Load supervision

3.4.1

Over current supervision

FC610 monitors over current condition of the connected load by issuing an alarm message.

The over current function in FC610 is designed for supervision purpose only and should not be
used to replace any over current protection device.

The over current threshold and hysteresis settings are a percentage value of the I

. An over

current event is detected when any of the measured phase current is above the threshold. An
alarm is triggered.

The alarm is cleared when the phase current returns to or below the value of threshold setting
minus the hysteresis.

Example.

The threshold is set as 110 % with the hysteresis 10 %.

An over current alarm is triggered in FC610 when phase A current rise to/above 110 % I

. When

phase A current returns below 110 %, the alarm continues. Only when current phase A drops
below 100 %, i.e. 110 % (threshold) minus 10 % (hysteresis), the alarm is reset.
