2.0 Complete Installation
This se tion provides detailed pro edures for properly
installing, wiring, onfiguring, and, as needed, troubleshoot-
ing the PULSAR Model R86 Radar Level Transmitter.
2.1 Unpacking
Unpa k the instrument arefully. Make sure all omponents
have been removed from the pa king material. Che k all on-
tents against the pa king slip and report any dis repan ies to
the fa tory.
Before pro eeding with the installation, do the following:
• Inspe t all omponents for damage. Report any damage to
the arrier within 24 hours.
• Make sure the nameplate model number on the antenna and
transmitter agree with the pa king slip and pur hase order.
• To avoid moisture ingress in the housing, overs should be
fully tightened at all times. For the same reason, plugs should
remain properly installed in the able entries until repla ed
with a able gland
• Re ord the model and serial numbers for future referen e
when ordering parts.
2.2 Electrostatic Discharge (ESD)
Handling Procedure
MAGNETROL ele troni instruments are manufa tured to
the highest quality standards. These instruments use ele troni
omponents that may be damaged by stati ele tri ity present
in most work environments.
The following steps are re ommended to redu e the risk of
omponent failure due to ele trostati dis harge.
• Ship and store ir uit boards in anti-stati bags. If an anti-sta-
ti bag is not available, wrap the board in aluminum foil. Do
not pla e boards on foam pa king materials.
• Use a grounding wrist strap when installing and removing
ir uit boards. A grounded workstation is re ommended.
• Handle ir uit boards only by the edges. Do not tou h om-
ponents or onne tor pins.
• Make sure that all ele tri al onne tions are ompletely made
and none are partial or floating. Ground all equipment to
a good, earth ground
WARNING! Potential ele trostati harging hazard. Do not rub
with dry loth.

2.3 Before You Begin
2.3.1 Site Preparation
Ea h PULSAR Model R86 Radar transmitter/antenna is
built to mat h the physi al spe ifi ations of the required
installation. Ensure that the antenna pro ess onne tion is
orre t for the threaded or flanged mounting on the vessel
where the transmitter will be pla ed. See Se tion 2.4,
Mounting.
Ensure that all lo al, state, and federal regulations and guide-
lines are observed. See Se tion 2.5, Wiring.
Ensure that the wiring between the power supply and
PULSAR Model R86 Radar transmitter is omplete and or-
re t for the type of installation. See Se tion 3.6, Specifications.
2.3.2 Equipment and Tools
No spe ial tools are required. The following items are
re ommended:
• Threaded antenna and
pro ess onne tion. . . . . . . . . . . . . 2 1/8" (54 mm) wren h
• Transmitter/antenna onne tion . . 1 1/2" (38 mm) wren h
• Torque wren h . . . . . . . . . . . . . . . . . . . . . . highly desirable
• Flat-blade s rewdriver
• Digital multimeter or volt/ammeter . . . . . . . . . . . Optional
• 24 VDC (23 mA) power supply . . . . . . . . . . . . . . Optional
2.3.3 Operational Considerations
Radar appli ations are hara terized by three basi ondi-
tions;
• Diele tri (pro ess medium)
• Distan e (measuring range)
• Disturban es (turbulen e, foam, false targets, multiple refle -
tions and rate of hange).
The PULSAR Model R86 Radar transmitter is offered with
a horn antenna onfiguration—Horn (1 1/2", 2", 3", 4").
Ideally, if the installation allows, the 4" horn antenna should
be used to ensure the best possible performan e in all opera-
tional onditions.

14 BE 58-603 Pulsar® Model R86 Radar Transmitter
2.3.3.1 Maximum Distance
The hart below shows the maximum measuring range
(Distan e) of ea h antenna based on fundamental onditions
of Diele tri , Distan e and Turbulen e. Distan e is measured
from the Sensor Referen e Point (bottom of NPT thread, top
of BSP thread or fa e of a flange).
2.3.3.2 Minimum Distance
Liquid should not be allowed loser dan:
For Metal Antennas:
50 mm (2") from the bottom of the antenna or 300 mm
(12") from the sensor referen e point (whi hever is greater).
Refer to illustration at left.
For Encapsulated Horn Antennas:
50 mm (2") from the bottom of the antenna or 300 mm
(12") from the laun h point (whi hever is greater). Refer to
illustration at left.
2.3.3.3 Problematic Applications; GWR Alternative
Some appli ations an be problemati for Non-Conta t
Radar. For these, Guided Wave Radar is re ommended:
• Extremely low diele tri media (εr<1.7)
• Stillwells, standpipes, bridles, ages and bypass olumns.
• Very weak refle tions from the liquid surfa e (parti ularly
during turbulen e) an ause poor performan e.
• Tanks heavily luttered with false targets (mixers, pumps, lad-
ders, pipes, et .)
• During times of very low liquid levels of low diele tri media,
the metal tank bottom may be dete ted whi h an deteriorate
performan e.
• Foam an either absorb or refle t the mi rowave energy depend-
ing upon the depth, diele tri , density and wall thi kness of the
bubbles. Due to typi al variations in the amount (depth) of foam,
it is impossible to quantify performan e. It may be possible
to re eive most, some or none of the transmitted energy.
• When measurement lose to flange is riti al
Extremely high liquid levels (Overflow) onditions when
liquid very near the antenna an ause erroneous readings
and measurement failure.

