IEC61158 also supports the Fieldbus Intrinsically Safe
Concept (FISCO) model which allows more field devices in
a network. The FISCO model considers the capacitance and
inductance of the wiring to be distributed along its entire
length. Therefore, the stored energy during a fault will be
less and more devices are permitted on a pair of wires.
Instead of the conservative entity model, which only allows
about 90 mA of current, the FISCO model allows a maxi-
mum of 110 mA for Class II C installations and 240 mA
for Class II B installations.
FISCO certifying agencies have limited the maximum
segment length to 1000 meters because the FISCO model
does not rely on standardized ignition curves.
The Enhanced Eclipse Model 705 is available with entity IS,
FISCO IS, FNICO non-incendive, or explosion proof
approvals.
2.0 QuickStart Installation
The QuickStart Installation procedures provide the key
steps for mounting, wiring, and configuring the Eclipse
level transmitter. These procedures are intended for experi-
enced installers of electronic level measurement instruments.
See Complete Installation, Section 3.0, for detailed installa-
tion instructions.
WARNING: The Model 7xD, 7xR or 7xT overfill probes should be
used for Safety Shutdown/Overfill applications. All
other Guided Wave Radar probes should be installed
so the maximum overfill level is a minimum of
6" (150 mm) below the process connection. This may
include utilizing a nozzle or spool piece to raise the
probe. Consult factory to ensure proper installation.
2.1 Getting Started
Before beginning the QuickStart Installation procedures,
have the proper equipment, tools, and information available.
2.1.1 Equipment and Tools
• Open-end wrenches or adjustable wrench to fit the process
connection size and type. Coaxial probe 1¹â„2" (38 mm),
twin rod probe 1⁷⁄8" (47 mm), transmitter
1¹â„2" (38 mm). A torque wrench is highly desirable.
• Flat-blade screwdriver
• Cable cutter and ³â„32" (2.5 mm) hex wrench
(Flexible probes only)
• Fieldbus-compatible power supply with proper termination
