mA mode
Current from an external device (BNC input) drives the pump that doses proportionally according to
the minimum and maximum set (0-20 mA or 4-20 mA).
To set press SCROLL until mA led turn on (red for 0-20 mA; green for 4-20 mA) and confirm with P
key.
To choose if...
... there is a mA current signal (controllers provided with proportional
output in current), and you have to dose a certain amount of product.
STROKE LENGHT ADJUSTMENT KNOB (0-100%) acts percentually on pump capacity.
STROKE FREQUENCY ADJUSTMENT (yellow labelled scale 0-100%) acts on injection per minutes.
CONSTANT mode
Pump doses at a constant rate set with stroke length adjustment knob.
To set press SCROLL until CONSTANT led turn on and confirm with P key.
To choose if...
... there is not an external signal, and you have to dose a certain amount
of product regularly.
STROKE LENGHT ADJUSTMENT KNOB (0-100%) acts percentually on pump capacity.
STROKE FREQUENCY ADJUSTMENT (yellow labelled scale 0-100%) acts on injection per minutes.
CONSTANT with
divider mode
Pump doses at a constant rate set with stroke length adjustment knob but this rate is divided by a
factor up to 10.
To set press SCROLL until CONSTANT and DIV 1÷10 led turn on together, then confirm with P key.
To choose if...
... there is not an external signal, and you have to dose a certain amount
of product regularly but pump capacity is too high
STROKE LENGHT ADJUSTMENT KNOB (0-100%) acts percentually on pump capacity.
DIVIDER FACTOR ADJUSTMENT KNOB (grey labelled scale 1-10%) set the divider factor 1-10 to
reduce pump capacity.
