12. Programming Examples
When following these examples, you will need to refer to the Program Reference section to see which
options are available for each of the parameters (P1, P24, etc.).
12.1 Setting Stage OnPoints and OffPoints
OnPoint and OffPoint are easily set by pressing the numbered button on the left hand side of
the front panel. When you press one of the stage buttons, the main display will show “ON”.
Then use the + and - buttons until you see your setting in the individual stage display. (The
