Caution
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.
