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 DLC3020f digital level 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) will be in the unlocked position. Remove the displacer blocking hardware before calibration (see the appropriate sensor instruction manual). The coupling should be intact.

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, couple the instrument to the sensor as follows:

a. Slide the access handle to the open position to lock the lever assembly in place and expose the access hole. Press

on the back of the handle as shown in figure 2 then slide the handle toward the front of the unit. Be sure the locking handle drops into the detent.

b. If in process, ensure that the level or interface is in the lowest position on the displacer.

c. If on the bench, ensure that the displacer is dry and the displacer rod lever arm is not hitting a travel stop.

d. 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 NSm (18 lbfSin).

e. Slide the access handle to the closed position. for operation or calibration. (Press on the back of the handle as

shown in figure 2 then slide the handle toward the rear of the unit.) Be sure the locking handle drops into the detent.

Mounting

WARNING

To avoid personal injury or property damage, 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 the left image in figure 3. If the sensor has a cageless displacer, the sensor mounts on the side or top of the vessel as shown in the right image in figure 3.

Quick Start Guide

D103470X012

DLC3020f Digital Level Controller

July 2012

The DLC3020f 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.

DLC3020f Orientation

Mount the DLC3020f with the torque tube shaft clamp access hole (see figure 2) pointing downward to allow accumulated moisture drainage.

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 4. 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 249 caged 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 4. To rotate the head, remove the head flange bolts and nuts and position the head as desired.

Mounting the DLC3020f on a 249 Sensor

Refer to figure 2 unless otherwise indicated.

1. If the set screw in the access handle (figure 5) 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 open position to lock the lever assembly in place and to expose the access hole. Press on the back of the handle as shown in figure 2 then slide the handle toward the front of the unit. Be sure the locking handle drops into the detent.

2. Using a 10 mm deep well socket inserted through the access hole, loosen the shaft clamp (figure 2).

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.

Confirm Time

Confirm Time determines the time in 1/32 of a millisecond, the instrument waits for confirmation of receipt of a report before trying again. If Confirm Time is 0, the instrument does not try to resend the report. Enter 0 or a value between 320000 (10 seconds) and 640000 (20 seconds).

Communication Timeout

Rcas Time‐Out—Rcas Timeout determines how long function blocks in the DLC3020f should wait before giving up on remote computer writes to RCas parameters. When the timeout is exceeded, the block sheds to the next mode as defined by the block shed options. If RCas Timeout is set to 0, the block will not shed from RCas. Enter a positive value in the RCas Timeout Timeout field. Time duration is in 1/32 milliseconds (640000 = 20 secs).

Note

Typically this parameter does not need to be changed. The unit will be operational using the default values assigned by the factory. Perform this procedure only if a remote computer is sending setpoints from your “advanced” control.

Default value for RCas Timeout is 20 seconds.

Rout Time-Out—ROut Timeout (SHED_ROUT [27]) determine how long function blocks in the DLC3020f should wait before giving up on computer writes to ROut parameters. When the timeout is exceeded, the block sheds to the next mode as defined by the block shed options. If ROut Timeout is set to 0, the block will not shed from ROut. Enter a positive value in the ROut Timeout field. Time duration is in 1/32 milliseconds (640000 = 20 secs).

Alerts

The DLC3020f provides two levels of alerts; Instrument alerts and PlantWeb alerts.

Instrument Alert Conditions

Instrument Alert Conditions, when enabled, detect many operational and performance issues that may be of interest. To view these alerts, the user must open the appropriate status screen on a host such as AMS Device Manager or a Field Communicator.

PlantWeb Alerts

Instrument alert conditions can be used to trigger PlantWeb alerts that will be reported in Failed, Maintenance or Advisory categories, as configured by the user. PlantWeb alerts, when enabled, can participate in the DeltaV alarm interface tools such as the alarm banner, alarm list and alarm summary.

When a PlantWeb alert occurs, the DLC3020f sends an event notification and waits a specified period of time for an acknowledgment to be received. This occurs even if the condition that caused the alert no longer exists. If the acknowledgment is not received within the pre‐specified time‐out period, the event notification is retransmitted. This reduces the possibility of alert messages getting lost.

DLC3020f alerts can be reported in the following categories.

Failed— indicates a problem with the DLC3020f that affects its operation. Immediate action is required for a Failed condition.

Page 32

DLC3020f Digital Level Controller

July 2012

Maintenance— indicates a problem with the DLC3020f that, if ignored, could eventually lead to its failure. Maintenance conditions require prompt action.

Advisory— indicates a minor problem with the DLC3020f. An advisory condition does not have an impact on the process or device.

No Category— the alert has not been categorized.

Suppress PlantWeb Alert— the alert is still evaluated by the DLC3020f, but, it does not report the status condition

through an instrument alert.

