Installation
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.

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.

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.

5. Carefully slide the mounting studs into the sensor mounting holes until the digital level controller is snug against
the sensor mounting flange.
6. Reinstall the hex nuts on the mounting studs and tighten the hex nuts to 10 NSm (88.5 lbfSin).
Mounting the DLC3020f for High Temperature Applications
Refer to figure 7 for parts identification except where otherwise indicated.
The digital level controller requires an insulator assembly when temperatures exceed the limits shown in figure 6.
A torque tube shaft extension is required for a 249 sensor when using an insulator assembly.

Electrical Connections
The following describes how to make fieldbus connections to the digital level controller.
WARNING
To avoid personal injury resulting from electrical shock, do not exceed the maximum input voltage specified in table 8 or on
the product nameplate. If the input voltage specified differs, do not exceed the lowest specified maximum input voltage.
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.
Personal injury or property damage caused by fire or explosion may occur if this connection is attempted in a potentially
explosive atmosphere or in an area that has been classified as hazardous. Confirm that area classification and atmosphere
conditions permit the safe removal of the terminal box cover before proceeding
Fieldbus Connections
The digital level controller is normally powered over the bus from a fieldbus 9 to 32 volt power supply and can be
connected to the segment using field wiring. Refer to the site preparation guide for proper wire types, termination,
length, etc. for a fieldbus segment.
Note
As shipped from the factory, the DLC3020f will have the transducer block mode set Out of Service. See the Configuration section
for information on setup and calibration and placing the instrument in service. The initial value for all blocks are shown in the
parameter list for each block in the Blocks section.
