RAPID CT SETUP
When the CT value is not known and only used at the moment of the installation, the P.01 parameter for CT primary can
remain set at OFF while all the others can be programmed. In this case, during the system installation and once the controller
is powered up, the display will show a flashing
CT
(Current Transformer). By pressing
▲▼
the CT primary can be set directly.
Once programmed, press
to confirm. The unit will store the setting into P.01, and directly restart in automatic mode.

PARAMETER TABLE
All the programming parameters are listed in the table below. For each parameter, possible setting range and factory default
are indicated, as well as a brief explanation of the parameter function. The parameter description shown on the display can
in some cases be different from what is reported in the table because of the reduced number of available characters.
However, the parameter code can be used as a reference.
Note
The parameters shown in the table with a shaded background are
essential
to the operation of the system, thus they
represent the minimum required programming for operation.

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)
2
/(460)
2
→
set 7,5kvar).
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.
