1.1Description
F
OUNDATION fieldbus
™
is a digital communications system
that serially interconnects devices in the field. A Fieldbus
system is similar to a Distributed Control System (DCS)
with two exceptions:
• Although a F
OUNDATION fieldbus
™
system can use the same
physical wiring as an existing 4–20 mA device, Fieldbus
devices are not connected point to point, but rather are
multidropped and wired in parallel on a single pair of wires
(referred to as a segment).
OUNDATION fieldbus
•F
™
is a system that allows the user to
distribute control across a network. Fieldbus devices are
smart and actually maintain control over the system.
Typical Fieldbus Installation
Unlike 4–20 mA analog installations in which the two wires
carry a single variable (the varying 4–20 mA current), a digital communications scheme such as F
OUNDATION fieldbus
considers the two wires as a network. The network can carry
many process variables as well as other information. The
Enhanced Jupiter transmitter is a F
OUNDATION fieldbus
™
registered device that communicates with the H1
OUNDATION fieldbus
F
™
protocol operating at 31.25
kbits/sec. The H1 physical layer is an approved IEC 61158
standard.
An IEC61158 shielded twisted pair wire segment can be as
long as 6234 feet (1900 meters) without a repeater. Up to
4 repeaters per segment can be used to extend the distance.
The maximum number of devices allowed on a Fieldbus
segment is 32 although this depends on the current draw
of the devices on any given segment.

Details regarding cable specifications, grounding, termination,
and other network information can be found in IEC 61158
or the wiring installation application guide AG-140 at
www.fieldbus.org.
1.2Benefits
The benefits of F
OUNDATION fieldbus
™
can be found
throughout all phases of an installation:
1. Design/Installation: Connecting multiple devices to a single
pair of wires means less wire and fewer I/O equipment.
Initial Engineering costs are also reduced because the
Fieldbus Foundation requires interoperability, defined as
“the ability to operate multiple devices in the same system,
regardless of manufacturer, without a loss of functionality.”
OUNDATION fieldbus
All F
™
devices must be tested for
interoperability by the Fieldbus Foundation. Orion
Instruments Jupiter device registration can be found at
www.fieldbus.org. Choose Magnetrol as the device manufacturer when searching for the registration.
2. Operation: With control now taking place within the
devices in the field, better loop performance and control are
the result. A F
OUNDATION fieldbus
™
system allows for multiple variables to be brought back from each device to the
control room for additional trending and reporting.
3. Maintenance: The self-diagnostics residing in the smart
field devices minimizes the need to send maintenance
personnel to the field.
1.3Device Configuration
57-649 Jupiter Magnetostrictive Transmitter - FOUNDATION fieldbus™
Device Descriptions
The function of a F
OUNDATION fieldbus
™
device is determined by the arrangement of a system of blocks defined by
the Fieldbus Foundation. The types of blocks used in a typical User Application are described as follows:
Resource Block describes the characteristics of the
OUNDATION fieldbus
F
™
device such as the device name,
manufacturer, and serial number.
Function Blocks are built into the F
OUNDATION fieldbus
™
devices as needed to provide the desired control system
behavior. The input and output parameters of function
blocks can be linked over the Fieldbus. There can be
numerous function blocks in a single User Application.
Transducer Blocks contain information such as calibration
parameters and sensor type. They are used to connect the
sensor to the input function blocks.
5
An important requirement of Fieldbus devices is the interoperability concept mentioned earlier. Device Description
(DD) technology is used to achieve this interoperability.
The DD provides extended descriptions for each object and
provides pertinent information needed by the host system.
DDs are similar to the drivers that your personal computer
(PC) uses to operate peripheral devices connected to it. Any
Fieldbus host system can operate with a device if it has the
proper DD and Common File Format (CFF) for that device.
The most recent DD and CFF files can be found on the
OUNDATION fieldbus
F
1.4Intrinsic Safety
The H1 physical layer supports Intrinsic Safety (IS) applications with bus-powered devices. To accomplish this, an IS
barrier or galvanic isolator is placed between the power
supply in the safe area and the device in the hazardous area.
H1 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 maximum of 110 mA for Class II C installations and 240 mA
for Class II B installations.
™
web site at fieldbus.org.
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 Jupiter Magnetostrictive transmitter is available with entity IS, FISCO IS, FNICO non-incendive, or
explosion proof approvals.

