1 Publication: 9 2875 00 991 Revision: B 08/01 INSTRUCTION MANUALforDECS-100 digital excitation control SystemDECS-100 IntroductioniINTRODUCTIONThis INSTRUCTION MANUAL provides information about the operation and installation of the decs -100 digital excitation control system . To accomplish this, the following information is Information and Specifications&Human-Machine Interface&Functional Description&Installation&BESTCOMS Communication Software&Installation and TroubleshootingWARNING!To avoid personal injury or equipment damage, only qualified personnel shouldperform the procedures in this voltage is present at the rear panel when the unit is energized.

2 Rearpanel connections should be made only when the unit is MANUAL mode excitation level must be evaluated prior to enabling thisfeature. If the level of excitation current is inappropriate for the generator,severe damage to the generator may PID numbers will result in poor system performance or uploading a settings file, remove operating power from the decs -100,disconnect the field wiring from terminals F+ and F , and re-apply operatingpower to the uploading a settings file, remove operating power from the decs -100,disconnect the field wiring from terminals F+ and F , and re-apply operatingpower to the decs -100.

3 NOTEBe sure that the decs -100 is hard-wired to earth ground with no smaller than12 AWG copper wire attached to the ground terminal on the rear of the unit the unit is configured in a system with other devices, it is recommendedto use a separate lead to the ground bus from each IntroductioniiFirst Printing: March 2001 Printed in USA 2001, Basler Electric, Highland, IL 62249 USAA ugust 2001It is not the intention of this MANUAL to cover all details and variations in equipment, nor does thismanual provide data for every possible contingency regarding installation or operation.

Typical V/Hz 1-3 decs -100 General Information1-1 SECTION 1 GENERAL INFORMATIONGENERALThe Basler digital excitation control system ( decs -100) is an electronic, solid-state, microprocessor basedcontrol device.

8 The decs -100 regulates the output voltage of a brushless, ac generator by controlling thecurrent into the generator exciter field. Input power to the decs -100 can be from a multi-pole,high-frequency, permanent magnet generator (PMG) or from the generator output when used as aconventional, shunt-excited, excitation decs -100 is supplied in an encapsulated package designed for behind-the-panel mounting. TheDECS-100 is held in place by thread-forming screws that thread into its plastic shell.

9 Front panel indicators(LEDs) annunciate decs -100 status and system conditions. decs -100 connections are made throughquarter-inch, quick-connect terminals on the rear panel. A 9-pin DB-9 type connector on the rear panelprovides communication between the decs -100 and an IBM compatible units have the following features and control modes: automatic voltage regulation (AVR), MANUAL or field current regulation (FCR),power factor (PF) regulation, and reactive power (var) stability start and voltage buildup control with an adjustable ramp in AVR control (OEL) limiting in AVR, var, and PF control (volts/hertz) or single-phase generator voltage (RMS ) sensing/regulation in AVR bus voltage (RMS )
