Method for controlling at least one power generator, implementing a touch-sensitive screen on which there selectively appears a set of command buttons available at a given point in time, said method implementing the following steps: - determining a working context, as a function of at least a current working mode of the power generator and a level of authorization of a current user; - selecting a set of command buttons available for said working context, said set of command buttons comprising, for at least some working contexts, following buttons: - a selector enabling the selection of a mode of working of said power generator from among at least the following four modes: - a mode called a "not-in-service" mode; - a manual or « manu » working mode; - an automatic or "auto" working mode; - a "test" working mode; - an on/off switch, said switch being active only in the "manu" mode and proposing only the « On » possibility if said power generator is off and only the « Off » possibility if said power generator is on; - displaying said set of available command buttons on said touch-sensitive screen; - - detecting an activation of one of the available command buttons, called an activated command button; performing at least one action associated with said activated command button, as a function of said step for detecting an activation, characterized in that said step for detecting an activation of one said available command buttons comprises the following sub-steps for at least certain buttons and/or certain working contexts: - detecting a touch-sensitive contact on a zone of said touch-sensitive screen on which one of said command buttons is displayed; - if the touch-sensitive contact is shifted outside said zone by means of a sliding movement on the surface of the screen, no action associated with said button is performed; - if the touch-sensitive contact is released, a time-out is initiated for a predetermined duration, said predetermined duration varying as a function of said working context or said activated command button; - if a new touch-sensitive contact occurs before the end of said time-out, no action associated with said button is performed; - if no new touch-sensitive contact occurs before the end of said time-out, said action or actions associated with said button are performed. - determining a working context, as a function of at least a current working mode of the power generator and a level of authorization of a current user; - selecting a set of command buttons available for said working context, said set of command buttons comprising, for at least some working contexts, following buttons: - a selector enabling the selection of a mode of working of said power generator from among at least the following four modes: - a mode called a "not-in-service" mode; - a manual or « manu » working mode; - an automatic or "auto" working mode; - a "test" working mode; - an on/off switch, said switch being active only in the "manu" mode and proposing only the « On » possibility if said power generator is off and only the « Off » possibility if said power generator is on; - a selector enabling the selection of a mode of working of said power generator from among at least the following four modes: - a mode called a "not-in-service" mode; - a manual or « manu » working mode; - an automatic or "auto" working mode; - a "test" working mode; - a mode called a "not-in-service" mode; - a manual or « manu » working mode; - an automatic or "auto" working mode; - a "test" working mode; - an on/off switch, said switch being active only in the "manu" mode and proposing only the « On » possibility if said power generator is off and only the « Off » possibility if said power generator is on; - displaying said set of available command buttons on said touch-sensitive screen; - - detecting an activation of one of the available command buttons, called an activated command button; performing at least one action associated with said activated command button, as a function of said step for detecting an activation, - detecting a touch-sensitive contact on a zone of said touch-sensitive screen on which one of said command buttons is displayed; - if the touch-sensitive contact is shifted outside said zone by means of a sliding movement on the surface of the screen, no action associated with said button is performed; - if the touch-sensitive contact is released, a time-out is initiated for a predetermined duration, said predetermined duration varying as a function of said working context or said activated command button; - if a new touch-sensitive contact occurs before the end of said time-out, no action associated with said button is performed; - if no new touch-sensitive contact occurs before the end of said time-out, said action or actions associated with said button are performed.
