Introduction / Table of Contents Step One

The general purpose level switch package provides automatic tank filling and emptying up to 10’ (3m) between
two adjustable level switch points. The compact level controller with optional strobe alert provides one latching
16A relay for pump or valve control. Offered in three level sensor technologies, select the type based upon
your application media. This polypropylene liquid level switch package is widely selected for sump, process
and day tank level applications.

FEATURES

 Fail-Safe relay control of pumps, valves or alarms with a 0 to 60 second delay.
 Offered in three sensing technologies for broad application coverage: ultrasonic vibration & buoyancy.
 Polypropylene enclosure rated NEMA 4X with swivel base for conduit alignment.
 Easy setup with LED indicators for sensor(s), power and relay status.
 Invert switch changes relay state from NO to NC without rewiring.
 AC powered

Safety Precautions Step Three

About This Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS

PRODUCT. This manual includes information on the Smart Trak™ with Compact Relay Controller: AU23­43__, AV23-43__ & AZ23-43__. The units are identical except for the sensor technology and optional
Strobe Alert.

User’s Responsibility for Safety: Flowline manufactures a wide range of liquid level sensors, controllers

and mounting systems. It is the user’s responsibility to select components that are appropriate for the
application, install them properly, perform tests of the installed system, and maintain all components. The
failure to do so could result in property damage or serious injury.

Proper Installation and Handling: Use a proper sealant with all installations. Never over tighten the

components. Always check for leaks prior to system start-up.

Material Compatibility:

o Glass filled Polypropylene (PP, a polyolefin): Track, end cap, wire retainer clips, bayonet adapter,

level switch and sensor car for all Smart Trak Assemblies.

o Polychlorotrifluoroethylene (PCTFE, a fluoroplastic): Sensor car locking bolt and screw.
o Polypropylene (PP, a polyolefin): Sensor, top compression fitting, thrust plate, locking pin and 2" NPT

fitting.

o Viton (a fluorocarbon): O-ring.
o Neoprene (w/silicon gel for lubrication): Wire gasket.
o Santoprene (w/silicon gel for lubrication): Seal plug.

Make sure that the application liquids are compatible with the materials that will be wetted. To determine
the chemical compatibility between the components and its application liquids, refer to the Compass
Corrosion Guide, available from Compass Publications.

Temperature and Pressure: Smart Trak™ is designed for use i n a p plic a t ion t e m perature s up to 8 0° C ( 176°

F). It is not designed for pressurized applicat ions due to the wiring tha t must travel thr ough a ga sket at the head .

Wiring and Electrical: Electrical wiring of any liquid level control system should be performed in

accordance with all applicable national, state, and local codes. Take care not to cut or break the outer
insulation jacket of wiring that may be immersed while routing cables in the Smart Trak™ system. Such
breaks of the liquid seal of the sensor system may lead to component failure.

Flammable, Explosive and Hazardous Applications: The AU23-43__, AZ23-43__ and AV23-34__

Smart Trak™ should not be used within classified hazardous environments.

Safety Cover: Based upon the part number selected, a safety cover has been placed within the enclosure.

Always replace the safety cover after any service.
