Fault Resets

After the fault is reset, the device LEDs stops flashing and the phase-current measurements start again and the
device is ready for detecting the new faults. The faults detected by the device can be reset with the following
methods.
•
Voltage restoration
•
Auto reset timer
•
Magnetic reset
Voltage Restoration
If the voltage-based reset is enabled via SICAM FSI Configurator, the device monitors for the voltage restored
on the MV overhead line. When the device detects the line voltage presence, it resets the fault indication and
starts the new measurements again.
In order to avoid wrong resets, the device monitors the voltage presence for the time equal to the PFVT
configured for the device. If PFVT is disabled, the device monitors the voltage presence for 1 s.

Auto Reset Timer
The auto reset is enabled based on the configured fault-indication time set via the SICAM FSI Configurator.
The auto reset time can be configured from
•
B-Sensor Type 1: 2 h to 16 h (steps of 1 h)
•
B-Sensor Type 2: 2 h to 4 h (steps of 1 h)
The device resets the fault indication and starts new measurements on expiration of the fault-indication time.
Magnetic Reset
The fault indications can be cleared manually by touching the magnet adaptor to the device transparent cover
for approximately 1 s.
By using the magnetic reset, the device does a self test by flashing all the board LEDs in sequence 10 times
each.
