Complete Installation
This section provides detailed procedures for properly
installing, configuring, and, as needed, troubleshooting the
Kotron® Series 82 CE RF Level Transmitter.
1.1
Unpacking
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 agrees with the
packing slip and purchase order.
• Record the model and serial numbers for future reference
when ordering parts.
1.2
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.

50-613 Kotron® Series 82 CE RF Level Transmitter
1.3
Installation Location
KOTRON RF Transmitters should be located for easy
access for service, calibration and monitoring. Units
should not be exposed to ambient temperatures below
-40° F (-40° C) or above +160° F (+70° C). Special precaution should be made to prevent exposure to corrosive
atmosphere, excessive vibration, shock or physical damage.
Caution: This unit contains CMOS electronics which may be
damaged by static electricity. Do not touch any
semi-conductor devices unless you are properly
grounded.
1.4
Mounting
The Series 82 CE transmitter can be mounted to a tank
using a variety of process connections.
Make sure all mounting connections are properly in place
on the tank before installing the probe. Make sure the
KOTRON probe is correct for the intended installation.
It is common practice to use the metal tank wall as the
reference electrode. In such cases, it is required that the
probe housing makes a good electrical connection to the
tank wall. If there is any doubt about this connection or
to the use of PTFE thread tape gaskets, paint, rust, or any
other reason, a separate strap should be installed between
the probe housing and the tank.
Caution: This unit contains CMOS electronics which may be
damaged by static electricity. Do not touch any semiconductor devices unless you are properly grounded.
Caution: When a probe is used in an abrasive medium, inspect the
probe periodically for visible surface wear. If damage to
the probe insulation is found, replace the probe.
1.4.1 Metal Walled Tanks
On water-based liquids, there should be no problem with
sensitivity. With non-conductive, low dielectric media,
sensitivity can be enhanced by locating the probe close to
and parallel with the tank wall. If this is not practical, a
ground reference probe may be the solution.

1.4.2 Non-Metallic and Glass-Lined Tank Construction
With plastic, concrete, wood, or any other non-conductive
walled vessels, a ground reference is required. Most commonly, this electrode will be in the form of a concentric
ground tube (i.e. stilling well). In questionable circumstances, consult the factory. In all cases, a good electrical
connection must be made between the ground surface and
the probe housing.

1.4.3 Transmitter/Probe Assembly
Transmitters with probes up to and including 12 inches
(300 mm) in length are shipped pre-assembled. All other
transmitters are shipped unassembled to avoid damage
during transit. These transmitters must be assembled prior
to mounting. Choose your particular configuration from

Calibration
There are two calibration methods that can be used,
depending on your particular situation. Calibration
Procedure A will require moving the level from the 0%
point (4 mA) to the 100% point (20 mA). Calibration
Procedure B allows you to start at a level greater than 0%
and stop at a level less than 100%. To attain the best
accuracy and linearity use Calibration Procedure A. The
following is a list of abbreviations and definitions used in
the procedures.
L0 The level of the media in the vessel which corresponds
to the 0% (4 mA) point
L1 A media level higher than L0
L3
100%
L2
less than 100%
L2 A media level higher than L0 and L1 but less than L3

The output current can be measured either by inserting
a milliammeter into the loop, or by measuring across
TP1 (+) and TP2 (–). The intensity of the LED between
the test points is a relative indicator of current flow. (The
LED will not light with a meter across the test points.)

