Use the and arrow keys to enter the % of the
required value you want to increase or decrease
when the second sensor input is below Level 1. The
chart on the previous page uses -10% as an example. This represents an application where the sec-
ond sensor is in a well or tank. When the pressure reading or the second sensor drops below an
acceptable minimum, the discharge pressure set point automatically drops by 10% to give the tank
or well time to recover. As soon as the pressure in the well reaches the minimum again, the set
point returns to normal.
Press the key to advance to:
Use the and arrow keys to enter the % of
required value you want to increase or decrease
when the second sensor input is above level 2. The
chart on the previous page was -20% as an example. This represents an application where the sec-
ond sensor is a flow transducer in the discharge line. When the flow reading on this second sensor
goes higher than an acceptable maximum, the discharge pressure set point automatically drops by
20% until flow demand is reduced. As soon as flow is back below the maximum again, the set point
returns to normal.
