Introduction and Specifications
Scope of Manual
This instruction manual is a supplement to the DLC3100 and DLC3100 SIS Quick Start Guide (D104214X012) that
ships with every digital level controller. This instruction manual includes specifications, operating, and maintenance
information for FIELDVUE DLC3100 and DLC3100 SIS digital level controllers.
Notes
The DLC3100 SIS is identified by a label affixed to the terminal box cover.
Unless otherwise noted, the information in this document applies to both DLC3100 and DLC3100 SIS. However, for simplicity, the
DLC3100 model name will be used throughout.
This instruction manual supports the 475 Field Communicator with device description revision 1, used with DLC3100
instruments with firmware revision 1.0.9. You can obtain information about the process, instrument, or sensor using
Do not install, operate, or maintain a DLC3100 digital level controller without being fully trained and qualified in valve,
actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is
important to carefully read, understand, and follow all the contents of this manual, including all safety cautions and
warnings. If you have any questions regarding these instructions, contact your Emerson sales office before proceeding.
Installation, Mounting and Electrical Connections, and Initial
Configuration and Calibration using the Local User Interface
Refer to the DLC3100 and DLC3100 SIS Quick Start Guide (D104214X012) for installation and connection information,
as well as initial configuration and calibration using the local user interface. If a copy of this quick start guide is needed
contact your Emerson sales office or visit Fisher.com.

July 2019
Several operations with the DLC3100 can be performed using the Field Communicator. The digital level controller can
be configured, calibrated, or tested. Using the HART protocol, information from the field can be integrated into
control systems or be received on a single loop basis.
DLC3100 digital level controllers are designed to directly replace standard pneumatic and electro-pneumatic level
transmitters. DLC3100 digital level controllers mount on a wide variety of caged and cageless 249 level sensors. They
can also be mounted on other manufacturers’ displacer type level sensors with designed mounting kits.
CAUTION
There are many magnets used in the DLC3100 (lever assembly, push button, coupling handle). Care must be taken to avoid
having a high powered magnet in close proximity. This could cause permanent damage to the DLC3100. Potential sources
of damaging equipment include, but are not limited to: transformers, DC motors, stacking magnet assemblies.
General Guidelines for use of High Power Magnets:
Use of high power magnets in close proximity to any instrument which is operating a process should be avoided.
Regardless of the instrument model, high power magnets can affect its functionality.
249 Caged Sensors
249, 249B, 249BF, 249C, 249K and 249L sensors side-mount on the vessel with the displacer mounted inside a cage
outside the vessel.
249 Cageless Sensors
249BP, 249CP and 249P sensors top-mount on the vessel with the displacer hanging down into the vessel.
249VS sensor side-mounts on the vessel with the displacer hanging out into the vessel.
249W wafer-style sensor mounts on top of a vessel or on a customer-supplied cages.

Note
This information supplements the Electrical Connections section in the quick start guide (D104214X012) that shipped with your
instrument. If a copy of this quick start guide is needed contact your Emerson sales office or visit Fisher.com.
Test Connections
WARNING
Personal injury or property damage caused by fire or explosion may occur if this connection is attempted in an area which
contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and
atmosphere conditions permit the safe removal of the terminal box cap before proceeding.
Test connections inside the terminal box can be used to measure loop current across an internal 1 ohm resistor.
1. Remove the terminal box cap.
2. Adjust the test meter to measure mV.
3. Connect the positive lead of the test meter to the + connection and the negative lead to the TEST connection inside
the terminal box.
4. Measure Loop current as mV = mA. For example, if the meter measures 12.5 mV, it means the loop current is
12.5 mA.
5. Remove test leads and replace the terminal box cover.
Alarm Conditions
Each digital level controller continuously monitors its own performance during normal operation. This automatic
diagnostic routine is a timed series of checks repeated continuously. If diagnostics detect a failure in the electronics,
the instrument drives its output to trip alarm current either below 3.6 mA or above 21 mA, depending on the position
(High/Low) of the alarm switch.
An alarm condition occurs when the self-diagnostics detect an error that would render the process variable
measurement inaccurate, incorrect, or undefined, or a user defined threshold is violated. At this point the analog
output of the unit is driven to a defined level either above or below the nominal 4-20 mA range, based on the position
of the alarm switch. The factory default Alarm Switch setting is High.

