RNLXX1 - IntelliPoint RF Series User's Manual
2.2
Mounting and Installation Guidelines (continued)
After the system is installed and the level is below the sensing
element, apply power. The RF series instrument wil
automatically calibrate and is ready to detect change in level.
If properly installed, the Green LED will illuminate when
power is applied. The two Red LEDs should not be flashing.
If either of the Red LEDs are flashing, refer to Section 4:
Troubleshooting.
The Sensing Element / Circuit Board side of the
IntelliPoint RF instrument is rated Intrinsically
Safe (I.S.)
WARNING:
The IntelliPoint RF equipment is rated explosion-proof/
flame-proof. When installing in explosion-hazardous areas
[rated "potentially hazardous" (EU) or "hazardous classified"
(USA)] observe all national and local regulations as well as
specifications in the certificate.
Mount sensing element using the following installation
guidelines. Refer to Figure 2-2.
• When installing the IntelliPoint RF instrument, ambient
temperature at the electronics must not exceed 70°C (158°F).
• When installing flange-mounted sensing elements, keep
mating surfaces and bolts free of paint and corrosion to
ensure proper electrical contact with vessel. Avoid using
excessive amounts of Teflon™ tape when installing threaded
sensing elements.
• Install systems with threaded NPT connection via wrench
flats on the process connection ONLY.
• Locate sensing element to avoid enhancing electrostatic
discharge from process medium, as is good practice with
any thermowell, displacer, or sampler. This includes correct
bonding to the tank or silo wall.
• If the installation area is rated explosion-proof and requires
conduit seal fittings, they should be used in accordance with
company standards and local codes.
• Do not mount a Cote-Shield sensing element through a
nozzle that exceeds the length of the first insulator.
• Ensure that there are no obstructions or agitator blades to
interfere with sensing element.
• Rigid sensing elements can be mounted either vertically or
horizontally.
