Alarms - Icar 8BMA Notice D'utilisation

1.25 ALARMS

When the controller detects an abnormal siutation in the system, a flashing alarm code is
displayed. By pressing any key, the alarm viewing will be momentarily ignored to permit
the user to check all the measurements. If no key is pushed for 30 seconds and the alarm
conditions persist, the alarm code will be displayed once again.
Each alarm can cause diverse results such as the alarm relay tripping, the delayed or
immediate step disconnection, etc., according to the programmed property.
The property of each alarm can be changed (e.g. disabled, change the delay time or
result), by using a PC and the relative software (code A25060000000056), used for the
quick parameter set-up.
The following table indicates the alarm codes and the relative meaning of each along with
the default setting.

Note:
None of the above-indicated alarms are non-volatile.
In MANU mode the steps disconnection take splace in case of the A09 - No voltage
release alarm only.
A01 - Under compensation
Capacitors are all connected and cosφ is lower than the set-point value.
A02 - Over compensation
All capacitors are disconnected and cosφ is higher than the set-point value.
A03 - Low current
Current value is 2.5% lower than end-scale value. In automatic, the capacitors are
disconnected after 2 minutes of the alarm activation.
