Fig. 3: Constant speed
The speed of the pump can be kept to a constant speed between n
min
and n
max
. “Con-
stant speed” mode deactivates all other control modes.
PID control
If other sensors are used or if the distance between the sensors and the pump is very
large, the standard control modes are not applicable. In these cases, the “PID-Control”
function (
P roportional I ntegral D ifferential control) is available.
By selecting a good combination of individual control elements, the operator can ensure
fast-reacting, constant control without lasting setpoint deviations. The output signal of
the selected sensor can accept any intermediate value. The relevant actual value
reached (sensor signal) will be shown as a percentage on the status page of the menu
(100 % = maximum measurement range of the sensor).
NOTICE
The displayed percent value only corresponds indirectly to the current
delivery head of the pump(s).
The maximum delivery head can even been reached at a sensor signal of < 100 %.

NOTICE
The properties described in this section are only available if the internal MP interface
(MP = Multi Pump) is used.
