Pump kick

This function is only available with dual pump operation. If a pump
head (master or slave) is disabled, the pump head is no longer ready
for operation. In this state, errors are identified, displayed and
reported. If an error occurs in the enabled pump, the disabled pump
does not start up.
However, the pump kick is still performed if it is activated. The interval
to the pump kick starts with the disabling of the pump.
NOTE:
If a pump head is disabled and operating mode "Parallel operation" is
activated, it cannot be ensured that the desired duty point will be
achieved with just one pump head.
A pump kick takes place after a configurable time has elapsed since a
pump or pump head stopped operating. The interval can be set man-
ually in menu <5.8.1.2> on the pump for a period of between 2 h and
72 h, in 1 h steps.
Factory setting: 24 h.
NOTE:
If the menu <5.8.x.x> cannot be selected, no configurations can be
made. The factory settings values apply.
The reason for the standstill is not important (Manual off, External off,
Fault, Adjustment, Emergency operation, BMS setting). This proce-
dure is repeated until the pump is switched back on via a control
mechanism.
The "pump kick" function can be disabled via menu <5.8.1.1>. As
soon as the pump is switched on via the control system, the count-
down to the next pump kick is interrupted.
A pump kick lasts 5 seconds, during which the motor turns at the set
speed. The speed can be set between the minimum and maximum
permissible pump speeds in menu <5.8.1.3>.
Factory setting: minimum speed
If both pump heads on a double pump are switched off, for example,
via External off, both will run for 5 seconds. Pump kick takes place
even in "main/standby operation" mode if pump cycling takes longer
than the configured time via the <5.8.1.2> menu.
NOTE:
A pump kick is also attempted even in case of a fault.
The remaining operating time until the next pump kick can be read off in
menu <4.2.4.0>. This menu is only available when the motor is stopped.
The number of pump kicks can be read off in menu <4.2.6.0>.
All faults, with the exception of warnings, that occur during the pump
kick switch the motor off. The corresponding error code is shown on
the display.
NOTE:
The pump kick reduces the risk of an impeller jamming in the pump
housing. This is intended to ensure pump operation after a long
standstill. If the pump kick function is deactivated, secure starting of
the pump can no longer be guaranteed.
The pumps are equipped with an electronic overload protection func-
tion which switches off the pump in the event of an overload.
For data storage, the electronic modules are equipped with a perma-
nent memory. The data is retained no matter how longer the module
is disconnected from the power supply. When the power supply is re-
established, the pump continues to run with the values set prior to
disconnection from the power supply.
