1.0
Mechanical Installation
This section provides detailed procedures for properly
installing the Electronic Modulevel Displacer Level
Transmitter.
1.1
Unpacking
Unpack the instrument carefully. Take care not to bend the
displacer stem or enclosing tube. Ensure 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.
On chambered units, remove the shipping strap and wire
assembly holding the displacer in place. This assembly
must be removed through the bottom chamber connection
before start-up.
Caution: If reshipping to another location, the displacer
must again be secured using the same strap and
wire assembly.
•
•
Check that the model number on the nameplate matches
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’s electronic instruments are manufactured to the
highest quality standards. These instruments use electronic
components which may be damaged by static electricity
present in most work environments.
•
•
1
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.
48-618 ES/EZ Modulevel Displacer Level Transmitter (Top Hat Assembly Design)
•
•
1.3
Handle circuit boards only by the edges. Do not touch
components or connector pins.
Ensure that all electrical connections are completely made
and that none are partial or floating. Ground all equipment
to a good, earth ground.
Before You Begin
1.3.1 Site Preparation
Each Modulevel transmitter is built to match the specific
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 1.4.
Ensure that the wiring between the power supply and
Modulevel transmitter are complete and correct for the
type of installation.
See Specifications, Section 4.8.
When installing the Modulevel transmitter in a general
purpose or hazardous area, local, state and federal regulations and guidelines must be observed.
See Wiring, Sections 2.0 & 3.0.
1.3.2 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 which matches voltage identification on
nameplate
Multimeter with maximum sensitivity of 100 millivolts for
120 or 240 VAC transmitters
250 to 450 ohm resistor for transmitters with HART
communication
48-618 ES/EZ Modulevel Displacer Level Transmitter (Top Hat Assembly Design)

1.3.3 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 +160° F (-40° to +70° C). The operating
temperature range for the digital display is -4° to +160° F
(-20° to +70° C).
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
too equalize pressure across the device very slowly.
1.4
Mounting
The 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 4.9.
Liquid
Level
Displacer
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.

Before installing, ensure that:
There is adequate headroom for the installation of the
Modulevel head and displacer and that it has unobstructed
entry into the vessel.
Using a level, the mounting flange is horizontal within 3°.
If the adjustable hanger assembly (P/N 32-3110-001) is
used, it is cut to the required length and attached to the
displacer stem.
48-618 ES/EZ Modulevel Displacer Level Transmitter (Top Hat Assembly Design)
Note: The adjustable hanger assembly is used when the top
of the displacer and, therefore, the top of the measurement range must be positioned in the vessel more
than 5" (127 mm) below the mounting flange in the
case of models 600# or less, or more than 9.31" below
the mounting flange on models 900# or greater. The
maximum hanger cable length is 8 feet.
•
A stilling well is installed for applications where continuous
agitation is present. The stilling well must be vertically level
so as not to restrict displacer movement.
See Figure 2 for a typical stilling well installation.
•
The process temperature, pressure and specific gravity are
within the unit’s specifications for installation.
See Specifications, Section 4.8.
To install:
Use stilling well in
case of turbluent
medium
Figure 2

with Stilling Well
1. Carefully place the displacer in the vessel. Align the gasket
on the flange.
2. Align the Modulevel flange with the flanged connection on
the vessel.
3. Make sure the flange gasket is seated properly. Install flange
bolts and nuts.
4. Tighten alternating flange bolts in a star pattern.
Caution: All Modulevels are shipped from the factory with the
enclosing tube tightened and the transmitter head
set screws locked to the enclosing tube. Failure to
loosen the set screws prior to repositioning the
supply and output connections may cause the
enclosing tube to loosen, resulting in the possible
leakage of the process liquid or vapor.
Size 1/8"
Always unlock for repositioning or removal
of head assembly and always relock,
after final positioning
5. Loosen the transmitter head lock screws (socket type) and
position conduit outlet in the desired direction.
See Figure 3.
6. Retighten lock screws.
Note:

Since the transmitter head is rotatable through 360º,
it is important to make certain that the controller
locking screws are tight before making electrical
connections.
1.4.2 Installing a Chamber Type Modulevel (E63, E64, E65,
E66, E53, and E55)
The chamber type Modulevel is mounted on the side of
the vessel with either a side/side or side/bottom connection, as furnished. Figure 4 on page 5 illustrates a typical
chamber type installation.

Before installing, ensure that:
There is adequate room for the installation of the
Modulevel.
Using a level, the vessel mounting connections are level
within 3° of vertical.
The process temperature, pressure and specific gravity are
within the unit’s specifications for installation.
See Specifications, Section 4.8.
If not already done, remove the shipping strap and wire
assembly holding the displacer in place in the chamber.
This assembly must be removed through the bottom
chamber connection or drain before start-up.
To install:
1. Carefully align the Modulevel chamber process connections with the vessel connections.
2. Attach the process connections accordingly, based on the
type of connection. Appropriate gaskets and bolting will
be required if using flanged process connections.
Note: It is recommended that shut-off valves be installed in
each equalizing line to the chamber, along with a
blow-down valve (refer to Figure 4). Equalizing lines
should be sized at least as large as the connections
provided at the chamber.
3. Make sure that the chamber is vertically level within 3° in
each direction to ensure frictionless operation of the internal displacer.
Caution: All Modulevels are shipped from the factory with
the enclosing tube tightened and the transmitter
head set screws locked to the enclosing tube.
Failure to loosen the set screws prior to repositioning the supply and output connections may cause
the enclosing tube to loosen, resulting in the possible leakage of the process liquid or vapor.
4. Loosen the transmitter head lock screws (socket type) and
position conduit outlet in the desired direction. See Figure
3 on page 4.
5. Retighten lock screws.
Note: Since the transmitter head is rotatable through 360º, it

Calibrating the Analog EZ Modulevel
The Analog EZ Modulevel must be calibrated for each
unique application. It may be calibrated in service or on
a bench calibration stand. Bench calibration provides a
convenient way to set up the transmitter before going to
the tank site to complete the installation. Bench calibration, however, does not compensate for elevated process
temperatures.
For convenience during the calibration of a blind transmitter, a DC milliameter may be connected to terminals (M+)
and (M-) in the junction box, see Figure 5 on page 6.

