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 HARTR 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)

D 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)

D 249BP, 249CP, and 249P sensors top mount on the vessel with the displacer hanging down into the vessel.

D 249VS sensor side mounts on the vessel with the displacer hanging out into the vessel.

D 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.

NOTE: At full design span, reference conditions. 1. To lever assembly rotation inputs.

At effective proportional band (PB)<100%, linearity, dead band, and repeatability are derated by the factor (100%/PB)

Operating Influences

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:

Pulse Waveform		Max VCL	Max IPP
Rise Time	Decay to	(Clamping	(Pulse Peak
(ms)	50% (ms)	Voltage) (V)	@ Current) (A)
10	1000	93.6	16
8	20	121	83

Note: μs = microsecond

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). 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.

Introduction and Specifications	Instruction Manual
October 2014	D102748X012
Table 1 1. DLC3010 Digital Level Controller Specifications (continued)

Minimum Differential Specific Gravity (continued)

See 249 sensor specifications for standard displacer volumes and standard wall torque tubes. Standard volume for 249C and 249CP sensors is 980 cm3 (60 in3), most others have standard volume of 1640 cm3 (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.

Section 2 Installation

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 38.

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 Process Management sales office or visit our website at www.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 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.

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 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 1100 ohms must be present in the loop for communication with a Field Communicator. Refer to figure 2 9 for current loop connections.

E0363

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

20

Instruction Manual	Installation
D102748X012	October 2014

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.

Loop Test

Field Communicator	Service Tools > Maintenance > Tests > Loop Test (3-3-1-1) or (3-3-1-2) if LCD Configuration is installed

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.

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 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.
