CONDITIONS FOR PLC OUTPUTS
1. FOR THE RUN LIGHT TO BE ENERGIZED, THE FOLLOWING CONDITION MUST BE MET………
a) stop
button must remain closed, and the start button must have been initiated, once
the run light is up, it has to stay up lashed.
2. FOR THE
CONVEYOR MOTOR TO RUN THE FOLLOWING CONDITION MUST BE MET…………
a) the run
light has to be energized
b)
either the Fill light must be de-energized or the Full light must be energized
3. FOR
THE FILL LIGHT TO BE ENERGIZED ONLY IF THE FOLLOWING CONDITION IS MET…….
a) the
proximity sensor must be closed
4. THE
FILL VALVE WILL OPEN AND START FILLING THE BOX ONLY IF THE FOLLOWING CONDITIONS
ARE MET………
a) the
fill light must be energized and the Full light NOT energized
5. THE
FULL LIGHT CAN ONLY BE ENERGIZED IF THE FOLLOWING CONDITIONS ARE MET………
a) the proximity
switch is closed and…….the level switch has been closed ( remember, the latch
will keep the light energized till the box leaves the Proximity switch)
This course is design to give delegates the basic knowledge needed to understand the Programmable Logic Controller. Upon completion of this 1 day event, each delegate should be able to:
1.
Understand the basic concept and development of PLC, its definition and
terminologies
2. Identify
the components in a PLC system, including hardware and software
3. Understand
the advantages of PLC over relay logic
4. Identify
basic PLC input and output systems
5. Identify
and list basic PLC programing languages
6. To
write simple ladder logic programs using timers, counters, latch output and
other functions.
7. know how to download programs and set the PLC
online.
8. Carry out practical exercise with a simulation
software.