C
facturer, protection provided by equipment may be
impaired
This section provides detailed procedures for properly
installing, wiring, configuring and, if needed, troubleshooting the Jupiter magnetostrictive level transmitter.
In most cases the unit will be shipped from the factory
attached to the Orion Instruments magnetic level indicator.
In some cases, such as retrofit applications of a reed chain
transmitter with a Jupiter instrument, the installation and
set up will need to be performed in the field.
2.1Unpacking
Unpack the instrument carefully. Inspect all units for
damage. Report any concealed damage to carrier within
24 hours. Check the contents against the packing slip and
purchase order. Check and record the serial number for
future reference when ordering parts.
Caution: Do not discard the shipping container until all parts are
Magnetrol/Orion’s electronic instruments are manufactured to the highest quality standards. These instruments
use electronic components that may be damaged by static
electricity present in most work environments.
The following steps are recommended to reduce the risk of
component failure due to electrostatic discharge.
• Ship and store circuit boards in anti-static bags. If an antistatic bag is not available, wrap the board in aluminum
foil. Do not place boards on foam packing materials.
• Use a grounding wrist strap when installing and removing
circuit boards. A grounded workstation is recommended.
• Handle circuit boards only by the edges. Do not touch
components or connector pins.
• Make sure that all electrical connections are completely
made and none are partial or floating. Ground all equipment to a good, earth ground.

2.3.1 Site Preparation
Each Jupiter magnetostrictive transmitter is built to match
the specifications required within the defined model
option number. Wiring terminations will need to be made
and the configuration will need to be accomplished.
Ensure that the power to be supplied to the instrument is
the same voltage (24 VDC) as ordered with the instrument, and that the wiring between the power supply and
the Jupiter transmitter is correct for the type of installation. See Specifications, Section 5.3.
NOTE: Applying incorrect voltage will damage the unit.
When installing the Jupiter transmitter in a general
purpose or hazardous area, all local, state, and federal
regulations and guidelines must be observed. See Wiring,Section 2.5.
2.3.2 Equipment and Tools
For installation of a new Jupiter with magnetic level indicator set, refer to Orion Instruments instruction manual
46-638.
To attach a Jupiter transmitter to an existing MLI or direct
insertion model, you may need the following tools:
5
⁄16" Nut-Driver (for tightening the mounting clamps).
•
• Screwdriver and assorted hand tools for making conduit
and electrical connections.
• Digital multimeter or DVM to troubleshoot supply
voltage problems.

2.3.3 Operational Considerations
Exterior ambient temperature of the service should not
exceed the design specifications of the electronics (-40° to
+175° F (-40° to +80° C)). The operating temperature
limits of the LCD are -5° to +160° F (-20° to +70° C).
Temperatures below -5° F will cause the display to temporarily white out, and temperatures above +160° F will
cause the display to go temporarily black. It will recover
without damage when the operating temperature range
returns. A sunshade should be used if electronics are
mounted in direct sunlight.
Maximum process temperature for direct insertion
transmitters is +500° F (+260° C). Externally mounted
transmitters can be used with process temperatures up
to +800° F (+427° C) if the MLI is equipped with an
insulation blanket from the factory.
2.3.4 Configuration Information
Some key information is needed to configure the Jupiter
transmitter. Complete the following operating parameters

where it will be attached. Mark the location and the exact
area where the clamps will be attached to hold the Jupiter
in place.
3. Attach the lower clamp and tighten so that it remains in
place, but loose enough so that there is still room to place
the guide tab from the Jupiter between the inside of the
clamp and the outer diameter of the MLI chamber. See
Figure 1.
4. The upper clamp will need to be open to a large enough
diameter to be able to mount to the MLI as well as the
probe. The upper clamp should be positioned just above
3
⁄4" NPT threads. See Figure 2.

7. Discard any tape temporarily holding the Jupiter to the
MLI.
2.4.2 Internal, Direct Insertion
Use caution when handling probes to ensure probe is not
bent during installation. A bend in the probe may prevent
float from traveling freely up and down the probe.
1. Verify float will pass through vessel opening, if not, it will
be necessary to attach the float after the probe is installed.
2. Carefully insert probe into vessel and thread or bolt to the
mating connection as appropriate.
3. The float is held on the probe by a C-clip inserted into a
groove machined into the tip of the probe. The float is
attached or removed by removing and reinserting the
C-clip. See Figure 3. To ensure proper float orientation,
the float is marked “Up ”.
