1.2 QuickStart Mounting
NOTE: Confirm the configuration style and process connection (size
and type) of the PULS R radar transmitter. Make sure it matches
the requirements of the installation before continuing with the
QuickStart installation.
Confirm the model and serial numbers on the nameplates
of PULSAR electronics and antenna are identical.
1.2.1 Antenna
Carefully place the antenna into the vessel. Mount in a
location equal to 1⁄2the radius of tank top. Do not mount in
center of vessel nor closer than 18" (45 cm) of tank wall.
Secure the antenna to the vessel.
Leave the protective plastic cap in place until ready to
install the transmitter.
NOTE: Do not use sealing compound or TFE tape on antenna connec-
tion to transmitter. This connection is sealed by a Viton®O-ring.
1.2.2 Transmitter
1. Remove the protective plastic cap from the top of the
antenna and store for future use. Make sure the bottom of
the Universal connector (TFE) and inside of the antenna
are clean and dry. Clean with isopropyl alcohol and cotton
swabs if necessary.
2. Place the transmitter on the antenna.
3. Ensure the housing/launcher set screw is loose and the
housing can be turned. Align the antenna index mark so it
is at an angle of 45° to a line from the radar unit to the
nearest tank wall. Do not optimize the Quality (signal
strength) at one level in the vessel.
4. Rotate the transmitter so that it is in the most convenient
position for wiring, configuring, and viewing.
5. While keeping the housing and launcher aligned, tighten
both the housing/launcher set screw and large Universal
connector Hex nut. Tighten the universal connector to
30 ft./lbs of force. A torque wrench is highly desirable.
DO NOT LEAVE HAND TIGHT.
• Do not place insulating material around any part of the
Radar transmitter including the antenna flange.

2.0 Complete Installation
This section provides detailed procedures for properly
installing, configuring, and, as needed, troubleshooting the
PULSAR Radar Level Transmitter.
2.1 npacking
Unpack the instrument carefully. Make sure all components
have been removed from the packing material. Check all the
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.
• 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 anti-
static 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 equip-
ment to a good, earth ground.

10 58-601 Pulsar®Radar Transmitter
2.3 Before You Begin
2.3.1 Site Preparation
Each PULSAR Radar transmitter is built to match the specific
physical specifications of the required installation. Make sure
the antenna connection is correct for the threaded or flanged
mounting on the vessel or tank where the transmitter will
be placed. See Mounting, Section 2.4.
Make sure that the wiring between the power supply and
Radar transmitter are complete and correct for the type of
installation.
When installing the Radar 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
No special tools are needed. The following items are
recommended
• Threaded antenna and transmitter . . . . . . 2" (50 mm)
• Transmitter/antenna connection. . . . . . . . 13⁄4" (44 mm)
• Transmitter adjustment . . . . . . . . . . . . . . 11⁄8" (28 mm),
3⁄32" (2.5 mm) Hex
• Torque wrench . . . . . . . . . . . . . . . . . . . . . highly desirable
• Flat-blade screwdriver
• Digital multimeter or volt/ammeter . . . . . Optional
• 24 VDC (23 mA) power supply. . . . . . . . Optional
2.3.3 Operational Considerations
Radar applications are characterized by three basic conditions;
Dielectric, Distance (measuring range) and Disturbances
(turbulence, foam, false targets, multiple reflections and rate
of change). The PULSAR Radar transmitter is offered with
three antenna configurations—Dielectric Rod, 4" (DN100)
Horn and 6" (DN150) Horn. Ideally, the 6" (DN150)
Horn antenna should be used to ensure the best possible
performance in all operational conditions.

11
58-601 Pulsar®Radar Transmitter
2.3.3.1 The chart below shows the maximum measuring range
(Distance) of each antenna based on fundamental condi-
tions of Dielectric, Distance and Turbulence. Maximum
distance is calculated as Tank Height + Sensor Offset
(see page 20). It is measured from the Sensor Reference
Point (bottom of NPT thread, top of BSP thread or face
of a flange).
2.3.3.2 Minimum Distan e
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 2 inches (50 mm)
from the bottom of the antenna.
2.3.3.3 Problemati Appli ations; GWR Alternative
Some application concerns can be problematic for Radar.
For these, Guided Wave Radar is recommended
• Extremely low dielectric media (εr<2.0)
• 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 deteriorating per-
formance.
• 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 per-
formance. It may be possible to receive most, some or none
of the transmitted energy.
• Extremely high liquid levels (Overflow) conditions when
liquid very near the antenna can cause erroneous readings
and measurement failure.

