00:06In this video we're going to control two motors sequentially and automatically using a timer.
00:12CAT SIMU, for this we need a phase and protection power supply,
00:24then a circuit breaker,
00:34followed by a triple contactor and thermal relay and a three-phase motor,
00:55We connected and changed the names on both the triple contactor and the thermal relay.
01:02For the contactor it will be C1, for the thermal relay it will be F1, and for the second motor F2.
01:11We copied the design for the second motor; once the power circuit was finished, we moved on to the control circuit, which
01:18First, we will set the phase line,
01:25followed by a normally closed thermal contact, followed by another,
01:39then a normally closed push button,
01:45another normally open push button,
01:51which will be the interlock, for the normally open auxiliary contactor, in parallel with a normally open time-delay contact,
02:04The lower part consists of a timer and a lamp.
02:13and coil, subsequently, of three additional lamps,
02:26We move on to the connection,
02:32with actuators of two normally open thermal contacts,
02:48Next, we change the names; for the thermal contacts, they will be F1 and F2.
03:02Next, we changed the name of button S0,
03:05We then designate the normally open push button as S1,
03:11whose normally open auxiliary contactor will be C1,
03:18the following element also as C1,
03:21The running lights will be known as H1, H2, and the stopping lights are H3, H4.
03:29the timer will be C1,
03:41the coil as C4, the normally open contacts as F1 and F2,
04:03We move on to the simulation, the operating cycle; when S1 is pressed, the coil's power supply circuit is closed.
04:10C1 being energized,
04:11self-supporting, while the C4 coil remains de-energized,
04:16After the programmed time of 10 seconds has elapsed, the open timed contact closes.
04:22energizing the coil of C4, so that both motors are running,
04:26The C4 coil does not need auxiliary or holding power because the time-delay contact will remain closed until the C1 coil is de-energized.
04:35Pressing S0 will interrupt the entire system.
04:40The thermal relays should normally operate in the event of an overload in any of the motors and at any time.
04:51We can see that it's okay, well if you found the video helpful don't forget to subscribe.
