After installation is complete, if one or more of the resolvers is counting backward or if electrical zero is almost 180E out of phase, perform one of the following tasks.

1.Reverse S2 and S4 (SIN) leads to reverse direction without shifting electrical zero.

2.Reverse S1 and S3 (COS) leads to shift electrical zero and reverse direction.

3.Reverse R1 and R2 (REF) leads to shift electrical zero 180°. Direction remains the same.

2.4Display Offset Adjustment

The elevation, azimuth, and polarization readout angle may be adjusted with the digital switches inside the 7122B/7133B ACU using the following procedures.

1.Remove the top cover and locate the six 8-bit digital DIP switches (four on the 7122B) on the binary/BCD board, mounted to the left side of the chassis.

2.The offset switches are labeled AZ (S1 and S2), EL (S3 and S4), and POL (S5 and S6). Switches 1 and 2 are not used on DIP switches S1, S3, and S5. Switch 3 on DIP switches S1, S3, and S5 controls the most significant bit (180°) and switch 8 or DIP switches S2, S4, and S6 controls the least significant bit (0.022°). Set the switches to obtain the desired display angles.

3.To intentionally blank an axis, set the 16 switches as follows: (MSB)1010101010101010(LSB)

4.Replace the top cover.
