PROGRAM-1 . Switch ON and OFF a lamp using a single momentary push button.

PROGRAM-2 . Switch ON a motor with a Start momentary push button and switch OFF with a Stop momentary push button.

PROGRAM-3 . Switch ON all three motors with a single Start momentary push button and switch OFF all motors with a single Stop momentary push button.

PROGRAM-4 .ON/OFF of a lamp.

Inputs: Start Momentary P.B. and Stop Momentary P.B.

Outputs: Lamp.

When start PB is pressed, Lamp should ON and then when stop PB is pressed, Lamp should get off. (Make logic using Binary Bit as holding).

PROGRAM-5 . ON/OFF of a lamp using 3 Push Buttons. (No holding to be used).

Inputs: I/P-1, I/P-2, I/P-3.

Outputs: Lamp.

If any two input Push buttons are pressed simultaneously, then only the lamp should glow; otherwise, not.

PROGRAM-6 Combinations of switches to ON/OFF a lamp. (No holding required)

Inputs: PB1, PB2

Outputs:

O/P1: Green lamp

O/P2: Blue lamp

O/P3: Red lamp

1. ON/OFF of lamps. Inputs:–

I/P1– Start PB1 for pump1,

I/P2– Stop PB2 for pump1,

I/P3– Start PB3 for pump2,

I/P4– Stop PB4 for pump2.

Outputs:–

O/p1:– Green lamp,

O/p2:– Red lamp,

O/p3:– pump1,

O/p4:– pump2.

a) When I/P1 is pressed:– Pump1 starts and Red lamp glows. Then

b) When I/P3 is pressed:– Pump2 starts, Green lamp is ON and Red lamp gets off. Then

c) When I/P2 is pressed:– Pump1 switches off, Red lamp glows with Green lamp off. Then

d) When I/P4 is pressed:– Pump2 switches off and Red lamp also goes off. (as green lamp was previously off in step 3)

PROGRAM-7

Inputs:–

I/P1– Start PB1 for pump1, I/P2– Stop PB2 for pump1,

I/P3– Start PB3 for pump2, I/P4– Stop PB4 for pump2.

Outputs:–

O/p1:– Green lamp, O/p2:– Red lamp,

O/p3:– pump1, O/p4:– pump2.

a) When I/P1 is pressed:– Pump1 starts and Red lamp glows. Then

b) When I/P3 is pressed:– Pump2 starts, Green lamp is ON and Red lamp gets off. Then

c) When I/P2 is pressed:– Pump1 switches off, Red lamp glows with Green lamp off. Then

d) When I/P4 is pressed:– Pump2 switches off and Red lamp also goes off. (as green lamp was previously off in step 3)

Practice Program-02

An oil pump should start up after pressing start push button and the main motor will start automatically after 15 sec. After pressing stop push button main motor will stop immediately and the oil pump will stop automatically after 15 sec.

  3. When start toggle switch is pressed, a lamp goes ON for 10 Seconds. After 10 seconds lamp gets off while              toggle switch is still on.

1. A lamp goes ON after 20 seconds of pressing the start momentary push button and goes off by pressing the stop momentary push button.

1. There are two lamps. When start momentary push button is pressed, first lamp goes ON for 10 seconds, after 10 seconds first lamp goes off and second lamp goes ON. Pressing Stop momentary push button makes second lamp go off.
