3. Control system program
You are also to prepare a control system program for the units’ PLC. The program should account for the following tasks:
• Emergency stop.
• Solar power vs battery life vs pump runtime.
• Pump runtime vs tank water level.
Present your final program in the form of a screenshot from the PIC logicator program, with a written explanation identifying the key points of your program.
Extension - an optional extra of a water clarity alarm or a dry run alarm would be advantageous.
