4 - 20 mA Input
Used to remotely control the pump with an incoming 4-20 mA signal.
Default settings:
4 mA = 0% motor speed
20 mA = 100% motor speed
Press MODE button until
4 - 20 mA Input
is displayed in the top line of the
display.
To configure the pump, navigate to
4 - 20 mA Input
menu by using the short-cut
method described at the beginning of section, or by pressing MENU button, then
selecting Input Setup, Input Modes, and then
4 - 20 mA Input
Four points on the slope must be defined; 1) a low mA value, 2) an output rate at
the low mA value, 3) a high mA value, and 4) an output rate at the high mA
value.
To input mA values, press the RIGHT ARROW to select the digit to change,
press UP or DOWN arrow to scroll through 0 - 9 on selected digit. Press enter to
save changes and move to the next input screen.
To input flow rate values, press the RIGHT ARROW to select the user defined
flow rate unit of measure, motor RPM, or %Speed values. Press UP or DOWN
arrow to increase or decrease the value. Press and hold the arrow to increase or
decrease progressively faster. Press enter to save changes and move to the
next input screen.
Continue this process until all four screens have been configured.
If you used short-cut to enter 4-20 mA input setup, press and hold the Mode button until the Run Mode screen is
displayed.
If you used Menu button to navigate to 4-20 mA input setup, you must navigate back out of menu structure. To do
this you must select <-Esc at bottom of every screen menu until you see Run Mode screen displayed.
Note: The pump is designed to fail safe. If the input signal drops below 3.0 mA, the pump assumes a lost
signal and the motor speed is set to 0 RPM.
