Red On No fuse, or tripped fuse
Off Fuse okay
Fig. 9-30: Additional LED for supply terminals with fuse
Note: In modules with fuse, the green LED indicates that the main or
segment voltage is available upstream of the fuse. That
means that, with the green LED being lit, the voltage is applied
upstream of the fuse. If the red LED is lit as well, the voltage is
not applied to the output side! Either there is no fuse, or the
fuse is defective.
