ILLUSTRATIONS REQUIRED:

Reference: Synchro Resolver Simulator Retrofit Kit, PN 93006N2800 and figures 1 and 2.

MODIFICATION PROCEDURE:

1. Shutdown test station per shutdown procedures.

2. Remove cover assembly 93006A2120 from the 93006A2000 chassis.

3. Disconnect all cables connected to the secondary chassis cover assembly 93006A2120.

4. Remove blank panel 93006A1114 from the VXI chassis slot number 12.

5. Ensure the Synchro/Resolver plug-in unit (93006H2800) dip switch positions are set as shown in figure 1.

6. Install the Synchro/Resolver plug-in unit into VXI Chassis slot 12.

7. Refer to figure 2. Attach shielding gasket (93006H1132-3) and cable assembly (93006H2916) to the cover assembly (93006N2113) using supplied hardware.
