Analog Inputs

The CGCM unit provides a number of analog inputs for use in the regulation
and control of stand-alone and paralleled generator systems. Each of the inputs is
outlined below.

Generator Voltage Sensing Inputs

The CGCM unit senses generator voltage through voltage transformers (VTs)
installed across the generator output leads.
