Example 4 : Differential Control
empty distance (P1-105 & P2-105), 11.0
feet
100%, span (P1-106 7P2-106), 10.0 feet
85% , Pt 1, high alarm on (P*213), 8.5 feet
80% , Pt 1, high alarm off (P*214), 8.0 feet
15% , Pt 2, low alarm off (P*254), 1.5 feet
10% , Pt 2, low alarm on (P*253), 1.0 feet
5%, Diff control, on, (P*223) 0.5 feet
1%, Diff. control, off, (P*224) 0.1 feet
Note
In this example, the transducers are mounted at the same height. If
the transducers are mounted at different heights, ensure that the
empty levels are correct such that there is no differential present
when the level is zero on both sides.
