The pumps have a factory setting of gain, K
p
and
integral time, T
i
.
However, if the factory setting is not the optimum
setting, you can change the gain and the integral
time:
• Set the gain within the range from 0.1 to 20.
• Set the integral time within the range from 0.1 to
3600 seconds.
If you select 3600 seconds, the controller
functions as a P controller.
Furthermore, you can set the controller to inverse
control.
