1.
Verify that there is at least one point in the Open Processor.
2.
Disconnect the FLN 1 Trunk cable that connects the Open Processor to the Trunk
Interface II to see if the problem disappears. If the LEDs start flashing, the wiring
may be bad. Check the wiring polarity between the Trunk Interface II and the Open
Processor: + to +, – to –, shield connected at the Open Processor, but
disconnected at the Trunk Interface II.
3.
Contact your local Siemens Building Technologies representative.
