• Mains off/mains on
If, during a communication interruption, operation is interrupted via Mains off/Mains on
at the (former) main pump, the (former) main pump starts with the last available spe-
cifications from the twin-head pump configuration.
This function is only available for twin-head pump operation. A particular pump can gener-
ally be enabled or disabled in terms of operation in menu <5.1.4.0>. A disabled pump can-
not be used in operation until the disabling has been manually lifted.
The setting can be made at each pump directly or over the infrared interface. If a pump
(main or partner pump) is disabled, it 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, pump kicks are carried out if activ-
ated. The interval for pump kicks starts when the pump is disabled.
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
