2.3
Before You Begin
2.3.1 Site Preparation
Each E3 Modulevel transmitter is built to match the physical specifications of the required installation. Ensure that
the process connection(s) on the vessel matches the
Modulevel’s process connection(s).
See Mounting, Section 2.4.
Ensure that the wiring between the power supply and
Modulevel transmitter are complete and correct for the type
of installation.
See Wiring, Section 2.5.
When installing the Modulevel transmitter in a general purpose or hazardous area, local, state and federal regulations
and guidelines must be observed.
See Wiring, Section 2.5.
2.3.2 Equipment and Tools
•
•
•
•
•
•
•
No special equipment or tools are required to install the
Electronic Modulevel. The following items are recommended:
Wrenches, flange gaskets and flange bolting appropriate for
process connection(s)
Flat-blade screwdriver
Level
1
⁄8" Allen wrench
Power supply
Multimeter
250 to 450 ohm resistor for transmitters with HART
communication
2.3.3 Operational Considerations
The Modulevel transmitter should be located for easy access
for service, configuration, and monitoring. There should be
sufficient headroom to allow installation and removal of the
transmitter head and, in cases of tank top configuration, the
displacer. Special precautions should be made to prevent
exposure to corrosive atmosphere, excessive vibration, shock,
or physical damage.
The operating temperature range for the transmitter electronics is -40° to +176° F (-40° to +80° C). The operating
temperature range for the digital display is -5° to +160° F
(-20° to +70° C).
Caution: Operation of all buoyancy type level devices should be
done in such a way as to minimize the action of dynamic
forces on the float or displacer sensing element. Good
practice for reducing the likelihood of damage to the control is to equalize pressure across the device very slowly.

48-635 E3 Modulevel Displacer Level Transmitter
2.4
Mounting
The E3 Modulevel transmitter can be mounted to a tank
using a variety of configurations and process connections.
Generally, either a threaded, welded or flanged connection
is used with an external cage. A flanged connection is always
used on a tank top model. For information about the sizes
and types of connections available, see Model Numbers,
Section 3.7.
Ensure all mounting connections are in place on the tank
and properly sized for the specific unit being installed.
Compare the model on the nameplate with the product
information to ensure the Modulevel transmitter is correct
for the intended installation.
If the Modulevel must be insulated, DO NOT insulate the
transmitter head, e-tube or finned extensions.

Configuring the Transmitter
The E3 Modulevel transmitter comes calibrated from the
factory.
Information on configuring the transmitter using a HART
communicator is given in Configuration Using HART,
Section 2.7.
2.6.1 Operating Parameters
Some key information is needed to configure the E3 transmitter. Complete the configuration information table. See
Configuration Information, Section 1.1.2.
2.6.2 Transmitter Display and Keypad
The E3 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 STATUS, LEVEL,
%OUTPUT, and LOOP information. The transmitter
defaults to this display after 5 minutes of keypad inactivity.
The keypad has three butons used to scroll through the disand
keys
plays and to calibrate the transmitter – the
and the
key.

as the last character in the top
display line).

2.6.3 Password Protection (Default = 0)
The E3 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 character 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 configuration menu provides the option to enter a new password. If
0 is entered as a password, the transmitter is no longer password protected and any value in the menu can be altered
(except factory 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 password. Call the factory with this encrypted value to determine
the actual password.
2.6.4 Calibration Defaults
The E3 Modulevel transmitter comes from the factory
already calibrated. The default configuration is set up such
that the level range is the length of the displacer with the
4 mA set point at the bottom of the range and the 20 mA
point at the top. Field calibration is not required, but each
unit must be configured for the process operating conditions. Level measurement applications require that the
operating temperature and operating specific gravity be
entered via the keypad and LCD display. For Interface and
Density measurement applications, only the operating
temperature must be entered.
While not necessary nor recommended, the E3 Modulevel
can be calibrated in the actual process. This is accomplished by selecting the User Calibration rather than the
Factory Calibration. Once in the User Calibration, liquid
level can be moved to the low and high calibration points
and the sensor values for the low and high calibration
points can be captured. See procedure on page 36.
2.6.5 Menu: Step-By-Step Procedure
The following table provides a complete explanation of the
software menus displayed by the E3 transmitter. Use this
table as a step-by-step guide to configure the transmitter.
The second column presents the menus shown on the
transmitter display. The displays are in the order they would
appear if the arrow keys were used to scroll through the menu.
16
48-635 E3 Modulevel Displacer Level Transmitter
The numbers are not shown on the display. They are provided as a reference.
The third column provides the actions to take when
configuring the transmitter. Additional information or an
explanation of an action is given in the fourth column.
Configuration tips:
If “Calselct” is Factory, Factory Cal Menu is available for
viewing only. Only calibration parameters in User Cal
Menu can be changed by the user.

Configuration Using HART
Since E3 transmitter supports the HART (Highway
Addressable Remote Transducer) communication protocol,
configuration tools, such as a HART 375 handheld communicator, can be used to provide a communication link to
the E3 transmitter. When connected to the control loop,
the same system measurement readings shown on the transmitter are shown on the communicator. In addition, the
communicator can be used to configure the transmitter.
-
The HART communicator may need to be updated to
include the E3 software (Device Description). Contact your
local HART Service Center for additional information.
+
2.7.1 Connections
A HART communicator can be operated from a remote
location by connecting to a remote junction or by connecting directly to the terminal block in the electronics housing
of the E3 Modulevel transmitter.

