Lake Monitors Flow Transmitters - Manual (Page 32)

4-20 mA Output Connections
Wiring Instructions (Refer to Illustrations 2 and 3 above):
1) Move the programmable jumper on the signal conditioning
board into the position closest to the meter’s outlet, as shown
in Illustration 3.
2) Connect the positive DC power source (+12 to +35 VDC) to
terminal #1 on the din connector
3) Connect terminal #2 of the din connecter to the positive current
input on the receiving device.
4) If the power source does not originate from the receiving device,
the negative side of the power supply must be connected to the
signal ground of the receiving device.
5) If the transmitter is operating properly, the green LED on the
signal conditioning board will illuminate dimly at zero flow and
will increase in intensity as flow increases.
