BE1-25A Functional Description 3-9
VOLTAGE MATCHING MODULE V1
Module V1 issues corrective signals to the generator control system that cause the voltage to approach the
voltage of the bus. The corrective output signal is in the form of a continuous contact closure.
This module is, in turn, controlled by whichever voltage acceptance module is in the system. (One of these,
either A1 or A2, must be present in order for module V1 to function.)
An inhibit signal from the A module, AINH, will disable the V1 output (Figure 3-8). Additional A-module
signals, raise and lower, determine whether the output will raise or lower the generator voltage.
If the generator voltage is less than the generator undervoltage setting, voltage correction pulses are
inhibited.
