OPERATION
The SMART NAVIGATOR sends the following information to the SMART CONTROLLER/RECEIVER.
3.3.1
P
RIORITY EVENTS
=
REPORT BY EXCEPTION
The SMART NAVIGATOR does report by exception within after an event was registered.
1. Fault
alarm:
Whenever a SMART NAVIGATOR senses an over-current, i.e. a fault on the overhead line; it
sends the notification “fault alarm”.
2. Fault classification (permanent fault or momentary fault):
Whenever a Smart Navigator has detected a fault it will decide after a predefined delay
whether this fault was a momentary fault or a permanent fault (Evaluation of post fault circuit
condition). A momentary fault is classified based on the decision that the fault has already
been cleared and the overhead line returned to normal status. A permanent fault is classified
as one which still exists. Depending on this decision, a SMART NAVIGATOR either sends
“permanent” or “momentary” fault information.
3. Low
battery:
Whenever a SMART NAVIGATOR detects that its battery is approaching its end-of-life it
sends the “Low Battery” information.
4. Test (FCI ON):
Activating the reed contact TEST with a magnet for >0,2s activates a local fault indication and
the SMART NAVIGATOR sends out a Radio Test Signal “FCI On”.
5. Reset (FCI OFF):
If the LED indication of the SMART NAVIGATOR stops either by current, time or manual (by
magnet) the SMART NAVIGATOR sends out a Reset signal (FCI off).
3.3.2
O
THER EVENTS
Other non priority events are not sent by exception. Therefore their status change will be notified
within the next 15 minute routine interval call or any earlier initiated communication:
1. Battery
changed:
A change of battery will be reported if total power is lost and routine was conducted as
described in the instructions.

A
NALOG DATA
In addition to event based fault identification, the SMART NAVIGATOR also can report analog
readings. Continuous Reporting is done based on a 15 minute routine call interval cycle.
1. Average load current: Average load current of last call interval (15 minute average)
2. Temperature: Temperature at SMART NAVIGATOR