1.7.1 Calibration Procedure A
1. Move the media level in the vessel to the 0% (4 mA) point.
2. Turn potentiometer Zero Coarse counterclockwise until
the loop output is between 4.00 mA and 4.50 mA.
3. If the loop current can not be decreased to at least 4.50 mA,
turn the Zero Coarse potentiometer fully clockwise, close
DIP switch positions “MED” and “HIGH” sequentially
(ONLY ONE SWITCH POSITION SHOULD BE
CLOSED AT A TIME—THE OTHER TWO POSITIONS
MUST REMAIN OPEN). Repeat Step 2. See Figure 10.
4. Turn potentiometer Zero Fine counterclockwise until the
loop output reads exactly 4.00 mA.
5. Move the media level in the vessel to the 100% (20 mA)
point.
6. Turn the Span Fine potentiometer counterclockwise until
the loop current is exactly 20.00 mA.
50-613 Kotron® Series 82 CE RF Level Transmitter
7. If 20 mA cannot be reached, individually close Span
Coarse DIP switches (in sequence), #1, #2, and #3, until
the loop current is close to (and not less than), 20 mA.
(ONLY ONE SWITCH POSITION SHOULD BE
CLOSED AT A TIME—THE OTHER TWO
POSITIONS MUST REMAIN OPEN).
8. Turn the Span Fine potentiometer counterclockwise until
the loop current is exactly 20.00 mA. If 20 mA cannot be
reached, repeat Step 6.
Calibration is now complete.
1.7.2 Calibration Procedure B
1. Move the media level in the vessel to the lowest level you
can set.
2. To determine the correct output level at this point, use the
following formula:
(L1 - L0)
L1mA = ( (L3 - L0) x 16) + 4
3. Turn the Zero Coarse potentiometer counterclockwise
until the loop output is between L1mA and
L1mA + 0.5 mA.
4. If the loop current output cannot be decreased to at least
L1mA + 0.5 mA, turn the Zero Coarse potentiometer
fully clockwise, close Zero Coarse DIP switch positions #2
and #3 sequentially (ONLY ONE SWITCH POSITION
SHOULD BE CLOSED AT A TIME—THE OTHER
TWO POSITIONS MUST REMAIN OPEN). Repeat
Step 3. See Figure 10.
5. Turn potentiometer Zero Fine counterclockwise until the
loop output reads exactly L1mA.
6. Move the media level in the vessel to the highest level you
can set.
7. To determine the correct output level at this point, use the
following formula:
(L2 - L0)
L2mA = ( (L3 - L0) x 16) + 4
8. Turn the Span Fine potentiometer counterclockwise until
the loop current reaches the desired value calculated
(L2mA) in Step 7.
9. If the desired value cannot be obtained, individually close
the Span Coarse DIP switches #1, #2, and #3, until the
loop current is as close to (and not less than), L2mA.
(ONLY ONE SWITCH POSITION SHOULD BE
CLOSED AT A TIME—THE OTHER TWO POSITIONS MUST REMAIN OPEN).
10. Turn the Span Fine potentiometer counterclockwise until
the loop current is exactly L2mA.
Calibration is now complete.

Reference Information
This section presents an overview of the operation of the
KOTRON Series 82 CE RF Level Transmitter, information
on troubleshooting common problems, intrinsic safety
information, physical, functional and performance
specifications, listings of agency approvals, and a list
of recommended parts.
2.1
Description
KOTRON Series 82 CE Level Transmitters are designed to
measure liquids, slurries, dry-bulk, or liquid-liquid interfaces. The transmitter may be mounted integrally with the
probe or can be remote mounted up to 40 feet (12 meters)
away. This unit is available as a four-wire transmitter with
either 120 VAC or 240 VAC input power, or as a two-wire
transmitter with a supply voltage between 16 VDC and
40 VDC. Available options include an analog meter. This
transmitter can be used with any KOTRON R.F.
Capacitance probe.
2.2
Theory of Operation
The KOTRON Series 82 CE Level Transmitter monitors
the level by determining the capacitance of the media. The
probe and a ground (usually the metal tank wall), form
a capacitor. As the level rises and falls in the tank, the
amount of capacitance developed between the probe
and the ground changes. This change of capacitance is
converted to a proportional 4–20 mA signal.
2.3
Troubleshooting
The output current can be measured either by inserting
a milliammeter into the loop, or by measuring across
TP1 (+) and TP2 (–). The intensity of the LED between
the test points is a relative indicator of current flow.
Caution: When a probe is used in an abrasive medium, inspect the
probe at least annually for visible surface wear. In case any
wear is found, replace the probe or consult the factory.
2.3.1 Installation

Return Material Procedure
Service Policy
Owners of Magnetrol may request the return of a control
or any part of a control for complete rebuilding or replacement. They will be rebuilt or replaced promptly. Controls
returned under our service policy must be returned by
Prepaid transportation. MAGNETROL will repair or
replace the control at no cost to the purchaser (or owner)
other than transportation if:
®
1. Returned within the warranty period; and
2. The factory inspection finds the cause of the claim to
be covered under the warranty.
If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be
charges for labor and the parts required to rebuild or
replace the equipment.
In some cases it may be expedient to ship replacement
parts; or, in extreme cases a complete new control, to
replace the original equipment before it is returned. If this
is desired, notify the factory of both the model and serial
numbers of the control to be replaced. In such cases, credit
for the materials returned will be determined on the basis
of the applicability of our warranty.
No claims for misapplication, labor, direct or consequential damage will be allowed.
So that we may efficiently process any materials that are
returned, it is essential that a “Return Material
Authorization” (RMA) number be obtained from the factory, prior to the material's return. This is available
through your MAGNETROL local representative or by
contacting the factory. Please supply the following information:

Description of Material
Serial Number
Reason for Return
Application
Any unit that was used in a process must be properly
cleaned in accordance with OSHA standards, before it is
returned to the factory.
A Material Safety Data Sheet (MSDS) must accompany
material that was used in any media.
All shipments returned to the factory must be by prepaid
transportation.
All replacements will be shipped F.O.B. factory.
