Instruction Manual	DLC3100 Digital Level Controller
D104213X012	July 2019

Section 1

Introduction and Specifications

Scope of Manual

This instruction manual is a supplement to the DLC3100 and DLC3100 SIS Quick Start Guide (D104214X012) that ships with every digital level controller. This instruction manual includes specifications, operating, and maintenance information for FIELDVUE DLC3100 and DLC3100 SIS digital level controllers.

Notes

The DLC3100 SIS is identified by a label affixed to the terminal box cover.

Unless otherwise noted, the information in this document applies to both DLC3100 and DLC3100 SIS. However, for simplicity, the DLC3100 model name will be used throughout.

This instruction manual supports the 475 Field Communicator with device description revision 1, used with DLC3100 instruments with firmware revision 1.0.9. You can obtain information about the process, instrument, or sensor using the Field Communicator. Contact your Emerson sales office to obtain the appropriate software.

Do not install, operate, or maintain a DLC3100 digital level controller without being fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you have any questions regarding these instructions, contact your Emerson sales office before proceeding.

Installation, Mounting and Electrical Connections, and Initial Configuration and Calibration using the Local User Interface

Refer to the DLC3100 and DLC3100 SIS Quick Start Guide (D104214X012) for installation and connection information, as well as initial configuration and calibration using the local user interface. If a copy of this quick start guide is needed contact your Emerson sales office or visit Fisher.com.

Conventions Used

This manual describes using the Field Communicator to configure and calibrate the digital level controller.

Procedures that require the use of the Field Communicator have the text path and the sequence of numeric keys required to display the desired Field Communicator menu.

Description

DLC3100 Digital Level Controller

DLC3100 digital level controllers (figure 2) are used with level sensors to measure liquid level, the level of interface between two liquids, or liquid density. Changes in level or density exert a buoyant force on a displacer, which rotates the torque tube shaft (see figure 3). 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. See the block diagram in figure 4.

Instruction Manual	DLC3100 Digital Level Controller
D104213X012	July 2019

Several operations with the DLC3100 can be performed using the Field Communicator. The digital level controller can be configured, calibrated, or tested. Using the HART protocol, information from the field can be integrated into control systems or be received on a single loop basis.

DLC3100 digital level controllers are designed to directly replace standard pneumatic and electro-pneumatic level transmitters. DLC3100 digital level controllers mount on a wide variety of caged and cageless 249 level sensors. They can also be mounted on other manufacturers’ displacer type level sensors with designed mounting kits.

CAUTION

There are many magnets used in the DLC3100 (lever assembly, push button, coupling handle). Care must be taken to avoid having a high powered magnet in close proximity. This could cause permanent damage to the DLC3100. Potential sources of damaging equipment include, but are not limited to: transformers, DC motors, stacking magnet assemblies.

General Guidelines for use of High Power Magnets:

Use of high power magnets in close proximity to any instrument which is operating a process should be avoided. Regardless of the instrument model, high power magnets can affect its functionality.

249 Caged Sensors

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

249BP, 249CP and 249P sensors top-mount on the vessel with the displacer hanging down into the vessel. 249VS sensor side-mounts on the vessel with the displacer hanging out into the vessel.

249W wafer-style sensor mounts on top of a vessel or on a customer-supplied cages.

Electrical Connections

Note

This information supplements the Electrical Connections section in the quick start guide (D104214X012) that shipped with your instrument. If a copy of this quick start guide is needed contact your Emerson sales office or visit Fisher.com.

Test 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.

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 mV.

3.Connect the positive lead of the test meter to the + connection and the negative lead to the TEST connection inside the terminal box.

4.Measure Loop current as mV = mA. For example, if the meter measures 12.5 mV, it means the loop current is 12.5 mA.

5.Remove test leads and replace the terminal box cover.

Alarm Conditions

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 trip alarm current either below 3.6 mA or above 21 mA, depending on the position (High/Low) of the alarm switch.

An alarm condition occurs when the 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 switch. The factory default Alarm Switch setting is High.

