The signaling outputs X
0
to X
3
and trip outputs X
4
and X
5
are all programmable type.
The factory default setting of the arrangement of these outputs is as shown in the internal function
block diagram of Figure 5.2. This setting can be freely changed by specifying outputs of the internal
elements based on the OR logic.
All the outputs
have been set to “auto reset” in the factory. Any of them can be changed to “self hold”.

(5) Forced
operation
It is possible to carry out forced operation of any of the signaling outputs X
0
to X
3
and trip outputs X
4
and X
5
independently. Forced operation is useful for checking the wiring.
When forced operation is carried out, the corresponding LED lamps will come on to show the current
status of the programmable outputs. Checking the lamp status will be useful not only for wiring check
but also to check the programmable outputs arrangement.