HART uses the Bell 202 frequency shift key technique of
high-frequency digital signals. It operates on the 4–20 mA
loop and requires a minimum of 250 Ω load resistance. A
typical connection between a communicator and the
E3 Modulevel transmitter is illustrated.

Description
Display
The E3 Modulevel is a loop-powered, two-wire, 24 VDC
level transmitter which utilizes simple buoyancy principles
in combination with a precision range spring and a highly
accurate LVDT (linear variable differential transformer) to
detect and convert liquid level movement into a stable 4–20
mA output signal. The electronics are housed in an
ergonomic, dual-compartment enclosure which is angled for
ease of wiring and calibration.

Theory of Operation
The Electronic Modulevel Displacer Level Transmitter relies
on the principles of buoyancy to convert mechanical movement to an electronic output. See Figure 14.
3.2.1 Displacer/Range Spring
Displacer
External cage
According to Archimedes principle, the buoyancy force acting on an object immersed in liquid is equal to the mass of
the liquid displaced. As the level changes, the volume of
displacer submerged in the liquid changes, thus varying the
buoyancy force acting on the displacer. This change is
detected by the precision range spring from which the displacer hangs, causing it to elongate or compress. The change
in spring length causes movement of a special LVDT core
which is mounted on a rigid stem attached to the spring.
3.2.2 LVDT
Figure 14

Components
48-635 E3 Modulevel Displacer Level Transmitter
E3 Modulevel utilizes highly precise LVDT technology to
convert the movement of the LVDT core within the LVDT
to a stable 4–20 mA output signal. The position of the core
with respect to a primary and two secondary windings within the LVDT, induces a voltage in each winding. The comparison of the induced voltages within the microprocessor
of the E3 results in very accurate level output.
27
3.2.3 Interface
E3 Modulevel is capable of tracking the interface level of
two immiscible liquids with different densities. Each unit is
custom-made with a displacer specially designed for the
user’s application. This allows it to detect the position of a
clean interface or an emulsion layer and convert it into a
stable 4–20 mA signal. Contact the factory for assistance in
specifying an E3 for interface service. Note that for proper
interface detection, the entire displacer must always be
immersed in liquid.
3.2.4 Density
Yet another capability of E3 Modulevel is to track the
changing density of a liquid over a known density range and
convert that into a stable 4–20 mA output signal. As the
density of the liquid changes, so does the mass of the liquid
displaced by the specially designed displacer. The resulting
change in buoyancy force on the displacer causes the movement of the LVDT core necessary to convert the density
change to the 4–20 mA signal.
3.3
Troubleshooting
The E3 Modulevel displacer transmitter is designed, engineered and constructed for trouble-free operation over a
wide range of operating and application conditions. Below,
common transmitter problems are discussed in terms of
their symptoms and corrective actions.
WARNING! Explosion hazard. Do not remove covers unless power
has been switched off or the area is known to be nonhazardous.
Use of the included PACTware™ PC program is highly
recommended and invaluable for troubleshooting and
advanced calibration. A HART RS232 or USB modem
(purchased separately) is required. See Magnetrol
PACTware™ bulletin 59-101.
WARNING! Other than operation of the push-buttons to enter parameter data, live maintenance is not permitted.

3.5.2 User Calibration Procedure
The E3 Modulevel is calibrated at the factory, so it normally requires only configuration by the user in
the field. Should the E3 require replacement of any parts in the field, a user calibration must be performed after changing out any of the following original parts: Bezel assembly, LVDT assembly, range
spring, stem assembly, or displacer. The following procedure should be followed when performing a
user calibration in the field. Note: User calibration should be performed at normal operating conditions.
1. Move liquid level on displacer to desired low level point. Using keypad and LCD display, scroll down to DispFact.
2. Press

48-635 E3 Modulevel Displacer Level Transmitter
Intrinsic Safety A design or installation approach that limits
the amount of energy that enters a hazardous area to eliminate the potential of creating an ignition source.
Range The maximum value to which the control may sense
level. In the case of the Modulevel, this value is limited to the
physical size of the displacer.

LVDT Linear Variable Differential Transformer This is the
mechanism by which the Electronic Modulevel measures liquid level. This type of transformer compares the currents
induced in two secondary windings to determine the position
of the transformer core and, therefore, the liquid level.
Measured Value The typical measurement values used to
track the level of a process: Level, % Output and Loop.
Media The liquid material being measured by the level
transmitter.
Multidrop The ability to install, wire, or communicate with
multiple devices over one cable. Each device is given a unique
address and ID.

from and minimize the effects of turbulence in the vessel. To
ensure that the level in the well is identical to that outside the
well, it must have vent holes included near the top to allow
escape of vapor trapped above the liquid level.
Transformer An electrical device which transfers electrical
energy from a primary winding to one or more secondary
windings by magnetic induction (no electrical contact)
Trim 4/Trim 20 Built-in system capability to fine tune the
4 mA and 20 mA points so the transmitter output
corresponds exactly to user’s meter, DCS input, etc.
Two Wire An electrical instrument design that uses one set
of wires to provide both the supply power and process measurement signal. The process measurement is achieved by varying the current of the loop. Also called Loop Powered.
Units The engineering units used to measure the level in
the system.
Warning (message) The second level in the hierarchy of

ASSURED QUALITY & SERVICE COST LESS
Service Policy
Return Material Procedure
Owners of Magnetrol controls 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:
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 a Magnetrol local representative or by
contacting the factory. Please supply the following
information:
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.
