Fault Isolator Module
SNIFFER is a comprehensive Graphical User Interface (GUI) that let you automate the commissioning and installation of a Loopdrive system with up to 256 LDB-units over a single RS485 connection.
Sniffer is not only visualizing the various commissioning procedures but also provide streamlined methods for fault-finding and device allocating without the direct need for a digital communication protocol over the 2-wire audio line’s. It fulfills the user’s needs and expectations by far.
Main operating window FIM
Settings and commands that are available from the various menu’s are:
Basic settings like:
General Fault Contact status
And special service functions such as:
Audio output switching
FIM Tracking mode
FIM-Tracking-Mode is one of the best features on LoopDrive. With a click on the button the system is instructed to activate the FIM’s in sequential order, tracking the number of FIM’s on both the PRIMARY (send) and SECUNDARY (return) line during first commissioning by measuring, registering and counting the inrush current.
Tracking-mode will generate a notifying signal when the loop is successfully closed and ready for operation. The total amount of FIM’s that were Tracked are shown in the information fields and stored with the corresponding LDB for later verification.
In case a faulty section in the line is detected during tracking-mode operation, the operator is notified and the exact location of the faulty section is listed by the number of the last successful initialized FIM on either Primary or Secondary side of the loop.
Sniffer app detects single and multiple twisting in cabling, providing the correct signal phase along entire loop.
