Safety Precautions; About This Manual - Omega LVU800 Series User Manual

SAFETY PRECAUTIONS
About this Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS PRODUCT. This
manual includes information on the LVU800 Series Ultrasonic Level Switch from OMEGA ENGINEERING. Please
refer to the part number located on the switch label to verify the exact model configuration, which you have
purchased.
User's Responsibility for Safety: OMEGA ENGINEERING manufactures a broad range of level sensing
technologies. While each of these sensors is designed to operate in a wide variety of applications, it is the
user's responsibility to select a sensor model that is appropriate for the application, install it 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: Only professional staff should install and/or repair this product. Install the
switch with the included FKM gasket and never over tighten the switch within the fitting. Always check for
leaks prior to system start‐up.
Wiring and Electrical: A supply voltage of 12 to 28 VDC is used to power the LVU800 Series. Electrical wiring
of the transmitter should be performed in accordance with all applicable national, state, and local codes.
Material Compatibility: The enclosure is made of Polycarbonate (PC). The transducer is made of
Polyvinylidene Fluoride (PVDF). Make sure that the model, which you have selected, is chemically compatible
with the application media.
Enclosure: While the switch housing is liquid‐resistant the LVU800 Series is not designed to be operational
when immersed. It should be mounted in such a way that the enclosure and transducer do not come into
contact with the application media under normal operational conditions.
The enclosure has a flip cover with dual 1/2" NPT female conduit ports and an internal terminal strip for
wiring. To open the enclosure, you will need a small insertion tool such as a screwdriver. Loosen the locking
screw located at the top front of the enclosure. Rotate the hinged cover up for 135° access to the faceplate
and terminal strips. Before closing the enclosure, make sure that the enclosure gasket is properly seated, and
that any conduit fittings, cable connectors or plugs are installed correctly and sealed.
Handling Static‐Sensitive Circuits/Devices: When handling the transmitter, the technician should follow these
guidelines to reduce any possible electrostatic charge build‐up on the technician's body and the electronic
part.
1. Always touch a known good ground source before handling the part. This should be repeated while
handling the part and more frequently after sitting down from a standing position, sliding across the
seat or walking a distance.
2. Avoid touching electrical terminals of the part unless making connections.
3. DO NOT open the unit cover until it is time to calibrate.
