higher than 83°

PCU Error Status (Word 3)

Sensor Limit

**Not a valid state**

Stability Limit

Indicates that the above decks equipment is mis-pointed from its intended

target by more than 0.5°. (FCC Tx Mute Compliance)

AZ Reference Error

Indicates a failure to integrate one the reference inputs within the Azimuth

Stabilization Loop.

AZ Servo Limit

Indicates the current draw through the Azimuth Servo Amplifier (motor driver
PCB) has exceeded what is required during normal operation

LV Servo Limit

Indicates the current draw through the Elevation Servo Amplifier (motor driver

PCB) has exceeded what is required during normal operation

CL Servo Limit

Indicates the current draw through the Cross-Level Servo Amplifier (motor driver

PCB) has exceeded what is required during normal operation
