electronics.

2.Turn on power at its source.

3.Observe that either the red or green LED comes on.

5.2L.E.D. and Relay Status Logic (Fail-Safe)

5.2.1The L.E.D.s (Red and Green) are an indication of the sensors status (ie. dry or wet) and are not affected by the position of the fail-safe jumper J-2. The fail-safe jumper J- 2 changes the relay activation status allowing the user to select the fail-safe power off condition most appropriate to the application. Refer to the tables below that show the logic conditions between the sensors, L.E.D. lights, relay coil and contacts for each position of the fail-safe jumper J-2.

5.2.2Normal Operation (as set at factory)

The switch comes configured from the factory with the following operation with the J-2 jumper in the B (2-3) position. (Refer to Figure 8.0.)
