5.3 External Input Signal Connections
The pump will accept any one of three different types of external input
signals; 4-20 mA , 0-10 VDC, or frequency. The 4-20mA and 0-10 VDC
loops must be powered. Two types of frequency inputs, AC sine waves
(magnetic coils type outputs) and Digital Square waves (Hall Effect signals,
contact closures), are acceptable. A jumper plug located on the circuit board
is factory pre-set for AC sine wave signals, the jumper must be re-
positioned when digital square wave signals are being used. See page 7,
“Hz input jumper settings”
All wiring connections are to be made inside of the junction box located on
the side of the pump. A liquid-tite connector is supplied and should be used
for the external signal cable. The signal input wires are color coded to the
type of signal being used.
