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.
