tighten as this may ause damage to the plasti threads.
4. Adjust the beam position by turning the internal laun her
adjustment (Fig ??). The internal laun her adjustment is
numbered 1-18 that equates to 10-180 degrees of adjust-
ment; 9 is the midpoint where long axis of the beam is at
45 degrees to the Display (Fig ??). After positioning the
transmitter display, rotate the laun her adjustment so the
beam is at an angle of 45° to a line from the radar unit to
the nearest tank wall (Fig ??). Do not optimize the Quality
(signal strength) at one level in the vessel.
• Do not pla e insulating material around any part of the
Radar transmitter in luding the antenna pro ess onne tion.

2.0 Complete Installation
This se tion provides detailed pro edures for properly
installing, onfiguring, and, as needed, troubleshooting the
R82 Radar Level Transmitter.
2.1 npacking
Unpa k the instrument arefully. Make sure all omponents
have been removed from the pa king material. Che k all the
ontents 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 transmitter
agree with the pa king slip and pur hase order.
• Re ord the model and serial numbers for future referen e
when ordering parts.
2.2 Electrostatic Discharge (ESD)
Handling Procedure
Magnetrol’s 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 pres-
ent 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-
stati 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
omponents or onne tor pins.
• Make sure that all ele tri al onne tions are ompletely
made and none are partial or floating. Ground all equip-
ment to a good, earth ground.

2.3 Before You Begin
2.3.1 Site Preparation
Ea h R82 Radar transmitter is built to mat h the spe ifi
physi al spe ifi ations of the required installation. Make
sure the antenna onne tion is orre t for the threaded or
flanged mounting on the vessel or tank where the transmit-
ter will be pla ed. See Mounting, Se tion 2.4.
Make sure that the wiring between the power supply and
Radar transmitter are omplete and orre t for the type of
installation.
When installing the Radar transmitter in a general purpose
or hazardous area, all lo al, state, and federal regulations and
guidelines must be observed. See Wiring, Se tion 2.5.
2.3.2 Equipment and Tools
No spe ial tools are needed. The following items are
re ommended:
• Threaded antenna and transmitter . . . . . . 2" (50 mm)
• 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 onditions;
Diele tri , Distan e (measuring range) and Disturban es
(turbulen e, foam, false targets, multiple refle tions and rate
of hange).
2.3.3.1 Maximum Distance
The hart below shows the maximum measuring range
(Distan e) of ea h antenna based on fundamental ondi-
tions of Diele tri , Distan e and Turbulen e. Maximum dis-
tan e is al ulated as Tank Height + Sensor Offset
(see page 17). It 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
If the liquid level is allowed onto the antenna, noise and
media build-up drasti ally de rease reliable measurement.
Liquid should not be allowed loser than 15 in hes
(380 mm) from the bottom of the antenna mounting
threads (or fa e of sanitary flange).

2.3.3.3 Problematic Applications; GW Alternative
Some appli ation on erns an be problemati for Radar.
For these, Guided Wave Radar is re ommended:
• Extremely low diele tri media (εr<2.0)
• 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,
ladders, pipes, et .)
• During times of very low liquid levels of low diele tri media,
the metal tank bottom may be dete ted deteriorating per-
forman e.

• Foam an either absorb or refle t the mi rowave energy
depending 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 per-
forman e. It may be possible to re eive most, some or none
of the transmitted energy.
• Extremely high liquid levels (Overflow) onditions when
liquid very near the antenna an ause erroneous readings
and measurement failure.
2.4 Mounting
The R82 Radar transmitter an be mounted to a vessel
using a variety of pro ess onne tions. Generally, either a
threaded or flanged onne tion is used.
2.4.1 Installing the Antenna
Before installing, make sure:
• Pro ess temperature, pressure, diele tri , turbulen e and
distan e are within the antenna spe ifi ations for the
installation.
• End of antenna is prote ted from bending or breaking.
• Insulating material is not pla ed around any part of the
Radar transmitter in luding the antenna flange.
• Antenna is being mounted in the optimal lo ation. See fol-
lowing se tions: Lo ation, Beam Angle, Obstru tions and
Nozzles for spe ifi information.
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 Angle.
Unavoidable obsta les will produ e refle tions that must be
minimized during field onfiguration. See Se tion 2.6.5.1,
Target Reje tion. Mount in a lo ation equal to 1⁄2the radius
of tank top. Do not mount in enter of vessel nor loser
than 10" (25 m) 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 surfa e with a minimum striking other obje ts in the
vessel in luding the tank wall. Use these drawings to deter-
mine the optimum installation lo ation.