2.4 Mounting
The PULSAR Radar transmitter can be mounted to a vessel
using a variety of process connections. Generally, either a
threaded or flanged connection is used.
2.4.1 nstalling the Antenna
Before installing, make sure
• Model and Serial numbers on the nameplates of the PULSAR
antenna and transmitter are identical.
• Process temperature, pressure, dielectric, turbulence and
distance are within the antenna specifications for the
installation.
• Rod of a Dielectric Rod antenna is protected from bending
or breaking; there is no metal sub-structure.
• Insulating material is not placed around any part of the
Radar transmitter including the antenna flange.
• Protective cap is kept on the antenna if the transmitter is to
be installed at a later time.
• Antenna is being mounted in the optimal location. See fol-
lowing sections Location, Beam Angle, Obstructions and
Nozzles for specific information.
• If the liquid level is allowed onto the antenna, noise and
media buildup drastically decrease reliable measurement.
Liquid should not be allowed closer than 2 inches (50 mm)
from the bottom of the antenna.
2.4.1.1 Lo ation
Ideally, the Radar transmitter should be mounted providing
an unobstructed signal path to the liquid surface where it
should illuminate (with microwave energy) the largest,
possible surface area. See Section 2.4.1.2, Beam Angle.
Unavoidable obstacles will produce reflections that must be
minimized during field configuration. See Section 2.6.5.1,
Target Rejection. Mount in a location equal to 1⁄2the radius
of tank top. Do not mount in center of vessel nor closer
than 18" (45 cm) of tank wall.
2.4.1.2 Beam Angle
The various antenna designs exhibit different beam patterns.
Ideally, the beam pattern should illuminate the maximum
liquid surface with a minimum striking other objects in the
vessel including the tank wall. Use these drawings to deter-
mine the optimum installation location.

58-601 Pulsar®Radar Transmitter
2.4.1.3 Obstru tions
Almost any object that falls within the beam pattern will cause
reflections that may be misinterpreted as a false liquid level.
Although PULSAR has a powerful False Target Rejection
routine, all possible precautions should be taken to minimize
false target reflections with proper installation and orientation.
2.4.1.4 Nozzles
Improper installation in a nozzle creates “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 transmitter to work reliably in
nozzles with “L” dimensions of 1" (25 mm), 4" (100mm),
8" (200mm) or 12" (300mm). Standard antennas (no
extension) are shown below for reference. See Section 3.6.5
for dimensional drawings of all antenna designs including
nozzle extensions.

2.4.1.5 Standpipes and Stillwells
PULSAR can be mounted in a standpipe or stillwell but
certain considerations should be given
• Metal stillwells only Sizes 3–8 inches (80–200 mm).
• Diameter must be consistent throughout length; no reducers.
• Use only horn antennas sized to pipe ID; 3–6"
(80–150mm); 8" pipe can use a 6" horn.
• Stillwell length must cover complete range of measurement
(i.e., liquid must be in stillwell).
• Welds should be smooth.
• Vents holes <0.5" diameter, slots <0.5" width.
• If an isolation valve is used, it must be a full port ball valve
with an I.D. equal to the pipe diameter.
• Bridles/Bypass Installations The launcher (index mark)
should be rotated 90° from process connections.
• Configuration must include an entry for PIPE I.D.
See Section 2.6.5.1, Item 35- PIPE I.D.
• There will be some increased dielectric sensitivity; system
GAIN will be reduced when PIPE ID >0.
2.4.2 nstalling the Transmitter
• Remove the protective plastic cap from the top of antenna.
• Carefully place the transmitter on the antenna.
• Rotate the transmitter to face the most convenient direction
for wiring, configuration and viewing. Do not tighten the
universal connector (large hex nut) nor the set screw on the
housing base. The transmitter launcher must be oriented
properly for optimal performance.
• Do not place insulating material around any part of the
radar transmitter including the antenna flange.
2.4.2.1 Orientation
The PULSAR transmitter utilizes a linearly polarized,
microwave beam that can be rotated to improve its perform-
ance. Proper orientation can minimize unwanted target
reflections, decrease sidewall reflections (multipath) and
maximize direct reflections from the liquid surface. The index
mark located on the side of the launcher is oriented in the
same direction as the polarization.
The index mark is also present for reference(1 dot GP/IS or
2 dots XP). The launcher is considered to be at 0° when
the index mark is closest to the tank wall.

