8.4. CONTROL PUSHBUTTONS
The following control pushbuttons are located on the front faceplate keypad.
8.4.1. RUN/OFF/AUTO/LOAD TEST

automatic engine start and load transfer. Once initiated, the engine will receive a
start signal from the transfer switch and upon the generator reaching nominal
voltage and frequency levels, a load transfer will be initiated. The generator set
