ADAPTER 1339906 - Caterpillar

Series Boost Option
The series boost option attachment consists of a series boost module assembly, and a series boost transformer assembly.Series boost allows Self Excited SR4 Generators to stay on the line for approximately ten seconds when there is a short in the generating or load circuits. This ten second feature allows the load circuit breakers a chance to trip in sequence, thus minimizing the possibility of power loss to the entire electrical system. Series boost connections are not the same for all generator sets. Refer to the SR4 Generator Service Manual for all wiring and installation information.For a listing of Caterpillar reference literature, refer to the topic "Reference Literature" in this publication. This literature may be purchased through your Caterpillar dealer.Electromagnetic Interference / Radio Frequency Interference (EMI/RFI) Module Option
This optional filter, connected in series with the voltage sensing leads, is used to meet compliance with MIL STD 461B and VDE 875 level N requirements.Manual Voltage Control Option
A manual voltage control module for either the self excited, or permanent magnet excited SR4 generators is available as an option. Various specifications and certification require manual voltage control of the generator if the automatic voltage regulator should fail.
