active.
The dosing
quantity is
exceeded when
the input DI1 has
been deactivated.
→ Increase the values of the
parameters A and B in order
to reduce the activation time of
the digital input DI1 and so that
"A*T + B" < flow rate times T.
→ or set a time delay before
the valves open. See chap.
“9.7.24” and “9.7.25”.
→ or reduce the flow rate in the

The dosing
quantity, deter-
mined by the
device depending
on the activation
duration of the
digital input DI1,
has exceeded
the required
thresholds.
→ Set the values of the param-
eters A and B and the value
of the activation duration T so
that "A*T+B" < 100 000 and
"A*T+B" times the K factor
of the fitting used is higher or
equal to 6.
→ Set an activation duration
T < 300 s.
→ Confirm the message by
pressing the key "ENTER" or
by sending out a pulse on DI4:
the current dosing is aborted.