Refer to table 9 for alerts that will trigger the Trip Alarm Current when enabled.

Loop Test

Note

The DLC3100 must be put out of service during Loop Test. Place the loop into manual operation before putting device out of service as the DLC3100 output may not be valid.

When the DLC3100 is out of service, it is locked for exclusive access by the Primary/Secondary master that put it out of service. If the instrument reports Locked by HART or Access Restricted when you attempt to configure it, and a master of the original priority is not available, use Force Mode on the Local User Interface menu to force the instrument mode to In Service. You will then be able to take it out of service with your own master to make changes.

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 Test Connections procedure) or connect the meter in the loop as shown in figure 8.

2. Access Loop Test via Service Tools > Maintenance > Tests > Loop Test (3-4-2-2).

3.Select OK after you set the control loop to manual. The Field Communicator displays the loop test menu.

4.Put the instrument to “Not in Service” and select analog output level: 4mA, 20mA or Other to manually input a value between 4 and 20 milliamps.

5.Check the reference meter to verify that it reads the value that is commanded. 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 and put instrument back in service.

Section 4

Configuration and Calibration using AMS Device Manager or a Field Communicator

Note

Refer to the DLC3100 and DLC3100 SIS Quick Start Guide (D104214X012) for configuration and calibration using the local user interface. If a copy of this quick start guide is needed contact your Emerson sales office or visit Fisher.com.

DLC3100 has to be set to “Not In Service” during configuration and calibration which include:

D Device Setup

D PV Setup

D Process Setup

D Calibration

D Manual Setup

D Alert Setup

The DLC3100 will continue to regulate the current output based on lever assembly position. The output can be at failed current value (determine by alarm switch on the Main Electronics Board) depending on the device alerts/status. This current output shall not be treated as actual level/interface measurement as the device is “Not In Service”.

CAUTION

The control loop must be in manual before putting DLC3100 to Not In Service.

Note

When configuring the DLC3100 using the DD, the access of DLC3100 via Local User Interface will be locked.

If a DLC3100 digital level controller ships from factory mounted on a 249 sensor, initial setup and calibration may not be necessary. The factory enters the sensor data, couples the instrument to the sensor, and calibrates the instrument and sensor combination.

17

DLC3100 Digital Level Controller	Instruction Manual
July 2019	D104213X012

Note

If the digital level controller mounted on the sensor is received with the displacer blocked, or if the displacer is not connected, the instrument will be coupled to the torque tube assembly and the lever assembly unlocked. To place the unit in service, if the displacer is blocked, remove the rod and block at each end of the displacer and check the instrument calibration. (If the “factory cal” option was ordered, the instrument will be pre-compensated to the process conditions provided on the requisition, and may not appear to be calibrated if checked against room temperature with 0% and 100% water level inputs). If the displacer is not connected, hang the displacer on the torque tube.

If the digital level controller mounted on the torque tube arm and the displacer is not blocked when received (such as in skid mounted systems), the instrument will not be coupled to the torque tube assembly, and the lever assembly will be locked. To place the unit in service, couple the instrument to the sensor and unlock the lever assembly.

When the 249 assembly is properly connected and coupled to the digital level controller, establish the zero process condition and perform the Trim Zero procedure. The torque tube rate should not need to be recalibrated.

To review the configuration data entered by the factory, connect the instrument to a 24 VDC power supply as shown in figure 8. Connect the AMS Device Manager/Field Communicator to the instrument and turn it on. Go to Configure and review the data under Manual Setup and Alert Setup. If application data has been changed since the instrument was factory-configured, refer to the Manual Setup section for instructions on modifying configuration data.

Configuration Advice

Force Mode

Local User Interface Menu > Force Mode

When the DLC3100 is out of service, it is locked for exclusive access by the Primary/Secondary master that put it out of service. The same master must be used to put the instrument back in service; another master will not be able to change anything on the device and the LCD will return a “Locked by HART” message, unless you run Force Mode.

Select Force Mode to force the instrument mode to In Service if the original master is not available.

