NOTE:

DUCATI ENERGIA

7.3 DUCATI ENERGIA

if the incoming current is insufficient (less than 200mA),

REGO cannot determine its direction and will stand by in this

status until current is supplied.

If the controller is installed on a automatic

power factor correction system (pre-programmed controller), no

type of setting will be required and the controller will be ready for

perfect operation: it will alternately display “COS” and the power

factor of the system.

Ex.

If the controller is not installed on a

automatic power factor correction unit (virgin controller),

after displaying the “FAS” parameter it will automatically

launch the automatic procedure for acquiring the powers of

the single capacitor steps. The capacitor steps will be

switched on and measured in sequence a total of three times

each. At the end of this procedure the controller will

alternately display “C1” and the measured power value of the

first step; the power of the next step can be displayed by

pressing the DATAkey.

Ex.

If the power measurements are incorrect, from the same menu

the user can press:

– ALARM/RESET + to launch a new auto acquisition

procedure

– ALARM/RESET + to enter the manual programming

mode (see chap.10.8 - Page 68)

FOR A CORRECT WORKING OF THE

CONTROLLER, C H E C K T H A T P O W E R S

MEASURED BY THE CONTROLLER ARE CORRECT.

If the power measurements are correct, the user can press the

DATAkey for three seconds to exit this menu and the controller will

start to work automatically, displaying the letters in turn

with the system power factor.

Ex.

As soon as the controller is switched on, 8.8.8. will appear on the

display for a few seconds and all the LEDs will light up to enable

their efficiency to be checked.

Subsequently the controller will alternately display and “0”

or “1”;

Ex.

at this stage the system will read and display the direction of the

incoming current from the C.T. (0 = direct / 1= inverted). It is only

an indication.

if the incoming current is insufficient (less than 200mA),

REGO cannot determine its direction and will stand by in this

status until current is supplied.

NOTE:

“COS”

8) SUBSEQUENT STARTUPS

“FAS”

NOTE:

At this point, the controller no longer requires any type of setting

and will be ready for perfect operation: it will alternately display

“COS” and the system power factor.

Ex.

To immediately check whether the controller is working

efficiently, the user should keep in mind that:

– When the load is started, the controller should turn on the

LED and switch the capacitor steps into service.

– If the load is reduced or removed, the controller should turn

on the LED and disconnect capacitor steps accordingly.

– When the and LEDs are off, the controller should display a

cos. close to the one set (see chap.10.2 - Page 66).

– As the inductive cos. increases up to 1, the current circulating

upstream from the power factor correction decreases,

whereas it increases with the capacitive cos.

N.B.:If the controller is installed on a DUCATI energia

automatic power factor correction system we advise the

user not to change any setup parameters with the exception

of and .

To enter the setup menu press The display will show the

following parameters:

10.1 = Mains frequency.

The parameter is displayed in turn with the measured

value. It is only an indication.

Press to go on to the next parameter

10.2 = Power factor desired in the system.

The parameter is displayed in turn with the default

value “0.95”.

The value can be changed using the key.

Press DATAto go on to the next parameter

10.3 “UFF” = Mains voltage

The “UFF” parameter is displayed in turn with the default

value “400”.

The value can be changed using the or key (possible

values 400 or 230).

If the controller is powered by an auxiliary transformer, the

parameter should be set at the rated primary voltage

of the auxiliary transformer (range 100..700). To change

this parameter, press:

N.B.:

UFF

ALARM/RESET + to increase the value.

ALARM/RESET + to decrease the value.