Full Calibration

Weight (Bench only)—Weight Calibration is a bench calibration where weights are used to simulate the different forces the device sees at the minimum and maximum levels. All configuration data is needed to perform a Weight calibration. Weights are suggested based on the current density values so that the two weights closely simulate the minimum and maximum points the device should see, or based on water for certain setups. These are suggested values only; you can enter other values if desired.

Note

The larger the difference in the weights, the better the calibration will be, provided that the unit is not on a mechanical stop.

Note

Ensure that the moment arm is not resting on a travel stop during the calibration process. Also, the weights tend to oscillate when placed on arm, so allow sufficient time for this to dissipate before capturing the points.

When complete, the torque rate or gain will be correct at the calibration temperature. After finalizing the installation a zero trim may be needed since a zero shift may take place when installing the device.

Two Point (Bench or Field)—A Two Point Calibration fully calibrates the device by observing the level/interface at two points. The two points must be at least 5% of the displacer length apart. All instrument configuration data is needed to perform a Two Point calibration. Use this method of calibration when the length/interface can be externally observed.

Min/Max (Bench or Field)—During the Min/Max Calibration torque rate gain and zero are computed by completely submerging the displacer in two different fluids (one of which may be air or vapor). All instrument configuration data is needed to perform a Min/Max calibration and must contain the correct values for displacer volume and driver rod length.

Simple Zero/Span (Field only)— for applications with relatively constant density and temperature conditions. Two points (separated by at least 5% of the displacer length) are captured in this calibration. Only the displacer length is needed to perform the Simple Zero/Span procedure. This calibration does not allow the use of Temperature Compensation

Note

When using Simple Zero/Span the device cannot be temperature compensated for fluids or torque tube. This calibration should only be used when the temperature and the process density do not away your process conditions get from the calibrated conditions.

change, otherwise an untrimmable error will occur the farther

Two Point Time Delay (Field only)—the Two Point Time Delay Calibration is a two point calibration in which the two points captured can be taken some time apart. The first point is captured and stored indefinitely until the second point is captured. All instrument configuration data is needed to perform a Two Point calibration.

Trim Current Calibration

Zero Trim—Zero trim is an adjustment to the current calibration. This adjustment assumes that the current torque rate is correct and the PV error is due to a shift in the zero position.

Gain Trim—Gain trim is an adjustment to the current calibration. This adjustment assumes that the zero point is correct and the PV error is caused by a torque rate change.

Default Gain—Default Gain is an adjustment to the current calibration. This adjustment requires you to set the default gain to the known torque tube rate.

 THE ENTITY CONCEPT ALLOWS INTERCONNECTION OF INTRINSICALLY SAFE APPARATUS TO ASSOCIATED APPARATUS NOT SPECIFICALLY EXAMINED IN SUCH COMBINATION. THE CRITERIA FOR INTERCONNECTION IS THAT THE VOLTAGE (Vmax or Ui), THE CURRENT (Imax or Ii), AND THE POWER (Pmax or Pi) OF THE INTRINSICALLY SAFE APPARATUS MUST BE EQUAL TO OR GREATER THAN THE VOLTAGE (Voc or Uo) AND THE CURRENT (Isc or Io), AND THE POWER (Po) DEFINED BY THE ASSOCIATED APPARATUS. IN ADDITION, THE SUM OF THE MAX UNPROTECTED CAPACITANCE (Ci) AND MAX UNPROTECTED INDUCTANCE (Li), INCLUDING THE INTERCONNECTING CABLING CAPACITANCE (Ccable) AND CABLING INDUCTANCE (Lcable), MUST BE LESS THAN THE ALLOWABLE CAPACITANCE (Ca) AND INDUCTANCE (La) DEFINED BY THE ASSOCIATED APPARATUS. IF THE ABOVE CRITERIA IS MET, THEN THE COMBINATION MAY BE CONNECTED.

 THE FISCO CONCEPT ALLOWS INTERCONNECTION OF INTRINSICALLY SAFE APPARATUS TO ASSOCIATED APPARATUS NOT SPECIFICALLY EXAMINED IN SUCH COMBINATION. THE CRITERIA FOR THE INTERCONNECTION IS THAT THE VOLTAGE (Vmax or Ui), CURRENT (Imax or Ii) AND POWER (Pmax or Pi), WHICH AN INTRINSICALLY SAFE APPARATUS CAN RECEIVE AND REMAIN INTRINSICALLY SAFE, CONSIDERING FAULTS, MUST BE EQUAL TO OR GREATER THAN THE VOLTAGE (Voc or Uo), CURRENT (Isc or Io), AND POWER (Po) LEVELS WHICH CAN BE DELIVERED BY THE ASSOCIATED APPARATUS, CONSIDERING FAULTS AND APPLICABLE FACTORS. IN ADDITION THE MAXIMUM UNPROTECTED CAPACITANCE (Ci) AND INDUCTANCE (Li) OF EACH APPARATUS (OTHER THAN THE TERMINATION) CONNECTED TO THE FIELDBUS MUST BE LESS THAN OR EQUAL TO 5 nF AND 10 uH RESPECTIVELY.

