disclosure refers to a method for operating an user terminal () of an agricultural machine, comprising: providing a user terminal () in a control system () of an agricultural machine, the user terminal () connected to a power supply () and configured to transmit, through a control bus (), control signals to functional elements () of the agricultural machine; applying a supply power, through a supply line, to the user terminal () with a voltage level provided by the power supply (), the voltage level being an normal operation voltage level; determining at least one of a turn-on state of an ignition device of the agricultural machine and a drop of the supply power provided by the power supply () in the supply line to a reduced voltage level which is smaller than a minimum operation voltage level, the minimum operation voltage level being equal to or smaller than the normal operation voltage level and the drop of the supply power being caused by the ignition device switching into the turn-on state; in response to the determining, boosting the reduced voltage level to a boosted voltage level by a voltage upscaling device, the boosted voltage level reaching at least the minimum operation voltage level; operating, while the ignition device is in the turn-on state, the user terminal () with the power supply having the boosted voltage level; determining at least one of a turn-off state of the ignition device and termination of the drop of the supply power provided by the power supply () in the supply line; in response to the determining, terminating the boosting of the reduced voltage level; and applying the supply power to the user terminal () with the voltage level provided by the power supply (), the voltage level being the normal operation voltage level. Further, an agricultural machine is provided.
