And control the main contacts KM0 1 of the catalyst KM0 of machine drive motor M1 action.
Control circuit use 24V DC source power, including control switch Q1, turn-sensitive device S2, self-locking switch S1,
Display lamp H1, flashing indicator light H2, time relay TK0 and auxiliary reclay KA0, controlling switch Q1 is main circuit breaker Q0's
Auxiliary normally opened contact, described turn-sensitive device S2 is for sensing the duty of the drive mechanism of plant equipment.
Controlling switch Q1 and self-locking switch S1 to be sequentially connected in series, the outfan of self-locking switch S1 was connected to by the time
The extension break contact TK0 1 and catalyst KM0 of relay TK0 coils connected in series composition the first branch road, by turn-sensitive device
S2 and auxiliary reclay KA0 coil tandem composition the second branch road, by auxiliary reclay KA0 normally-closed contact KA0 1 and time
Between relay TK0 coil tandem composition the 3rd branch road, by the normally opened contact KM0 1 of catalyst KM0 and run indicator H1
The 4th branch road that composes in series, by the normally-closed contact KA0 2 of auxiliary reclay KA0, the normally-closed contact KM0 2 of catalyst KM0