Digital ES II Push-Button Calibration
The Digital ES II Modulevel must be calibrated for each
unique application. It may be calibrated using the pushbuttons on the PC board or using a HART communicator.
The HART hand-held communicator allows advanced
calibration.
The Digital ES II Modulevel may be calibrated in service or
on a bench calibration stand (P/N 31-6107-001) (except
units that have been calibrated for interface service. Bench
callibration cannot be performed on interface models).
Bench calibration provides a convenient way to set up the
transmitter before going to the tank site to complete the
installation. Bench calibration, however, does not compensate for elevated process temperatures and must be fine
tuned in the field.

In the case that 20 mA (100%) level cannot be established:
11. After setting the zero point, establish the liquid level as
close to the 20 mA level as possible (must be more than
50% of the total span).
12. Press ENTER to start 20 mA calibration. The ZERO LED
will light. Loop will go to 22 mA.
13. Press UP to lock in 20mA value. The ZERO LED will go
off. The SPAN LED will be on. Loop will go to 20 mA.
14. Toggle UP and DOWN until the loop signal corresponds
with the % of actual level (e.g. 80 % level should equal
(20 mA – 4 mA) x 80% + 4 mA = 16.8 mA).
15. Press ENTER to confirm the setting. The SPAN LED will
go off. Loop will stay at value chosen in step 14 above.
16. Replace cover.
Note: When calibrating for reverse action (4 mA at high level, 20
mA at low level) step 2 will be establishing high level at the
4 mA level and step 7 will be bringing the level down to the
20 mA level.
3.4.2 Push-button Bench Calibration
The Digital ES II Modulevel can be bench calibrated using

Reference Information
This section presents an overview of the operation of the Electronic Modulevel Displacer Level
Transmitter, information on troubleshooting common problems, listings of agency approvals, lists
of replacement and recommended spare parts, and detailed physical, functional, and performance
specifications.
4.1
Description
The Digital ES II and Analog EZ Modulevels are advanced, intrinsically safe or explosion proof twowire or four-wire instruments utilizing simple buoyancy principles to detect and convert liquid level
changes into a stable 4–20 mA output signal. The linkage between the level sensing element and the
output electronics provides a simple mechanical design and construction. The vertical in-line design of
the transmitter results in low instrument weight and simplifies installation. The instrument comes in
a variety of configurations and pressure ratings for varied applications.
The Digital ES II Modulevel has micro-processor based electronics with HART compatible output,
in addition to the standard 4–20 mA DC output. The Analog EZ Modulevel provides a simple
4–20 mA output.

4.2
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 23.
4.2.1 Displacer Buoyancy
The buoyancy force acting on an object is equal to the
weight of the liquid displaced by the object. As the level
changes, and more or less of the displacer is submerged in
liquid, the buoyancy force on the displacer changes. This
change is detected by the range spring from which the displacer hangs. The compression or elongation of the range
spring, in turn, causes movement of the LVDT core
mounted on the rigid stem attached to the spring.
4.2.2 LVDT
An LVDT is a linear variable differential transformer made
up of a primary winding, two secondary windings and a
special magnetic steel core. The primary winding and the
two secondary windings form an open transformer. The
secondary windings are positioned, one above each other,
opposite the primary winding. The primary winding is
powered so that when the magnetic steel core is positioned
between the primary and one or both of the secondary
windings, a current is induced in the secondary winding(s).
By comparing the currents in the two secondary windings,
the exact position of the core, and therefore the liquid
level, can be measured.
4.3
Troubleshooting
The Electronic Modulevel Displacer Level Transmitter is
designed and engineered for trouble-free operation over a
wide range of operating conditions. Common transmitter
problems are discussed in terms of their symptoms and
corrective actions as recommended.
WARNING! Explosion hazard. Do not connect or disconnect
equipment unless power has been switched off
or the area is known to be non-hazardous.
The table on the next page provides information on how
to troubleshoot transmitter-level problems.

1. Remove the dummy enclosing tube (if provided) from the
new ES II housing assembly.
2. Remove the transmitter and terminal housing covers.
3. Lower the complete ES II assembly onto the existing
enclosing tube, being careful not to bend the enclosing
tube. Make sure the housing set screws are loose so that the
assembly fits tightly to the enclosing tube nut. As you
lower the assembly, guide the PC board assembly mounting
bracket onto the enclosing tube.
4. Replace the white plastic positioner on the enclosing tube
making sure it is snug against the enclosing tube base;
then, slide the LVDT down the enclosing tube until it rests
firmly on the white plastic positioner.
5. Replace the c-ring at the top of the enclosing tube.
6. Connect the 8-pin LVDT into the socket at J1.
7. Connect the field wiring to the terminals in the terminal
housing. Check the terminal markings for +/- polarity.
8. Replace the transmitter housing cover.
9. Apply power and check for output signal.
10. Calibrate the transmitter as described in Sections 3.4 & 3.5.

Service Policy
Return Material Procedure
Owners of Magnetrol/STI 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/STI 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 Magnetrol/STI’s 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.
No claims for misapplication, labor, direct or consequential damage will be allowed.
