DLC3010 Digital Level Controller

CAUTION
When shipping an instrument mounted on a sensor, if the lever assembly is coupled to the linkage, and the linkage is
constrained by the displacer blocks, use of the lever lock may result in damage to bellows joints or flexure.
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, perform the Coupling procedure.
3. 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.
4. If the controller was shipped alone, the access handle will be in the locked position. All of the Mounting, Coupling
and Calibration procedures must be performed.
The access handle includes a retaining set screw, as shown in figures 2 and 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.
Hazardous Area Approvals and Special Instructions for “Safe Use” and
Installations in Hazardous Locations
Certain nameplates may carry more than one approval, and each approval may have unique installation/wiring
requirements and/or conditions of “safe use”. These special instructions for “safe use” are in addition to, and may
override, the standard installation procedures. Special instructions are listed by approval type.
Note
This information supplements the nameplate markings affixed to the product.
Always refer to the nameplate itself to identify the appropriate certification. Contact your Emerson Process Management sales
office for approval/certification information not listed here.
WARNING
Failure to follow these conditions of safe use could result in personal injury or property damage from fire or explosion, or
area re‐classification.
