No. Name Application
POWER LED Operation indication:
ON (green): Normal operation (5 V DC output)
ON (red): DC power is input but the power supply module is faulty (5 V DC
error, overload, or internal circuit failure)
OFF:
– DC power not input, power failure (including momentary power failure
longer than the allowable momentary power failure period)
– blown fuse
ERR terminal
Error output (max. 24 V, 0.5 A)
When power supply is mounted on redundant power main base unit
(Q3RB): Turns on when the system on the redundant power main base unit
operates normally. Turns off (open) when
– the power supply module fails
– the DC power supply is not input
– a CPU module stop error (including a reset) occurs
– or the fuse is blown.
Turns off (open) when a stop error occurs in any of the CPU modules in a mul-
tiple CPU system.
When power supply is mounted on redundant power extension base unit
(Q6RB): Turns on when the power supply module operates normally
Turns off (open) when
– the power supply module fails
– the DC power supply is not input
– or the fuse is blown.
