P02.01
– The value of the primary current transformer. Example: with CT 800/5A set 800.
If set to OFF, after the power-up the device will prompt you to set the CT and allow direct access to this parameter.
P02.02
– Value of the secondary of the current transformers. Example: With CT 800/5A, set 5.
P02.04
– Defines on which and on how many phases the device reads the current signal. The wiring of current inputs must match the value set for this parameter. Supports all possible combinations of parameter
P02.06.
P02.05
– Reading the connection polarity of the CTs.
Aut
= Polarity is automatically detected at power up. It can be used when working with one CT only and when the system has no generator device.
Dir
= Automatic detection disabled. Direct connection.
Rev
= Automatic detection disabled. Reverse wiring.
P02.06
– Defines on which and on how many phases the device reads the voltage signal.
The wiring of voltage inputs must match the setting for this parameter. Supports all possible combinations of parameter P02.04.
P02.07
– Value in kvar of the smallest step installed (equivalent to the step weight 1). Rated power of the capacitor bank provided at the rated voltage specified in P02.08 and referred to the total of the three
capacitors for three-phase applications.
P02.08
– Rated nameplate voltage of capacitors, at which the specified power of P02.07 is supplied. If the capacitors are used at a voltage different (lower) than rated one, the resulting power is automatically
recalculated by the device.
P02.09
– Working frequency of the system.
Auto
= Automatic selection between 50 and 60 Hz at power up.
50Hz
= Fixed at 50 Hz.
60Hz
= Fixed to 60 Hz.
Variable
= Measured continuously and adjusted.
P02.10
– Minimum time that must elapse between the disconnection of one step and the subsequent reconnection both in MAN and AUT. During this time, the number of the steps on the main page is shown in light
grey.
P02.11
– Connection sensitivity. Parameter that sets the controller reaction speed. With low values, regulation is fast (more accurate around the setpoint but with more step switchings). With high values instead,
there are slower regulation reactions with fewer switchings of the steps. The delay time of the reaction is inversely proportional to the request of steps to reach the setpoint: waiting time = (sensitivity /
number of steps required).
Example: Setting the sensitivity to 60s, if you require the connection of one step of weight 1, expected time is 60s (60/1 = 60). If instead, a total of 4 steps is needed, expected time is 15s (60/4 = 15).
P02.12
– Disconnection sensitivity. Same as the previous parameter but related to disconnection. If set to OFF, the disconnection has the same reaction time as connection set with the previous parameter.
P02.13
– Setpoint (target value) of the power factor (cosphi). Value used for standard applications.
P02.14 – P02.15
– Alternative setpoints selectable with combinations of digital inputs programmed with the appropriate function.
P02.16
– Setpoint used when the system is generating active power to the supplier (greater precision around the setpoint but greater number of operations).
P02.17 – P02.18
– Tolerance around the setpoint. When the cos
is in the range set by these parameters, in AUT steps are not inserted/removed, even if the kvar-delta is greater than the smallest step.
Note: + means “tends to inductive”, - means “tends to capacitive”.
P02.19
– If set to ON, when the system is giving active power to the supplier (generation = negative active power and power factor), all steps are disconnected.
P02.20
– Rated current of the system. Value used for the full scale of the bar graphs and for setting the current thresholds, expressed as a percentage.
If set to Aut, then the value of P02.01 (CT primary) is used.
