Motor starting - Star-Delta with timer

This video shows how to convert easily control/wiring ckt in to plc ladder diagram and also shows how to control three motors sequentially on siemens logo.

Step 1 The main contactor depends upon the normally open input start push button (I3), normally closed stop button (I2) and normally closed overload relay (I1). It means that Main contactor will only be energized if start button is pressed, while stop is not pressed and overload relay is not activated. A normally open input named (Q1) is added in parallel to the start button I3. Step 2 Star con...

General electrical/electronics theory equations. This equation is used to as a guide line for TVET students and other persons.

Most applications use more than and equal two motors for operation. But the major thing is they need not to be activated at a time, Motors need to start after some interval. i.e., sequential control after some delay. So, this sequential control comes in for action. We use an ON delay timer in this sequential control. The timer makes control automatically without any manual help. This saves Manu...

Automatic water-level controller are used to automatically fill the process tank when water in the tank below /above the minimum / maximum level and as well as monitor the water level in it. The water level is sensed by floats to operate the switches for controlling the pump motor. Automatic water level controllers switch the motor on whenever the water level drops below a certain level and shu...

In this video we show how to measure and check electrical equipment’s using digital millimeter and construct on printing circuit board (PCB). This video is prepared to boost your technical ability with practical training. The main Advantages of this video for electrical and computer engineering 1. To got different electrical license and start your business, 2. To take electrical/electronics coc...
