Possible Cause: The rotary scale or rotary scale cable is faulty.
Make sure the cables are connected correctly.
Inspect the rotary scale cables for wear or damage.
Inspect the internal rotary scale cable interface cable, slightly pull on the wires to make sure they have a good crimp. If the cables are connected correctly and not damaged, and the alarm persists, the rotary unit needs to be serviced.
