Led Display - Gira 5110 00 Product Documentation

4.2.3.3 LED display

The media coupler has a two-colour status LED. This LED displays device statuses in normal
operation and during commissioning or maintenance.
The following display functions have been implemented:
- LED lights red:
Programming mode is active. Programming mode is activated by pressing the
programming button or by using the ETS. Programming mode is deactivated after the
physical address has been successfully programmed, or is generally deactivated by a
device test (power failure, ETS programming process of the application program).
Programming mode is also deactivated automatically after 4 minutes if none of the above
events occurs.
- LED flashes slowly red:
Safe-state mode is active (see page 25).
- LED flashes red quickly (only in operation as media coupler):
Filter function has not been configured (filter table has no function). This display is
dependent on the parameter settings of the media coupler. If the parameter "Telegrams TP
-> RF group telegrams" and/or "Telegrams RF -> TP group telegrams" is configured to
"forward unfiltered" and the device is started up with this parameter setting, the status LED
flashes red quickly. This is a sign that the filter table has no function.
i This state should only be configured in a KNX installation within the context of system
commissioning. During normal operation of a KNX system after commissioning, it is always
recommended to activate the filter function of the group telegrams in both communication
directions. This is realised by the parameter settings "filter" (default setting) or "lock".
- LED flashes yellow:
This display function also depends on the parameter settings. The parameter "Function of
the yellow status LEDs" defines how the display acts (see parameter table).
- LED briefly changes between red and yellow:
Device test at a device restart after power is restored or after an ETS programming
process.
The priority of the described display functions is fixed. Programming mode has the highest
display priority. As a result, when programming mode is active, the red lighting of the status LED
overrides all other display functions.
Safe-state mode has the second-highest display priority. The slow red flashing of the safe-state
mode overrides the quick red flashing of the filter function display (third display priority) and this,
in turn, overrides the yellow status function (fourth display priority).
