22.03 VALUE INCREASE - As shown in previous figure, the
actual process setting will decrease by the VALUE DECREASE
with each additional pump that is added. To compensate for
this the VALUE INCREASE parameter increases the setpoint for
each pump that is added.
Required Setpoint = Original Setpoint - VALUE DE
VALUE INCREASE
Example - If the original setpoint was 200 PSIG and the
VALUE DECREASE was 5%, a second pump would be
activated at 190 PSIG. A VALUE INCREASE of 5% would result
in both pumps continuing to maintain constant pressure of
200 PSIG.
The VALUE INCREASE can be set higher than the VALUE
DECREASE to compensate for added frictional losses that
occur with increased flow.
