2.0 Complete Installation
This section provides detailed procedures for properly
installing, wiring, configuring, and, as needed, troubleshooting the PULSAR Model R86 Radar Level Transmitter.
2.1 Unpacking
Unpack the instrument carefully. Make sure all components
have been removed from the packing material. Check all
contents against the packing slip and report any discrepancies
to the factory.
Before proceeding with the installation, do the following:
• Inspect all components for damage. Report any damage to
the carrier within 24 hours.
• Make sure the nameplate model number on the antenna and
transmitter agree with the packing slip and purchase order.
• To avoid moisture ingress in the housing, covers should be
fully tightened at all times. For the same reason, plugs
should remain properly installed in the cable entries until
replaced with a cable gland
• Record the model and serial numbers for future reference
when ordering parts.
2.2 Electrostatic Discharge (ESD)
Handling Procedure
MAGNETROL 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
12
WARNING! Potential electrostatic charging hazard. Do not rub
with dry cloth.
58-603 Pulsar®Model R86 Radar Transmitter
2.3 Before You Begin
2.3.1 Site Preparation
Each PULSAR Model R86 Radar transmitter/antenna is
built to match the physical specifications of the required
installation. Ensure that the antenna process connection is
correct for the threaded or flanged mounting on the vessel
where the transmitter will be placed. See Mounting,
Section 2.4.
Ensure that all local, state, and federal regulations and
guidelines are observed. See Wiring, Section 2.5.
Ensure that the wiring between the power supply and
PULSAR Model R86 Radar transmitter is complete and
correct for the type of installation. See Specifications,
Section 3.7.
2.3.2 Equipment and Tools
No special tools are required. The following items are
recommended:
• Threaded antenna and process connection. . . . 2" (50 mm)

2.3.3 Operational Considerations
Radar applications are characterized by three basic conditions;
• Dielectric (process medium)
• Distance (measuring range)
• Disturbances (turbulence, foam, false targets, multiple
reflections and rate of change).
The PULSAR Model R86 Radar transmitter is offered with
a horn antenna configuration—Horn (1½", 2", 3", 4").
Ideally, if the installation allows, the 4" (DN100) horn
antenna should be used to ensure the best possible performance in all operational conditions.

2.3.3.2 Minimum Distance
If the liquid level is allowed onto the antenna, noise and
media build-up drastically decrease reliable measurement.
Liquid should not be allowed closer than two inches
(50 mm) from the bottom of the antenna or 12 inches
(300 mm) from the sensor reference point, whichever is
greater.

2.3.3.3 Problematic Applications; GWR Alternative
Some applications can be problematic for Non- Contact
Radar. For these, Guided Wave Radar is recommended:
ε
• Extremely low dielectric media (
<1.7)
r
• Stillwells, standpipes, bridles, cages and bypass columns.
• Very weak reflections from the liquid surface (particularly
during turbulence) can cause poor performance.
• Tanks heavily cluttered with false targets (mixers, pumps,
ladders, pipes, etc.)
• During times of very low liquid levels of low dielectric media,
the metal tank bottom may be detected which can deteriorate performance.
• Foam can either absorb or reflect the microwave energy
depending upon the depth, dielectric, density and wall
thickness of the bubbles. Due to typical variations in the
amount (depth) of foam, it is impossible to quantify performance. It may be possible to receive most, some or none
of the transmitted energy.
• When measurement close to flange is critical
Extremely high liquid levels (Overflow) conditions when
liquid very near the antenna can cause erroneous readings and measurement failure.

