Installation Troubleshooting
17-13
State
Description
PCU Status (Word 1)
Slow Scan
Indicates antenna is in a specialized mode, Slow Scan, which is required when
ever a test requires driving the antenna >5°/sec
Sat Reference
Indicates that satellite reference mode is enabled.
DishScan®
Indicates that DishScan® Drive is enabled.
Unwrap
Indicates that the antenna is currently in an “Unwrap” state.
This is not a valid error for unlimited azimuth antenna systems
Data 3
Indicates active communication between above decks and below decks
equipment at the time of query
Data 2
Indicates active communication between above decks and below decks
equipment at the time of query
PCU Status (Word 2)
Az Target
Indicates the antenna is currently targeting a pre-determined azimuth position
Az Velocity
**Not a valid state**
Valid Heading (PCU)
Indicates that the PCU has received and integrated the heading value from the
ACU into the Azimuth Stabilization Loop. This is NOT an indication of a proper
Heading integration into ACU.
PCU Error
Indicates that one or more errors have been reported by the above decks
equipment.
PCU Init
Indicates that the above decks equipment is currently performing an
Initialization sequence
Hi Elevation
Indicates that the above decks equipment is operating an Elevation Position
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
