LOOP
1.
Connect the rain gauge to the INPUT terminal block. Polarity is not important as long as the rain
gauge switch is dry contact.
2.
Connect the user equipment to the LOOP terminal block. Apply positive power supply voltage
to the "+" terminal as shown in the diagram above. Connect the 4-20 mA output "-" terminal to
your monitoring equipment.
3.
Visually confirm that the MODE SELECT SWITCH is at the desired setting. Position 0 (RAMP
MODE) is the default setting for incrementing the output as rain accumulates. All other
positions place the unit in RAIN DETECT MODE, with the timeouts shown in the chart.
NOTE:
there is a pushbutton switch on the circuit board, below the selector switch. The pushbutton
has no function.
