Over 15 years of industrial field engineering experience in diesel generator electrical controls, AVR excitation systems, governor calibration, and OEM parts replacement.
View Full Profile & Published Guides →When a diesel generator refuses to shut down after turning off the key switch or sending a stop command from the controller, the fault typically traces to a malfunctioning fuel shut off solenoid or its control circuit. This guide details the operating differences between Energize-to-Run (pull-to-run) and Energize-to-Stop (pull-to-stop) topologies, step-by-step electrical and mechanical isolation procedures, emergency shutdown precautions, and how to correctly match replacement solenoids.
Read More »Upgrading and replacing diesel generator control units requires precise matching of control topology (Auto Start vs. Auto Mains Failure), panel cutout dimensions, AC sensing range, and terminal pin assignments. This technical guide details retrofit procedures for Deep Sea DSE4520 AMF controllers, comparing verified specifications with the DSE4510 and compact DSE3110, mapping terminal conversions from obsolete models (DSE4110, DSE4120, DSE704, DSE720, DSE5110), explaining AMF dual-source interlocking, and outlining commissioning protocols.
Read More »Selecting and replacing Automatic Voltage Regulators for Leroy Somer alternators requires matching excitation topology (Shunt, AREP auxiliary windings, or PMG), sensing voltage range, and overload capability. This guide details drop-in replacement procedures for upgrading obsolete R438 and R448 boards to the universal R450, configuring the compact R120 for shunt alternators, terminal wiring conversions, potentiometer calibration (P1-P4), and static diode testing.
