Pump standstill

The wave packet method (standard) allows for variations in the volume flow by a factor of

10 in 30 increments. If the flow rate is too low, flap valves may cause a system standstill. In
addition, low power stages at low speeds may cause the rotors to stop. Such a standstill may
sometimes be desired, which is why stage 0 is allowed as the lowest stage.

The best speed limit is found in a simple test. Use the command “

u”

to set a speed for

testing. When setting the parameter “

u

”, the pump runs with the desired speed for system

control. Remove the rotor lid to see the rotor. Then lower the speed until the rotor stops. Set
the limit three increments above this point to ensure safe pumping.

Stability problems

The speed control has a PID controller. It ensures an exact and fast adjustment of the ac-

tual value to the set point.

In applications such as solar power systems or feed pumps,

the following parameters should be left in factory settings.

With a few exceptions, the

system will run stably. These two values have to be balanced, however, especially for hy-
gienic hot water from the external heat exchanger. In addition, in this case the use of an ultra-
fast sensor (non-standard accessory) is recommended at the hot water outlet.

The parameters

Pr

,

In

, and

di

can also be determined in a test: Assume that the pump is

running in automatic mode in a unit that is ready for operation with appropriate temperatures.
With

In

and

di

set to zero (= switched off),

Pr

is reduced every 30 seconds starting at 9 until

the system is instable. In other words, the pump speed changes rhythmically and can be read
in the menu “

n

” (=actual speed). The proportional part that becomes instable is noted as P

krit

just as the duration of the oscillation (= time between the two highest speeds) is noted as t

krit

.

The following formulas can be used to determine the correct parameters.

A typical result of hygienic service water with the ultrafast sensor is

Pr

= 8,

In

= 9,

di

= 3.

For reasons not entirely understood, the setting

Pr

= 3,

In

= 1,

di

= 4 has proven practical.

Probably, the control unit is so unstable that it oscillates very quickly and appears to be bal-
anced due to the system’s and the fluid’s inertia.