Note

Make sure no outstanding tasks are on-going in the device, including configuration and calibration, before forcing the DLC3100 In Service

Write Protection

To setup and calibrate the instrument, write protection must be set to disable.

Level Offset

Level Offset is the value DLC3100 reports when the process level is at the bottom of the displacer. Adding a level offset permits the process variable value in engineering units to be reported with respect to a reference point other than the bottom of the displacer. Examples include: bottom of the process vessel, the process set point, or sea level. Set Level Offset is only available in Level or Interface measurement mode. Follow the prompts on the Field Communicator to enter the offset value (2-3-2-1-6).

Level Offset will affect URV/LRV, PV Hi/Lo, PV HiHi/LoLo alerts. Changing PV alert points assumes you have already considered the affect of Level Offset on the alert points. This parameter should be cleared to zero before running Device Setup.

Initial Setup

Initial Setup consists of the following:

D Device Setup

D PV Setup

D Process Setup

All three setup procedures must be completed when configuring the DLC3100 in order for the device to function properly.

Initial Setup directs you through initialization of configuration data needed for proper operation. When the instrument comes out of the box, the default dimensions are set for the most common Fisher 249 construction. If any data is unknown, it is generally safe to accept the defaults. The mounting position - left or right of displacer - is important for correct interpretation of positive motion. Use Manual Setup to locate and modify individual parameters when they need to be changed. Refer to the Initial Setup section below for DLC3100 configuration.

Notes

The DLC3100 has to be “Not In Service” when carrying out Initial Setup. Place the loop into manual operation before putting device out of service as the output will not be valid.

When the DLC3100 is out of service, it is locked for exclusive access by the Primary/Secondary master that put it out of service. If the instrument reports Locked by HART or Access Restricted when you attempt to configure it, and a master of the original priority is not available, use Force Mode on the Local User Interface menu to force the instrument mode to In Service. You will then be able to take it out of service with your own master to make changes.

Guided setup is available to aid initial setup. Follow the prompts to enter information required by the setup. Most of the information is available from the sensor nameplate.

Device Setup

AMS Configure > Guided Setup > Device Setup

Field Communicator Configure > Guided Setup > Device Setup (2-2-1)

Input the required information as follows:

D Displacer Information (Length, Weight and Volume)

D Driver Rod Length (refer to table 11 and figure 9)

D Mounting Position (Left or Right of Displacer)

D 249 Sensor Model

D Torque Tube Material and wall thickness

The Driver Rod (moment arm) is the effective length of the driver rod length, and depends upon the sensor type. For a 249 sensor, refer to table 11 to determine driver rod length.

Once Device Setup is completed, configure the application settings using the PV Setup procedures.

PV Setup consists of the following:

D Measurement Application (Level, Interface or Density) (see table 12)

D Analog Output Action (Direct or Reverse)

D Level Offset

D Measurement Range (Lower Range Value and Upper Range Value)

Note

For interface applications, if the 249 is not installed on a vessel, or if the cage can be isolated, calibrate the instrument with weights, water, or other standard test fluid, in level mode. After calibrating in level mode, the instrument can be switched to interface mode, then enter the actual process fluid specific gravity and range values, follow with Trim Zero.

Table 12. Application Information

	Measurement Application	Description
		The default process variable units are set to the same units chosen for displacer length. When level
	Level, Interface	offset is changed, range values will be initialized based on level offset and displacer length. The default
		upper range value is set to equal to displacer length and the default lower range value is set to zero when
		the level offset is 0.
	Density	The default process variable units are set to “SGU” (Specific Gravity Units). The default upper range value
		is set to “1.0” and the default lower range value is set to ”0.1”.

When a DLC3100 with analog output is set for direct action the loop current will increase as the fluid level increases. Upper Range Value is the process variable values at 20 mA and Lower Range Value is the process variable values at 4 mA.

Choosing Reverse action will swap the default values of the upper and lower range values. The loop current will decrease as the fluid level increases. Upper Range Value is the process variable values at 4 mA and Lower Range Value is the process variable values at 20 mA.

Once PV Setup is completed configure the process information using the Process Setup procedures.
