5.14 Batch
The pump is dosing the set quantity in batches at the
maximum capacity or the set maximum capacity, see
section
The quantity is dosed every time the pump receives
an external pulse.
If the pump receives new pulses before the previous
batch is performed, these pulses will be ignored.

The setting range is the same as for Timer, see

5.15 Anti-cavitation
The pump features an anti-cavitation function. When
this function is selected, the pump extends its
suction stroke, resulting in optimized priming.
The anti-cavitation function is used:
•
when pumping liquids of high viscosity
•
in the case of a long suction tube
•
in the case of a high suction lift.
Depending on the circumstances, the motor speed
during the suction stroke can be reduced by 75 %,
50 % or 25 % compared to the normal motor speed
during the suction stroke.
The maximum pump capacity is reduced when the
anti-cavitation function is selected. See section