58-610 Model R82 Radar Transmitter
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 Model R82 has a powerful False Target
Reje tion routine, all possible pre autions should be taken
to minimize false target refle tions with proper installation
and orientation.
2.4.1.4 Nozzles
Improper installation in a nozzle reates “ringing” whi h
will adversely affe t measurement. Refer to Figure 9???. Two
Antenna extension lengths are offered to allow the R82
transmitter to work reliably in a variety of nozzles.
The Minimum Blo king Distan e of 15" (380 mm) is
always measured from the bottom of the threads or fa e of
a flange. The related distan e as measured from the end of
the antenna varies depending on the antenna extension
hosen. See Figure ??.
The narrow beam width of the 26 GHz, R82 does allow
mounting so that the antenna an be re essed inside the
nozzle. Optimally, the re essed dimension should never
ex eed 2×the nozzle diameter. See Figure??????
NOTE: If the antenna is recessed in a nozzle it is mandatory that Echo
Rejection is run to eliminate any possibility of false reflections.

2.4.1.5 Standpipes and Stillwells
The R82 an be mounted in a standpipe or stillwell but
ertain onsiderations should be given:
• Metal stillwells only: 2" (S hed 40 max.) to 4" (50–100 mm).
• Diameter must be onsistent throughout length; no redu ers.
• Stillwell length must over omplete range of measurement
(i.e., liquid must be in stillwell).
• Welds should be smooth.
• Vents: holes <0.125" diameter, slots <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.
• Bridles/Bypass Installations: The laun her should be rotated
90° from pro ess onne tions.
• Configuration must in lude an entry for PIPE I.D.
See Se tion 2.6.5.1, Item 34- PIPE I.D.
• There will be some in reased diele tri sensitivity; system
GAIN will be redu ed when PIPE ID >0.
2.4.2 Installing the Transmitter
Install the Transmitter with its integral antenna by threading
into the vessel. DO NOT OVERTIGHTHEN as this may
ause damage to the plasti threads.
• Do not pla e insulating material around any part of the
radar transmitter in luding the antenna flange.
• Installation for NEMA 6P/IP 68- the transmitter an be
installed to allow for temporary submergen e to 6 feet (1.8m):
- use TFE paste to seal onduit entries and antenna pro ess
onne tion
- Do not overtighten housing over; O-ring develops
water-tight seal without ex essive tightening
2.4.2.1 Orientation
The R82 transmitter utilizes a linearly polarized, mi rowave
beam that an be rotated to improve its performan e. Proper
orientation an minimize unwanted target refle tions, de rease
sidewall refle tions (multipath) and maximize dire t refle -
tions from the liquid surfa e.
The internal laun her me hanism an be turned to optimize
performan e. The laun her has index marks numbered
1–18 (representing 10–180 degrees). The Polarization
pattern is at 45 degrees to the transmitter display when
the me hanism is at the #9 position.

2.4.2.2 Initial Installation
Ideally, the transmitter should be mounted half the radius
from the tank wall. In a typi al verti al tank, the Laun her
should be adjusted so the polarization pattern is 45 degrees
to the losest tank sidewall. See Figures ? & ?.
For horizontal ylindri al vessels, aim beam down the long
axis of the vessel. Do not optimize the Quality (signal
strength) at one level in the vessel.
A transmitter mounted within 10" (25 m) of a tank wall
may demand orientation adjustments to limit multipath
and optimize performan e. See Se tion 2.4.2.3, Poor E ho
Strength.
2.4.2.3 Poor Echo Strength
Poor signal quality has many potential auses. Following are
two initial areas for investigation.
Launcher Orientation: Initial laun her orientation is always
45 degrees (see Se tions 2.4.1 & 2.4.2). In tall vessels and
when antenna is mounted lose to the tank wall, improve-
ment in signal quality may be attained by rotating the
laun her to 90 degrees.
Signal Loss: If the Level signal is lost repeatedly at a spe ifi
point in the vessel, it is usually a symptom that multipath
(side-wall refle tions) are ausing an ellation by returning
to the transmitter exa tly 180° out of phase with the Level
signal. Utilize the following pro edure:
• Go to transmitter s reen #5 whi h shows both Level and
E ho Strength.
• Bring the Level up (or down) to the exa t point where the
signal is repeatedly lost. Monitor the E ho Strength this
point is being approa hed. The E ho Strength will degrade
to a low point before it begins to in rease.
• At the poorest E ho Strength slowly rotate the laun her
1–2 not hes. Allow the unit to stabilize for approximately
one minute. Repeat this pro ess until the E ho Strength is
optimized.

