P Resence Of Blocking Reactors - Ducati R5 Assembly And Use Instructions

WARNING: by confirming the value, the new setting will be immediately implemented and the previous will be
overwritten. If a bank for which the discharge time has not been elapsed is set to "ON", the insertion will take place after
time elapsing.
Then the pages relating to banks from 2 to 5 will be displayed.
NOTE: to confirm also in manual mode the status of all outputs as before the activation of manual mode, press key
.
Once sequence is completed, the R5 Controller will move to the cosphi measurement page, signalling that the
manual power factor correction mode is active through the dedicated icon coming on:
The manual power factor correction mode can be deactivated:
o
from any displaying page of measurements by pressing key
o
by accessing the Setup Menu and setting to "OFF" the Manual power factor correction mode parameter.
Chap. 8.8
Refer to
NOTE. if the Manual power factor correction mode had been accessed before auto-acquisition, when quitting it the
controller will perform the standard auto-acquisition procedure specified in Complete auto-acquisition
Reduced auto-acquisition

8.9 Presence of blocking reactors
If controller is used on an equipment provided with capacitor banks with blocking reactors (or equivalent devices),
make the following settings:
1.) 
Enter, for the Capacitor nominal voltage parameter
For example, if network nominal voltage is 400V, enter "400".
2.) 
Enter for parameters Step n power (n=1,2,3,4,5)
reactive power at network voltage and not the relevant nominal value.
For example, if the capacitor nominal voltage specified on the plate is 5kVAR at a nominal voltage of 500V and the
network nominal voltage is instead 400V, set the parameter to 4kVAr by entering the value "4.00k".
3.) 
Enable parameter P.8