2.4 Mounting
The PULSAR Model R86 Radar transmitter an be mount-
ed to a vessel using a variety of pro ess onne tions.
Generally, either a threaded or flanged onne tion is used.
For information about the sizes and types of onne tions
available, see Se tion 3.8.2, Antenna Mode Numbers.
2.4.1 Installing the Antenna
Before installing, ensure that:
• Model and Serial numbers on the nameplates of the
PULSAR Model R86 transmitter and antenna are identi al.
• Pro ess temperature, pressure, diele tri , turbulen e and
distan e are within the antenna spe ifi ations for the
installation.
• Prote tive ap is kept on the antenna if the transmitter is to
be installed at a later time.
• Antenna is being mounted in the optimal lo ation. See fol-
lowing se tions: Location, Beam Ang e, Obstructions and
Nozz es for spe ifi information.
• If the liquid level omes in onta t with the antenna, noise
and media buildup drasti ally de rease reliable measurement.
Liquid should not be allowed loser than 50 mm (2") from
the bottom of the antenna or 300 mm (12") from the sensor
referen e point, whi hever is greater.
2.4.1.1 Location
Ideally, the Radar transmitter should be mounted providing
an unobstru ted signal path to the liquid surfa e where it
should illuminate (with mi rowave energy) the largest,
possible surfa e area. See Se tion 2.4.1.2, Beam Ang e.
Unavoidable obsta les will produ e refle tions that must be
minimized during field onfiguration. See Se tion 3.3.3,
Echo Rejection. Mount in a lo ation equal to 1/2 the radius of
tank top. Do not mount in enter of vessel nor loser than 45
m (18") of tank wall. Conta t Magnetrol Te hni al Support
when mounting loser than 45 m (18") is required.
2.4.1.2 Beam Angle
The various horn antennas exhibit slightly different beam pat-
terns. Ideally, the beam pattern should illuminate with
mi rowave beam the maximum liquid surfa e with minimum
onta t with other obje ts in the vessel in luding the tank wall.
Use the hart at left to determine the optimum installation lo a-
tion.

2.4.1.3 Obstructions
Almost any obje t that falls within the beam pattern will
ause refle tions that may be misinterpreted as a false liquid
level. Although PULSAR Model R86 has a powerful E ho
Reje tion routine, all possible pre autions should be taken to
minimize false target refle tions with proper installation and
orientation. Refer to Se tion 4.0, Advanced Configuration/
Troub eshooting Techniques for additional information.
2.4.1.4 Nozzles
Improper installation in a nozzle an reate “ringing” that will
adversely affe t measurement. The antenna should always be
mounted so the a tive se tion of the antenna is a minimum
of 13 mm (0.5") outside the nozzle. Antenna extensions are
offered to allow the PULSAR Model R86 transmitter to work
reliably in nozzles up to 1,8 m (72"). See Se tion 3.6.7 for
dimensional drawings of all antenna designs in luding nozzle
extensions.
Be sure to include any nozzle distance extending within
the vessel.
2.4.1.5 Standpipes and Stillwells
The PULSAR Model R86 an be mounted in a standpipe
or stillwell but ertain items must be onsidered:
•
Metal stillwells only: inside diameter 45–200 mm (1 3/4"–
8").
• Diameter must be onsistent throughout length; no redu ers
or gaps.
• Stillwell length must over omplete range of
measurement (i.e., liquid must be in stillwell).
• Welds should be smooth.
• Vents: holes < 3 mm (0.125") diameter,
slots < 3 mm (0.125") 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 in lude a non-zero entry for
PIPE I.D parameter.
2.4.2 Installing the Transmitter
• Remove the prote tive plasti ap from the top of antenna.
Store the ap in a safe pla e in ase the transmitter has to be
removed later.
• Carefully pla e the transmitter on the antenna.
• Rotate the transmitter to fa e the most onvenient dire tion
for wiring, onfiguration and viewing.

NOTE: ALWAYS RUN THE ECHO REJECTION ROUTINE AFTER MAKING
CHANGES TO MENU ITEMS (Antenna Model, Antenna
Extension, Antenna Mount, Tank Height, Blocking Distance,
Dielectric, Turbulence, Rate of Change, Foam).
2.4.2.1 Low Echo Margin
E ho Margin is a parameter that, when used with E ho
Strength, an be a very useful troubleshooting tool. It is
defined as a numeri value that is related to the strength of
the target peak relative to the Level Threshold or ompeting
waveform features, i.e., noise.
Echo Loss: If the Level signal is lost repeatedly at a spe ifi
point in the vessel, it is usually a symptom of multipath (side-
wall) refle tions ausing an ellation by returning to the
transmitter exa tly 180° out of phase with the a tual Level
signal. This an be improved by applying the following pro-
edure:
• S roll to Display Config Menu under Devi e Setup. S roll
down to E ho Strength and E ho Margin and hange the set-
tings from Hide to View. This will allow you to view these
values from the home s reen.
• Bring the Level up (or down) to the exa t point where the sig-
nal is repeatedly lost. Monitor the E ho Margin value as this
point is being approa hed. The E ho Margin value will
degrade to a low point before it begins to in rease.
• Refer to Se tion 4.4 for additional information.

