Avr mx321 wiring diagram. Excitation power is derived from a three phase permanent magnet generator pmg to isolate the avr control circuits from the effects of non linear loads and to reduce radio frequency interference on the generator terminals. Excitation power is derived. Mx321 automatic voltage regulator avr specification controls and accessories. Mx321 avr controls 6 a043y701 issue 2 32 initial avr setup notice the avr must be setup only by authorised trained service engineers. Red capacitor generator circuit diagram avr mx mx is a three phase sensed automatic voltage regulator and forms part of the excitation system for a brush less generator. The droop transformer must be connected in the correct main output terminal for proper operation details are as shown in the machine wiring diagram.
Refer to wiring diagram before removing the shorting link and connecting the droop transformer. Clockwise increases the amount of ct. Signal injected into the avr and increases the droop with lagging power factor cos 0. Refer to alternator wiring diagram for connection details. Signal injected into the avr and increases the droop with lagging. Power factor dependent signal for the avr.
The droop adjustment is normally preset in the works to give 5 voltage droop at full load zero power factors. S1 s2 on the avr see generator wiring diagram for details.
