How To Change the Set Point Value
Follow these instructions to change the value of one of the internal set points, A through E.
Refer to
How To Adjust the Analog Set Point Value
, page 76, for information on changing the
analog set point value.
1. Issue the following command to set the value of the set point:
S
x value
ENTER
where
x
= 1 for set point A
2 for set point B
3 for set point C
4 for set point D
5 for set point E
value
= % of full scale pressure, if the unit is in pressure control
% of open, if the unit is in position control (direct direction)
% of close, if the unit is in position control (reverse direction)
The system responds by immediately storing the set point value. The system pressure
does not change however, unless the selected set point is the
active
set point.

R
