P26.n.01
- Alarm enabled - General enabling of the alarm. If the alarm isn't enabled, it's as if it doesn't exist.
P26.n.02
- Retained alarm - Remains in the memory even if the cause of the alarm has been eliminated.
P26.n.03
- Operating mode – Operating modes where the alarm can be generated.
Global alarm 1 -2 -3
- Activates the output assigned to this function.
P26.n.04-05-06
- Step disconnection mode – Defines whether and how the capacitor steps must be disconnected when the alarm is present. OFF = no disconnection, SLOW =
gradual disconnection, FAST = Immediate disconnection.
P26.n.08
- Slave disconnection mode – Defines, for Master-Slave applications, if when this alarm arises, the disconnection is extended to all the step of the system (GENERAL) or
only to the output of the interested panel (LOCAL).
P26.n.09
- Inhibition - The alarm can be temporarily disabled by activating an input that can be programmed with the Inhibit alarms function.
P26.n.10
- Modem call - A modem is connected as configured in setup.
P26.n.11
- No LCD - The alarm is managed normally, but not shown on the display.
P26.n.12-13
- Delay time – Time delay in minutes or seconds before the alarm is generated.
22. 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 pop-up window showing the alarm indications will
disappear momentarily, to reappear again after a few seconds.
The red LED near the alarm icon on the front panel will flash when an alarm is active.
If enabled, the local and remote alarm buzzers will be activated.
Alarms can be reset by pressing the key
□
.
If the alarm cannot be reset, the problem that generated the alarm must still be solved.
In the case of one or more alarms, the behaviour of the 8BGA depends on the
properties
settings of the active alarms.

DESCRIPTION
A01
Undercompensation
All the available steps are connected but the cosphi is still more inductive than the
setpoint.
A02
Overcompensation
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 higher than maximum measuring range.
A05
Voltage too low
The measured voltage is lower than the threshold set with P17.14.
A06
Voltage too high
The measured voltage is higher than the threshold set with P17.13.
A07
Panel temperature too high
The panel temperature is higher than threshold set with P17.06.
A08
Capacitor current overload
The calculated capacitor current overload is higher than threshold set with P17.08
and/or P17.09.
A09
No-Voltage release
A no-voltage release has occoured on the line voltage inputs, lasting more than 8ms.