2.5 Wiring
Caution The R82 Radar transmitter operates at voltages of 16–36
VDC (GP) and 16-28.6 VDC (IS). Higher voltage will dam-
age the transmitter.
Wiring between the power supply and the Radar transmitter
should be made using 18–22 AWG shielded twisted pair
instrument able. Within the transmitter en losure, on-
ne tions are made to the terminal strip and the ground
onne tions. Trim ex ess wiring to minimize lutter, noise
issues and allow a ess to Laun her adjustment (see
Figure ??). The dire tions for wiring the Radar transmitter
depend on the appli ation:
• General Purpose or Non-in endive (Cl I, Div. 2)
• Intrinsi ally Safe
NOTE: For ATEX installation guidelines refer to bulletin E 58-610.
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-in endive (Cl I, Div. 2) have
flammable media present only under abnormal onditions.
No spe ial ele tri al onne tions are required. If flammable
media is ontained in the vessel, the transmitter must be
installed per Cl I, Div. 1 standards of area lassifi ation.
To install General Purpose or Non-incendive wiring:
1. Remove the over to the wiring ompartment of the trans-
mitter. Install the onduit plug in the unused opening.
2. Install a onduit fitting and pull the supply wires.
3. Conne t shield to an earth ground at power supply and
leave floating at the transmitter.
4. Conne t an earth ground wire to the nearest green ground
s rew per lo al ele tri al ode (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 over to the wiring ompartment of transmitter.

2.6 Configuring the Transmitter
The Radar transmitter omes fa tory- alibrated and an be
onfigured in minutes for spe ifi appli ations.
Before onfiguring the transmitter, olle t the operating
parameters information. Then, power-up the transmitter
on the ben h and follow through the step-by-step pro e-
dures for the menu-driven transmitter display. Information
on onfiguring the transmitter using a HART ommuni a-
tor is given in Configuration Using HART (Se tion 2.7).
2.6.1 Operating Parameters
Some key information is needed to onfigure the Radar
transmitter. If ne essary, omplete the onfiguration infor-
mation table in Se tion 1.1.2.
2.6.2 Setting Up for Shop Configuration
The Radar transmitter an be onfigured at a test ben h by
onne ting a 24 VDC power supply dire tly to the trans-
mitter terminals. The onne tions are illustrated in the
a ompanying diagrams. An optional digital multimeter is
shown if urrent measurements are desired.
When using a HART ommuni ator for onfiguration, a
minimum 250 Ωline load resistan e is required. See the
HART ommuni ator manual for more information.
2.6.3 Transmitter Display and Keypad
The R82 transmitter has a lo al user interfa e onsisting of
a 2-line by 16- hara ter liquid- rystal display (LCD) and
4-push-button keypad. All transmitter measurement data
and onfiguration information is shown in the LCD.
The transmitter default display is the measurement s reen.
It y les every 5 se onds to display *STATUS*, *LEVEL*,
*ECHO STRENGTH*, *%OUTPUT*, *LOOP CUR-
RENT* and *LOCAL TAG* information. The transmit-
ter defaults to this display after 5 minutes if no keystrokes
are sensed. You an also a ess ea h of these s reens indi-
vidually. The display will not return to the default s reen
if left in one of these s reens. For example, the devi e an
be left to read only LEVEL indefinitely if left in this
s reen.

2.6.5 Password Protection (Default = 0)
The Radar transmitter is password prote ted to restri t
a ess to ertain portions of the menu stru ture that affe t
the operation of the system. When the proper password is
entered, an ex lamation point (!) appears as the last hara -
ter of the first line of the display. The password an be
hanged to any numeri al value up to 255. The password
is required whenever onfiguration values are hanged.
The default password installed in the transmitter at the fa -
tory is 0 (password disabled). The last step in the onfigura-
tion menu provides the option to enter a new password. If
0 is entered as a password, the transmitter is no longer pass-
word prote ted and any value in the menu an be altered
(ex ept diagnosti values) without entering a onfirming
password.
NOTE: If the password is not known, the menu item New Password
(Section 2.6.6.1, item #39) displays an encrypted value repre-
senting the present password. Call the factory with this
encrypted value to determine the actual password.
