Page 16: Keep Alive
With “keep alive” enabled (P.250>0), the S2014 will try to keep a minimum excitation current during the start-up. As default P.250 is adjusted to 5. This means that the S2014, during the start-up, will try to keep the excitation current to 5% of the rated excitation current (P.000). -
Page 17: Limiters
BELTRAME CENTRO SERVIZI ENERGIA 5.4 Limiters 5.4.1 V/F Limiter The V / Hz limit is active during the voltage control phase. It works by limiting the Generator voltage as the frequency falls below the maximum frequency P.131. This operation can avoid the Generator over-flushing in case of a reduction of speed. -
Page 18: Maximum Excitation Current: Over Excitation Limiter
BELTRAME CENTRO SERVIZI ENERGIA 5.4.3 Maximum excitation current: Over Excitation limiter The limit of maximum excitation current operates a limitation on the maximum excitation current. The limit works in order to avoid to overtake the P.001 value, and if the excitation current remains on P.001 for longer than P.032, the AVR reduce the excitation current to 102%. -

Page 21: 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 22: 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. -
Page 23: 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. -
