Description
DLC3010 Digital Level Controllers
DLC3010 digital level controllers (figure 1‐1) are used with level sensors to measure liquid level, the level of interface
between two liquids, or liquid specific gravity (density). Changes in level or specific gravity exert a buoyant force on a
displacer, which rotates the torque tube shaft. This rotary motion is applied to the digital level controller, transformed

to an electrical signal and digitized. The digital signal is compensated and processed per user configuration
requirements, and converted back to a 4‐20 mA analog electrical signal. The resulting current output signal is sent to
an indicating or final control element.
Figure 1‐1. FIELDVUE DLC3010 Digital Level Controller
W7977-1
DLC3010 digital level controllers are communicating, microprocessor‐based level, interface, or density sensing
instruments. In addition to the normal function of providing a 4‐20 milliampere current signal, DLC3010 digital level
controllers, using the HART communications protocol, give easy access to information critical to process operation.
You can gain information from the process, the instrument, or the sensor using a Field Communicator with device
descriptions (DDs) compatible with DLC3010 digital level controllers. The Field Communicator may be connected at
the digital level controller or at a field junction box.
Using the Field Communicator, you can perform several operations with the DLC3010 digital level controller. You can
interrogate, configure, calibrate, or test the digital level controller. Using the HART protocol, information from the
field can be integrated into control systems or be received on a single loop basis.
DLC3010 digital level controllers are designed to directly replace standard pneumatic and electro‐pneumatic level
transmitters. DLC3010 digital level controllers mount on a wide variety of caged and cageless 249 level sensors. They
mount on other manufacturers' displacer type level sensors through the use of mounting adaptors.
249 Caged Sensors (see table 1‐6)
249, 249B, 249BF, 249C, 249K, and 249L sensors side‐mount on the vessel with the displacer mounted inside a cage
outside the vessel. (The 249BF caged sensor is available only in Europe, Middle East, and Africa.)
249 Cageless Sensors (see table 1‐7)
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 cage.
Specifications
Specifications for the DLC3010 digital level controller are shown in table 1‐1. Specifications for the 249 sensor are
shown in table 1‐3. Specifications for the Field Communicator can be found in the Product Manual for the Field
Communicator.

Level, Interface, or Density: Rotary motion of torque
tube shaft proportional to changes in liquid level,
interface level, or density that change the buoyancy
of a displacer.
NOTE: At full design span, reference conditions.
1. To lever assembly rotation inputs.
Process Temperature: Interface for 2‐ or 3‐wire 100
ohm platinum RTD for sensing process temperature,
or optional user‐entered target temperature to
permit compensating for changes in specific gravity
At effective proportional band (PB)<100%, linearity,
dead band, and repeatability are derated by the factor
(100%/PB)
Output Signal
Operating Influences
Analog: 4‐20 milliamperes DC (direct
action—increasing level, interface, or density
increases output; or reverse action—increasing
level, interface, or density decreases output)
Power Supply Effect: Output changes <±0.2% of full
scale when supply varies between min. and max
voltage specifications.
Transient Voltage Protection: The loop terminals are
protected by a transient voltage suppressor. The
specifications are as follows:
High saturation: 20.5 mA
Low saturation: 3.8 mA
High alarm: 22.5 mA
Low Alarm: 3.7 mA

HART impedance requirements must be met to
enable communication. Total shunt impedance
across the master device connections (excluding the
master and transmitter impedance) must be between
230 and 1100 ohms. The transmitter HART receive
impedance is defined as:
Rx: 42K ohms and
Cx: 14 nF
Ambient Temperature: The combined temperature
effect on zero and span without the 249 sensor is less
than 0.03% of full scale per degree Kelvin over the
operating range -40 to 80C (-40 to 176F)
Process Temperature: The torque rate is affected by
the process temperature (see figure 1‐2). The process
density may also be affected by the process
temperature.
Note that in point‐to‐point configuration, analog and
digital signalling are available. The instrument may be
queried digitally for information, or placed in Burst
mode to regularly transmit unsolicited process
information digitally. In multi‐drop mode, the output
current is fixed at 4 mA, and only digital
communication is available.
Process Density: The sensitivity to error in knowledge
of process density is proportional to the differential
density of the calibration. If the differential specific
gravity is 0.2, an error of 0.02 specific gravity units in
knowledge of a process fluid density represents 10%
of span.

in3), most others have standard volume of ∼1640 cm3
(100 in3).
Diagnostics
Output loop current diagnostic.
LCD meter diagnostic.
Spot specific gravity measurement in level mode: used
to update specific gravity parameter to improve
process measurement
Digital signal‐tracing capability: by review of
“troubleshooting variables”, and
Basic trending capability for PV, TV and SV.
Operating at 5% proportional band will degrade
accuracy by a factor of 20. Using a thin wall torque
tube, or doubling the displacer volume will each
roughly double the effective proportional band.
When proportional band of the system drops below
50%, changing displacer or torque tube should be
considered if high accuracy is a requirement.

instruments factory‐mounted on 249 sensor.
Factory Calibration: available for instruments
factory‐mounted on 249 sensor, when application,
process temperature and density(s) are supplied.
Device is compatible with user‐specified remote
indicator.
Mounting Positions
Digital level controllers can be mounted right‐ or
left‐of‐displacer, as shown in figure 2‐5.
Instrument orientation is normally with the coupling
access door at the bottom, to provide proper
drainage of lever chamber and terminal
compartment, and to limit gravitational effect on the
lever assembly. If alternate drainage is provided by
user, and a small performance loss is acceptable, the
instrument could be mounted in 90 degree rotational
increments around the pilot shaft axis. The LCD meter
may be rotated in 90 degree increments to
accommodate this.

Installation
September 2013
Section 2 Installation2-2This section contains digital level controller installation information including an installation flowchart (figure 2‐1),
mounting and electrical installation information, and a discussion of failure mode jumpers.
Configuration: On the Bench or in the Loop
Configure the digital level controller before or after installation. It may be useful to configure the instrument on the
bench before installation to ensure proper operation, and to familiarize yourself with its functionality.
Protecting the Coupling and Flexures
CAUTION
Damage to flexures and other parts can cause measurement errors. Observe the following steps before moving the sensor
and controller.
Lever Lock
The lever lock is built in to the coupling access door. When the door is open, it positions the lever in the neutral travel
position for coupling. In some cases, this function is used to protect the lever assembly from violent motion during
shipment.
A DLC3010 controller will have one of the following mechanical configurations when received:
1. A fully assembled and coupled caged‐displacer system shipped with the displacer or driver rod blocked within the
operating range by mechanical means. In this case, the access handle (figure 2‐4) will be in the unlocked position.
Remove the displacer‐blocking hardware before calibration. (See the appropriate sensor instruction manual). The
coupling should be intact.
CAUTION
When shipping an instrument mounted on a sensor, if the lever assembly is coupled to the linkage, and the linkage is
constrained by the displacer blocks, use of the lever lock may result in damage to bellows joints or flexure.
2. If the displacer cannot be blocked because of cage configuration or other concerns, the transmitter is uncoupled
from the torque tube by loosening the coupling nut, and the access handle will be in the locked position. Before
placing such a configuration into service, perform the Coupling procedure found on page 42.
3. For a cageless system where the displacer is not connected to the torque tube during shipping, the torque tube
itself stabilizes the coupled lever position by resting against a physical stop in the sensor. The access handle will be
in the unlocked position. Mount the sensor and hang the displacer. The coupling should be intact.

4. If the controller was shipped alone, the access handle will be in the locked position. All of the Mounting, Coupling
and Calibration procedures must be performed.
The access handle includes a retaining set screw, as shown in figures 2‐4 and 2‐6. The screw is driven in to contact the
spring plate in the handle assembly before shipping. It secures the handle in the desired position during shipping and
operation. To open or close the access door, this set screw must be backed out so that its top is flush with the handle
surface.
Mounting
WARNING
To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation
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.

Mounting the 249 Sensor
The 249 sensor is mounted using one of two methods, depending on the specific type of sensor. If the sensor has a
caged displacer, it typically mounts on the side of the vessel as shown in figure 2‐2. If the sensor has a cageless
displacer, the sensor mounts on the side or top of the vessel as shown in figure 2‐3.
The DLC3010 digital level controller is typically shipped attached to the sensor. If ordered separately, it may be
convenient to mount the digital level controller to the sensor and perform the initial setup and calibration before
installing the sensor on the vessel.
Note
Caged sensors have a rod and block installed on each end of the displacer to protect the displacer in shipping. Remove these parts
before installing the sensor to allow the displacer to function properly.

Note
If alternate drainage is provided by the user, and a small performance loss is acceptable, the instrument could be mounted in 90
degree rotational increments around the pilot shaft axis. The LCD meter may be rotated in 90 degree increments to accommodate
this.
The digital level controller and torque tube arm are attached to the sensor either to the left or right of the displacer, as
shown in figure 2‐5. This can be changed in the field on the 249 sensors (refer to the appropriate sensor instruction
manual). Changing the mounting also changes the effective action, because the torque tube rotation for increasing
level, (looking at the protruding shaft), is clockwise when the unit is mounted to the right of the displacer and counter‐
clockwise when the unit is mounted to the left of the displacer.
All caged 249 sensors have a rotatable head. That is, the digital level controller can be positioned at any of eight
alternate positions around the cage as indicated by the position numbers 1 through 8 in figure 2‐5. To rotate the head,
remove the head flange bolts and nuts and position the head as desired.

1. If the set‐screw in the access handle (figure 2‐6) is driven against the spring plate, back it out until the head is flush
with the outer surface of the handle, using a 2 mm hex key. Slide the access handle to the locked position to expose
the access hole. Press on the back of the handle as shown in figure 2‐4 then slide the handle toward the front of the
unit. Be sure the locking handle drops into the detent.

SET‐SCREW
2. Using a 10 mm deep well socket inserted through the access hole, loosen the shaft clamp (figure 2‐4). This clamp
will be re‐tightened in the Coupling portion of the Initial Setup section.
3. Remove the hex nuts from the mounting studs. Do not remove the adapter ring.
CAUTION
Measurement errors can occur if the torque tube assembly is bent or misaligned during installation.
4. Position the digital level controller so the access hole is on the bottom of the instrument.
5. Carefully slide the mounting studs into the sensor mounting holes until the digital level controller is snug against
the sensor.
6. Reinstall the hex nuts on the mounting studs and tighten the hex nuts to 10 Nm (88.5 lbfin).
Mounting the Digital Level Controller for High Temperature Applications
Refer to figure 2‐8 for parts identification except where otherwise indicated.
The digital level controller requires an insulator assembly when temperatures exceed the limits shown in figure 2‐7.
A torque tube shaft extension is required for a 249 sensor when using an insulator assembly.
CAUTION
Measurement errors can occur if the torque tube assembly is bent or misaligned during installation.

Electrical Connections
WARNING
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous area, ingress protection and
temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage
from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or
explosion.
Proper electrical installation is necessary to prevent errors due to electrical noise. A resistance between 230 and 1100
ohms must be present in the loop for communication with a Field Communicator. Refer to figure 2‐9 for current loop
connections.

Power Supply
To communicate with the digital level controller, you need a 17.75 volt DC minimum power supply. The power
supplied to the transmitter terminals is determined by the available supply voltage minus the product of the total loop
resistance and the loop current. The available supply voltage should not drop below the lift‐off voltage. (The lift‐off
voltage is the minimum “available supply voltage” required for a given total loop resistance). Refer to figure 2‐10 to

determine the required lift‐off voltage. If you know your total loop resistance you can determine the lift‐off voltage. If
you know the available supply voltage, you can determine the maximum allowable loop resistance.

LIFT‐OFF SUPPLY VOLTAGE (VDC)
If the power supply voltage drops below the lift‐off voltage while the transmitter is being configured, the transmitter
may output incorrect information.
The DC power supply should provide power with less than 2% ripple. The total resistance load is the sum of the
resistance of the signal leads and the load resistance of any controller, indicator, or related pieces of equipment in the
loop. Note that the resistance of intrinsic safety barriers, if used, must be included.
Field Wiring
Note
For intrinsically safe applications, refer to the instructions supplied by the barrier manufacturer.
WARNING
To avoid personal injury or property damage caused by fire or explosion, remove power to the instrument before removing
the digital level controller cover in an area which contains a potentially explosive atmosphere or has been classified as
hazardous.
All power to the digital level controller is supplied over the signal wiring. Signal wiring need not be shielded, but use
twisted pairs for best results. Do not run unshielded signal wiring in conduit or open trays with power wiring, or near
heavy electrical equipment. If the digital controller is in an explosive atmosphere, do not remove the digital level
controller covers when the circuit is alive, unless in an intrinsically safe installation. Avoid contact with leads and
terminals. To power the digital level controller, connect the positive power lead to the + terminal and the negative
power lead to the - terminal as shown in figure 2‐11.

CAUTION
Do not apply loop power across the T and + terminals. This can destroy the 1 Ohm sense resistor in the terminal box. Do not
apply loop power across the Rs and — terminals. This can destroy the 50 Ohm sense resistor in the electronics module.
When wiring to screw terminals, the use of crimped lugs is recommended. Tighten the terminal screws to ensure that
good contact is made. No additional power wiring is required. All digital level controller covers must be fully engaged
to meet explosion proof requirements. For ATEX approved units, the terminal box cover set screw must engage one of
the recesses in the terminal box beneath the terminal box cover.
Grounding
WARNING
Personal injury or property damage can result from fire or explosion caused by the discharge of static electricity when
flammable or hazardous gases are present. Connect a 14 AWG (2.1 mm2) ground strap between the digital level controller
and earth ground when flammable or hazardous gases are present. Refer to national and local codes and standards for
grounding requirements.
The digital level controller will operate with the current signal loop either floating or grounded. However, the extra
noise in floating systems affects many types of readout devices. If the signal appears noisy or erratic, grounding the
current signal loop at a single point may solve the problem. The best place to ground the loop is at the negative
terminal of the power supply. As an alternative, ground either side of the readout device. Do not ground the current
signal loop at more than one point.
Shielded Wire
Recommended grounding techniques for shielded wire usually call for a single grounding point for the shield. You can
either connect the shield at the power supply or to the grounding terminals, either internal or external, at the
instrument terminal box shown in figure 2‐11.

Power/Current Loop Connections
Use ordinary copper wire of sufficient size to ensure that the voltage across the digital level controller terminals does
not go below 12.0 volts DC. Connect the current signal leads as shown in figure 2‐9. After making connections,
recheck the polarity and correctness of connections, then turn the power on.
RTD Connections
An RTD that senses process temperatures may be connected to the digital level controller. This permits the instrument
to automatically make specific gravity corrections for temperature changes. For best results, locate the RTD as close to
the displacer as practical. For optimum EMC performance, use shielded wire no longer than 3 meters (9.8 feet) to
connect the RTD. Connect only one end of the shield. Connect the shield to either the internal ground connection in
the instrument terminal box or to the RTD thermowell. Wire the RTD to the digital level controller as follows (refer to
figure 2‐11):
Two‐Wire RTD Connections
1. Connect a jumper wire between the RS and R1 terminals in the terminal box.
2. Connect the RTD to the R1 and R2 terminals.
Three‐Wire RTD Connections
1. Connect the 2 wires which are connected to the same end of the RTD to the RS and R1 terminals in the terminal
box. Usually these wires are the same color.
2. Connect the third wire to terminal R2. (The resistance measured between this wire and either wire connected to
terminal RS or R1 should read an equivalent resistance for the existing ambient temperature. Refer to the RTD
manufacturer's temperature to resistance conversion table.) Usually this wire is a different color from the wires
connected to the RS and R1 terminals.
Communication 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.
The Field Communicator interfaces with digital level controller from any wiring termination point in the 4–20 mA loop
(except across the power supply). If you choose to connect the HART communicating device directly to the
instrument, attach the device to the loop + and - terminals inside the terminal box to provide local communications
with the instrument.
Test Connections
WARNING
Personal injury or property damage caused by fire or explosion may occur if the following procedure 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 a range of 0.001 to 0.1 volts.
3. Connect the positive lead of the test meter to the + connection and the negative lead to the T connection inside the
terminal box.
4. Measure Loop current as:
Voltage (on test meter) 1000 = milliamps
example:
Test meter Voltage X 1000 = Loop Milliamps
0.004 X1000 = 4.0 milliamperes
0.020 X 1000 = 20.0 milliamperes
5. Remove test leads and replace the terminal box cover.
Multichannel Installations
You can connect several instruments to a single master power supply as shown in figure 2‐12. In this case, the system
may be grounded only at the negative power supply terminal. In multichannel installations where several instruments
depend on one power supply, and the loss of all instruments would cause operational problems, consider an
uninterruptible power supply or a back‐up battery. The diodes shown in figure 2‐12 prevent unwanted charging or
discharging of the back‐up battery. If several loops are connected in parallel, make sure the net loop impedance does
not reach levels that would prevent communication.

Note that to provide a 4‐20 mA analog output signal, the DLC3010 must use HART polling address 0. Therefore, if a
multichannel installation is used with all transmitters in 4‐20 mA output mode, some means must be provided to
isolate an individual transmitter for configuration or diagnostic purposes. A multichannel installation is most useful if
the instruments are also in multi‐drop mode and all signaling is done by digital polling.

Alarm Jumper
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 either below 3.70 mA or above 22.5 mA, depending on the position (HI/LO) of the
alarm jumper.
An alarm condition occurs when the digital level controller 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 jumper.
On encapsulated electronics 14B5483X042 and earlier, if the jumper is missing, the alarm is indeterminate, but usually
behaves as a FAIL LOW selection. On encapsulated electronics 14B5483X052 and later, the behavior will default to
FAIL HIGH when the jumper is missing.
Alarm Jumper Locations
Without a meter installed
The alarm jumper is located on the front side of the electronics module on the electronics side of the digital level
controller housing, and is labeled FAIL MODE.
With a meter installed
The alarm jumper is located on the LCD faceplate on the electronics module side of the digital level controller housing,
and is labeled FAIL MODE.
Changing Jumper Position
WARNING
Personal injury or property damage caused by fire or explosion may occur if the following procedure 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 instrument cover before proceeding.
Use the following procedure to change the position of the alarm jumper:
1. If the digital level controller is installed, set the loop to manual.
2. Remove the housing cover on the electronics side. Do not remove the cover in explosive atmospheres when the
circuit is alive.
3. Set the jumper to the desired position.
4. Replace the cover. All covers must be fully engaged to meet explosion proof requirements. For ATEX approved
units, the set screw on the transducer housing must engage one of the recesses in the cover.

2. Access Loop Test.
3. Select OK after you set the control loop to manual.
The Field Communicator displays the loop test menu.
4. Select a discreet milliamp level for the controller to output. At the “Choose analog output” prompt, select 4 mA,
20 mA, or Other to manually input a value between 4 and 20 milliamps.
5. Check the reference meter to verify that it reads the value you commanded the controller to output. 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.

Commissioning the Digital Level Controller for use with the HART Tri‐Loop
To prepare the digital level controller for use with a 333 HART Tri‐Loop, you must configure the digital level controller
to burst mode, and select the dynamic variables to burst. In burst mode, the digital level controller provides digital
information to the HART Tri‐Loop HART‐to‐Analog Signal Converter. The HART Tri‐Loop converts the digital
information to a 4‐20 mA analog signal. The HART Tri‐Loop divides the signal into separate 4‐20 mA loops for the
primary (PV), secondary (SV), tertiary (TV), and quaternary (QV) variables. Depending upon the burst option selected,
the digital level controller will burst the variables as shown in table 2‐5.
The DLC3010 status words are available in the HART Burst messages. However, the Tri‐Loop cannot be configured to
monitor them directly.
To commission a DLC3010 digital level controller for use with a HART Tri‐Loop, perform the following procedure.

Section 4 Configuration and Calibration 4-4Initial Setup
If a DLC3010 digital level controller ships from the factory mounted on a 249 sensor, initial setup and calibration is not
necessary. The factory enters the sensor data, couples the instrument to the sensor, and calibrates the instrument and
sensor combination.
Note
If you received the digital level controller mounted on the sensor with the displacer blocked, or if the displacer is not connected,
the instrument will be coupled to the sensor 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 precompensated to the process conditions provided on the requisition, and will not appear to
be calibrated if checked against room temperature 0 and 100% water level inputs).
If the displacer is not connected, hang the displacer on the torque tube, and re‐zero the instrument by performing the Capture
Zero procedure.
If you received the digital level controller mounted on the sensor and the displacer is not blocked (such as in skid mounted
systems), the instrument will not be coupled, to the sensor, and the lever assembly will be locked. To place the unit in service,
couple the instrument to the sensor, then unlock the lever assembly. You may then perform the Capture Zero procedure.
To review the configuration data entered by the factory, connect the instrument to a 24 VDC power supply as shown in
figure 2‐9. Connect the Field Communicator to the instrument and turn it on. Go to Configure and review the data
under Manual Setup, Alert Setup, and Communications. If your application data has changed since the instrument was
factory‐configured, refer to the Manual Setup section for instructions on modifying configuration data.
For instruments not mounted on a level sensor or when replacing an instrument, initial setup consists of entering
sensor information. The next step is coupling the sensor to the digital level controller. When the digital level controller
and sensor are coupled, the combination may be calibrated.
Sensor information includes displacer and torque tube information, such as:
Length units (meters, inches, or centimeters)
Volume units (cubic inches, cubic millimeters, or milliliters)
Weight units (kilograms, pounds, or ounce)
Displacer Length
Displacer Volume
Displacer Weight
Displacer Driver Rod Length (moment arm) (see table 4‐1)

Configuration Advice
Guided 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, so if
any data is unknown, it is generally safe to accept the defaults. The mounting sense ­ 'instrument left or right of
displacer' - is important for correct interpretation of positive motion. The torque tube rotation is clockwise with rising
level when the instrument is mounted to the right of the displacer, and counter­clockwise when mounted to the left of
the displacer. Use Manual Setup to locate and modify individual parameters when they need to be changed.

a. If you choose “Level” or “Interface,” the default process variable units are set to the same units chosen for
displacer length. You are prompted to key in the level offset. Range values will be initialized based on Level Offset
and displacer size. The default upper range value is set to equal the displacer length and the default lower range
value is set to zero when the level offset is 0.
b. If you choose “Density,” 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”.
5. Select the desired output action: Direct or Reverse
Choosing “reverse acting” will swap the default values of the upper and lower range values (the process variable values
at 20 mA and 4 mA). In a reverse acting instrument, the loop current will decrease as the fluid level increases.

PV alerts are all disabled. Temperature alerts are enabled.
If Density mode was chosen, setup is complete.
If Interface or Density mode was chosen, you are prompted to enter the specific gravity of the process fluid (if

data tables are available that may be entered in the instrument to provide specific gravity correction for temperature
(see tables 4‐2 and 4‐3). For interface level applications, both tables are used. For level measurement applications,
only the lower specific gravity table is used. Neither table is used for density applications. Both tables may be edited
during detailed setup.

You can accept the current table(s), modify an individual entry, or enter a new table manually. For an interface
application, the user can switch between the upper and lower fluid tables.
Note
In firmware version 07 and 08, the data tables for torque‐tube correction are simply stored without implementation. The
information may be used to pre‐compensate the measured torque‐tube rate manually.
Coupling
If the digital level controller is not already coupled to the sensor, perform the following procedure to couple the digital
level controller to the sensor.
1. Slide the access handle to the locked position to expose the access hole. Press on the back of the handle as shown in
figure 2‐4 then slide the handle toward the front of the unit. Be sure the locking handle drops into the detent.
2. Set the displacer to the lowest possible process condition, (i.e. lowest water level or minimum specific gravity) or
replace the displacer by the heaviest calibration weight.
Note
Interface or density applications with displacer/torque tube sized for a small total change in specific gravity are designed to be
operated with the displacer always submerged. In these applications, the torque rod is sometimes resting on a stop while the
displacer is dry. The torque tube does not begin to move until a considerable amount of liquid has covered the displacer. In this
case, couple with the displacer submerged in the fluid with the lowest density and the highest process temperature condition, or
with an equivalent condition simulated with the calculated weights.
If the sizing of the sensor results in a proportional band greater than 100% (total expected rotational span greater than 4.4
degrees), couple the transmitter to the pilot shaft while at the 50% process condition to make maximum use of available
transmitter travel ($6). The Capture Zero procedure is still performed at the zero buoyancy (or zero differential buoyancy)
condition.
3. Insert a 10 mm deep well socket through the access hole and onto the torque tube shaft clamp nut. Tighten the
clamp nut to a maximum torque of 2.1 Nm (18 lbfin).
4. Slide the access handle to the unlocked position. (Press on the back of the handle as shown in figure 2‐4 then slide
the handle toward the rear of the unit.) Be sure the locking handle drops into the detent.

You can enter up to 10 temperature and specific gravity pairs in the table. The table entry function is terminated by
entering zero for the specific gravity. Keep this in mind when setting up a table for a upper fluid, such as steam, whose
specific gravity approaches 0 at lower temperatures.
The resolution of the table entry for specific gravity is 5 decimal places. This means the smallest specific gravity value
you can enter is 0.00001, which should be sufficient to allow a starting temperature around 15.6 C (60 F) for the
steam specific gravity table.
The example set of tables given are generated by visually laying linear segments over a reference curve, and are not
guaranteed to provide any particular accuracy. They are provided to illustrate the guidelines for developing your own
table.
1. Establish a table for the fluid(s) you are using over the expected operating range of process temperature. This
allows you to make best use of the maximum of ten points to obtain the accuracy you require. If your fluid specific
gravity is very linear over the operating temperature range, two data points may be sufficient. (The correction
algorithm provides linear interpolation between data points, and bounds the result at the table end points.)
2. Pick points closer together in regions of higher slope.
3. Pick linear segments that distribute the error equally on each side of the true curve.
Enter or display the specific gravity, or enter values in the specific gravity tables. The Field Communicator prompts for
either a single value for specific gravity or a table of specific gravity versus temperature. To enter a single specific

gravity value, select Single Point and enter the specific gravity value. To display or enter values in the tables, select Table
of SG vs T.
The Field Communicator begins by prompting for the temperature of the first pair in the lower table. After entering
the temperature for the first pair, press ENTER. Enter the specific gravity for the first pair and press ENTER. The Field
Communicator then prompts for the temperature for the second pair. Enter this temperature and press ENTER. The
Field Communicator then prompts for the specific gravity for the second pair. Continue entering each temperature
and specific gravity pair. When finished, enter zero at the Field Communicator prompt for the next specific gravity
value to exit the table. For level applications, the Field Communicator exits to the Instrument Setup menu. For interface
applications, the Field Communicator prompts for the first temperature and specific gravity pair for the upper table.
Enter Constant Density— Enter the density of the process fluid
Measure Density— Select OK to measure the differential density between lower and upper phases of the process fluid.
Note
Measure Density is only visible if PV is Level.
If the instrument and sensor are calibrated, you can have the digital level controller measure the liquid specific gravity,
if it is not known. You must be able to manipulate the level and externally measure it to have the instrument measure
the specific gravity. To work properly, this procedure must be in done in Level measurement mode, and a valid dry
coupling reference must have been obtained at the zero buoyance condition. Use as high a test level as possible to
improve accuracy. Follow the prompts on the Field Communicator and the following procedure to measure specific
gravity:
1. Set the control loop for manual control.
2. Adjust the liquid level so that the displacer is partially submerged.
3. Enter the externally measured level, in engineering units.
After you press OK on the Field Communicator, the instrument begins calculating the specific gravity. You can then
elect to use this value as the specific gravity for all level measurements. If you select No, the instrument uses the
specific gravity entered under PV Setup, or the values from the specific gravity tables.
4. When finished measuring specific gravity, return the control loop to automatic control.

Calibration
Introduction: Calibration of Smart Instruments
Analog instruments generally have only one interface that can be calibrated by the user. A zero and span output
calibration is normally performed at the corresponding two input conditions. Zero/Span calibration is very simple to
use, but provides little versatility. If the 0% and 100% input conditions are not available to the user, a calibration can
sometimes be accomplished, but the gain and offset adjustments will likely interact, requiring considerable iteration
to achieve accuracy. In contrast, intelligent instruments have many interfaces that can be calibrated or scaled by the
user, with consequent increased versatility.
Refer to table 4‐5 for a list of relationships in the DLC3010 that can be calibrated or configured by the user. Note that
not all relationships are listed here.
Table 4‐5. Relationships in the FIELVUE DLC3010 that can be User Calibrated or Configured
Torque Tube Rate
The scale factor between the internal digital representation of the measured pilot shaft rotation and the physical torque
input to the sensor.
Reference (dry) Coupling Point
The angle of pilot shaft rotation associated with the zero buoyancy condition. (The zero reference for the input of the PV
calculation).
Driver Rod Length
The scale factor (moment arm) between a force input to the sensor driver rod and the torque developed as input to the
torque tube.
Displacer Volume
The scale factor relating the density of the process fluid to the maximum force that can be produced as an input to the
driver rod of the sensor.
SG
The density of the process fluid normalized to the density of water at reference conditions. The scale factor that
transforms displacer volume and measured buoyancy into a level signal normalized to displacer length.
Displacer Length
The scale factor to convert normalized level to level on the displacer in engineering units.
Level Offset
The zero reference for the output of the PV calculation, referred to the location of the bottom of the displacer at zero
buoyancy condition.
URV (Upper Range Value)
The value of computed process variable at which a 20 mA output (100% Range) is desired.
LRV (Lower Range Value)
The value of computed process variable at which a 4 mA output (0% Range) is desired.
D/A Trim
The gain and offset of the D/A converter which executes the digital commands to generate output
Instrument Temperature Offset
Bias to improve the accuracy of the ambient temperature measurement used to provide temperature compensation for
the mechanical‐to‐electronic transducer.
Proc Temp Offset
Bias to improve the accuracy of the (RTD) temperature measurement used to provide compensation for
process‐temperature‐related density changes.
These parameters are factory‐set to the most common values for the 249 sensors. Therefore, for the bulk of units sold
in simple level applications, it is possible to accept the defaults and proceed to a simple zero‐and‐span operation. If any
of the advanced features of the instrument are to be used, accurate sensor and test fluid information should generally
be entered before beginning the calibration.

Full Calibration
Field Communicator
Configure > Calibration > Primary > Full Calibration (2-5-1-2)
AMS Device Manager
Configure > Calibration > Primary > Full Calibration
Full Calibration operations compute the sensor gain and offset from two independent observations of process data
points. They are appropriate for cases where the two input conditions can be established relatively quickly in one
session.
Min/Max Calibration
The following procedure can be used to calibrate the sensor if the process condition can be changed to the equivalent
of a completely dry and completely submerged displacer, but the actual precise intermediate values cannot be
observed. (E.g., no sight glass is available, but the cage can be isolated and drained or flooded.)
Correct displacer information and the SG of the test fluid must be entered before performing this procedure.
Follow the prompts on the Field Communicator to calibrate the instrument and sensor.
1. Set the control loop for manual control.
2. Enter the specific gravity for the liquid in the system.
3. Adjust the liquid level until the displacer is dry (or completely submerged in upper liquid). Allow the output to
settle, then acknowledge establishment of the minimum buoyancy condition to the system.
4. Adjust the liquid level until the displacer is completely submerged in the lower liquid. Allow the output to settle,
then acknowledge establishment of the maximum buoyancy condition of the system.
The sensor torque rate is calibrated. If the Capture Zero procedure was run at the minimum buoyancy (or completely
submerged in upper liquid) condition, the zero of the PV calculation will be correct also. Verify that the upper and
lower range values are correct and return the loop to automatic control.
Two Point Calibration
This procedure 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 SG 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.)
An external method of measuring the process condition is required. This procedure may be run before or after marking
the coupling point. It adjusts the calculation gain only, so the change in PV output will track the change in input
correctly after this procedure. However, there may be a constant bias in the PV until the Capture Zero procedure has
been run.
Follow the prompts on the Field Communicator to calibrate the sensor.
1. Put the control loop in manual control.
2. Adjust the process condition to a value near the top or bottom of the valid range.
3. Enter this externally measured process condition in the current PV units.
4. Adjust the process condition to a value near the bottom or top of the valid range, but at a position that is toward the
opposite end of the range relative to the condition used in step 2.
5. Enter this second externally measured process condition in the current PV units.

The sensor torque rate is now calibrated. Be sure to verify that there is no bias in the PV calculation and that the upper
and lower range values are correct before returning the loop to automatic control.
Weight Calibration
This procedure may be used on the bench or with a calibration jig that is capable of applying 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. However, 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. The coupling point should be marked at what is going to be the zero buoyancy weight or the zero
differential‐buoyancy weight, depending on the calibration approach. The instrument should normally be physically
coupled to the pilot shaft at that condition. (However, if the expected operational travel of the pilot is greater than 5
degrees, it is advisable to couple the transmitter to the pilot shaft at the condition representing mid‐travel instead.
This will prevent hitting a stop in the transmitter before limiting in the sensor.) The Capture Zero procedure may be
run either before or after the Weight‐based Cal. However, the PV output is expected to have a bias error until the
Reference Coupling Point is correctly marked.
Follow the prompts on the Field Communicator to calibrate the sensor.
1. For interface level or density measurements, enter the specific gravity of the upper fluid and lower fluid as
requested.
2. Place a weight on the displacer rod that is approximately equal to that indicated on the prompt. The suggested
weight is equivalent to the effective displacer weight when the liquid is at its lowest level or the displacer is
suspended in the liquid with the lower specific gravity.
3. After allowing the system to stabilize, enter the actual value of the weight suspended on the displacer rod.
4. Place a weight on the displacer rod that is approximately equal to that indicated on the prompt. The suggested
weight is equivalent to the effective displacer weight when the liquid is at its highest level or the displacer is
suspended in the liquid with the higher specific gravity.
5. After allowing the system to stabilize, enter the actual value of the weight suspended on the displacer rod.
The sensor torque rate is calibrated. If the Capture Zero procedure was performed at the zero buoyancy (or zero
differential buoyancy) condition, the zero of the PV calculation will be correct also. Check the range values before
putting the loop in service.
Theoretical Calibration
In cases where it is not possible to manipulate the input at all, the user may set up a nominal calibration using
information available about the hardware and the process. The theoretical torque rate for the installed torque tube
may be looked up and compensated for process temperatures. This value is then manually entered in the instrument
configuration. The displacer information and fluid SGs are entered. The desired range values are entered manually.
Finally,Trim Zero computes PV to the current value of the process. It should be possible to control the loop with this
rough calibration.
Note
The theoretical torque rate for the installed torque tube is available in the Simulation of Process Conditions for Calibration of Fisher
Level Controllers and Transmitters instruction manual supplement (D103066X012). Contact your Emerson Process Management
sales office for information on obtaining this manual supplement.

Observations of the sight glass or other independent measurements may be logged against DLC3010 outputs over
time. The ratio of the independent‐observable process changes to the DLC3010 output changes may then be used as a
scale factor to modify the theoretical torque rate stored in the instrument. After each gain adjustment, a new zero
trim will be required. When a plant‐maintenance shutdown occurs, the instrument may be isolated and calibrated in
the normal manner.
Partial Calibration
Field Communicator
Configure > Calibration > Primary > Partial Calibration (2-5-1-3)
AMS Device Manager
Configure > Calibration > Primary > Partial Calibration
Partial Calibration operations are useful when it would take too long to establish a second data point in a single
session. There are of two partial calibrations: capture and trim. The 'capture zero' operation sets the input zero
reference angle to the value currently being measured. It is therefore valid only at the defined zero process condition.
Trim operations recompute either gain or zero reference angle with one observation of process data. The calibration
parameter that is NOT being trimmed is assumed to be correct.
Capture Zero
Capture Zero captures the current value of the torque tube angle as the input zero. The displacer must be loading the
torque tube, and not resting on a travel stop. The torque tube must be coupled to the DLC3010 and the coupling
access door must be closed. In Level mode, the captured angle represents zero differential buoyancy on displacer, and
must be obtained at the actual process zero condition. In Interface and Density mode, the captured angle represents
zero absolute buoyancy on displacer, and must be obtained at actual dry condition.
If the displacer is overweight and it is necessary to use the partial calibration methods, select Level mode and enter the
differential density before using ‘Capture Zero’ and ‘Trim Gain’. After the gain is correct, switch back to Density or
Interface mode, (re­enter individual densities if Interface), then perform a ‘Trim Zero’ procedure to back­compute the
required zero buoyancy angle.
The Capture zero procedure prompts you to verify the instrument is coupled to torque tube, coupling access door is
closed, and verify that the displacer is completely dry.
Note
If the handle on the coupling access door is in the position towards the front of the transmitter, the coupling access hole is open
and the lever is “locked” (pinned in the neutral travel position). In this condition, the true “at‐rest” position of the linkage may not
be captured correctly. Moving the handle to the rear of the transmitter closes the coupling‐access hole and unlocks the lever.
It functions as the pre‐calculation zero for the process measurement algorithm. This procedure can be run either
before or after most of the gain. However, the procedure returns a valid result at only one input condition - zero
buoyancy, although in Level mode, it is equivalent to zero differential buoyancy.
Before calibration, use the Configure > Manual Setup >Sensor menu to verify that all sensor and compensation data
match the calibration conditions.
Trim Gain
Trim Gain operations recompute gain with one observation of process data. The calibration parameter that is NOT
being trimmed is assumed to be correct.
Trim Gain 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, displacer
volume, and driver rod length.
Before calibration, use the Configure > Manual Setup >Sensor menu to verify that all sensor and compensation data
match the calibration conditions.
Trim Zero
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. Use this procedure when the process cannot be moved to zero for capture, but gain is known to be correct
(only a bias error exists).
If the computed process variable is biased due to the inability to capture zero point correctly, (which can happen when
the sensor hardware is oversized to provide additional gain for some interface‐level applications), the Trim Zero can be
used to trim out that bias.
Before calibration, use the Configure > Manual Setup >Sensor menu to verify that all sensor and compensation data
match the calibration conditions.
Note
If displacer sizing for a density application results in an overweight displacer, it will be necessary to set the system up in Level or
Interface measurement mode to calibrate effectively. The output of the instrument will only make sense in “% Range” units in such
a case, since density units are not available in Level or Interface Mode.
Follow the prompts on the Field Communicator.
1. Adjust the process condition or simulation to any valid and observable value.
2. Enter the external observation of the measurement in the current PV units.
Secondary
Temperature Calibration
Field Communicator
Configure > Calibration > Secondary > Temperature Calibration (2-5-2-1)
AMS Device Manager
Configure > Calibration > Secondary > Temperature Calibration
This procedure allows you to display the temperature as measured by the instrument. You can then trim the
temperature reading so that it matches the actual temperature more closely in the region of interest. (This is an offset
adjustment only. There is no ability to change the gain.)
This calibration is initially performed at the factory. Performing it in the field requires an accurate independent
measurement of the instrument housing temperature or process temperature, (as appropriate). The instrument
should be at a steady‐state condition with respect to that temperature when performing the procedure.
Note
The effectiveness of the instrument electronic temperature compensation depends upon the accuracy of the electronics
temperature offset stored in the NVM (non‐volatile memory). If the electronics temperature is incorrect, the temperature curve
applied to the magnets and Hall sensor will be misaligned, resulting in over‐ or under‐compensation.

This procedure allows trimming the gain and offset of the Digital‐to‐Analog (D/A) converter to adjust the accuracy at
which the output follows 4 to 20 mA current commands from the firmware. This relationship is initially set in the
factory, and should not require frequent user adjustment. Reasons for using this procedure include:
Correction for component aging after the instrument has been in service for an extended period.
Adjusting D/A calibration to be optimum at the normal operating temperature, when that temperature is
considerably removed from room temperature conditions.
The procedure is iterative, and will eventually reach a resolution limit where attempts to improve the result will cycle
at a few decimal places to either side of the target.

Calibration Examples
Calibration—with Standard Displacer and Torque Tube
Run the initial calibration near ambient temperature at design span to take full advantage of the available resolution.
This is accomplished by using a test fluid with a specific gravity (SG) close to 1. The value of SG in the instrument
memory during the calibration process should match the SG of the test fluid being used in the calibration. After the
initial calibration, the instrument may be set up for a target fluid with a given specific gravity, or an interface
application, by simple configuration data changes.)
1. Run through Guided Setup and verify that all sensor data is correct.
Procedure:
Change the PV mode to Level
Set the Level Offset value to 0.00
Set the Specific Gravity value to the SG of the test fluid being used.
Establish the test fluid level at the desired process zero point. Make sure that the DLC3010 lever assembly has been
properly coupled to the torque tube (see coupling procedure on page 42). To unlock the lever assembly and allow it to
freely follow the input, close the coupling access door on the instrument. It is often possible to watch the instrument
display and/or the analog output to detect when the fluid hits the displacer, because the output will not start moving
upward until that point is reached.
Select the Min/Max calibration from the Full Calibration menu, and confirm that you are at the 'Min' condition at the
prompt. After the 'Min' point has been accepted, you will be prompted to establish the 'Max' condition. (The 'displacer
completely covered' condition should be slightly higher than the 100% level mark to work correctly. for example, 15
inches above the zero mark would generally be enough for a 14 inch displacer on a 249B, because the amount of
displacer rise expected for that configuration is about 0.6 inch.)
Accept this as the 'Max' condition. Adjust the test fluid level and check the instrument display and current output
against external level at several points distributed across the span to verify the level calibration.
a. To correct bias errors, 'Capture Zero' at the exact zero level condition.
b. To correct gain errors, 'Trim Gain' at a precisely­known high level condition.
If the measured output doesn't come off the low saturation value until the level is considerably above the bottom of
the displacer, it is possible that the displacer is overweight. An overweight displacer will rest on the lower travel stop
until sufficient buoyancy has developed to allow the linkage to move. In that case, use the calibration procedure for
overweight displacers found on page 65.

After the initial calibration:
For a level application— Go to the Sensor Compensation menu and use the 'Enter constant SG' item to configure the
instrument for the target process fluid density.
For an interface application— Change the PV mode to Interface, verify or adjust the range values presented by the
Change PV mode procedure, and then use 'Enter constant SG' to configure the instrument for the SGs of each of the
target process fluids.
For a density application— Change the PV mode to Density, and establish the desired range values in the 'Change PV
mode' procedure.
If the target application temperature is considerably elevated or depressed from ambient, refer to pages 41 and 70 for
information on temperature compensation.
If you are able to adjust both process fluids, the Two Point Calibration is recommended.
If you are unable to carry out Min/Max or Two Point Calibration, then establish zero buoyancy and capture zero. Next,
establish a minimum 5% span above the Lower Range Value and Trim Gain.
If you only have a single fluid for calibration, run through Instrument Setup and verify all displacer data is correct. Set
Level Offset to 0. Select Level application with direct action, and enter SG=1.0 (water) or actual SG of test fluid if
different than 1.0. Proceed with Min/Max or Two Point Calibration.
Note
Information on computing precise simulation of this effect is available in the Simulation of Process Conditions for Calibration of
Fisher Level Controllers and Transmitters instruction manual supplement (D103066X012), available from your Emerson Process
Management sales office or at www.fisher.com.
Calibration with an Overweight Displacer
When the sensor hardware is sized for greater mechanical gain (as it is in some interface or density measurement
applications), the dry displacer weight is often greater than the maximum permissible load on the torque tube. In this
situation it is impossible to 'capture' the zero buoyancy rotation of the torque tube, because the linkage is lying on a
travel stop at that condition.
The 'Capture Zero' routine in the Partial Calibration menu group will therefore not function correctly in the target PV
modes of Interface or Density when the displacer is overweight.
The Full Calibration routines: Min/Max, Two­Point, and Weight, will all work correctly at the actual process conditions
when in interface or density mode, because they back­compute the theoretical zero­buoyancy angle instead of
capturing it.
If it is necessary to use the Partial Calibration methods when the displacer is overweight, the following transformation
may be used:
An interface or density application can be mathematically represented as a level application with a single fluid whose
density is equal to the difference between the actual SGs of the fluid covering the displacer at the two process
extremes.

The calibration process flows as follows:
Change the PV mode to Level.
Set the Level Offset to zero.
Set the Range Values to:
LRV = 0.0,
URV = displacer length.
Capture Zero at the lowest process condition (that is, with the displacer completely submerged in the fluid of
the lowest density ­ NOT dry).
Set Specific Gravity to the difference between the SGs of the two fluids (for example, if SG_upper = 0.87 and
SG_lower = 1.0, enter a specific gravity value of 0.13).
Set up a second process condition more than 5% of span above the minimum process condition, and use the Trim
Gain procedure at that condition. The gain will now be initialized correctly. (The instrument would work fine in
this configuration for an interface application. However, if you have a density application, it won't be possible to
report the PV correctly in engineering units if the instrument calibration is concluded at this point.)
Since you now have a valid gain:
Change the PV mode to Interface or Density,
reconfigure the fluid SGs or range values to the actual fluid values or extremes, and
use the Trim Zero procedure in the Partial Calibration menu to back­compute the theoretical zero­buoyancy
angle.
The last step above will align the value of the PV in engineering units to the sight glass observation.

Following are some guidelines on the use of the various sensor calibration methods when the application uses an
overweight displacer:
Weight‐based: Use two accurately known weights between minimum and maximum buoyancy conditions. The full
displacer weight is invalid because it will put the unit on a stop.
Min/Max: Min now means submerged in the lightest fluid and Max means submerged in the heaviest fluid.
Two point: Use any two interface levels that actually fall on the displacer. Accuracy is better if the levels are farther
apart. The result should be close if you can move the level even 10%.
Theoretical: If the level cannot be changed at all, you can enter a theoretical value for torque tube rate manually. In
this case you would not be able to Capture Zero at the 0% interface condition.

Density Applications - with Standard Displacer and Torque Tube
Note
When you change 'PV is' from level or interface to density, the range values will be initialized to 0.1 and 1.0 SGU. You may edit the
range values according to the specify gravity unit.
It is necessary to back out of Manual Setup and re­enter the Manual Setup menu to see the changes being refreshed.
If the displacer is overweight, there is no way to get the output numerically correct in density mode, because the Level
Offset is not available. Therefore, density calibration normally has to begin with the assumption that the displacer is
free moving at zero buoyancy (dry) conditions. Capture Zero accurately at dry displacer conditions, and any of the full
sensor calibration methods (Weight, Min/Max, and Two Point) can be used in density mode. The terminology can be
confusing, because it usually refers to a “level” as the process condition to set up. When using one of these method,
remember that you are in the density mode and enter observed PV in current units of SGU, g/L, lb/in3, kg/m3, etc.
Weight Based: The Weight Calibration asks you for the lowest and highest density you want to use for the calibration
points, and computes weight values for you. If you can't come up with the exact values asked for, you are allowed to
edit the values to tell it what weights you actually used.
Min/Max: The Min/Max Calibration essentially reverts to level mode during the calibration process. It asks for the SG of
your test fluid first. Then, it has you set up first a dry and then a completely submerged displacer condition.
Two Point: The Two Point Calibration requires you to set up two different process conditions with as much difference
as possible. You could use two standard fluids with well‐known density and alternately submerge the displacer in one
or the other. If you are going to try to simulate a fluid by using a certain amount of water, remember that the amount
of displacer covered by the water is what counts, not the amount in the cage. The amount in the cage will always need
to be slightly more because of the displacer motion. Because of this inconvenience, and the extra work of draining and
flooding with two fluids, the two‐point calibration method is probably the least attractive in density mode.
Note
These calibration methods advise you to trim zero for better accuracy. That command is not available in density mode.
Sensor Calibration at Process Conditions (Hot Cut‐Over) when input cannot be varied
If the input to the sensor cannot be varied for calibration, you can configure the instrument gain using theoretical
information and use Trim Zero to trim the output to the current process condition. This allows you to make the
controller operational and to control a level around a setpoint. You can then use comparisons of input changes to
output changes over time to refine the gain estimate. A new trim zero will be required after each gain adjustment. This
approach is not recommended for a safety‐related application, where exact knowledge of the level is important to
prevent an overflow or dry sump condition. However, it should be more than adequate for the average level‐control
application that can tolerate large excursions from a midspan set point.
There are a number of calibration methods available in the DLC3010 Device Description. Two Point Calibration allows
you to calibrate the torque tube using two input conditions that put the measured interface anywhere on the
displacer. The accuracy of the method increases as the two points are moved farther apart, but if the level can be
adjusted up or down a minimum 5% span, it is enough to make a calculation. Most level processes can accept a small,
manual adjustment of this nature. If your process cannot, then the theoretical approach is the only method available.

1. Determine all the information you can about the 249 hardware: 249 type, mounting sense (controller to the right or
left of displacer), torque tube material and wall thickness, displacer volume, weight, length, and driver rod length.
(the driver rod length is not the suspension rod length, but the horizontal distance between the centerline of the
displacer and the centerline of the torque tube). Also obtain process information: fluid densities, process
temperature, and pressure. (The pressure is used as a reminder to consider the density of an upper vapor phase,
which can become significant at higher pressures.)
2. Run Instrument Setup and enter the various data that is requested as accurately as possible In Manual Setup. Set
the Range Values (LRV, URV) to the PV values where you will want to see 4 mA and 20 mA output, respectively.
These might be 0 and 14 inches on a 14 inch displacer.
3. Mount and couple at the current process condition. It is not necessary to run the Capture Zero procedure, because
it stores the current torque tube angle as the zero buoyancy condition, and will therefore not be accurate.
4. With the torque tube type and material information, find a theoretical value for the composite or effective
torque-tube rate, (Refer to the Entering Theoretical Torque Tube (TT) Rates procedure in this section), and enter it
in the instrument memory. The value can be accessed by selecting Configure > Manual Setup > Sensor > Torque Tube
> Change Torque Rate
5. If the process temperature departs significantly from room temperature, use a correction factor interpolated from
tables of theoretical normalized modulus of rigidity. Multiply the theoretical rate by the correction factor before
entering the data. You should now have the gain correct to within perhaps 10%, at least for the standard wall, short
length torque tubes. (For the longer torque tubes (249K, L, N) with thin‐wall and a heat insulator extension, the
theoretical values are much less accurate, as the mechanical path departs considerably from the linear theory.)
Note
Tables containing information on temperature effects on torque tubes can be found in the Simulation of Process Conditions for
Calibration of Fisher Level Controllers and Transmitters instruction manual supplement (D103066X012), available from your
Emerson Process Management sales office or at www.fisher.com.
6. Now using a sight glass or sampling ports, obtain an estimate of the current process condition. Run the Trim Zero
calibration and report the value of the actual process in the PV engineering units.
7. You should now be able to go to automatic control. If observations over time show the instrument output exhibits,
for example,1.2 times as much excursion as the sight glass input, you could divide the stored torque tube rate by
1.2 and send the new value to the instrument. Then run another Trim Zero calibration and observe results for
another extended period to see if further iteration is required.
Entering Theoretical Torque Tube (TT) Rates
The Simulation of Process Conditions for Calibration of Fisher Level Controllers and Transmitters instruction manual
supplement (D103066X012) provides the theoretical composite torque tube (TT) rate for 249 sensors with DLC3010
controllers. These numbers are nominal values. They should be within 10% of the values that the instrument would
compute when you perform a sensor calibration. They will be less accurate for the long torque tubes (249K, L, N, VS,
and P), especially with thin‐wall constructions.
If you are unable to perform a sensor calibration during installation, you may enter the values into the instrument at
the following menu item in the handheld: Configure > Manual Setup > Sensor > Torque Tube > Change Torque Rate
Then, manually set the LRV and URV to the PV values at which you desire 4 and 20 mA output, respectively: Configure >
Manual Setup > Variables > Primary Variable Range > Upper or Lower Range Value
Next, perform a Trim Zero operation to align the instrument output with the sight glass reading: Configure > Calibration
> Primary > Partial Calibration > Trim Zero
These steps will provide an approximate PV calibration to get a system operational. Further refinements can then be
made when it is possible to manipulate and observe the level and instrument output.

Excessive Mechanical Gain
If the displacer/torque tube sizing provides more than 4.4 degrees of torque tube rotation for a full span change in
process input, It may be difficult to obtain a valid calibration with the normal coupling procedure. In such a case, you
can utilize the full mechanical span of the DLC3010 by coupling the instrument to the torque tube at the 50% travel
condition, instead of at the lowest process condition. When coupled at the 50% travel condition, the travel limits of the
249 hardware will be the constraining factor. If the 249 travel limit is reached before full process input travel is
achieved, the hardware is either improperly sized for the application, improperly assembled, or damaged.
Determining the SG of an Unknown Fluid
If the instrument has been calibrated with weights or by using a test fluid with a well­known SG, it is possible to use the
instrument to measure the SG of an unknown fluid, or the differential SG between two fluids. A procedure called
'Measure Density' is provided in the Manual Setup ­ Process Fluid menu when you are in Level measurement mode. The
procedure presents the measured value and allows you either to automatically move it into the instrument
configuration, or to manually record it for later use.
Accuracy Considerations
Effect of Proportional Band
If you are operating at low Proportional Band [PB = 100% times (full span torque tube rotation) / (4.4 degrees)], you
can expect a degradation factor of about (100%)/(PB%) on the Transmitter 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 DLC3010, 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, (because the zero buoyancy condition
will occur with the linkage driven hard into a travel stop). In interface measurement mode it becomes impossible to
Capture Zero. One simple and effective solution is to use Level measurement mode. Capture Zero at the lowest
process condition instead of zero buoyancy, and enter the differential SG = (SGlowerfluid - SGupperfluid). The
algorithm then computes level correctly.
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 of the
displacer, and zero at the opposite extreme process condition.
69
Configuration
September 2013
Instruction Manual
D102748X012
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 transmitter memory to match the actual process condition. Frequent automatic updates
to this variable are not advised, as the NVM location where it is stored has an expected lifetime of about 10,000 write
operations. If changes are only a function of temperature, the characteristic of the fluid can be loaded once in the NVM
table, and an RTD connected to measure the process temperature and drive the correction 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.
Extreme Process Temperatures
For applications that will run at extreme temperatures, the effect of process temperature on the torque tube must be
taken into account. 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
Transmitters instruction manual supplement (D103066X012), available from your Emerson Process Management sales office or at
www.fisher.com.
Temperature Compensation
If the process temperature departs significantly from calibration temperature, you will need to apply a correction
factor. Interpolate the correction factor from the material‐specific tables of theoretical normalized modulus of rigidity
versus temperature, as described in the Simulation of Process Conditions for Calibration of Fisher Level Controllers and
Transmitters instruction manual supplement (D103066X012). Multiply the measured torque tube rate (editable in the
review menu under factory settings) by the correction factor and enter the new value. When you cannot calibrate at
process temperature this approach allows a better approximation of the actual torque tube behavior at process
conditions.

Section 6 Maintenance & Troubleshooting6‐6‐
The DLC3010 digital level controller features a modular design for easy maintenance. If you suspect a malfunction,
check for an external cause before performing the diagnostics described in this section.
Sensor parts are subject to normal wear and must be inspected and replaced as necessary. For sensor maintenance
information, refer to the 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
the product specifications, as indicated in table 1‐1. It may also impair operations and the intended function of the device.
Diagnostic Messages
In addition to the output, the LCD meter displays abbreviated diagnostic messages for troubleshooting the digital
level controller. To accommodate two‐word messages, the display alternates between the first and second word. The
meter displays messages simultaneously on the Process Variable and Process Variable Unit lines as shown in figure 6‐1.
Messages on the Process Variable line refer to general device conditions, while messages on the Process Variable Unit
line refer to specific causes for these conditions. A description of each diagnostic message follows.

[BLANK]— If the meter does not appear to function, and the instrument is otherwise functioning correctly, make
sure the digital level controller is configured for the LCD meter. The meter will not function if the LCD Configuration
selection is “Not Installed.” To check this function, connect the Field Communicator to the digital level controller
and turn it on. From the Online menu, select Configure > Manual Setup > Instrument Display > LCD Configuration. For
information on setting up the LCD meter see page 51. A diagnostic test for meter function is also detailed later in
this section.
FAIL HDWR— This message indicates the existence of one or more of the following conditions:
—The primary sensor input conversion is out of range.
—The primary sensor drive current is out of range.
—The internal reference voltage for controlling the loop current is out of range.
Perform the diagnostic procedures detailed later in this section to isolate the specific failure. If diagnostics indicate a
failure of a particular module, replace the indicated module with a new one. Otherwise, correct the mechanical input
condition to clear the message.
OFLOW— The location of the decimal point, as configured in the meter setup, is not compatible with the value to be
displayed by the meter. For example, if the meter is measuring a level greater that 99.999 mm, and the meter
decimal point is set to 3 digit precision, the meter will display an “OFLOW” message because it is only capable of
displaying a maximum value of 99.999 when set to 3 digit precision. The position of the decimal point may be
adjusted by using the Field Communicator. From the Online menu, select Configure > Manual Setup > Instrument
Display > Decimal Places. Selecting “0” will put the display in auto‐scale mode. (The number of decimal places
displayed will be the maximum remaining in the display field for the current value of PV.)
Hardware Diagnostics
If you suspect a malfunction despite the absence of diagnostic messages on the Field Communicator display, follow
the procedures described in table 6‐1 to verify that the digital level controller hardware and process connections are in
good working order. Under each of the major symptoms, specific suggestions are offered for solving problems. Always
deal with the most likely and easiest‐to‐check conditions first.

Test Terminals
Test connections inside the terminal box can be used to measure loop current. These terminals are across an internal 1
ohm resistor that is in series with the loop.
1. Remove the terminal box cap.
2. Adjust the test meter to measure a range of 0.001 to 0.1 volts.
3. Connect the positive lead of the test meter to the + connection and the negative lead to the T connection inside the
terminal box.
4. Measure Loop current as:
Voltage (on test meter) 1000 = milliamps
example:
Test meter Voltage X 1000 = Loop Milliamps
0.004 X1000 = 4.0 milliamperes
0.020 X 1000 = 20.0 milliamperes
5. Remove test leads and replace the terminal box cover.
Removing the Digital Level Controller from the Sensor
Because of its modular design, most of the service and maintenance to the digital level controller can be done without
removing it from the sensor. However, if necessary to replace sensor to instrument mating parts or parts in the
transducer housing, or to perform bench maintenance, perform the following procedures to remove the digital level
controller from the sensor.
WARNING
On an explosion‐proof instrument, remove the electrical power before removing the instrument covers in a hazardous
area. Personal injury or property damage may result from fire and explosion if power is applied to the instrument with the
covers removed.

Removing the DLC3010 Digital Level Controller from a 249 Sensor
249 Sensor in Standard Temperature Applications
1. Loosen the set screw (key 31) in the terminal box cover assembly (key 6) so that the cover can be unscrewed from
the terminal box.
2. After removing the cover (key 6), note the location of field wiring connections and disconnect the field wiring from
the wiring terminals.
3. As shown in figure 2‐4, locate the access handle on the bottom of the transducer housing. Using a 2 mm hex key,
back out the set screw in the depression on the access handle until it is flush with the handle surface. Press on the
back of the handle, as shown in the figure, and slide the handle toward the front of the unit, (the 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.
4. Using a 10 mm deep well socket inserted through the access hole, loosen the shaft clamp (figure 2‐4).
5. Loosen and remove the hex nuts (key 34) from the mounting studs (key 33).
6. Carefully pull the digital level controller straight off the sensor torque tube.
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 of the sensor torque
tube.

2. Apply a thin coat of a light grade of grease to the internal thread of the hole for the lever mounting bolt.
3. Hold lever assembly by coupling block and guide the flexure block into its aligning slot in the housing without
applying any downward force to the sprung parts of the lever assembly.
CAUTION
To prevent damage to the flexure when inserting the flexure block into its aligning slot in the housing, apply pressure to
the flexure block only.
A long pin inserted into the bolt‐hole in the flexure block may be used to pull it against the inside corner of the aligning
slot.
4. Secure the block by reinstalling the M5x20 socket‐head cap screw (key 14). Torque to 2.8 Nm (25 lbfin) $10%.
5. Mark bolt head and block with a movement‐detecting sealant.
6. Install the coupling shield (key 16) and secure with the two screws (key 13). Tighten the screws to 0.48 Nm

Appendix A Principle of OperationA‐
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
represent the digits 1 and 0 (see figure A‐1). The average value of this sinewave is zero, therefore no DC value is added
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.
Figure A‐2 shows a typical multidrop network. Do not use this figure as an installation diagram. Contact your Emerson
Process Management sales office with specific requirements for multidrop applications.

The Field Communicator can test, configure, and format a multidropped DLC3010 digital level controller in the same
way as in a standard point‐to‐point installation.
Note
DLC3010 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 DLC3010 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; process variable
(level, interface level, or density); the process temperature, if an RTD (resistance temperature detector) is installed;
the degrees of torque tube rotation; and percent range.
The instrument uses a microcontroller and associated electronic circuitry to measure the process variable, provide a
current output, drive the LCD meter, and provide HART communications capability. Figure A‐3 shows the digital level
controller assembly. Figure A‐4 is a block diagram of the main components in the instrument electronics; the LCD
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.

The transducer board contains the Hall sensor, a temperature sensor to monitor the Hall sensor temperature, and an
EEPROM to store the coefficients associated with the Hall sensor. The terminal board contains the EMI filters, the loop
connection terminals, and the connections for the optional RTD used to measure process temperature.
A level, density, or interface level change in the measured fluid causes a change in the displacer position (figure A‐5).
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.

249 SENSOR (SIDE VIEW)
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
output signal ranges between 4 and 20 mA and is proportional to the input. See figure A‐6. If the input should exceed
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 3.7 or 22.5 mA,
depending upon the position of the alarm jumper.

Note
The upper alarm value is compliant with NAMUR NE‐43, but the lower alarm value is not.
If using in a system with NAMUR NE‐43 compatibility, the high alarm value may be an appropriate choice.
Other circuits in the digital level controller provide reverse polarity protection, transient power surge protection, and
electromagnetic interference (EMI) protection.

Glossary
Alarm Deadband
The amount by which the process variable must
return within normal limits for the alarm to clear.
Alarm Limit
An adjustable value that, when exceeded,
activates an alert.
Control Loop
An arrangement of physical and electronic
components for process control. The electronic
components of the loop continuously measure
one or more aspects of the process, then alter
those aspects as necessary to achieve a desired
process condition. A simple control loop
measures only one variable. More sophisticated
control loops measure many variables and
maintain specified relationships among those
variables.
Algorithm
A set of logical steps to solve a problem or
accomplish a task. A computer program contains
one or more algorithms.
Alphanumeric
Consisting of letters and numbers.
ANSI (acronym)
The acronym ANSI stands for the American
National Standards Institute
Burst
Burst mode is an extension to HART protocol that
provides the continuous transmission of standard
HART command response by a field device.
Damping
Output function that increases the time constant
of the digital level controller output to smooth
the output when there are rapid input variations.
Descriptor
Sixteen‐character field for additional
identification of the digital level controller, its
use, or location. The descriptor is stored in the
instrument and can be changed using a Field
Communicator and the device information
function.
Device ID
Unique identifier embedded in the instrument at
the factory.
Device Revision
Byte
A unit of binary digits (bits). A byte consists of
eight bits.
Revision number of the interface software that
permits communication between the Field
Communicator and the instrument.
Firmware Revision
Commissioning
Functions performed with a Field Communicator
and the digital level controller to test the
instrument and loop and verify digital level
controller configuration data.
Configuration
Stored instructions and operating parameters for
a FIELDVUE Instrument.
The revision number of the instrument firmware.
Firmware is a program that is entered into the
instrument at time of manufacture and cannot be
changed by the user.
Free Time
Percent of time that the microprocessor is idle. A
typical value is 25%. The actual value depends on
the number of functions in the instrument that
are enabled and on the amount of
communication currently in progress.

Gain
The ratio of output change to input change.
Hardware Revision
Revision number of the Fisher instrument
hardware. The physical components of the
instrument are defined as the hardware.
Menu
A list of programs, commands, or other activities
that you select by using the arrow keys to
highlight the item then pressing ENTER, or by
entering the numeric value of the menu item.
Message
Thirty‐two character field for any additional
information the user may want to include.
HART (acronym)
The acronym HART stands for Highway
Addressable Remote Transducer. The
communications standard that provides
simultaneous analog and digital signal
transmission between control rooms and field
devices.
HART Tag
An eight‐character field for identifying the digital
level controller. The HART tag is stored in the
instrument and can be changed using a Field
Communicator and the device information
function.
HART Universal Revision
Revision number of the HART Universal
Commands which are the communications
protocol for the instrument.
Instrument Serial Number
The serial number assigned to the instrument.
Lower Range Value (LRV)
Lowest value of the process variable that the
digital level controller is currently configured to
measure in the 4 to 20 mA loop.
Lower Sensor Limit (LSL)
Lowest value of the process variable that the
digital level controller can be configured to
measure.
Memory
A type of semiconductor used for storing
programs or data. FIELDVUE instruments use
three types of memory: Random Access Memory
(RAM), Read Only Memory (ROM), and
Non‐Volatile Memory (NVM). See also these
listings in this glossary.
114
Multidropping
The connection of several field devices to a single
communications transmission line.
Non‐Volatile Memory (NVM)
A type of semiconductor memory that retains its
contents even though power is disconnected.
NVM contents can be changed during
configuration unlike ROM which can be changed
only at time of instrument manufacture. NVM
stores configuration data.
On‐Line Configuration
Configuration of the digital level controller
operational parameters using a Field
Communicator connected to the instrument.
Parallel
Simultaneous: said of data transmission on two or
more channels at the same time.
Polling Address
Address of the instrument. If the digital level
controller is used in a point‐to‐point
configuration, set the polling address to 0. If it is
used in a multidrop configuration, or split range
application, set the polling address to a value
from 0 to 15.
Process Variable (PV)
A physical quality or quantity which is monitored
as part of a control strategy. The digital level
controller can measure level, interface level
between two liquids of different specific gravity,
and liquid density.
Protocol
A set of data formats and transmission rules for
communication between electronic devices.
Devices that conform to the same protocol can
communicate accurately.
Instruction Manual
Glossary
D102748X012
Random Access Memory (RAM)
A type of semiconductor memory that is normally
used by the microprocessor during normal
operation that permits rapid retrieval and storage
of programs and data. See also Read Only
Memory (ROM) and Non‐Volatile Memory (NVM).
Read‐Only Memory (ROM)
A memory in which information is stored at the
time of instrument manufacture. You can
examine but not change ROM contents.
September 2013
Software
Microprocessor or computer programs and
routines that reside in alterable memory (usually
RAM), as opposed to firmware, which consists of
programs and routines that are programmed into
memory (usually ROM) when the instrument is
manufactured. Software can be manipulated
during normal operation, firmware cannot.
Span
Algebraic difference between the upper and
lower range values.
Reranging
Configuration function that changes the digital
level controller 4 to 20 mA settings.
RTD
The abbreviation for resistance temperature
detector. Temperature is measured by the RTD by
correlating the resistance of the RTD element
with temperature.
Temperature Sensor
A device within the instrument that measures the
instrument's internal temperature.
Upper Range Value (URV)
Highest value of the process variable that the
digital level controller is currently configured to
measure in the 4 to 20 mA loop.
Send Data
A Field Communicator command that transfers
configuration data from the Field
Communicator's working register to the digital
level controller memory.
Upper Sensor Limit (USL)
Highest value of the process variable that the
digital level controller can be configured to
measure.
SI Units
The International System of Units. Includes
metric units such as ampere (A), meter (m),
kilogram (kg), Kelvin (K), and second (s).
Working Register
Memory location in a Field Communicator that
temporarily stores data as it is being entered.
