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, couple the instrument to the sensor as follows:
a. Slide the access handle to the open position to lock the lever assembly in place and 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.
b. If in process, ensure that the level or interface is in the lowest position on the displacer.
c. If on the bench, ensure that the displacer is dry and the displacer rod lever arm is not hitting a travel stop.
d. 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).
e. Slide the access handle to the closed position. for operation or calibration. (Press on the back of the handle as
shown in figure 2 then slide the handle toward the rear of the unit.) Be sure the locking handle drops into the
detent.
