- When powered, the controller remains stuck on “ ”

When no bank is switched on, the controller displays a capacitive

cosø. (negative cosø.)

- The controller displays a cos. that does not correspond to the

system’s.

- The controller alternately displays “ ” and “ ”.

- The controller displays a cos. below the one set and fails to

switch on any banks.

- The controller switches on all the banks even in the absence of

loads and fails to switch them off.

- Check the positioning and connection of the C.T. (See chap. 6 -

Page 60) INSTRUCTIONS FOR C.T. INSTALLATION)

- Check that a current greater than 200mA is circulating on the

secondary winding of the C.T. (the power factor correction

function requires a working load).

- Check that the setup parameters have been correctly

configured (See chap.10 - Page 65 – SETUP PARAMETERS).

In particular:

- the parameter (C.T. ratio – e.g.: with a C.T. 200/5, IL=40)

- the parameter must be “ ”

:if you wish to reinstate all the default parameter

settings recommended by DUCATI ENERGIA, reset the

controller as directed in chap.12.9 - Page 81 – TOTAL

RESETTING OF SETUP PARAMETERS) and start all over

again from the procedure (See chap. 7 -

Page 62 – POWERING UP FOR THE FIRST TIME).

- Check that the generator power factor correction mode ( ) is

(See chap.12.8 - Page 80 – GENERATOR POWER

FACTOR CORRECTION MODE).

- Make sure that the controller has correctly acquired the

powers of the capacitor banks (See chap.12.2 - Page 76 –

DISPLAYING THE POWERS OF SINGLE STEPS).

- Check that the output relays are not disabled (See chap.12.4 -

Page 77 – PROCEDURE FOR ENABLING/DISABLING

OUTPUT RELAYS IN THE AUTOMATIC MODE)

- either increase or decrease the parameter (see chap.

10.2 - Page 66 – Power factor desired in the system) until

reaching a balance condition.

- Increase the parameter (see chap. 14 - Page 87), thus

delaying the connection of banks.
