Introduction
Step One
About this Manual:
PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS
PRODUCT. This manual includes information on the NEO-7 series Ultrasonic Level Transmitter from
KOBOLD INSTRUMENTS. 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:
KOBOLD INSTRUMENTS 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.
Never
over tighten the sensor within the fitting. Always check for leaks prior to system start-up.
Wiring and Electrical:
A supply voltage of 14 to 28 VDC is used to power the NEO-7. 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 Polypropylene (PP) with the general purpose versions
and is made of aluminum for the intrinsically safe versions. 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 sensor housing is liquid-resistant the NEO-7 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.
Warning - Potential Electrostatic Charging Hazard (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.
Make a Fail-Safe System:
Design a fail-safe system that accommodates the possibility of switch and/or
power failure. KOBOLD INSTRUMENTS recommends the use of redundant backup systems and alarms in
addition to the primary system.
Flammable, Explosive or Hazardous Applications:
NEO-7006 & NEO-7012 series should not be used within classified hazardous environments. Only
the NEO-7006-IS and NEO-7012-IS are
rated for use in hazardous locations. Refer to the certificate of
compliance for all applicable intrinsically safe ratings and entity parameters. Refer to the National
Electric Code (NEC) for all applicable installation requirements in hazardous locations.
Warning:
Make sure that all electrical wiring of the switch is in accordance with applicable codes.
Warning:
Use only specified replacement parts or Intrinsic Safety can be impaired.
Warning:
To prevent ignition of explosive atmospheres, disconnect power before servicing.
