Risk of dosing errors!
If repetition time t
2
is not long enough to dose
the batch quantity at the set dosing flow within
this time, the pump continues dosing until the
current batch quantity is finished. The pump is
then stopped and the next batch dosing is
triggered after the next repetition time.
Batch dosing in timer mode may be insufficiently
or excessively triggered in the event of an error if
the pump/system is not monitored. The system
must be protected redundantly.
