HC150 / HC101
Solenoid driven dosing pump
3.3 HC150 / HC101 PI
The pump can operate in constant mode as well as proportional mode to pulses sent from a counter.
In constant mode it operates like model HC150 / HC101 costant whereas in proportional pulse mode the pump
provides an injection for each "N" of pulses that the pump receives on the BNC – red connector, or N injections for
each pulse.
It is not designed to memorise the input pulses in case the frequency exceeds the maximum frequency of pump
operation.
The "N" parameter can be set between 1 and 1000 in division, or between 1 and 10 in moltiplication, in fact it is
possible to select 11 interval scales and then using the regulating knob select the desired value.
The selectable scale intervals are:
When setting the "N" parameter remember that in division when the knob is at its maximum it
corresponds to the lowest N value of the selected interval.
3.3.1 Interval scale change procedure
The following procedure allows you to switch from one interval scale to the other.
To perform this operation it is advisable to use a medium flat-tip screwdriver.
Turn the regulating knob to the minimum 0% (fully rotated counter clockwise):
The number of flashes of the LED (orange in division, green in moltiplication) indicates the scale that is
currently in use:
This is a circular menu, therefore if it exceeds the desired interval, it is not possible to go back, but
you must repeat the procedure three times until you reach the required interval again.
Turn the regulating knob to the maximum position (fully rotated clockwise) immediately followed by (within
two seconds) bringing the timer back to the minimum position.
The number of flashes of the LED (orange in division, green in moltiplication) indicates the selected interval
scale:
