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.

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
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.

Available Configurations

DLC3010 Digital Level Controller:

Mounts on caged and cageless 249 sensors. See
tables 1‐6 and 1‐7 and sensor description.

Function: Transmitter
Communications Protocol: HART

Input Signal

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.

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

Output Signal

Analog: 4‐20 milliamperes DC (

Jdirect

action—increasing level, interface, or density
increases output; or

Jreverse action—increasing

level, interface, or density decreases output)

High saturation: 20.5 mA
Low saturation: 3.8 mA
High alarm: 22.5 mA
Low Alarm: 3.7 mA

Only one of the above high/low alarm definitions is
available in a given configuration. NAMUR NE 43
compliant when high alarm level is selected.

Digital: HART 1200 Baud FSK (frequency shift keyed)

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 600 ohms. The transmitter HART receive
impedance is defined as:

Rx: 42K ohms and
Cx: 14 nF

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.

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 80_C (-40 to 176_F)

Process Temperature: The torque rate is affected by
the process temperature (see figure 1‐2 and 1‐3). The
process density may also be affected by the process
temperature.

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.

Minimum Differential Specific Gravity

With a nominal 4.4 degrees torque tube shaft
rotation for a 0 to 100 percent change in liquid level
(specific gravity=1), the digital level controller can be
adjusted to provide full output for an input range of
5% of nominal input span. This equates to a minimum
differential specific gravity of 0.05 with standard
volume displacers.

Minimum Differential Specific Gravity (continued)

(100 in3).

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.

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

August 2020

Section 2 Installation2-2-

This 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 handle. When the handle 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 39.

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 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 set the access handle in the open or closed position, 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.

Hazardous Area Classifications and Special Instructions for “Safe Use” and
Installations in Hazardous Locations

Refer to the DLC3010 Quick Start Guide (D103214X012) that ships with the instrument for Hazardous Area
Classifications and Special Instructions for “Safe Use” and Installations in Hazardous Locations. If a copy of this quick
start guide is needed contact your Emerson sales office

or go to Fisher.com.

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

this.

Installation

August 2020

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.

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 NSm (88.5 lbfSin).

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 600
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.

Operating
Region

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.

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 mm
and earth ground when flammable or hazardous gases are present. Refer to national and local codes and standards for
grounding requirements.

2

) ground strap between the digital level controller

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.

24

DLC3010 Digital Level Controller

Instruction Manual

D102748X012

Installation

August 2020

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.

Note

During Manual Setup
of 1 ohm.

, you must specify the connecting wire resistance for a 2‐wire RTD. 250 feet of 16 AWG wire has a resistance

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.

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.

Instruments

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 if the PV violates a user-defined alert threshold
while a HiHi or LoLo PV monitor is enabled. 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.

Loop Test

Field Communicator Service Tools > Maintenance > Tests > Loop Test (3-4-1-2)

Loop test can be used to verify the controller output, the integrity of the loop, and the operations of any recorders or
similar devices installed in the loop. To initiate a loop test, perform the following procedure:

1. Connect a reference meter to the controller. To do so, either connect the meter to the test connections inside the
terminal box (see the Test Connections procedure) or connect the meter in the loop as shown in figure 2‐9.

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.

Installation in Conjunction with a Rosemount 333 HART Tri‐Loop
HART‐to‐Analog Signal Converter

Use the DLC3010 digital level controller in operation with a Rosemount 333 HART Tri-Loop HART‐to‐Analog Signal
Converter to acquire an independent 4‐20 mA analog output signal for the process variable, % range, electronics
temperature, and process temperature. The Tri‐Loop divides the digital signal and outputs any or all of these variables
into as many as three separate 4‐20 mA analog channels.

Refer to figure 2‐13 for basic installation information. Refer to the 333 HART Tri‐Loop HART‐to‐Analog Signal

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), and tertiary (TV) variables. Depending upon the burst option selected, the digital level
controller will burst the variables as shown in table 2‐1.

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.
