NOTICE
If a pump head is disabled and the operating mode "Parallel op-
eration" is activated:
In this case, it cannot be ensured that the desired duty point can be
reached with only one pump head.
NOTICE
If the pump is at a standstill for prolonged periods, the impeller
may seize up in the pump housing.
The pump kick reduces this risk. This is intended to ensure pump opera-
tion after a long standstill. If the "pump kick" function is deactivated,
smooth starting of the pump can no longer be guaranteed.
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.
The reason for the standstill is irrelevant. The pump kick is repeated until the pump is
switched back on via a control mechanism.
For double pump function ("Main/standby operation" mode), this also applies to the
standby pump. If the time interval before pump cycling set in menu <5.8.1.2> expires, a
pump kick takes place at the standby pump.
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 time 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.
NOTICE
If the "Operation" function has been chosen for EBM/SBM, each pump
kick produces a signal. The signal is visible for a few seconds each time.
NOTICE
In the event of a malfunction too, the system will also attempt to per-
form a pump kick.
The time remaining until the next pump kick can be seen on the display in menu <4.2.4.0>.
This menu is only available when the motor is stopped. The number of pump kicks is shown
in menu <4.2.6.0>. With the exception of warnings, all faults detected during a pump kick
will cause the motor to be switched off. The corresponding error code is shown on the dis-
play.
The pumps are equipped with an electronic overload protection function which switches
off the pump in the event of an overload.
The electronic modules are equipped with a non-fading memory for data storage purposes.
The data is retained no matter how long the module is disconnected from the power sup-
ply. When the voltage supply is re-established, the pump continues to run with the default
values prior to disconnection from the power supply.
The switching frequency can be changed via menu <4.1.2.0>, the CAN bus or the IR-Stick.
