Leveling Head Reassembly Procedure
Use the following procedure to reassemble the A9 Leveling head. See Figure 7-9.
1.
Make sure the cable is connected to the PCA. If not, make the connection as
described in the following steps, a through c:
a.
Position the cable in the correct orientation.
b. Connect the SMA connectors, and, while holding the SMA connector on the
PCA with an open-ended spanner, torque the connection to 1.0 Nm (8.86 in-lb).
c. Connect the 18-pin connector to the PCA.
2. Position the PCA in the bottom case. Make sure the cable grommet is correctly
positioned in the case.
3. Push the N-type connector plate gently back to mate with the case.
4. Secure the N-type connector to the bottom case with the two countersunk screws and
torque them to 0.25 Nm (2.22 in-lb).
5. Position and align the cable clamp with the screw holes in the bottom-half of the
