2. DEVICE DESCRIPTION 2.1 Introduction S2014 is an automatic voltage regulator of the latest design for controls alternators excitation. The unit contains the most advanced microprocessor technology together with SCR semiconductor technology (Silicon Controlled Rectifier). A practical and simple-to-operate panel on the unit is used for all control operations. -
Page 7: Area Of Application
2.2 Area of application This advanced-design automatic voltage regulator is used for the excitation of synchronous machines. This unit is only suitable for this one area of application. The regulator can also be switched over to function as a automatic voltage regulator, power factor or reactive power regulation. -
Page 8: Hardware
2.3 Hardware Structure: The device is built into a plastic casing, depending on the nominal output current some models have an aluminum base for cooling. The connection terminals are integrated on top of the circuit boards. Power electronics: The power part is fitted with SCR semiconductors.

Page 16: Limiters
3.4 Limiters 3.4.1 V/f Limiter The V / Hz limit is active during the voltage control phase. It works by limiting the alternator voltage as the frequency falls below the maximum frequency set in parameter P.131. This operation can avoid an alternator over-flushing in case of a reduction of laps. Parameter Description (short) Description... -

Page 20: Field Current Regulation (Fcr)
4.1 Field Current Regulation (FCR) This functioning mode allows to control the regulator output current. In this case the regulator controls only the output current to the regulator excitation terminals without considering what happening externally. This functioning mode could become useful during the regulator commissioning phase or in case of the eventual failure search. -
