J4 – Signal Connector
Pin 3 24V 60mA open collector Output failure. When a fault
condition is detected, the pump is stopped and this output is ON.
Pin 6 24V 60mA open collector Output When the output
frequency is less than 1117 Hz, this output is ON.
Pin 7 Analog output. A voltage from 0 to 10 Vdc proportional to
the output pump supplied current (from 0 to 2.5 A).
Pin 8 Analog output. A voltage from 0 to 10 Vdc proportional to
the output pump motor driving frequency (from 0 to 1167 Hz).
