Scope of Manual
This instruction manual includes specifications, installation, operating, and maintenance information for the FIELDVUE
DLC3020f digital level controller.
This manual describes device setup using AMS Suite: Intelligent Device Manager version 10.5 and later. You can also
use the 475 or the 375 Field Communicator to setup the DLC3020f.
Note
This manual documents procedures in AMS Device Manager 10.5 and later. Earlier versions of AMS Device Manager contain the
same procedures and methods, but access is through the block in which they reside.
Do not install, operate, or maintain a DLC3020f digital level controller without being fully trained and qualified in field
instrument and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is
important to carefully read, understand, and follow all of the contents of this manual, including all safety cautions and
warnings. If you have any questions regarding these instructions contact your Emerson Process Management sales
office before proceeding.
Instrument Description
The FIELDVUE DLC3020f digital level controller is a fieldbus communicating instrument used to measure liquid level or
the level of interface between two liquids using displacement sensor technology.
In addition to the normal function of reporting process level PV, the DLC3020f, using F
OUNDATION fieldbus protocol,
gives easy access to information critical to process operation and will readily integrate into a new or existing control
system. AMS Suite: Intelligent 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 1‐7)
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 1‐8)
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.
Foundation Fieldbus Blocks
Instrument Blocks
The digital level controller is a block‐based device. For detailed information on the blocks within the digital level
controller, see the Parameter section.
