a) push RESET button on the FIM module
or
b) send REMOTE FIM RESET command by pressing RESET button on LDB for 10 seconds or via Sniffer
application.
5.3. Open T-Branch
If 47kΩ EOL resistor on T-Branch is missing, FIM with EOL monitoring will detect T-Branch open. In this case both A
and B indicators will blink fast orange alternately with 2 seconds intervals. Both relays of the FIM are open, creating
an interruption in the loop. T-Branch is isolated from the loop.
Picture 20. Open T-Branch
What to do?
Reconnect the T-Branch line to FIM, including 47kΩ EOL resistor. When the problem is fixed, the fast blinking
indication on FIM will turn slow. Now you can reset FIM to QUIESCENT mode, where both A and B relays are closed.
To reset FIM:
a) push RESET button on the FIM module
or
b) send REMOTE FIM RESET command by pressing RESET button on LDB for 10 seconds or via Sniffer
application.
