P.01 – Value of the transformer primary current. Example: with CT 800/5, set 800. If set to OFF, after switch-on the device invites you to dene the CT and allows

direct access to the parameter.

P.02 – Value of the current transformer secondary. Example: with CT 800/5, set 5.

P.03 – Denes the phase on which the device reads the current signal. The current input wiring must correspond to the value dened for this parameter.

Accounts for all the possible combinations of parameter P.05.

P.04 – Read the CT connection polarity.

AUT = The polarity is automatically detected on switch-on. Can only be used when working with one CT and when the installation has no electricity-

generating device.

Dir = Automatic detection disabled. Direct connection.

Rev = Automatic detection disabled. Crossover.

P.05 – Denes how many and on which phases the voltage signal is read. The voltage input wiring must correspond to the value of this parameter. Accounts

for all the possible combinations of parameter P.03.

P.06 – Reference power in kVAr relating to parameters P.11 to P.18 (usually the power in kVAr of the smallest installed step), at the nominal voltage stated in

parameter P.07.

P.07 – Nominal voltage of steps.

P.08 – System working frequency:

Aut = automatic selection between 50 and 60 Hz on switch-on.

50Hz = set to 50 Hz

60Hz = set to 60 Hz

Var = variable, measured continuously and adjusted.

P.09 – Minimum time which should elapse between disconnection of a step and its reconnection, in MAN or AUT mode. During this time, the step number on

the main page ashes.

P.10 – Sensitivity on connection. This parameter denes the controller reaction speed. With a low value of P.10 regulation is fast (more accurate around the

setpoint, but with more step switching operations). With high values we have slower regulation reactions, with fewer step switching operations. The

controller time delay is inversely proportional to the demand required by steps to reach the setpoint value: wait = (sensitivity/number of steps required.

For example: with the sensitivity set to 60, if you wish to insert a step, the time is 60 s (60/1 = 60). If 4 steps are needed the time will be 15 s (60/4 = 15).

P.11 ... P.18 – Function of output relays 1 ... 8:

OFF = Not used.

1 .. 32 = Multiplication factor. These relays control steps with a power rating n times (n = 1 ... 32) the reference power dened in parameter P.06.

ON = Always connected.

NOA = alarm normally switched o. The relay is energised when an alarm with the global alarm property appears.

NCA = alarm normally switched on. The relay is de-energised when an alarm with the global alarm property appears.

MAN = the relay is energised when the device is in manual mode.

AUT = the relay is energised when the device is in automatic mode.

FAN = The relay controls the cooling fan.

A01 ... A13 = The relay is energised when the specied alarm is active.

P.19 – Cos phi setpoint (target value). Used for standard application.

P.20 – Alarm message language.
