2. After fan motor restarts, if fan motor cannot operate at 470rpm or more,
or the same operation is repeated consecutively 3 times within 60 minutes,
fan motor and compressor stops permanently.
Check the appearance and condition of mounting of Driver PCB.
Change Driver PCB and release the error. Refer to the service parts info 5
Check if the error reoccurs on a test run.
After fixing the problem and for canceling the Error, Error Reset (F3-40) will be required after power reset
Caution
By changing of DIP SW 4-2 to ON, the Back-up operation can start when the active outdoor unit exists on the multi outdoor unit connection.
(Stand alone outdoor unit is impossible)
The following conditions will be concerned in use of back-up operation. (Please do not use the system with back-up operation for long time.)
- The operating compressor life time becomes shorter.
- The operating performance may drop due to the limited active compressor(s).
- The compressor may stop frequently by protection controlling.
*In order to keep the operating capacity, the release of the Low noise mode setting might be necessary.
