P.19 Cos-phi setpoint
P.20 Alarm messages language
P.01 - The 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 – It defines 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.
Inv = Automatic detection disabled. Reverse wiring.
P.05 - 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 P.03.
P.06 - 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 P.07 (exemple: step 10kvar-460V supplied 400V → 10 x (400)
P.07 - Installation rated voltage, which is delivered in specified power P.06.
P.08 - Working frequency of the system:
Aut = automatic selection between 50 and 60 Hz at power on.
50Hz = fixed to 50 Hz.
60Hz = fixed 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 are expected 60s (60/1 = 60). If instead serve a
total of 4 steps will be expected 15s (60/4 = 15).
P11 ... P17 - Function of output relays 1 ... 7:
OFF = Not used .
1 .. 32 = Weight of the step. This relay drives a bank of cpacitors which power is n times (n = 1...32) the smallest power defined 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.
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.
P.19 - Setpoint (target value) of the cosϕ. Used for standard applications.
P.20 - Language of scrolling alarm messages.
