following procedure can be used to verify preliminary operation.
1. Remove the instrument enclosure cover by turning counter clockwise to expose
the LS3200 Switch
electronics.
2. Turn on power at its source.
3. Observe that either the red or green LED comes on.
4. If neither lamp illuminates refer to the trouble shooting Section, 6.2.
5.2
L.E.D. and Relay Status Logic (Fail-Safe)
5.2.1
The 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.
5.2.2
Normal 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.)
