→ Connect to the exciter stator (not the main rotor). Polarity matters for correct residual voltage buildup.

Used to set the knee point for under-frequency protection, typically protecting the exciter if the engine speed drops below rated levels. an-5-203 avr wiring diagram pdf

, the following terminal connections are standard for this model: Main Winding Input: 400VAC, 50Hz/60Hz. Auxiliary Winding Input: AC 55V–220V. Excitation Output (F+, F-):

Wire F+ and F- to the exciter field. Polarity matters. Reverse polarity will cause the generator to build negative voltage or fail to build at all. The PDF indicates which color from the AVR goes to which exciter lead. → Connect to the exciter stator (not the main rotor)

These cables monitor the generator's phase output. Ensure these are securely connected to the main stator output terminals. Loose or corroded "A-B-C-D" cables often cause uneven phase voltages (e.g., 12V on one phase and 6V on others).

AN-5-203 AVR is a standard automatic voltage regulator used primarily in Denyo DCA series "AVR AN-5-203 Automatic Voltage Regulator for Generator
