STATUS
ERROR LLLL RRRR
Status – Error menu.
LLLL - Comms Error Count - indicates the
number of times that a Pedestal M&C
communication message (between the ACU and
PCU) was not received correctly. Occasional
counts are normal but more than 10 per minute
indicates a problem that needs attention (refer
to Troubleshooting section).
RRRR - Error Code - indicates the SUM of
the discrete error(s) that have occurred. It does
not indicate
how many of a particular error have
occurred. Refer to the “To View Errors”
paragraph below for a complete list of the
discrete errors which could occur.
Pressing UP arrow key clears error count, status
code and extinguishes the Error LED.
STATUS
REMOTE AUX 0000
Status – Remote Aux menu. Diagnostic
display of Remote auxiliary read, typically used
to indicate Temperature or EIRP readings from
the antenna.
Continuing to press MODE will not advance the
display until the correct password is entered to
allowing entry into the SETUP Parameter menus.
To access the SETUP Parameters, key in the
password “7979” and press the

2.5.5. SETUP Parameter display and entry menus.
Access to the password protected system setup parameters is only required during installation or
repair of your antenna system. These parameters should only be changed by an authorized service
technician.
CAUTION
: Improper setting of these parameters will cause your system to not to perform
properly.
Refer to the SETUP information in the Installation section of this manual.
2.6. Tracking Operation
You can toggle Tracking ON/OFF by simply pressing the AUX1 key.
Tracking optimizes the pointing of the antenna, in very fine step increments, to maximize the level of the
satellite signal being received. DishScan is the
default mode of tracking.
2.6.1. DishScan Operation
This system uses a variation of Conical scanning, called DishScan, which continuously drives the
antenna in a
very small diameter circle at 60 RPM. The received signal is evaluated throughout
each full circle rotation of the antenna to determine where the strongest signal level is and will issue
the appropriate Azimuth and/or Elevation steps to the antenna, as needed, 60 times per minute.
When you are in the AZIMUTH or ELEVATION entry menu, the DishScan commands (2, 4, 6 or 8)
will be visible in the lower left corner of the display. A 2 = DOWN, 4 = LEFT, 6 = RIGHT and 8 = UP.
When Tracking is turned
OFF these commands indicate movement direction that is needed, but the
commands will not be issued to the antenna to actually re-position it. Tracking must be turned
ON to keep the antenna peaked on the satellite.
