Note
Sequence condition not fullled
1) For a sequence error from the initiation to the transition phase of the muting operation, only
the LED of the rst energized muting sensor that should not have been energized will ash.
2) For a sequence error from the transition phase to the end of the muting operation, only the
LED of the rst muting sensor that should have been de-energized, but is still energized, will
ash. In this phase, the muting direction is always known, i.e. in this phase, only one muting
sensor LED can ash due to a sequence error.
3) During paired sequence monitoring of the muting sensors, both input LEDs of the energized
muting sensor pair are ashing. In the event that only one muting sensor of a muting sensor pair
is energized, it cannot exist as a sequence error, because this would lead to a discrepancy error.
7.3.3.12 Output functions
The table below lists all the messages and corresponding LED responses to the "standard output"
and "F output" function elements.
Message Meaning LED response
SF-LED on central unit Input LEDs on central unit or
expansion module
Output x active Function output 1 is switch‐
ed on.
‑ ‑
Feedback circuit signal and
switching status do not
match
The signal at the feedback
circuit input does not match
the switching status of the
function outputs.
The output function imme‐
diately deactivates all its out‐
puts in case of inconsisten‐
cies.
red The corresponding IN LED of the
sensor ashes green if there is
no more than one negation be‐
tween the element input and
the input cell in the logic.
Start condition not fullled is set if:
• there is a feedback cir‐
cuit error when feed‐
back circuit monitoring
is activated.
• the value "0" is pending
at the function input
(IN).
