P.61 A01 Alarm enable
P.62 A01 alarm delay
P.63 A01 delay UOM
... ....
P.97 A13 Alarm enable
P.98 A13 alarm delay
P.99 A13 delay UOM
P.61 – Enable alarm A01 and defines the behavior of the controller when the alarm is active:
OFF – Alarm disabled
ON – Alarm enabled, only visual
ALA – Alarm enabled, global alarm relay energized (if set)
DISC – Alarm enabled, logoff step if the controller is in automatic mode
A + D = Alarm relay energized and disconnection of the steps if the controller is in automatic mode.
Note: when you access the parameters P.61, P.64, P.67, etc., the auxiliary display shows the relative alarm code.
P.62 – Delay alarm A01.
P.63 – Unit of delay alarm A01.
P.64 – Like P.61 for alarm A02.
P.65 – Like P.62 for alarm A02.
P.66 – Like P.63 for alarm A02.
...
P.97 – Like P.61 for alarm A13.
P.98 – Like P.62 for alarm A13.
P.99 – Like P.63 for alarm A13.
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 DCRL8 depends on the properties settings of the active alarms.

ALARM EXPLANATION
In automatic mode, all the available steps are connected but the cosphi is still more inductive than the setpoint.
In automatic mode, all the steps are disconnected but the cosphi 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 occoured 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 either P.45 or P.54 has elapsed.
To reset the alarm see command menu.
The residual power of one or more steps is lower than minimum threshold set with P.40.
