The
Synchronising circuit is used to keep the Ramp Generator and Low Hz Detector
locked to the generator waveform period. The
Low Pass Filter prevents distorted waveforms affecting the operation of the AVR
control circuit.
The
Short Circuit Detector senses the presence of a short circuit on the generator
output and forces the Power Control Devices into full conduction. This only
occurs when the AVR is powered from an auxiliary winding.
Power
Control Devices vary the amount of exciter field current in response to the
error signal produced by the Amplifier. Suppression
components are included to prevent sub cycle voltage spikes damaging the AVR
components and also to reduce the amount of conducted noise on the generator
terminals.
The
Over Excitation Detector continuously monitors the exciter field voltage and
provides signals, to collapse the output voltage if an over excitation
condition persists for the specified time period. The
Power Supply provides the required voltages for the AVR circuitry.
The generator output
voltage is set at the factory, but can be altered by careful adjustment of the
VOLTS control on the AVR board, or by the external hand trimmer if fitted. If
major adjustment is necessary or you lose stability, follow the ‘VOLTAGE SETUP
PROCEDURE’. Terminals 1 and 2 on the AVR will be fitted with a shorting link if
no hand trimmer is required. Terminals La and Lb are linked only for special
low voltage applications.
