Press the SEL button until the corresponding LED comes on.
After receiving an external pulse (water-meter pulse sender) and, with the potentiometer regulated to 100%, the
pump makes a stroke. By the potentiometer it's possible to reduce the maximum dosage percentage.
Press the SEL button until the corresponding LED comes on.
After receiving 4 external pulses (water-meter pulse sender) and, with the potentiometer regulated to 100%, the
pump makes a stroke. By the potentiometer it's possible to reduce the maximum dosage percentage.
Press the SEL button until the corresponding LED comes on.
After receiving 10 external pulses (water-meter pulse sender) and, with the potentiometer regulated to 100%, the
pump makes a stroke. By the potentiometer it's possible to reduce the maximum dosage percentage.
Press the SEL button until the corresponding LED comes on.
For every external pulse received (water-meter pulse sender), the pump makes "n" strokes, as red regulation scale
of the potentiometer (1-10). At the first signal received, the pump makes "n" strokes at maximum speed, and then
automatically distributes the "n" strokes, measuring the time between two successive pulses, for a maximum of 60
seconds, after which period the pump once again doses at maximum speed, resetting the time count. The pump
also has a memory alarm, which is triggered if it receives other external signals (water-meter pulse sender) during
the dosage of the "n" strokes
Press the SEL button until the corresponding LED comes on.
The pump proportionally doses at a signal comprised between 4 and 20 mA. At a signal of 4 mA, the pump comes
to a stop, at 20mA the pump doses at the percentage selected with the potentiometer.
Press the SEL button until the corresponding LED comes on.
The pump doses manually at the percentage selected with the potentiometer.
Dip Switch
Dip-switch 1) enables/disables key lock: in the ON position it enables the key lock; in this mode, pressing the SEL
button does not make it possible to change the pump operating mode. Pushing the SEL button will pause the
pump, while releasing it will enable the pump to begin dosing again. In the OFF position (default), the SEL button
operates normally.
Dip-switch 2) enables/disables pump lock for alarm: in the ON position, the fixed red LED comes on but the pump
continues to dose in the event of a level or flow rate alarm; in the OFF position (default), the fixed red LED comes
on and the pump stops in the event of a level or flow rate alarm.
Dip-switch 3) alarm relay mode: in the ON position, the alarm relay is normally closed and opens when the alarm
signal is triggered; in the OFF position (default), the alarm relay is normally open and closes when the alarm signal
is triggered.
Dip-switch 4) enables/disables the pacing mode: in the ON position it enables the pacing function, meaning that the
pump makes a strike with every external signal (thrust impulse counter), excluding potentiometer regulation; in the
OFF position, the pump doses as programmed, on the basis of the potentiometer regulation. This can only be
activated in modes 1:1, 4:1, 10:1 and 1xn. LEDs 1:1 and 1xN light up when the pacing mode is active
Dip-switch 5) enables/disables the flow sensor: in the ON position, the pump is enabled to receive flow rate sensor
signals. After 6 strikes of the pump without receiving signals from the sensor, the pump goes into alarm mode. In
the OFF position (default), the connection to the flow rate sensor is deactivated.
