Installation
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.

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 locked (exposing the coupling hole), it
positions the lever assembly 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 DLC3100 controller will have one of the following mechanical configurations when received:
D A fully assembled and coupled caged‐displacer (sensor) system shipped with the displacer or driver rod blocked
within the operating range by mechanical means. In this case, the coupling access handle (figure 2) will be in the

unlocked position (coupling hole is covered). Remove the displacer‐blocking hardware before calibration. Refer
to 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 torque tube assembly, and the
displacer is secured by movement blocks, use of the lever lock may result in damage to the lever assembly flexure.
D 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. The coupling access handle will be in the locked position.
Before placing such a configuration into service, perform the Coupling procedure.
D 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.
D If the digital level controller was shipped alone, the access handle will be in the locked position. Perform the
Mounting, Coupling and Calibration procedures.
Mounting the DLC3100
DLC3100 Orientation
Mount the digital level controller with the torque tube assembly coupling access hole (the coupling access handle in
figure 2) pointing downward.
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 3. This can be changed in the field on a 249 sensor (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 3. To rotate the head,
remove the head flange bolts and nuts and position the head as desired.

On a 249 Sensor in Extreme Temperature Applications
The digital level controller requires an insulator assembly when temperatures exceed the limits shown in figure 5.
A torque tube shaft extension is required for a 249 sensor when using an insulator assembly (see figure 6).
1. Mount the DLC3100 on a 249 sensor by securing the shaft extension to the sensor torque tube shaft via the shaft
coupling and set screws, with the coupling centered as shown in figure 6.

Coupling
If the digital level controller is not already coupled to the sensor, perform the following procedure.
1. Press the knob on the coupling access handle, shown in figure 2, then slide the handle towards the front of the
DLC3100 to expose the access hole and lock lock the lever assembly in place. Be sure the locking handle drops into
the detent; the DLC3100 LCD will display “Lever Locked”.
2. If in the actual process condition, set the displacer to the lowest possible process condition (lowest fluid level for
level application, or fill with fluid with minimum specific gravity for interface application). If on the bench, ensure
the displacer is dry and the displacer rod lever arm is not hitting a travel stop. Alternatively, the heaviest calibration
weight can be used to replace the displacer to simulate the dry displacer condition.
Note
Interface or density applications with displacer/torque tube sized for a small total change in specific gravity are designed to be
operated with the displacer always submerged. In these applications, the torque rod is sometimes resting on a stop while the
displacer is dry. The torque tube does not begin to move until a considerable amount of liquid has covered the displacer. In this
case, couple with the displacer submerged in the fluid with the lowest density and the highest process temperature condition, or
with an equivalent condition simulated with calculated weights.
If the sizing of the sensor results in a proportional band greater than 100% (total expected rotational span greater than
4.4 degrees), couple the transmitter to the pilot shaft while at the 50% process condition to make maximum use of available
transmitter travel (±6_). The Trim Zero procedure can be performed at the zero buoyancy (or zero differential buoyancy)
condition.
3. 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).
4. Press the knob on the coupling access handle, shown in figure 2, then slide the handle towards the rear of the unit
to unlock the lever assembly. Be sure the locking handle drops into the detent; “Lever Locked” on the DLC3100 LCD
will be cleared.

Electrical Connections
WARNING
Select wiring with temperature rating of > 85°C 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.
Proper electrical installation is necessary to prevent errors due to electrical noise. A resistance between 230 and 600
ohms must be present in the loop for communication with a Device Communicator. Refer to figure 7 for current loop
connections.
Figure 7. Connecting a Device Communicator to the Digital Level Controller Loop
A Device Communicator may be
connected at any termination
point in the signal loop other
than across the power supply.
Signal loop must have between
230 and 600 ohms load for
communication.

To communicate with the digital level controller, minimum 17.75 VDC power supply is required. The power supplied
to the transmitter terminal 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 8 to
determine the required lift‐off voltage.

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
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. The conductor size shall be of the range
16-24 AWG. 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 (see figure 9).
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.

CONNECTIONS
COMM TERMINALS
The digital level controller operates 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
To achieve EMC immunity, the recommended grounding techniques for shielded wire usually call for dual grounding
points for the shield. The shield can be connected at the power supply and the grounding terminals (internal or
external at the instrument terminal box, shown in figure 9).
Power/Current Loop Connections
Use ordinary copper wire of sufficient size to ensure that the voltage across the digital level controller terminals does
not go below 12.0 volts DC. Connect the current signal leads as shown in figure 7. After making connections, recheck
the polarity and correctness of connections, then turn the power on.
RTD Connections
An RTD that senses process temperatures may be connected to the digital level controller. This permits the instrument
to automatically make density corrections for temperature changes. For best results, locate the RTD as close to the
displacer as practical. For optimum EMC performance, use shielded wire no longer than 3 meters (9.8 feet) to connect
the RTD. Connect only one end of the shield. Connect the shield to either the internal ground connection in the
instrument terminal box or to the RTD thermowell. Wire the RTD to the digital level controller as follows (refer to
figure 9):
Two‐Wire RTD Connections
1. Connect a jumper wire between the RS and R2 terminals in the terminal box.
2. Connect the RTD to the R1 and R2 terminals.
