Page 23: Automatic Voltage Regulator (Avr)
BELTRAME CENTRO SERVIZI ENERGIA 6.1 Automatic voltage regulator (AVR) The AVR automatically controls the output voltage at the generator terminals. This is the main working mode. The AVR function is active if P300=1. As alternative it is possible to activate the AVR function programming the digital input I002=4, and closing the external contact. -
Page 24: Power Factor Regulation (Pf)
BELTRAME CENTRO SERVIZI ENERGIA 6.3 Power Factor regulation (PF) The AVR controls in automatic mode the power factor at generator terminals. The PF function is active when P300= 1, and I002= 5; once the 52G digital input (generator in parallel) is closed, the PF function starts to work. Generator current reading is necessary to use this function. -
Page 25: Digital Reference Adjustment By Calibrator (Up/Down)
BELTRAME CENTRO SERVIZI ENERGIA 6.5 Digital reference adjustment by calibrator (Up/Down) In AVR mode, by programmed digital inputs (I.000=1 increase, I.001=2 decrease) on CN3 connector, it is possible to adjust the nominal voltage set point in a range between -r.010% and +r.010%. The same function is available in FCR mode, in this case the UP/DOWN input is influencing the excitation current. -
