This app is totally FREE with no ads and no pop-ups!

Start up is initialy in normal mode. This allows the user to experience:
- How a reversing starter works
- How to use the virtual voltmeter probes to measure voltages at
various test points (small black squares) in the control circuit
- Analyze the PLC logic, when the starter is in various control modes
(Run, Off and Auto)
The HMI only has control in Auto. The selector switches work as indicated by control circuit.
