Pump kick
Overload protection
86
This function is only available with twin-head 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 a fault occurs in the enabled pump, the disabled pump
does not start up.
However, the pump kick is still executed when it is activated. The
interval to the pump kick starts with the disabling of the pump.
NOTICE:
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
manually 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.
NOTICE:
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, Extern 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 countdown 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 twin-head pump are switched off, for exam-
ple, via Extern 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.
NOTICE:
A pump kick is also attempted even in the event of a fault.
The remaining operating time until the next pump kick can be read off
the display 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.
NOTICE:
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, safe 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 long the module is
disconnected from the power supply. When the voltage supply is
re-established, the pump continues to run with the values set prior to
disconnection from the power supply.
