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 Junction Box: AU_5-
434_, AZ_8-434_ and AV_6-343_. The units are identical except for the number of switch points and the
sensors technology.
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 in application temperatures up to 80° C
(176° F). It is not designed for pressurized applications due to the wiring that must travel through a gasket
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:
Smart Trak™ may be used within flammable or
explosive applications only if the associated components are rated intrinsically safe for such use. In
hazardous applications, use redundant measurement and control points, each having a different sensing
technology.
Make a Fail-Safe System:
Design a fail-safe system that accommodates the possibility of transmitter or
power failure. In critical applications, Flowline recommends the use of redundant backup systems and
alarms in addition to the primary system.
