Method of operation
Actuation of pushbutton I simultaneously energizes star contactor Q13, timing relay K1 and, via normally open
contact Q13/13–14, step contactor K16, and are maintained via K1/13–14. When K1 has elapsed, normally closed contact K1/55–56
de-energizes star contactor Q13 and – via normally open contact Q13/13–14 – Q16 de-energizes: The
starting transformer is disconnected, and the motor runs at rated speed.
The motor cannot start up again unless previously switched off by actuation of pushbutton 0, or in the event of an
overload, by normally closed contact 95–96 of the overload relay F2. With two-wire control, overload relay F2
must always be set to manual reset. If the motor has been switched off by F2, the motor cannot start up
again unless the manual reset is released.
