00:06Welcome, in this video we will practice the direct start of one or more
00:10Motors and automation using timers, this in CAD SIMU, for the control of a motor by
00:16Initial impulse and automatic stop after a certain time. To implement the circuit.
00:21For control we will need a contactor, a thermal relay, a timer, and pushbuttons
00:26Normally open and closed, and a running light. For the motor power circuit
00:34We begin with the phase and protection lines, followed by the protection fuses,
00:39a normally open triple contactor, followed by a thermal relay and the three-phase motor.
00:47We made the connection and the connection of the three-phase motor protection, we changed
00:52the names of the elements, such as the triple contactor, which will be called C1, and the thermal relay
00:57It will be F1.
01:04For the control circuit, we first have the phase line,
01:16followed by a normally closed thermal contact, followed by another normally closed push button
01:27closed, followed by a normally closed timer contact on disconnection.
01:42Following another normally closed push button, the interlocking will be performed
01:49of the normally open contact, and that by means of the timer to the connection, or also known
02:03Since it is on delay, it will count from the last number to the first number; the operating cycle is,
02:08Pressing C1 closes the power supply circuit of the C1 coil, self-supporting by 13 and 14.
02:15The timer's normally closed contact remains closed and will only open after the programmed time.
02:20from the moment the C1 coil was energized, automatically disconnecting the entire system.
02:27The stop button has been installed so that the system can be de-energized at any time.
02:33The thermal relay should operate normally.
02:40We make the connection, the thermal relay contact will be F1, the normally closed push button will be S0,
02:47We changed the names of the elements, and the thermal relay will be F1, the timer contact to the
02:53The normally closed disconnect contact will be S1, the normally open contact will be C1,
02:58The timer C1 will also be named that way, and the running light will be called H.
03:11We move on to the simulation; it appears to be working correctly, and the timer is on.
03:15It works with a 10-second countdown; after this, the system stops.
03:25That's all, if you found it useful don't forget to subscribe.
