DLC3010 Digital Level Controller

DLC3010 Orientation
Mount the digital level controller 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 can 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 5. 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 5. To rotate the head,
remove the head flange bolts and nuts and position the head as desired.
Mounting the Digital Level Controller on a 249 Sensor
Refer to figure 2 unless otherwise indicated.
1. If the set‐screw in the access handle is driven against the spring plate, use a 2 mm hex key to back it out until the
head is flush with the outer surface of the handle (see figure 6) . Slide the access handle to the locked position 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). This clamp will
be re‐tightened in the Coupling portion of the Initial Setup section.
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.
