9.1.3 Indicators on power and segment terminals

Figure 9-1 Possible indicators on power and segment terminals

Diagnostics The following states can be read on power and segment terminals:

On terminals with fuses, the green UM or US LED indicates that the main or segment

voltage is present on the line side of the fuse, meaning that if the green LED is on,

there is voltage on the line side of the fuse. If the red E LED is also on, the fuse has

blown or is missing and no voltage is applied after the fuse.

If the red E LED is on and the green D LED is flashing at 2 Hz on terminals with fuse

and diagnostics, there is no voltage present after the fuse.

Thus, a blown fuse is indicated by both diagnostic indicators (E and D).