2.4.2.2 Initial Installation
Ideally, the transmitter should be mounted half the radius
from the tank wall. Align the index mark so it is at an angle
of 45 degrees to a line from the radar unit to the nearest
tank wall. For horizontal cylindrical vessels, align the
launcher (index mark) so it is facing along the long axis of
the vessel. Do not optimize the Quality (signal strength) at
one level in the vessel. Once properly oriented, tighten set
screws and Universal connector (30 ft-lbs of force).
A transmitter mounted within 18" (45 cm) of a tank wall
may demand orientation adjustments to limit multipath
and optimize performance. See Section 2.4.2.3 Signal Loss.

Distance, Dielectric, Turbulence, Rate Change, Foam) or
when launcher is repositioned.
2.4.2.3 Poor Signal Quality
Poor signal quality has many potential causes. Following are
two initial areas for investigation.
Launcher Orientation: Initial launcher orientation is always
45 degrees (see Sections 2.4.1 & 2.4.2). In tall vessels and
when antenna is mounted close to the tank wall, improve-
ment in signal quality may be attained by rotating the
launcher to 90 degrees.
Signal Loss: If the Level signal is lost repeatedly at a specific
point in the vessel, it is usually a symptom that multipath
(side-wall reflections) are causing cancellation by returning
to the transmitter exactly 180° out of phase with the Level
signal. Utilize the following procedure
• Go to transmitter screen #4 which shows both Level and
signal Quality.
• Bring the Level up (or down) to the exact point where the
signal is repeatedly lost. Monitor the Quality value as this
point is being approached. The Quality value will degrade
to a low point before it begins to increase.
• At the point of poorest Quality, loosen both the Universal
connector and the set screw. Slowly rotate the launcher
clockwise approximately 10–20° (the transmitter can be
rotated independently). Allow the unit to stabilize for
approximately 1 minute. Repeat this process until the signal
Quality value is optimized.
• Without disturbing the position of the launcher, position
the transmitter head back to its most convenient location.
• Tighten both the Universal connector (30 ft-lbs of force) and
Launcher set screw.

2.5 Wiring
Caution The PULS R Radar transmitter operates at voltages of
16–36 VDC (GP), 16-28.6 VDC (IS) and 16–36 VDC (XP).
Higher voltage will damage the transmitter.
Wiring between the power supply and the Radar transmitter
should be made using 18–22 AWG shielded twisted pair
instrument cable. Within the transmitter enclosure, con-
nections are made to the terminal strip and the ground
connections. The directions for wiring the Radar transmitter
depend on the application
• General Purpose or Non-incendive (Cl I, Div. 2)
• Intrinsically Safe
• Explosion Proof
NOTE: For TEX/IEC installation guidelines refer to bulletin BE 58-601.
WARNING! Explosion hazard. Do not remove covers unless power
has been switched off or the area is known to be non-
hazardous.
2.5.1 General Purpose or Non-incendive (Cl , 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. If flammable
media is contained in the vessel, the transmitter must be
installed per Cl I, Div. 1 standards of area classification.
To install General Purpose or Non-incendive wiring:
1. Remove the cover to the wiring compartment of the trans-
mitter. Install the conduit plug in the unused opening.
2. Install a conduit fitting and pull the supply wires.
3. Connect shield to an earth ground at power supply and
leave floating at the transmitter.
4. Connect an earth ground wire to the nearest green ground
screw per local electrical code (not shown in illustration).
5. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.
6. Replace cover to the wiring compartment of transmitter.
2.5.2 ntrinsically Safe
An intrinsically safe (IS) installation potentially has flam-
mable media present. An approved IS barrier must be
installed in the non-hazardous (safe) area.

