Most reversing controllers contain mechanical interlocks as well as electrical interlocks.

Forward reverse motor control with interlock.

If an oversight allows the second coil to remain energized without closing its contacts the excess current in the coil due to the lack of the proper. Click image to enlarge. Otherwise the plc program will never recognize the overload signal because the starter will be turned off in the circuit during the same scan.

Forward reverse mechanical interlock wiring tutorial tagalog basic motor control. Starter f is blocked by coil r in the same manner. Forward reversing starter with mechanical and electrical interlocking. To prevent unintentional energization of both the forward and reverse coil at the same time the coils are equipped with normally closed contacts which are then wired in series with the opposite direction s coil to act as an electrical interlock.
