done via the operator wheel.
Pump is dosing the set volume (ml/contact). Setting is
done via the operator wheel.
Setting range 0.0013
– 12.8 ml/contact
The frequency of the incoming contacts is multiplied by
the set dosing volume. The pump is operated in constant
operation with maximum stroke frequency if the value
exceeds the maximum pump capacity. Excessive
contacts are ignored as long as the memory function is
not active.
Pump is dosing dependent on external analogue signal.
The dosing volume is proportional to the signal input
value in mA.
Setting is done via the operator wheel.
