The following settings are required in the "
Setup
>
Dosing timer week
" menu for each dosing procedure:
Fig. 29 Setting the timer
The batch volume (e.g. 80.5 ml) is set in the "
Setup
>
Dosing timer week
" menu. The dosing time required
for this (e.g. 39.0) is displayed and can be changed.
In the "
Operation
" menu, the total batch volume
(e.g. 80.5 ml) and the remaining batch volume to be
dosed is displayed. During breaks in dosing, the time
(e.g. 43:32) until the next dosing is displayed.

Analog output
Fig. 31 Configure analog output
The analog output of the pump is parametrised in the
"
Setup
>
Analog output
" menu. The following
settings are possible:
* Output signal is based on motor speed and pump
status (target flow).
** Signal has same analog scaling as the current
analog input signal. See 6.4.3 Analog 0/4-20 mA .
