Mounting the Digital Level Controller on a 249 Sensor
Refer to figure 2‐4 unless otherwise indicated.
1. If the set‐screw in the access handle (figure 2‐6) 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 locked position to expose
the access hole. Press on the back of the handle as shown in figure 2‐4 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 2‐4). 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.
4. Position the digital level controller so the access hole is on the bottom of the instrument.
5. Carefully slide the mounting studs into the sensor mounting holes until the digital level controller is snug against
the sensor.
6. Reinstall the hex nuts on the mounting studs and tighten the hex nuts to 10 N
S
m (88.5 lbf
S
in).
Mounting the Digital Level Controller for High Temperature Applications
Refer to figure 2‐8 for parts identification except where otherwise indicated.
The digital level controller requires an insulator assembly when temperatures exceed the limits shown in figure 2‐7.
A torque tube shaft extension is required for a 249 sensor when using an insulator assembly.
CAUTION
Measurement errors can occur if the torque tube assembly is bent or misaligned during installation.