Loop Test
Note
The DLC3100 must be put out of service during Loop Test. Place the loop into manual operation before putting device out of
service as the DLC3100 output may not be valid.
When the DLC3100 is out of service, it is locked for exclusive access by the Primary/Secondary master that put it out of service. If
the instrument reports Locked by HART or Access Restricted when you attempt to configure it, and a master of the original
priority is not available, use Force Mode on the Local User Interface menu to force the instrument mode to In Service. You will
then be able to take it out of service with your own master to make changes.
Loop Test can be used to verify the controller output, the integrity of the loop, and the operations of any recorders or
similar devices installed in the loop. To initiate a loop test, perform the following procedure:
1. Connect a reference meter to the controller. To do so, either connect the meter to the test connections inside the
terminal box (see Test Connections procedure) or connect the meter in the loop as shown in figure 8.
2. Access Loop Test via Service Tools > Maintenance > Tests > Loop Test (3-4-2-2).
3. Select OK after you set the control loop to manual. The Field Communicator displays the loop test menu.
4. Put the instrument to “Not in Service” and select analog output level: 4mA, 20mA or Other to manually input a
value between 4 and 20 milliamps.
5. Check the reference meter to verify that it reads the value that is commanded. If the readings do not match, either
the controller requires an output trim, or the meter is malfunctioning.
After completing the test procedure, the display returns to the loop test screen and allows you to choose another
output value or end the test and put instrument back in service.

Configuration and Calibration using AMS Device Manager or a
Field Communicator
Note
Refer to the DLC3100 and DLC3100 SIS Quick Start Guide (D104214X012) for configuration and calibration using the local user
interface. If a copy of this quick start guide is needed contact your Emerson sales office or visit Fisher.com.
DLC3100 has to be set to “Not In Service” during configuration and calibration which include:
DꢀDevice Setup
DꢀPV Setup
DꢀProcess Setup
DꢀCalibration
DꢀManual Setup
DꢀAlert Setup
The DLC3100 will continue to regulate the current output based on lever assembly position. The output can be at
failed current value (determine by alarm switch on the Main Electronics Board) depending on the device alerts/status.
This current output shall not be treated as actual level/interface measurement as the device is “Not In Service”.
CAUTION
The control loop must be in manual before putting DLC3100 to Not In Service.
Note
When configuring the DLC3100 using the DD, the access of DLC3100 via Local User Interface will be locked.
If a DLC3100 digital level controller ships from factory mounted on a 249 sensor, initial setup and calibration may not
be necessary. The factory enters the sensor data, couples the instrument to the sensor, and calibrates the instrument
and sensor combination.

Instruction Manual
D104213X012
Note
If the digital level controller mounted on the sensor is received with the displacer blocked, or if the displacer is not connected, the
instrument will be coupled to the torque tube assembly and the lever assembly unlocked. To place the unit in service, if the
displacer is blocked, remove the rod and block at each end of the displacer and check the instrument calibration. (If the “factory
cal” option was ordered, the instrument will be pre-compensated to the process conditions provided on the requisition, and may
not appear to be calibrated if checked against room temperature with 0% and 100% water level inputs). If the displacer is not
connected, hang the displacer on the torque tube.
If the digital level controller mounted on the torque tube arm and the displacer is not blocked when received (such as in skid
mounted systems), the instrument will not be coupled to the torque tube assembly, and the lever assembly will be locked. To
place the unit in service, couple the instrument to the sensor and unlock the lever assembly.
When the 249 assembly is properly connected and coupled to the digital level controller, establish the zero process condition and
perform the Trim Zero procedure. The torque tube rate should not need to be recalibrated.
To review the configuration data entered by the factory, connect the instrument to a 24 VDC power supply as shown in
review the data under Manual Setup and Alert Setup. If application data has been changed since the instrument was
factory-configured, refer to the Manual Setup section for instructions on modifying configuration data.

Configuration Advice
Force Mode
Local User Interface Menu > Force Mode
When the DLC3100 is out of service, it is locked for exclusive access by the Primary/Secondary master that put it out of
service. The same master must be used to put the instrument back in service; another master will not be able to
change anything on the device and the LCD will return a “Locked by HART” message, unless you run Force Mode.
Select Force Mode to force the instrument mode to In Service if the original master is not available.
Note
Make sure no outstanding tasks are on-going in the device, including configuration and calibration, before forcing the DLC3100 In
Service
Write Protection
To setup and calibrate the instrument, write protection must be set to disable.
Level Offset
Level Offset is the value DLC3100 reports when the process level is at the bottom of the displacer. Adding a level offset
permits the process variable value in engineering units to be reported with respect to a reference point other than the
bottom of the displacer. Examples include: bottom of the process vessel, the process set point, or sea level. Set Level
Offset is only available in Level or Interface measurement mode. Follow the prompts on the Field Communicator to
enter the offset value (2-3-2-1-6).
Level Offset will affect URV/LRV, PV Hi/Lo, PV HiHi/LoLo alerts. Changing PV alert points assumes you have already
considered the affect of Level Offset on the alert points. This parameter should be cleared to zero before running
Device Setup.

Initial Setup
Initial Setup consists of the following:
DꢀDevice Setup
DꢀPV Setup
DꢀProcess Setup
All three setup procedures must be completed when configuring the DLC3100 in order for the device to function
properly.
Initial Setup directs you through initialization of configuration data needed for proper operation. When the instrument
comes out of the box, the default dimensions are set for the most common Fisher 249 construction. If any data is
unknown, it is generally safe to accept the defaults. The mounting position - left or right of displacer - is important for
correct interpretation of positive motion. Use Manual Setup to locate and modify individual parameters when they
need to be changed. Refer to the Initial Setup section below for DLC3100 configuration.
Notes
The DLC3100 has to be “Not In Service” when carrying out Initial Setup. Place the loop into manual operation before putting
device out of service as the output will not be valid.
When the DLC3100 is out of service, it is locked for exclusive access by the Primary/Secondary master that put it out of service. If
the instrument reports Locked by HART or Access Restricted when you attempt to configure it, and a master of the original
priority is not available, use Force Mode on the Local User Interface menu to force the instrument mode to In Service. You will
then be able to take it out of service with your own master to make changes.
Guided setup is available to aid initial setup. Follow the prompts to enter information required by the setup. Most of
the information is available from the sensor nameplate.

PV Setup consists of the following:
DꢀAnalog Output Action (Direct or Reverse)
DꢀLevel Offset
DꢀMeasurement Range (Lower Range Value and Upper Range Value)
Note
For interface applications, if the 249 is not installed on a vessel, or if the cage can be isolated, calibrate the instrument with
weights, water, or other standard test fluid, in level mode. After calibrating in level mode, the instrument can be switched to
interface mode, then enter the actual process fluid specific gravity and range values, follow with Trim Zero.
Table 12. Application Information
Measurement Application
Description
The default process variable units are set to the same units chosen for displacer length. When level
offset is changed, range values will be initialized based on level offset and displacer length. The default
upper range value is set to equal to displacer length and the default lower range value is set to zero when
the level offset is 0.
Level, Interface
The default process variable units are set to “SGU” (Specific Gravity Units). The default upper range value
is set to “1.0” and the default lower range value is set to ”0.1”.
Density
When a DLC3100 with analog output is set for direct action the loop current will increase as the fluid level increases.
Upper Range Value is the process variable values at 20 mA and Lower Range Value is the process variable values at
4 mA.
Choosing Reverse action will swap the default values of the upper and lower range values. The loop current will
decrease as the fluid level increases. Upper Range Value is the process variable values at 4 mA and Lower Range Value
is the process variable values at 20 mA.
Once PV Setup is completed configure the process information using the Process Setup procedures.

process fluid type, and enter the temperature/density table. The DLC3100 will use the best matched compensated
density value from the pre-loaded fluid type tables in DLC3100 for level measurement based on the actual process
temperature. If Custom Fluid is selected, input Temperature/Density values to custom fluid table. For level
measurement applications, only the lower fluid table is required. For interface measurement applications, both upper
fluid and lower fluid tables are required. Neither table is used for density applications.
Note
A minimum of two pairs of temperature/density values must be entered to the table. The temperatures entered must be in
ascending order.

Two-Points Calibration is usually the most accurate method for calibrating the sensor. It uses independent
observations of two valid process conditions, together with the hardware dimensional data and specific gravity
information, to compute the effective torque rate of the sensor. The two data points can be separated by any span
between a minimum of 5% to 100%, as long as they remain on the displacer. Within this range, the calibration accuracy
will generally increase as the data point separation gets larger. Accuracy is also improved by running the procedure at
process temperature, as the temperature effect on torque rate will be captured. (It is possible to use theoretical data
to pre-compensate the measured torque rate for a target process condition when the calibration must be run at
ambient conditions).

Weight Calibration may be used on the bench or with a calibration jig that can apply a mechanical force to the driver
rod to simulate displacer buoyancy changes. It allows the instrument and sensor to be calibrated using equivalent
weights or force inputs instead of using the actual displacer buoyancy changes. If the displacer information has been
entered prior to beginning the procedure, the instrument will be able to compute reasonable weight value
suggestions for the calibration. The weight values suggested during the weight calibration aim to achieve maximum
torque tube rotation for better accuracy. It does not necessary mean the weight at 0% or 100%. The only preliminary
data essential for the correct calibration of the torque rate is the length of the driver rod being used for the calibration.
Weight equivalent to the net displacer weight at two valid process conditions must be available. The sensor must have
been sized properly for the expected service, so that the chosen process conditions are in the free motion linear range
of the sensor.

Trim Zero computes the value of the input angle
required to align the digital Primary Variable with the
user’s observation of the process, and corrects the
stored input zero reference, assuming that the
calibration gain is accurate.
Gain Trim trims the torque rate value to align the
digital Primary Variable with the user’s observation.
This calibration assumes that sensor zero is already
accurate and only a gain error exists. Actual process
condition must be nonzero and able to be measured
independently. Configuration data must contain
density of calibration fluid(s), displacer volume, and
driver rod length.

Torque Rate Gain allows you to input the torque rate.

Accuracy Considerations
Effect of Proportional Band
If a DLC3100 with level sensor is operating at low Proportional Band [PB = 100% times (full span torque tube rotation) /
(4.4 degrees)], there will be a degradation factor of about (100%)/(PB%) on the device accuracy specifications.
Note
This formula is most correct for linearity errors that are relatively steep‐ sided. If the linearity error curve shape is simple with
relatively gradual slope, the net effect of reducing span may be less. Instruments such as the DLC3100, that use a compensation
technique to reduce the residual mechanical or electrical non‐ linearity, will generally have a complex shape for the net‐ error curve.
If this is too much degradation, an improvement of 2.0 can be obtained by using a thin‐ wall torque tube. Additional
gain can be achieved by increasing the displacer diameter. Available clearance inside the cage, and the need to keep
the net displacer weight at the highest and lowest process conditions within the usable range of the torque tube/driver
rod combination, place practical limits on how much the sizing can be adjusted.
With an overweight displacer, the calibration process becomes more difficult as the zero buoyancy condition will occur
with the linkage driven hard into a travel stop. In interface measurement application, it is recommended to calibrate
with actual process fluids (upper and lower fluids), or set the application to level and use water to calibrate the
DLC3100.
Density Variations in Interface Applications
A high sensitivity to errors in the knowledge of fluid density can develop in some interface applications.
For example: Suppose the whole input span is represented by an effective change in SG of 0.18. Then a change in the
actual SG of the upper fluid from 0.8 to 0.81 could cause a measurement error of 5.6% of span at the lowest interface
level. The sensitivity to the knowledge of a fluid density is maximum at the process condition where that fluid covers
all the displacer, zero at the opposite extreme process condition, and varies linearly between those points.
If the fluid density changes are batch‐ related or very gradual, it may be practical to keep track of the SG of the fluid and
periodically reconfigure the DLC3100 density setting to match the actual process condition. Frequent automatic
updates to this variable are not advisable as the NVM location where it is stored has a write limit. If changes are only a
function of temperature, the characteristic of the fluid can be loaded once in the density table, and an RTD connected
to measure the process temperature and drive the temperature compensation table. If temperature is not the driving
influence, the best that can be done is to calibrate for the widest potential differential SG. This will keep the variations
as small a percentage of calibrated span as possible. Then calculate an alarm threshold that will prevent vessel over‐ or
under‐ flow at the worst-case error.

D104213X012
Extreme Process Temperatures
For applications that will run at extreme temperatures, the effect of process temperature on the torque tube must be
considered. Best results are obtained by running the torque tube calibration at actual process temperature. However,
the decrease in spring rate with temperature can be simulated at room temperature by increasing the load on the
torque tube during room‐ temperature calibration. This will produce the same deflection that would occur at actual
process conditions. This compensation is theoretical and not perfect, but is still an improvement over ambient
calibration with no attempt at compensation.
Note
For additional information, refer to the Simulation of Process Conditions for Calibration of Fisher Level Controllers and
Temperature Compensation
AMS Configure > Manual Setup > Process
Field Communicator Configure > Manual Setup > Process (2-3-4)
If the process temperature departs significantly from calibration temperature, temperature compensation can be
enabled. By selecting Process Temperature Input to either RTD or Manual, the temperature compensation will be
enabled. DLC3100 digital level controller will use the correct fluid density from the default fluid table (depending on
Custom Table must have ascending temperature inputs.

You can also correct the temperature effect by applying a correction factor to the torque tube rate. Interpolate the
correction factor from the material‐ specific tables of theoretical normalized modulus of rigidity versus temperature,
as described in Simulation of Process Conditions for Calibration of Fisher Level Controllers and Transmitters
(D103066X012). Multiply the measured torque tube rate (editable in Configure > Calibration > Trim Current
Calibration > Torque Tube Gain) by the correction factor and enter the new value. This approach allows a better
approximation of the actual torque tube behavior at process conditions when calibration cannot be carried out at
process temperature.

Maintenance and Troubleshooting
The DLC3100 digital level controller features a modular design for easy maintenance. If there is a malfunction, check
for an external cause before performing the diagnostics describe in this section.
Sensor parts are subject to normal wear and must be inspected and replaced as necessary. For sensor maintenance
information, refer to appropriate sensor instruction manual.
WARNING
To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any maintenance
operations.
Personal injury or property damage due to sudden release of pressure, contact with hazardous fluid, fire, or explosion can
be caused by puncturing, heating, or repairing a displacer that is retaining process pressure or fluid. This danger may not
be readily apparent when disassembling the sensor or removing the displacer. Before disassembling the sensor or
removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
CAUTION
When replacing components, use only components specified by the factory. Always use proper component replacement
techniques, as presented in this manual. Improper techniques or component selection may invalidate the approvals and

1. Loosen the set screw (key 34) in the terminal box cover assembly (key 7) so that the cover can be unscrewed from
the terminal box.
2. After removing the cover, note the location of field wiring connections and disconnect the field wiring from the
wiring terminals.
3. As shown in figure 11, locate the access handle on the bottom of the transducer housing. Push the handle button
and slide toward the front of the DLC3100 (locked position), to expose the access hole. Be sure the locking handle
drops into the detent.

Note
If the access handle will not slide, the sensor linkage is most likely in an extreme position. When the lever assembly is at a hard stop
inside the housing, the locking pin on the access door may not be able to engage the mating slot in the lever assembly. This
condition can occur if the displacer has been removed, if the sensor is lying on its side, or if the instrument had been coupled to the
sensor while the displacer was not connected. To correct this condition, manipulate the sensor linkage to bring the lever assembly
to within approximately 4 degrees of the neutral position before attempting to slide the handle. A probe inserted through the top
vent of the 249 head may be required to deflect the driver rod to a position where the lever assembly is free.

5. Loosen and remove the hex nuts (key 15) from the mounting studs (key 14).
CAUTION
Tilting the instrument when pulling it off of the sensor torque tube can cause the torque tube shaft to bend. To prevent
damage to the torque tube shaft, ensure that the digital level controller is level when pulling it off the sensor torque tube.
6. Remove the digital level controller as follows:
DꢀFor standard temperature applications carefully pull the digital level controller straight off the sensor torque
tube.
DꢀFor high temperature applications carefully pull the digital level controller straight off the sensor torque tube

Appendix A
Principle of Operation
HART Communication
The HART (Highway Addressable Remote Transducer) protocol gives field devices the capability of communicating
instrument and process data digitally. This digital communication occurs over the same two‐wire loop that provides
the 4-20 mA process control signal, without disrupting the process signal. In this way, the analog process signal, with
its faster update rate, can be used for control. At the same time, the HART protocol allows access to digital diagnostic,
maintenance, and additional process data. The protocol provides total system integration via a host device.
The HART protocol uses the frequency shift keying (FSK) technique based on the Bell 202 communication standard. By
superimposing a frequency signal over the 4-20 mA current, digital communication is attained. Two individual
frequencies of 1200 and 2200 Hz are superimposed as a sinewave over the 4-20 mA current loop. These frequencies
to the 4-20 mA signal. Thus, true simultaneous communication is achieved without interrupting the process signal.

The HART protocol allows the capability of multidropping, networking several devices to a single communications line.
This process is well suited for monitoring remote applications such as pipelines, custody transfer sites, and tank farms.
Multidrop Communication
“Multidropping” refers to the connection of several digital level controllers or transmitters to a single communications
transmission line. Communication between the host and the field instruments takes place digitally with the analog
output of the instruments deactivated. With the HART communications protocol, up to 15 field instruments can be
connected on a single twisted pair of wires or over leased phone lines. Multidrop installations are not recommended
where intrinsic safety is a requirement.
The application of a multidrop installation requires consideration of the update rate necessary from each instrument,
the combination of instrument models, and the length of the transmission line. Communication with the field
instruments can be accomplished with commercially available Bell 202 modems and a host implementing the HART
protocol. Each instrument is identified by a unique address (1-15) and responds to the commands defined in the HART
protocol.

The Field Communicator can test, configure, and format a multidropped DLC3100 digital level controller in the same
way as in a standard point‐to‐point installation, provided that it has been configured to scan for multiple polling
addresses.
Note
DLC3100 digital level controllers are set to address 0 at the factory, allowing them to operate in the standard point‐to‐point
manner with a 4-20 mA output signal. To activate multidrop communication, the address must be changed to a number between
1 and 15. This change deactivates the 4-20 mA analog output, sending it to 4 mA. The failure mode current also is disabled.
Digital Level Controller Operation
The DLC3100 digital level controller is a loop‐powered instrument that measure changes in liquid level, level of an
interface between two liquids, or density of a liquid. Changes in the buoyancy of a displacer suspended in a vessel vary
the load on a torque tube. The displacer and torque tube assembly constitute the primary mechanical sensor. The
angular deflection of the torque tube is measured by the instrument transducer, which consists of a magnet system
moving over a Hall effect device. A liquid crystal display (LCD) meter can display the analog output or process variable
(level, interface level, or density) in units or percent range.
The instrument uses a microcontroller and associated electronic circuitry to measure the process variable, provide a
meter, the processor module, the transducer board, and the terminal board. The processor module contains the
microprocessor, the analog‐to‐digital (A/D) converters, loop interface, signal conditioning, the digital‐to‐analog (D/A)
output, power supply and interfaces to other boards.

This change is transferred to the torque tube assembly. As the measured fluid changes, the torque tube assembly
rotates up to 4.4 degrees for a 249 sensor, varying the digital level controller output between 4 and 20 mA.

The rotary motion of the torque tube is transferred to the digital level controller lever assembly. The rotary motion
moves a magnet attached to the lever assembly, changing the magnetic field that is sensed by the Hall effect sensor.
The sensor converts the magnetic field signal to an electronic signal.
The microcontroller accepts the electronic signal, which is ambient‐temperature‐compensated and linearized. The
microcontroller can also actively compensate for changes in liquid specific gravity due to changes in process
temperature based on an input via HART protocol or via an optional RTD, if it is connected. The D/A output circuit
accepts the microcontroller output and provides a 4 to 20 mA current output signal.
During normal operation, when the input is between the lower and upper range values, the digital level controller
the lower and upper range values, the output will continue to be proportional to the input until the output reaches
either 3.8 or 20.5 mA. At this time the output is considered saturated and will remain at this value until the input
returns to the normal operating range. However, should an alarm occur, the output is driven to either > 21 mA or < 3.6
mA, depending on the Alarm High/Low switch setting.
