Wrong Connection / AI - Automatic Initialising:
A pfc-relay needs a correct connection of voltage and current (polarity and
phase), for a proper function. If this is not the case, connection must be
corrected. As this is not always possible, BLR-CX is offering alternativly the
following functions:
Manual Correction:
SETUP / 200
Automatic Initialising:
SETUP/ 100 / Ai
Ai is connecting and disconnecting all control exits several times on and
off. Duration for this is several minutes! Not connected exits get steptype
Foff. Stepsizes are not detected by this function!
After finished Ai, BLR-CX has to be checked for correct function!
Requirements for successful operation of Ai:
-
voltage is within tolerance
-
CT is conencted (no simulation!)
-
capacitor banks are installed and fuses are insert
Possible problems for function of Ai:
-
load variations
-
small current signals (big CT-ratio, small stepsizes)
Failure indication Ai / Abrt:
Ai is abort, as no clear result could be achieved,PFC = OFF.
