Icar RPC 5LGA Notice D'utilisation page 31

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 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 cosϕ 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 – Trip threshold for the capacitors overload protection (alarm A07), 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.
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.
P.43 - Maximum installation voltage THD alarm threshold, beyond which the alarm A10 THDV too high is generated.
P.44 – Maximum installation current THD alarm threshold beyond which the alarm A05 voltage too low is generated.
P.45 – Maintenance interval in hours. When it is elapsed, the alarm A12 Ordinary maintenance will be generated. The hour count
increments as long as the device is powered. (**) If the controller is installed on the ICAR cabinet
P.46 – Function of the semi-circular bar-graph.
Kvar ins/tot: The bar graph represents the amount of kvar actually inserted, with reference to the total reactive power installed in
the panel.
Curr act/nom: Percentage of actual plant current with reference to the maximum current of the CT.
Delta kvar: bar graph with central zero. It represts the positive/negative delta-kvar needed to reach the setpoint, compared to the
total kvar installed.
P.47 – Default measure shown on the secondary display. Setting the parameter to ROT, the different measures will be shown with a
sequential rotation.
P.48 – If set to ON, the display backlight flashes in presence of one or more active alarms.
P.49 – Serial (node) address of the communication protocol.
P.50 – Communication port transmission speed.
P.51 – Data format. 7 bit settings can only be used for ASCII protocol.
P.52 – Stop bit number.
P.53 – Select communication protocol.
P.54 - Defines the number of the step (considering the step that has the highest count) beyond which the maintenance alarm A12 is
generated. This parameter should be used as an alternative to P.45.If both P.45 and P.54 are set to a value other than OFF, then P.45
has priority.
