List of Experiments

1. DOL Starter with single phasing prevention
2. Changeover switch implementation with interlocking
3. Star Delta starter
   - single phasing prevention
   - Adjustable star-delta transfer time
   - Pre-settable Overload trip time
4. Automatic Load transfer
   - transfers load from one phase to another when one phase in a 3 ph. system fails
   - automatically restores when power is resumed
   - time delays are effected to prevent action during short time failure
5. Industrial sliding door automation
   - Sequencing
   - Open ¼ th Full width
   - Wait for next go command
   - Next open full
   - wait for a time and close full
6. Fire Alarm
   - Multiple alarms
   - sound alarm 1
   - if not acknowledged, sound alarms 1 and 2
   - similarly go upto 4 alarms
7. Conveyor Belt sorting
   - storing to left bin
   - storing to right bin
   - storing to exit bin
8. Three floor Hoist controller
   - Sequencing
   - floor level detection
   - Gate safety latch
9. Burglar scare random lighting in building with variable timing
   - The lights in each room are switched on at pre-determined intervals and switched off at pre-determined time. The lighting is shifted from area to area randomly to scare the burglars with a false fear of presence of people.
10.  Analog input to PLC as a set of value for a comparator function block
    - The output is multilevel illumination control. The input setting is by means of a potentiometer in an analog input to the PLC. The outputs turn on several groups of lamps to obtain desired level of illumination.
11. Heater control with PID function of the PLC
    - A 1000 W water heater is controlled using the PID function of the PLC. The temperature transducer is a Temperature transmitter with 4 to 20 mA output and Pt 100 Probe
12. Round Table - Liquid filling System Dropping of Reagents into test tubes. The feedback is from a potentiometer. The program must ensure that the end limits of the pot are never reached by carefully balancing the clockwise and anti-clockwise revolution.
13. Sequential timer for educational institute Timings are alterable by supervisor while program is running. Preand-post – Holiday sequence selectable
14. PC monitoring of PLC operation. RS232 or USB communication for status display of inputs and outputs.
15. Slow speed motor control using PWM function of the PLC
    - Slow speed 12V DC 18W Permanent Magnet Motor with a fly wheel is controlled with the PWM output and a feedback from a low resolution encoder
16. Man-machine interface lay-out and annunciation functions
17. Noise Immunity at the inputs of PLC
    - Measurement of input resistance of the PLC
    - Determine the effect of high o/p source resistance at the inputs
18. Testing of RC snubber component for protection of PLC output from a highly inductive components like solenoids or relays.
