Operation
" menu
Analog scaling can also be modified after a security
prompt directly in the "
Operation
" menu. This is how
the dosing flow is directly modified for the current
flow input value.

Batch (pulse-based)
In this operation mode, the pump doses the
set batch volume in the set dosing time (t
1
).
A batch is dosed with each incoming pulse.
Fig. 22
Batch (pulse-based)
The setting range depends on the pump type:
*
Thanks to the digital motor control, dosing
quantities with a resolution of up to 1/8 of the
dosing stroke volume can be dosed.
The batch volume (e.g. 75 ml) is set in the "
Setup
>
Batch volume
" menu. The minimum dosing time
required for this (e.g. 36 seconds) is displayed and
can be increased.
Fig. 23
Batch
mode
Signals received during a batch process or an
interruption (e.g. alarm,
External stop
) will be
ignored. If the pump is restarted following an
interruption, the next batch volume is dosed on the
next incoming pulse.
Fig. 24
Batch
mode
In the "
Operation
" menu, the total batch volume (e.g.
75 ml) and the remaining batch volume still to be
dosed (e.g. 43 ml) are shown in the display.
