Alarms 

 

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 DCRL depends on the 

properties

 settings of the active alarms.

 

 

 

 
Alarm description 

 

 

ALARM 

DESCRIPTION 

A01 

Undercompensation 

In automatic mode, all the available steps are connected but the cosphi is 
still more inductive than the setpoint. 

 

A02 

Overcompensation 

In  automatic  mode,  all  the  steps  are  disconnected  but  the  cosphi  is  still 

more capacitive than the setpoint.

 

A03 

Current too low 

The current flowing in the current inputs is lower than minimum measuring 

range.

 

This condition can occour normally if the plant has no load.

 

A04 

Current too high 

The current flowing in the current inputs is lower than minimum measuring 

range.

 

A05 

Voltage too low 

The measured voltage is lower than the threshold set with P.42.

 

A06 

Voltage too high 

The measured voltage is higher than the threshold set with P.41.

 

A07 

Capacitor current  overload 

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.

 

A08 

Temperature too high 

The panel temperature is higher than threshold set with P.39.

 

A09 

No-Voltage release 

A no-voltage release has occoured on the line voltage inputs, lasting more 
than 8ms.

 

A10 

Voltage THD too high 
 

The THD of the plant voltage is higher than the threshold set with P.43.

 

A11 

Current THD too high 

The THD of the plant current is higher than the threshold set with P.44.

 

 

 

 

A12 

Maintenance requested 

The  maintenance  interval  set  with  P.45  has  elapsed.  To  reset  the  alarm 
use the command C.01 (see Command menu).

 

A13 

Step failure 

The residual power of one or more steps is lower than minimum threshold 

set with P.40.
