TPE, TPED, NBE, NKE
Series 2000
The pumps have a factory setting of gain, K
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. This means that if the setpoint is increased,
the speed is reduced. In the case of inverse control,
the gain must be set within the range from -0.1 to
-20.
