is fed to the microcontroller of the control section.
The control section. Fig 2 shows the circuit diagram of the control section for the phase-angle control of SCR. It comprises a microcontroller AT89C51, opto-coupler MCT2E, LED module and a few discrete components. Port 0 (P0.0 though P0.7) of AT89C51 is used for interfacing data input pins D0 through D7 of the LCD module. Port pins P2.6, P2.5 and P2.7 of the microcontroller control the registers select (RS), read/write (R/W) and enable (E) input pin of the LED module, respectively. Preset VR1 is used for controlling the contrast of the LC..................[:=> Show Contents <=:]

errupt INT1 is generated which starts the entire operation. Pressing switch S1 again disables external interrupt 0 and the message ‘SCR off’ is displayed. The complete SCR operation gets shut off.
On pressing S2, the delay increases by 1 ms (firing angle will shift by 18º) and firing of SCR is delayed by 1 ms. The power delivered to the load is also decreased by 10 per cent. The maximum delay that can be applied is 9 ms which will delay firing by an angle of 162º.When the limit is reached, it is indicated by LED3 and a message ‘Max. phase angle’ is displayed on the LCD. The glowing..................[:=> Show Contents <=:]
