6.2.4.5 VT fuse failure
This screen can be accessed at Actual> Status > Control Elements >VT Fuse Failure, and it includes only one LEDs for the
VT fuse failure function, indicating the activation of the unit.

6.2.4.6 Broken conductor
F650 units incorporate three Broken Conductor elements for special applications that may require different timing steps or
levels for alarm or trip purposes.
The green LED lights up when the pickup or trip (operation) of each of the three available functions is activated. The three
functions are identical and can be configured separately.
These functions compare the negative and positive sequence current levels per phase. If this magnitude exceeds a
programmable threshold and is maintained for a programmable time delay, a tripping output is issued. If a pickup or
operation is produced, the corresponding LED in this screen lights up.
This screen can be accessed at Actual> Status > Control Elements > Broken Conductor, and it includes the following
signaling LEDs for the breaker failure function:
