r1 On OFF

Normally the display shows the system cos..

Aminus sign indicates a capacitive power factor.

N.B.: In the event of a power cut, the controller will not be able to

calculate the cos phi and will alternately display “ ” & “ ”.

Press the key to display the measurement readings: every

time you press, the next parameter will be displayed.

The parameters are displayed in the following sequence:

(system power factor)

(effective measured line voltage)

(line current measured at the primary winding of the CT)

(equivalent active power absorbed by load, in kW)

(equivalent reactive power absorbed by load, in kVAr)

(crest factor normalized to 1: values less or greater than

1 if harmonic distortion is present)

(temperature inside panel board enclosure at the point

where the controller is installed; the value shown may be

considered reliable after about 1 hour of operation)

Press the key until the

corresponding LED lights up: the controller is now ready to be

programmed in the manual mode.

The user must indicate the desired status for every output relay:

at the end of the programming procedure, the controller will set all

the capacitor steps in the status requested. Operatively, REGO

indicates

“ ” in turn with the status (which can be “ ” or “ ”);

Ex.

for about two seconds

SEMI-GEOMETRIC LOGIC

IMPORTANT

first

s:s:s:

DATA

IMPORTANT: If the controller is installed on a DUCATI

ENERGIA power factor correction system, we advise the user

not to change the default parameters (See Table 2 - Page 74).

It is identified by the code 1:2:2 and the power of the first bank

must be half that of the others, which must all be equal. The first

bank is managed according to a geometric logic whereas all the

others, which have equal powers, are managed according to a

linear logic.

: the first output relay must always be connected to

the capacitor bank with the least power. If the powers of the steps

are all equal, only make sure that the first step is not left without

controlled capacitors. Moreover, in the event that a specific user

program is configured (as in Table 1), the value of the bank

must be set.

10.9 “ ” = Display of set logic At the end of an automatic

acquisition or manual setting procedure, the controller will

display a switching sequence and 72 will start to work

automatically. If the controller cannot identify an optimal

sequence, it will set the 1:1:1 logic.

Ex.

Press to go back to the first parameter in the menu. To

exit the setup menu, keep the key pressed down for

three seconds
