R Educed Auto - Acquisition - Ducati R5 Assembly And Use Instructions

6.2 Reduced auto-acquisition
Here below is the reduced acquisition procedure applying to R5 Controllers:
o
whose factory settings have been modified according to the procedure described in
and on which no previous auto-acquisition has been performed;
o
that are installed on Ducati Energia equipment and are powered on for the first time;
o
have at least one of the Step n power (n=1,2,3,4,5) parameters not equal to zero and on
which a Auto-acquisition reset procedure has just been performed
1.) 
At first system power-up or at power-up after a restart forced by the reset procedure, the R5 Controller performs an
automatic insertion of capacitor banks to check the connections and the amount of bank power.
In order to properly perform these initial checks, you must:
o
turn off any generation plants (if present);
o
make sure the system load is stable and that the current measured by the controller is not a non-zero current and
0.7% higher than the CT secondary winding
2.) 
Before checking the connections, the controller will show the setting screens of the values of
o
CT primary winding (fig. 1a, 1b) (to enter the numerical value, refer to
o
CT secondary winding (fig. 2a, 2b) (to enter the numerical value, refer to
With no input current, the Controller will not show these screens and:
o will move to the cosphi measurement page showing
o the controller will also indicate the signals relating to the low current alarm
Under these circumstances:
o
it is anyway possible to access the Setup Menu
If in this phase even just one of the Step n power (n=1,2,3,4,5) parameters is modified, when the Controller will
measure a stable non-zero current, aReduced auto-acquisition procedure will be performed
o
it is anyway possible to move to the Manual power factor correction mode
banks;
When the controller will measure a stable non-zero current, it will show the setting pages relating to CT primary
winding and CT secondary winding (fig. 1a, 1b, 2a and 2b)
