Dosing timer cycle
In this operation mode, the pump doses the
set batch volume in regular cycles.
Dosing starts when the pump is started after a
singular start delay. The setting range for the batch
volume corresponds to the values in section
6.4.4 Batch (pulse-based) .

In the event of an interruption (e.g. interruption of the
mains voltage,
External stop
), the dosing will be
stopped while the time continues running.
After suspending the interruption, the pump will
continue to dose according to the actual timeline
position.
The following settings are required in the "
Setup
