P26.n.10 Modem call
P26.n.11 Not shown on LCD
P26.n.12 Alarm delay
P26.n.13 Delay UoM
P26.n.01 - Alarm enabled - General enabling of the alarm. If the alarm is not enabled, it is 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.

21 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
All the available steps are connected but the cosphi is still more inductive than the setpoint.
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 higher than maximum measuring range.
The measured voltage is lower than the threshold set with P17.14.
The measured voltage is higher than the threshold set with P17.13.
The panel temperature is higher than threshold set with P17.06.
The calculated capacitor current overload is higher than threshold set with P17.08 and/or
P17.09.
A no-voltage release has occurred on the line voltage inputs, lasting more than 8ms.
The RMS current measured by the MCP5 module n is higher than threshold set with
P18.n.06.
The current THD measured by the MCP5 module n is higher than threshold set with
P18.n.07.
The percentage of 5.th harmonic content measured by MCP5 module is higher than threshold
set with P18.n.08.
The percentage of 7.th harmonic content measured by MCP5 module is higher than threshold
set with P18.n.09.
The percentage of 11.th harmonic content measured by MCP5 module is higher than
threshold set with P18.n.10.
The percentage of 13.th harmonic content measured by MCP5 module is higher than
threshold set with P18.n.11.
The temperature 1 measured by the MCP5 module is higher than threshold set with
P18.n.12.
The temperature 2 measured by the MCP5 module is higher than threshold set with
P18.n.13.
The slave nr. X does not communicate with the master. Check the RS-485 wiring.
Clean the air intake filter of the ventilation system.
Check the currents for each step, the efficiency of the fuses and contactors.
Perform the operations in A20 and A21 and check the capacitors conditions or contact
technical support.
Perform the control of mechanical and electrical contactors.
User-defined alarm, as specified by parameters of menu M25.
