1. For mounting a digital level controller on a 249 sensor, secure the shaft extension to the sensor torque tube shaft
via the shaft coupling and set screws, with the coupling centered as shown in figure 2‐8.
2. Slide the access handle to the locked position to expose the access hole. Press on the back of the handle as shown in
3. Remove the hex nuts from the mounting studs.
4. Position the insulator on the digital level controller, sliding the insulator straight over the mounting studs.
5. Install 4 washers (key 78) over the studs. Install the four hex nuts and tighten.
6. Carefully slide the digital level controller with the attached insulator over the shaft coupling so that the access hole
is on the bottom of the digital level controller.
7. Secure the digital level controller and insulator to the torque tube arm with four cap screws.
8. Tighten the cap screws to 10 N
