ERROR MESSAGES
"NO ROOM" - Denotes that the satellite non-volatile memory space is full - in order to enter a
new satellite, one must be deleted. When this message appears the user may reset the data for
a satellite name that is already in memory.
"CW/CCW SKEW LIMIT" - The polarotor probe has reached a limit and cannot be adjusted
any further in that direction.
"E/W LIMIT" - The antenna is at a polar axis software limit and cannot be moved any further in
that direction.
"LOW BATTERY" - Denotes that the battery needs to be replaced.
"NO DATA" - Denotes the memory is clear.
"AZIM COUNT ERROR" - The value for the position count, stored in memory, is corrupted.
This generally occurs in one of three possible ways.
1.
The battery backup supply is too low to retain the SRAM memory - replace battery.
2.
On initial power-up at the factory before the SRAM is cleared.
Should either of these cases occur, the unit needs to be reprogrammed.
3.
If the antenna is moving when power is disconnected. This may or may not cause the
problem.
The user should implement the FIX mode, section 6-8, if case 3 occurs.
"ANT/SENSOR ERROR" - The unit senses no feedback from the position sensor while the
drive signals are present. The RC1000A will shut down if this occurs for two seconds. Check the
sensor or antenna for a jammed condition.
"INVALID" - This message can occur in AUTO mode. It means the selected satellite position
resides outside the software limits and the unit ignores the move command. Check to see if
LIMITS have been altered.
