P.21 – 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
E
controller is not installed on the ITALFARAD cabinet
N
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 cosø is within the range delimited by
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.
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 – Trip threshold for the capacitors overload protection (alarm A08), that will arise after
a integral delay time, inversely proportional to the value of the overload.
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.

these parameters, in AUT mode the device does not connect / disconnect steps
even if the delta-kvar is greater than the smallest step.
