Global alarm

property arises.

NCA = Alarm normally energized. The relay is de-energized when any alarm with the

Global alarm

property arises.

FAN = The relay controls the cooling fan.
MAN = Relay is energized when device is in MAN mode.
AUT = Relay is energized when device is in AUT mode.
A01 ... A12= The relay is energized when the alarm specified is active.

If set to OFF, password management is disabled and anyone has access to the settings and commands menu.

P.22

With P.21 enabled, this is the value to specify for activating user level access. See Password access chapter.

P.23

As for P.22, with reference to Advanced level access. (*) Available value only if the controller is not installed on the ICAR cabinet

P.24

Number of phases of the power correction panel.

P.25

Enables the measurement of the actual power of the step, performed each time they are switched in. The measure is calculated, as the current
measurement is referred to the whole load of the plant. The measured power of the steps is adjusted (trimmed) after each switching and is
displayed on the step life statistic page. When this function is enabled, a 15 sec pause is inserted between the switching of one step and the
following, necessary to measure the reactive power variation.

P.26 – P.27 Tolerance around the setpoint. When the cos



is within the range delimited by these parameters, in AUT mode the device does not connect /

disconnect steps even if the delta-kvar is greater than the smallest step

P.28

Selecting mode of steps insertion.
Standard mode - Normal operation with free selection of the steps
Linear mode - the steps are connected in progression from left towards right only following the step number and according to the LIFO (Last In First
Out) logic. The controller will not connect a step when the system steps are of different ratings and by connecting the next step, the set-point value
would be exceeded.
Disc -

As in the Standard mode but with reduced time spent in capacitive

P.29

Setpoint used when the system is generating active power to the supplier (with negative active power / power factor ).

P.30

Disconnection sensitivity. Same as the previous parameter but related to disconnection. If set to OFF the disconnection has the same reaction time
of connection set with the previous parameter.

P.31

If set to ON, when switching from AUT mode to MAN mode, steps are disconnected in sequence.

P.32

Capacitors overload protection Trip threshold (alarm A07), that will arise after an integral delay time, inversely proportional to the overload value.
Note: You can use this protection only if the capacitors are not equipped with filtering devices such as inductors or similar.

P.33

Threshold beyond which the integral delay for tripping of the overload alarm is zeroed, causing the immediate intervention of the

A08

alarm.

P.34 – P.35 Data of VTs eventually used in the wiring diagrams.
P.36

Unit of measure for temperature.

P.37 – P.38 Start and stop temperature for the cooling fan of the panel, expressed in the unit set by P.36. The cooling fan is started when the temperature is

>= to P.37 and it is stopped when it is < than P.38.

P.39

Threshold for generation of alarm

A08 Panel temperature too high

P.41

Maximum voltage alarm threshold, referred to the rated voltage set with P.07, beyond which the alarm

A06 Voltage too high

is generated.

P.42

Undervoltage alarm threshold, referred to the rated voltage set with P.07, below which the alarm

A05 voltage too low

is generated.