.50" (13 mm)
Minimum
2" (50 mm)
"
L " Dimension (Nozzle Height)
Almost any object that falls within the beam pattern will
cause reflections that may be misinterpreted as a false liquid
level. Although PULSAR Model R86 has a powerful Echo
Rejection routine, all possible precautions should be taken
to minimize false target reflections with proper installation
and orientation. Refer to section 2.4.2.3 for additional
information.
2.4.1.4 Nozzles
Improper installation in a nozzle can create “ringing” that
will adversely affect measurement. The antenna should
always be mounted so the active section of the antenna is a
minimum of 0.5" (12mm) outside the nozzle. Antenna
extensions are offered to allow the PULSAR Model R86
transmitter to work reliably in nozzles up to 72" (1.8
meter). See Section 3.7.6 for dimensional drawings of all
antenna designs including nozzle extensions.
Be sure to include any nozzle distance extending within
the vessel.
PULSAR Model R86 Mounted in
Stillwell (Bridle)
2.4.1.5 Standpipes and Stillwells
The PULSAR Model R86 can be mounted in a standpipe
or stillwell but certain items must be considered:
1
• Metal stillwells only: Sizes 1
⁄2–4 inches (38–100 mm).
• Diameter must be consistent throughout length; no reducers
or gaps.
• Stillwell length must cover complete range of
measurement (i.e., liquid must be in stillwell).
• Welds should be smooth.
• Vents: holes <0.125" (3 mm) diameter,
slots <0.125" (3 mm) width.
• If an isolation valve is used, it must be a full port
ball valve with an I.D. equal to the pipe diameter.
• Configuration must include a non-zero entry for
PIPE I.D parameter.
2.4.2 Installing the Transmitter
• Remove the protective plastic cap from the top of antenna.
Store the cap in a safe place in case the transmitter has to be
removed later.
16
• Carefully place the transmitter on the antenna.
• Rotate the transmitter to face the most convenient direction
for wiring, configuration and viewing.
• Do not place insulating material around any part of the
radar transmitter including the antenna flange.

2.4.2.1 Low Echo Margin
Echo Margin is a parameter that, when used with Echo
Strength, can be a very useful troubleshooting tool. It is
defined as a numeric value that is related to the strength of
the target peak relative to the Level Threshold or competing
waveform features, i.e., noise.

⁄2 radius
Echo Loss: If the Level signal is lost repeatedly at a specific
point in the vessel, it is usually a symptom of multipath
(side-wall) reflections causing cancellation by returning to
the transmitter exactly 180° out of phase with the actual
Level signal. This can be improved by applying the following procedure:
• Scroll to Display Config Menu under Device Setup. Scroll
down to Echo Strength and Echo Margin and change the
settings from Hide to View. This will allow you to view
these values from the home screen.
• Bring the Level up (or down) to the exact point where the
signal is repeatedly lost. Monitor the Echo Margin value as
this point is being approached. The Echo Margin value will
degrade to a low point before it begins to increase.
• Refer to Section 4.4 for additional information.

2.5 Wiring
Caution: HART versions of the PULSAR Model R86 transmitter
operate at voltages of 11–36 VDC. FOUNDATION fieldbus
versions operate at 9–17.5 VDC. Higher voltages will damage the transmitter.
Wiring connections between the power supply and the
PULSAR Model R86 Radar Transmitter should be made
using 18–22 AWG (0.5
–1mm2) shielded twisted pair
instrument cable. Connections are made to the terminal
strip and the ground connections within the top enclosure
compartment.
The instructions for wiring the PULSAR Model R86
transmitter depend on the application:
• General Purpose or Non-Incendive (Cl I, Div. 2)
• Intrinsically Safe
• Explosion Proof
WARNING! Explosion hazard. Do not disconnect equipment unless
power has been switched off or the area is known to be
non-hazardous.
To avoid moisture ingress in the housing, covers should be
fully tightened at all times. For the same reason, cable
gland and plugs should be properly installed in the cable
entries.
™
2.5.1 General Purpose or Non-incendive (Cl I, Div. 2)
A general purpose installation does not have flammable
media present.
Areas rated Non-Incendive (Cl I, Div. 2) have flammable
media present only under abnormal conditions.
No special electrical connections are required.
Caution: If flammable media is contained in the vessel, the trans-
mitter must be installed per Class I, Div 1 standards of
area classification.
To install General Purpose or Non-Incendive wiring:
1. Remove the cover from the wiring compartment of the
transmitter. Install the conduit plug in the unused opening
and use PTFE tape/sealant to ensure a liquid-tight
connection.
2. Install a conduit fitting and pull the supply wires.
3. Connect shield to an earth ground at power supply.
4. Connect an earth ground wire to the nearest green ground
screw (not shown in illustration).
5. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.
18
6. Replace and tighten the cover to the transmitter wiring
compartment before applying power.

An Intrinsically Safe (IS) installation potentially has flammable media present. An approved IS barrier must be
installed in the non-hazardous (safe) area to limit the available energy out to the hazardous area.
See Agency Drawing – Intrinsically Safe Installation,
Section 3.5.1.
To install Intrinsically Safe wiring:
1. Ensure that the IS barrier is properly installed in the safe
area (refer to local plant or facility procedures). Complete
the wiring from the power supply to the barrier and from
the barrier to the PULSAR Model R86 transmitter.
2. Remove the cover from the wiring compartment of the
transmitter. Install the conduit plug in the unused opening
and use PTFE tape/sealant to ensure a liquid-tight
connection.
3. Install a conduit fitting and pull the supply wires.
4. Connect shield to an earth ground at power supply.
5. Connect an earth ground wire to the nearest green ground
screw (not shown in illustration).
6. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.
7. Replace and tighten the cover to the wiring compartment
of the transmitter before applying power.
2.5.3 Explosion Proof
Explosion Proof (also referred to as XP or flameproof ) is
another method of designing equipment for installation
into hazardous areas. A hazardous location is an area in
which flammable gases or vapors are (or may be) present
in the air in quantities sufficient to produce explosive or
ignitable mixtures.
The wiring for the transmitter must be contained in
Explosion Proof conduit extending into the safe area.
• Due to the specialized design of the PULSAR Model R86
transmitter, no Explosion Proof conduit fitting (EY seal) is
required within 18" of the transmitter.
58-603 Pulsar®Model R86 Radar Transmitter
• An Explosion Proof conduit fitting (EY seal) is required
between the hazardous and safe areas. See Agency
Specifications, Section 3.5.

2.6 Configuring the Transmitter
Although the PULSAR Model R86 transmitter can be
delivered pre-configured from the factory, it can also be
easily reconfigured in the shop or at the installation using
the local LCD/Keypad or PACTware/DTM. Bench config-
uration provides a convenient and efficient way to set up
the transmitter before going to the tank site to complete
the installation.

Before configuring any transmitter, collect all operating
parameters information (refer to Section 1.1.2).
Apply power to the transmitter and follow the step-by-step
procedures for the menu-driven transmitter display. Refer
to Sections 2.6.2 and 2.6.4.
Information on configuring the transmitter using a HART
communicator is given in Section 2.7, Configuration
Using HART.
Refer to I/O manual 58-641 for information on
OUNDATION fieldbus output.

2.6.1 Bench Configuration
The PULSAR Model R86 transmitter can be easily configured at a test bench by connecting a standard 24 VDC
power supply directly to the transmitter terminals as
shown in the accompanying diagram. An optional digital
multimeter is shown in the event that mA current measurements are desired.
NOTE: Current measurements taken at these test points are an
approximate value. Accurate current readings should be
taken with the digital multimeter directly in series with the
loop.

2.6.2 Menu Traversal and Data Entry
The four push buttons offer various forms of functionality
for navigation and data entry.
The PULSAR Model R86 user interface is hierarchical in
nature, best described as a tree structure. Each level in the
tree contains one or more items. Items are either menu
labels or parameter names.
• Menu labels are presented in all capital letters
• Parameters are capital words
2.6.2.1 Navigating the Menu
UP moves to the previous item in the menu branch.

