Diagnosis of error points in the various protection-circuit (P.D. circuits) operations (Red "STANDBY/ON" LED blinks)
Note on PS PD
The condition that Red "STANDBY/ON" LED
blinks five times (power supply PD)
1 When the internal protection circuit of the
SW POWER SUPPLY Module worked
2 When a microcomputer was not able to
identify the PD point
↓
Care must be taken because five blinks of
the red LED does not always mean that the
protection circuit of the SW POWER SUPPLY
Module is activated.
