3rd tandem PF-703 cooling fan power abnormality.
The EM error detection signals of the FM19 and the FM20 are detected twice in succession within a period of time after the PF cooling fan /1 (FM19) and the PF cooling fan /2 (FM20) were activated. At this time, an error detection signal (blowout of ICP) is also detected.

- PF drive board (PFUDB)
Correction:
Turn OFF/ON the power switch (SW2) of the main body when releasing an abnormal condition.

Solution:
- Check the connector connection and the wiring between PFUDB and the fan, and repair it if any abnormality.
- Rotate the fan with I/O or by hand, and repair or replace it if there is any abnormality. (Wiring diagram: PF-703: 22-F, 23-F).
