Operational Check
Before installing the switch a simple operational check should be performed, as follows:
1. Fill a container with water
2. Open the electronics housing cover and connect power (see section on “
Wiring
”).
3. Set the Fail Safe jumper to the LLFS position (lower two pins).
4. Apply power
5. Place the sensor gap into the water. The relay will energize (the contacts between (NC) and (C) should open).
6. Remove the sensor from the liquid. The relay will de-energize (the contacts between (NC) and (C) should close).
7. Disconnect the wiring.
Mounting
For threaded process connections, screw sensor into the opening using a wrench on the sensor mounting nut flats. Use
thread tape or suitable pipe compound on the threads. If flanged, bolt the sensor to the mating flange with the proper
gasket.
The sensor gap must protrude into the vessel / pipe being measured. The sensor will not function properly if the detection
tip is in a nozzle. See the following drawings for mounting guidelines:
