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.
