4. If the controller was shipped alone, the access handle will be in the locked position. All Mounting, Coupling and
Calibration procedures must be performed.
The access handle includes a retaining set screw, as shown in figures 2‐4 and 2‐6. The screw is driven in to contact the
spring plate in the handle assembly before shipping. It secures the handle in the desired position during shipping and
operation. To set the access handle in the open or closed position, this set screw must be backed out so that its top is
flush with the handle surface.

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.
Hazardous Area Classifications and Special Instructions for "Safe Use" and
Installations in Hazardous Locations
Refer to the DLC3010 Quick Start Guide (D103214X012) that ships with the instrument for Hazardous Area
Classifications and Special Instructions for "Safe Use" and Installations in Hazardous Locations. If a copy of this quick
start guide is needed contact your

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 figure 2‐2. If the sensor has a cageless
displacer, the sensor mounts on the side or top of the vessel as shown in figure 2‐3.
The DLC3010 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.
