Parameter table (continued)
P01 – VThe value of the primary current transformer. Example: with CT 800/5 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.
P.02 - Value of the secondary of the current transformers. Example: with CT 800/5 set 5.
P.03 - Denes on which phase 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 P.05.
P.04 - Reading the connection polarity of the CT.
AUT = Polarity is automatically detected at power up. Can only be used when working with only one CT and when the system has no generator device.
Dir = Automatic detection disabled. Direct connection.
Rev = Automatic detection disabled. Reverse wiring (crossover).
P.05 - Denes 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 P.03.
P. 0 6 - 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 specied in
P. 0 7 .
P.07 - Rated plate capacitor, which is delivered in specied power P.06. If the capacitors are used to a voltage dierent (lower) than nominal, the resulting
power is automatically recalculated by the device.
P.08 - Working frequency of the system:
Aut = automatic selection between 50 and 60 Hz at power on.
50Hz = xed to 50 Hz.
60Hz = xed to 60 Hz.
Var = variable, measured continuously and adjusted.
P.09 - Minimum time that must elapse between the disconnection of one step and the subsequent reconnection both in MAN or AUT mode. During this time
the number of the step on the main page is blinking.
P.10 - Connection sensitivity. This parameter sets the speed of reaction of the controller. With small values of P.10 the regulation is fast (more accurate around
the setpoint but with more step swithchings). With high values instead we’ll have slower reactions of the regulation, 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 request the insertion of one step of weight 1 it is exptected 60s (60/1 = 60). If instead serve a total of 4 steps will
be exptected 15s (60/4 = 15).
P11 ... P18 - Function of output relays 1 ... 8:
OFF = Not used.
1..32=Weight of the step. This relay driv
es a bank of cpacitors which power is n times (n = 1…32) the smallest power dened with parameter P.06.
ON = Always on.
NOA = Alarm normally de-energized. The relay is energized when any alarm with the 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.
A01 ... A13 = The relay is energized when the alarm specied is active.
P.19 - Setpoint (target value) of the cosphi. Used for standard applications.
P.20
- Language of scrolling alarm messages.