Height, 4 mA setpoint and 20 mA setpoint.
Push button Keystroke Action
Moves up to the next highest digit (0,1,2,3,....,9
Up
or decimal point). If held down the digits scroll
until the push button is released.
Moves up to the next lowest digit (0,1,2,3,....,9 or
Down
Back
Enter
decimal point). If held down the digits scroll until
the push button is released.
Moves the cursor to the left and deletes a digit. If
the cursor is already at the leftmost position,
then the screen is exited without changing the
previously saved value.
Moves the cursor to the right. If the cursor is
located at a blank character position, the new
value is saved.
All numeric values are left-justified, and new values are
entered from left to right. A decimal point can be
entered after the first digit is entered, such that .9 is
entered as 0.9.
Some configuration parameters can have a negative
value. In this case, the leftmost position is reversed for
the sign (either "-" for a negative value, or "+" for a positive value).
2.6.2.4 Entering Numeric Data Using Increment/Decrement
Use this method to input the following data into
parameters such as Damping and Failure Alarm.
Push button Keystroke Action
Increments the displayed value. If held down
the digits scroll until the push button is released.
Up
Depending on which screen is being revised, the
increment amount may increase by a factor of 10
after the value has been incremented 10 times.
Decrements the displayed value. If held down the
digits scroll until the push button is released.
Down
Depending on which screen is being revised, the
decrement amount may increase by a factor of
10 after the value has been decremented 10
times.

2.6.2.5 Entering Character Data
This method is used for parameters requiring alphanumeric
character entry, such as for entering tags, etc.
General Menu Notes:
Push button Keystroke Action
Moves to the previous character (Z...Y...X...W).
Up
If held down, the characters scroll until the push
button is released.
Moves to the next item character (A...B...C...D).
Down
Back
Enter
If held down, the characters scroll until the push
button is released.
Moves the cursor back to the left. If the cursor is
already at the leftmost position, then the screen
is exited without changing the original tag characters.
Moves the cursor forward to the right. If the
cursor is at the rightmost position, then the
new tag is saved.
2.6.3 Password Protection
The PULSAR Model R86 transmitter has three levels of
password protection to restrict access to certain portions of
the menu structure that affect the operation of the system.
User Password
The User Password allows the customer to limit access to
the basic configuration parameters.
The default User Password installed in the transmitter at
the factory is 0. With a password of 0, the transmitter is no
longer password protected and any value in the basic user
menus can be adjusted without entering a confirming
password.
The user password can be changed to any numerical value
up to 59999. When the transmitter is programmed for
password protection, a password is required whenever
configuration values are changed.
NOTE: If a User Password is not known or has been misplaced, the
menu item New Password in the DEVICE SETUP/ADVANCED
CONFIG menu displays an encrypted value representing the
present password. Contact Technical Support with this
encrypted password to retrieve the original User Password.

Advanced Password
Certain portions of the menu structure that contain more
advanced parameters are further protected by an Advanced
Password.
This password will be provided, when necessary, by Factory
technical support.
Factory Password
Calibration-related and other factory settings are further
protected by a Factory Password.
2.6.4 Model R86 Menu: Step-By-Step Procedure
NOTE: Context-sensitive HELP is available for all menu and parameter
items. With the item highlighted, hold down the ➪ENTER key
for two seconds. Use UP and DOWN for navigation.

The tables in Section 2.6.5 provide a complete explanation
of the software menus displayed by the PULSAR Model
R86 transmitter. The menu layout is similar between the
local Keypad/LCD interface, the DD, and the DTM.
Use these tables as a step-by-step guide to configure the
transmitter based on the desired measurement type from the
following selections:
Up Down Back Enter
• Level Only
• Volume & Level
• Flow
HOME SCREEN
The Home Screen consists of a “slide show” sequence of
Measured Values screens which are rotated at 2-second
intervals. Each Home Measured Value screen can present up
to four information items:
®
• HART
Tag
• Measured Value
Label, Numerical Value, Units
• Status
Will be displayed as text or optionally with NAMUR
NE 107 symbol
• Primary Value Bar Graph (shown in %)
The Home Screen presentation can be customized by viewing or hiding some of these items. See DISPLAY CONFIG
under the DEVICE SETUP menu in Section 2.6.5 —
Configuration Menu.
