User's Responsibility for Safety:
KOBOLD manufactures a wide range of
process sensors and technologies. While each of these technologies are
designed to operate in a wide variety of applications, it is the user's
responsibility to select a technology that is appropriate for the application,
to install it per these installation instructions, to perform tests of the
installed system, and to 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 overtighten fittings. Always check for leaks prior to
system startup.
•
Wiring and Electrical:
A supply voltage of: 10-28 VDC is used to power
the ZDM. The sensor systems should never exceed this rating. Electrical
wiring of the sensor should be performed in accordance with all applicable
national, state, and local codes.
•
Temperature and Pressure:
The ZDM is designed for use in media
temperatures from -40 to 248°F, and for use at pressures up to 6500 PSIG,
depending on model. Operation outside these limitations will cause
damage to the unit and possible personal injury.
•
Material Compatibility:
Check your model number with the wetted
materials specifications of this manual. Make sure that the model which
you have selected is chemically compatible with the application liquids.
While the electronics housing is liquid resistant when installed properly, it is
not designed to be immersed. It should be mounted in such a way that it
does not normally come into contact with fluid.
•
Flammable, Explosive and Hazardous Applications:
The ZDM with
option Ex or EXA are intrinsically safe and are the only units which are to
be used in hazardous locations. Other ZDM models should not be used in
areas where an explosion proof design is required.
•
Make a Fail-Safe System:
Design a fail-safe system that accommodates
the possibility of switch or power failure as well as operator error. In critical
applications, KOBOLD recommends the use of redundant backup systems
and alarms in addition to the primary system.
