VOLTAGE MATCHING MODULE V2
Like the V1 module, module V2 issues corrective signals to the generator control system that cause the
generator voltage to approach the voltage of the bus. In the case of this module, however, the corrective
signal is not continuous, but rather a train of pulses. The pulse width and pulse frequency are adjusted by
front panel controls.
Module V2 (Figure 3-8) is controlled by whichever voltage acceptance module (A1 or A2) is in the system.
(Either A1 or A2 must be present in order for this module to function.)
An Inhibit signal from the A module, AINH, will disable the V2 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. See Figure 3-8.