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 dam-
age the transmitter.
Wiring onne tions between the power supply and the
PULSAR Model R86 Radar Transmitter should be made
using 0.5–1 mm2(18–22 AWG) shielded twisted pair instru-
ment able. Conne tions are made to the terminal strip and
the ground onne tions within the top en losure ompart-
ment. Wiring onne tions are to be torqued to a minimum
of 0,79 N m (7 in. lbs.) and shall not ex eed 1,13 N m (10 in.
lbs.).
The instru tions for wiring the PULSAR Model R86 trans-
mitter depend on the appli ation:
• General Purpose or Division 2
• Intrinsi ally Safe
• Explosion Proof
WARNING! Explosion hazard. Do not dis onne t equipment unless
power has been swit hed off or the area is known to be
non-hazardous.
To avoid moisture ingress in the housing, overs should be
fully tightened at all times. For the same reason, able gland
and plugs should be properly installed in the able entries.
2.5.1 General Purpose or Division 2
A general purpose installation does not have flammable
media present.
Areas rated Division 2 have flammable media present only
under abnormal onditions.
24 VDC ele tri al onne tions are required.
Caution: If flammable media is ontained in the vessel, the trans-
mitter must be installed per Class I, Div 1 standards of
area lassifi ation.
To install General Purpose or Division 2 wiring:
1. Remove the over from the wiring ompartment of the
transmitter. Install the onduit plug in the unused opening
and use PTFE tape/sealant to ensure a liquid-tight
onne tion.
2. Install a onduit fitting and pull the supply wires.
3. Conne t shield to an earth ground at power supply.
4. Conne t an earth ground wire to the nearest green ground
s rew (not shown in illustration).
5. Conne t the positive supply wire to the (+) terminal and the
negative supply wire to the (-) terminal.
6. Repla e and tighten the over to the transmitter wiring
ompartment before applying power.

2.5.2 Intrinsically Safe
An Intrinsi ally Safe (IS) installation potentially has flam-
mable media present. An approved IS barrier must be
installed in the non-hazardous (safe) area to limit the avail-
able energy out to the hazardous area.
See Agency Drawing – Intrinsica y Safe Insta ation,
Se tion 3.5.1.
To install Intrinsically Safe wiring:
1. Ensure that the IS barrier is properly installed in the safe
area (refer to lo al plant or fa ility pro edures). Complete
the wiring from the power supply to the barrier and from
the barrier to the PULSAR Model R86 transmitter.
2. Remove the over from the wiring ompartment of the
transmitter. Install the onduit plug in the unused opening
and use PTFE tape/sealant to ensure a liquid-tight
onne tion.
3. Install a onduit fitting and pull the supply wires.
4. Conne t shield to an earth ground at power supply.
5. Conne t an earth ground wire to the nearest green ground
s rew (not shown in illustration).
6. Conne t the positive supply wire to the (+) terminal and the
negative supply wire to the (-) terminal.
7. Repla e and tighten the over to the wiring ompartment 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 lo ation is an area in
whi h flammable gases or vapors are (or may be) present in
the air in quantities suffi ient to produ e explosive or
ignitable mixtures.
The wiring for the transmitter must be ontained in
Explosion Proof onduit extending into the safe area.
• Due to the spe ialized design of the PULSAR Model R86
transmitter, no Explosion Proof onduit fitting (EY seal) is
required within 45 m (18") of the transmitter.
• An Explosion Proof onduit fitting (EY seal) is required
between the hazardous and safe areas. See Se tion 3.5,
Agen y Spe ifi ations.

2.6 Configuring the Transmitter
Although the PULSAR Model R86 transmitter an be
delivered pre- onfigured from the fa tory, it an also be eas-
ily re onfigured in the shop or at the installation using the
lo al LCD/Keypad or PACTware/DTM. Ben h onfigura-
tion provides a onvenient and effi ient way to set up the
transmitter before going to the tank site to omplete the
installation.
Before onfiguring any transmitter, olle t all operating
parameters information (refer to Se tion 1.1.2).
Apply power to the transmitter and follow the step-by-step
pro edures for the menu-driven transmitter display. Refer to
Se tions 2.6.2 and 2.6.4.
Information on onfiguring the transmitter using a HART
ommuni ator is given in Se tion 2.7, Configuration Using
HART.
Refer to I/O manual BE 58-641 for information on
FOUNDATION Fieldbus™output.
2.6.1 Bench Configuration
The PULSAR Model R86 transmitter an be easily onfig-
ured at a test ben h by onne ting a standard 24 VDC
power supply dire tly to the transmitter terminals as shown
in the a ompanying diagram. An optional digital multime-
ter is shown in the event that mA urrent measurements are
desired.
NOTE: Current measurements taken at these test points are an
approximate value. A urate urrent readings should be
taken with the digital multimeter dire tly in series with the
loop.
