When the CT secondary current signal is lower than 2 amps, the C/K value should be increased by 0,1
• When using the regulator on 220/230 Vac networks the C/K values should be doubled.
•
“-” means installation of C.T. with primary value too small.
•
••
• PF setting
After setting the C/K value, press the
Select
button again for 4 secs to indicate the selected PF required. At
the same the red led
PF
will illuminate. To release the
Select
button and use the
+
or
_
buttons to
change the selection. A PF of 0.95 is recommended.
Example: setted C/K = "0.3" setted PF = "0.97"
The regulator will switch bank to achieve a PF value within 0.94 and 1.00 (0.97 ± 0.03)
The “-” led near the two numbers display is illuminate if the P.F. value is more than 1.00.
6.1 SAVING the SET VALUES
By pressing the
Prog.
button the C/K and P.F. values which have been selected will be saved and the Regulator
works in AUTOMATIC condition.
