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 for at least 2sec;
o by accessing the Setup Menu and setting to "OFF" the Manual power factor correction mode parameter.
Refer to Chap. 8.8 for further details.
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 Chap. 6.1 and
Reduced auto-acquisition Chap. 6.2.

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 Chap. 7.2.1, a value corresponding to network nominal voltage.
For example, if network nominal voltage is 400V, enter "400".
2.)
Enter for parameters Step n power (n=1,2,3,4,5) Chap. 7.2.6 the values corresponding to capacitor equivalent
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 – Presence of blocking reactors by setting it to “ON” and, if necessary, edit the parameters
P.11 – Degradation threshold 2 and P.12 – Fault threshold 2. For further details, refer to Chap. 7.6.
