Alarms - ITALFARAD PFC144evo Manual De Uso


When an alarm is generated , the display will show an alarm icon, the code and the description of the alarm in the
language selected.

If the navigation keys in the pages are pressed, the scrolling message showing the alarm indications will disappear
momentarily, to reappear again after 30 seconds.

Alarms are automatically resetted as soon as the alarm conditions that have generated them disappear.

In the case of one or more alarms, the behaviour of the PFC144evo regulator depends on the properties settings of
the active alarms.

DESCRIPTION
In automatic mode, all the available steps are connected but the cosø is still more
inductive than the setpoint.
In automatic mode, all the steps are disconnected but the cosø is still more
capacitive than the setpoint.
The current flowing in the current inputs is lower than minimum measuring range.
This condition can occour normally if the plant has no load.
The current flowing in the current inputs is lower than minimum measuring range.
The measured voltage is lower than the threshold set with P.42.
The measured voltage is higher than the threshold set with P.41.
The calculated capacitor current overload is higher than threshold set with P.32
and P.33. After the alarm conditions have disappeared, the alarm message
remains shown for the following 5 min or until the user presses a key on the front.
The panel temperature is higher than threshold set with P.39.
A no-voltage release has occurred on the line voltage inputs, lasting more than
8ms.
The THD of the plant voltage is higher than the threshold set with P.43.
The THD of the plant current is higher than the threshold set with P.44.
The maintenance interval set with P.45 or P.54 has elapsed. To reset the alarm
see Command menu.
