This section provides detailed procedures for properly installing,
wiring, configuring and, if needed, troubleshooting the Jupiter
magnetostrictive level transmitter.
In most cases, externally mounted units will be shipped from
the factory attached to the Orion Instruments magnetic level
indicator.
1.1
Installation Prep
1.1.1 Factory Mounting & Pre-configuration
All Jupiter Model JM4 transmitters sold with Orion Instruments
magnetic level indicators (MLIs) are shipped pre-mounted and
pre-configured. The span for 4-20 mA and HART or Founda-
tion FIELDBUS is set to the span of the process connections on
the MLI. For instructions on how to re-configure the transmit-
ter, see Section 1.5 Configuration.
1.1.2 Unpacking
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
accounted for and inspected.
1.1.3 Electrostatic Discharge Handling
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 com-
ponent 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 compo-
nents or connector pins.
• Make sure that all electrical connections are completely made
and none are partial or floating. Ground all equipment to a reli-
able earth ground.
1.1.4 Site Preparation (Power Supply)
Each Jupiter magnetostrictive transmitter is built to match the
specifications required within the defined model 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.
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 1.4
.
1.1.5 Equipment and Tools
To attach a Jupiter transmitter to an existing MLI or direct inser-
tion 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.
• Tape measure or ruler if configuring via Set 4 mA and Set 20 mA
display screens.
• Digital multimeter or DVM to troubleshoot supply voltage
problems.
• 2.5 mm Allen key to tighten transmitter to probe connection.
1.1.6 Mounting Transmitter Head
To attach the JM4 transmitter head to the probe, place the
female transmitter connection (Figure 1-2) over the male probe
connection (Figure 1-3), and rotate until the pins slide into
place. Use a 2.5 mm Allen key to hand tighten set screw (Fig-
ure 1-1) to secure the transmitter head in place. Once secured,
rotate display until its in the desired position. If transmitter head
rotation is not desired, tighten the rotation screw, also with a 2.5
mm Allen key.
Caution:
In case of potential head space constraints, ensure that
an extra 1.5 inches is available in addition to the height
of the transmitter head (and flange, where applicable).
This extra space is required for attaching or removing the
transmitter head when necessary.
NOTE: For dimensions, see Section 2.5.4.
