Abstract

Method involves electrical control of actuator during load phase in such a manner that stroke produced by actuator opens drain valve mechanically. The time-dependent measurement of actuator tension and actuator charge is done during load phase. Timing progress of actuator capacity is calculated from measured actuator tension and measured actuator charge and maximum assigned time point of actuator capacity is determined as stop time point of valve body.