IN EACH SEGMENT ONLY ONE ACTIVE DEVICE, NORMALLY THE ASSOCIATED APPARATUS, IS ALLOWED TO PROVIDE THE NECESSARY ENERGY FOR THE FIELDBUS SYSTEM. THE VOLTAGE (Uo or Voc or Vt) OF THE ASSOCIATED APPARATUS HAS TO BE LIMITED TO THE RANGE OF 9 V TO 17.5 VDC. ALL OTHER EQUIPMENT CONNECTED TO THE BUS CABLE HAS TO BE PASSIVE, MEANING THAT THEY ARE NOT ALLOWED TO PROVIDE ENERGY TO THE SYSTEM, EXCEPT FOR A LEAKAGE CURRENT OF 50 uA FOR EACH CONNECTED DEVICE. SEPARATELY POWERED EQUIPMENT NEEDS A GALVANIC ISOLATION TO ASSURE THAT THE INTRINSICALLY SAFE FIELDBUS CIRCUIT REMAINS PASSIVE.

THE CABLE USED TO INTERCONNECT THE DEVICES NEEDS TO HAVE THE PARAMETERS IN THE FOLLOWING RANGE:

LOOP RESISTANCE R': 15 TO 150 ohms/km INDUCTANCE PER UNIT LENGTH L: 0.4 TO 1 mH/km CAPACITANCE PER UNIT LENGTH C': 80 TO 200 nF/km C' = C' LINE/LINE + 0.5' LINE/SCREEN, IF BOTH LINES ARE FLOATING OR C' = C' LINE/LINE + C' LINE/SCREEN, IF THE SCREEN IS CONNECTED TO ONE LINE. LENGTH OF SPLICE: <1 m (T‐BOX MUST ONLY CONTAIN TERMINAL CONNECTIONS WITH NO ENERGY STORAGE CAPABILITY) LENGTH OF SPUR CABLE: <30 m LENGTH OF TRUNK CABLE: <1 Km

AT EACH END OF THE TRUNK CABLE AN APPROVED INFALLIBLE TERMINATION WITH THE FOLLOWING PARAMETERS IS SUITABLE: R = 90 TO 100 ohms AND C = 0 TO 2.2 uF. NOTE, A BUILT‐IN TERMINATOR IS INCLUDED ON THE FIELD SIDE AND A SELECTABLE TERMINATOR IS AVAILABLE ON THE HOST SIDE.

THE NUMBER OF PASSIVE DEVICES CONNECTED TO THE BUS SEGMENT IS NOT LIMITED IN THE FISCO CONCEPT FOR INTRINSICALLY SAFE REASONS. IF THE ABOVE RULES ARE RESPECTED, UP TO A TOTAL LENGTH OF 1000 m (SUM OF THE LENGTH OF THE TRUNK CABLE AND ALL SPUR CABLES), THE INDUCTANCE AND CAPACITANCE OF THE CABLE WILL NOT IMPAIR THE INTRINSIC SAFETY OF THE INSTALLATION.

 INSTALLATION MUST BE IN ACCORDANCE WITH THE CANADIAN ELECTRICAL CODE (CEC) PART 1 AND ANSI/ISA RP12.6

 MAXIMUM SAFE AREA VOLTAGE SHOULD NOT EXCEED 250 Vrms

 RESISTANCE BETWEEN INTRINSICALLY SAFE GROUND AND EARTH GROUND MUST BE LESS THAN ONE OHM.

 LOOPS MUST BE CONNECTED ACCORDING TO THE BARRIER MANUFACTURER'S INSTRUCTIONS

 IF HAND‐HELD COMMUNICATOR OR MULTIPLEXER IS USED IT MUST BE CSA APPROVED WITH ENTITY PARAMETERS AND INSTALLED PER THE

MANUFACTURER'S CONTROL DRAWING

DLC3020f Digital Level Controller

July 2012

Instrument Description

The FIELDVUE DLC3020f digital level controller (figure 27) is a fieldbus communicating instrument used to measure liquid level or the level of interface between two liquids using displacement sensor technology.

W9954-1

In addition to the normal function of reporting process level PV, the DLC3020f, using FOUNDATION fieldbus protocol, gives easy access to information critical to process operation and will readily integrate into a new or existing control system. AMS Device Manager or the 475 Field Communicator can be used to configure, calibrate, or test the digital level controller.

The DLC3020f is also designed to directly replace pneumatic, analog, or HARTr transmitters/ controllers. It can be mounted on a wide variety of 249 cageless and caged level sensors as well as on other displacer type level sensors through the use of mounting adaptors.

249 Caged Sensors (see table 11)

D 249, 249B, 249BF, 249C, 249K, and 249L sensors side‐mount on the vessel with the displacer mounted inside a cage

outside the vessel.

249 Cageless Sensors (see table 12)

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.
