Installation

WARNING

Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before mounting the product:

D Do not install any system component where service conditions could exceed the limits given in this manual or the limits

on the appropriate nameplates. Use pressure‐relieving devices as required by government or accepted industry codes and good engineering practices.

D Always wear protective gloves, clothing, and eyewear when performing any installation operations.

D Do not remove the actuator from the valve while the valve is still pressurized.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

from both sides of the valve.

D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not

applying force to the valve stem; this will allow for the safe removal of the stem connector.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D The instrument is capable of supplying full supply pressure to connected equipment. To avoid personal injury and

equipment damage, caused by sudden release of process pressure or bursting of parts, make sure the supply pressure never exceeds the maximum safe working pressure of any connected equipment.

D Severe personal injury or property damage may occur from an uncontrolled process if the instrument air supply is not

clean, dry and oil‐free, or noncorrosive gas. While use and regular maintenance of a filter that removes particles larger than 40 microns will suffice in most applications, check with an Emerson field office and Industry Instrument air quality standards for use with corrosive gas or if you are unsure about the proper amount or method of air filtration or filter maintenance.

D For corrosive media, make sure the tubing and instrument components that contact the corrosive media are of suitable

corrosion-resistant material. The use of unsuitable materials might result in personal injury or property damage due to the uncontrolled release of the corrosive media.

D If natural gas or other flammable or hazardous gas is to be used as the supply pressure medium and preventive

measures are not taken, personal injury and property damage could result from fire or explosion of accumulated gas or from contact with hazardous gas. Preventive measures may include, but are not limited to: Remote venting of the unit, re‐evaluating the hazardous area classification, ensuring adequate ventilation, and the removal of any ignition sources.

D To avoid personal injury or property damage resulting from the sudden release of process pressure, use a high‐pressure

regulator system when operating the controller or transmitter from a high‐pressure source.

The instrument or instrument/actuator assembly does not form a gas‐tight seal, and when the assembly is in an enclosed area, a remote vent line, adequate ventilation, and necessary safety measures should be used. Vent line piping should comply with local and regional codes and should be as short as possible with adequate inside diameter and few bends to reduce case pressure buildup. However, a remote vent pipe alone cannot be relied upon to remove all hazardous gas, and leaks may still occur.

D Personal injury or property damage can result from the discharge of static electricity when flammable or hazardous

gases are present. Connect a 14 AWG (2.08 mm flammable or hazardous gases are present. Refer to national and local codes and standards for grounding requirements.

D Personal injury or property damage caused by fire or explosion may occur if electrical connections are attempted in an

area that contains a potentially explosive atmosphere or has been classified as hazardous. Confirm that area classification and atmosphere conditions permit the safe removal of covers before proceeding.

D Personal injury or property damage, caused by fire or explosion from the leakage of flammable or hazardous gas, can

result if a suitable conduit seal is not installed. For explosion‐proof applications, install the seal no more than 457 mm (18 inches) from the instrument when required by the nameplate. For ATEX applications use the proper cable gland certified to the required category. Equipment must be installed per local and national electric codes.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

Maintenance

WARNING

Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations on an actuator‐mounted instrument or accessory:

D Always wear protective gloves, clothing, and eyewear.

D Provide some temporary measure of control to the process before taking the instrument out of service.

D Provide a means of containing the process fluid before removing any measurement devices from the process.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

from both sides of the valve.

D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not

applying force to the valve stem; this will allow for the safe removal of the stem connector.

D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

When using natural gas as the supply medium, or for explosion proof applications, the following warnings also apply:

D Remove electrical power before removing any housing cover or cap. Personal injury or property damage from fire or

explosion may result if power is not disconnected before removing the cover or cap.

D Remove electrical power before disconnecting any of the pneumatic connections.

D When disconnecting any of the pneumatic connections or any pressure retaining part, natural gas will seep from the

unit and any connected equipment into the surrounding atmosphere. Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and appropriate preventive measures are not taken. Preventive measures may include, but are not limited to, one or more of the following: ensuring adequate ventilation and the removal of any ignition sources.

D Ensure that all housing caps and covers are correctly installed before putting this unit back into service. Failure to do so

could result in personal injury or property damage from fire or explosion.

Instruments Mounted on Tank or Cage

WARNING

For instruments mounted on a tank or displacer cage, release trapped pressure from the tank and lower the liquid level to a point below the connection. This precaution is necessary to avoid personal injury from contact with the process fluid.

Instruments With a Hollow Displacer or Float

WARNING

For instruments with a hollow liquid level displacer, the displacer might retain process fluid or pressure. Personal injury and property might result from sudden release of this pressure or fluid. 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. A displacer that has been penetrated by process pressure or fluid might contain:

D pressure as a result of being in a pressurized vessel

D liquid that becomes pressurized due to a change in temperature

D liquid that is flammable, hazardous or corrosive.

Handle the displacer with care. Consider the characteristics of the specific process liquid in use. Before removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.

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.

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.

Table 1‐1. DLC3010 Digital Level Controller Specifications (continued)

Instruction Manual

D102748X012

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 cm

), most others have standard volume of ∼1640 cm

(60

(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.

Construction Materials

Installation

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.

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.

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.

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.

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)

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.

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 mm 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.
