Input Voltage/Current versus RPM
Note 1: Maximum current is reduced provided control method is set according to actual
input method (ie 0 – 5 VDC or 0 – 10 VDC). If desired control method is set for
“4–20mA” but a 0 – 5 VDC or 0 – 10 VDC is applied the maximum current will be
at its greatest.
Note 2: Absolute maximum input voltage is 10.8 VDC
Note 3: Absolute maximum current is 22 mA
When start/stop is controlled via the analog input the pump(s) will stop when the analog input
goes below the minimum voltage/current. The pumps will run when the minimum voltage/current
is reached and will run at the minimum speed.
