Tab. 11: Status of the TFLN LEDs in full-working conditions 
 
 
2.  About 10 seconds after the system has been switched on, TFLN module begins a “discovery” 
phase to identify connected remote units. This operation is necessary to collect all the 
information to be provided to the supervision system. 
While the discovery phase is working, the TFLN general alarm (LED 
┌┘
) blinks while the 
other LEDs go on showing previously detected status. Time dedicated to discovery phase can 
be at maximum 4min and depends on system complexity.  Do not connect/disconnect any 
cable or any piece of equipment during the discovery phase!
 This may result in failing the 
identification of remote units. 
Please note that, while the discovery phase is running, the whole system is working correctly. 
Discovery operations aim to collect information about remote units but they don’t affect the 
system functionality. 
 
3.  Once the discovery is finished, the TFLN general alarm (LED ┌┘) stops blinking and switches 
OFF. The power supply LED (green LED) remains on while LEDs 1,2,3,4 show either the 
status of the remote units or the quality of the UL connections. In case some of these LEDs 
remain on, check if they refer to unused optical ports or not. In case of unused TFLN ports use 
LMT to mask it otherwise if LED referring to a connected remote unit remains on, please refer 
to Troubleshooting procedure. 
 
 
Removing a TFLN module 
 
Switch off the Master Unit power supply, remove the SC-APC optical connectors, and insert the 
protection caps into TFLN optical ports. Then  
•  unscrew the 4 screws and slowly remove the card. 
•  put the removed TFLN card in its safety box. 
• 
switch on again the Master Unit power supply, and refer to Start Up section.