17
58-601 Pulsar®Radar Transmitter
To install Intrinsically Safe wiring:
1. Make sure the IS barrier is properly installed in the safe
area (refer to local plant or facility procedures). Complete
the wiring from the barrier to the Radar transmitter.
2. Remove the cover to the wiring compartment of the trans-
mitter. Install the conduit plug in the unused opening.
3. Install a conduit fitting and pull the supply wires.
4. Connect shield to an earth ground at power supply and
leave floating at the transmitter.
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 the cover to the wiring compartment of the
transmitter.
2.5.3 Explosion Proof
Explosion Proof (XP) is a method of designing equipment
for installation in 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 trans-
mitter must be contained in Explosion Proof conduit
extending into the safe area. Due to the specialized design
of the Radar transmitter, no Explosion Proof conduit fit-
ting (EY seal) is required within 18" of the transmitter.
An Explosion Proof conduit fitting (EY seal) is required
between the hazardous and safe areas.
To install Explosion Proof wiring:
1. Install Explosion Proof conduit from the safe area to the
conduit connection of the Radar transmitter (refer to local
plant or facility procedures).
2. Remove the cover to the wiring compartment of the
transmitter.
3. Connect shield to an earth ground at the power supply
and leave floating at the transmitter.
4. Connect an earth ground wire to the nearest green
ground screw per local electrical code (not shown in
illustration).
5. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.
6. Replace the cover to the wiring compartment of the
transmitter.

2.6 Configuring the Transmitter
The Radar transmitter comes factory-calibrated and can be
configured in minutes for specific applications.
Before configuring the transmitter, collect the operating
parameters information. Then, power-up the transmitter
on the bench and follow through the step-by-step proce-
dures for the menu-driven transmitter display. Information
on configuring the transmitter using a HART communica-
tor is given in Configuration Using HART (Section 2.7).
2.6.1 Operating Parameters
Some key information is needed to configure the Radar
transmitter. If necessary, complete the configuration infor-
mation table in Section 1.1.2.
2.6.2 Setting Up for Shop Configuration
The Radar transmitter can be configured at a test bench by
connecting a 24 VDC power supply directly to the trans-
mitter terminals. The connections are illustrated in the
accompanying diagrams. An optional digital multimeter is
shown if current measurements are desired.
NOTE: Current measurements taken at these test points is an approx-
imate value. ccurate current readings should be taken with
the digital multimeter in series with the loop.
1. When using a HART communicator for configuration, a
minimum 250 Ωline load resistance is required. See the
HART communicator manual for more information.
2. The transmitter can be configured without the antenna,
but disregard error messages due to the unattached antenna.
Radar transmitter may indicate a LEVEL value >0 when
disconnected from antenna.
2.6.3 Transmitter Display and Keypad
The Radar transmitter has a liquid-crystal display (LCD)
capable of showing two lines of 8 characters each.
Transmitter measurements and configuration menu screens
are shown on the LCD.
The transmitter default display is the measurement screen.
It cycles every 5 seconds to display LEVEL, %OUTPUT,
QUALITY, and LOOP information. The transmitter
defaults to this display after 5 minutes if no keystrokes are
sensed with the exception of LEVEL, DISTANCE,
%OUTPUT, QUALITY, and LOOP screens. The display
will not return to the default screen if left in one of these
screens.

display line).
2.6.4 Password Protection (Default = 0)
The Radar transmitter is password protected to restrict
access to certain portions of the menu structure that affect
the operation of the system. When the proper password is
entered, an exclamation point (!) appears as the last char-
acter of the first line of the display. The password can be
changed to any numerical value up to 255. The password
is required whenever configuration values are changed.
The default password installed in the transmitter at the
factory is 0 (password disabled). The last step in the con-
figuration menu provides the option to enter a new pass-
word. If 0 is entered as a password, the transmitter is no
longer password protected and any value in the menu can
be altered (except diagnostic values) without entering a
confirming password.
NOTE: If the password is not known, the menu item New Password
displays an encrypted value representing the present pass-
word. Call the factory with this encrypted value to determine
the actual password.
The keypad has three arrows used to scroll through the
displays and to calibrate the transmitter – the Up and
Down Arrow ( ) keys and the Enter ( ) key.
