Avr mx321 wiring diagram. Stamford mx321 automatic voltage regulator. Stamford as540 automatic voltage regulator. Refer to alternator wiring diagram for connection details. Mx321 automatic voltage regulator avr for cummins 1250kva generators. Signal injected into the avr and increases the droop with lagging. Stamford as480 automatic voltage regulator.
Mx automatic voltage regulator avr specification controls and accessories voltage. The main stator provides power for excitation of the exciter field via the sx460 sx440 or sx421 avr which is the controlling device governing the level of excitation provided to the exciter field. Vac to vac maximum 3 phase 3 wire refer to alternator wiring diagram for connection details. The avr responds to a voltage sensing signal derived from the main stator winding. Excitation power is derived. The droop adjustment is normally preset in the works to give 5 voltage droop at full load zero power factor.
Mx321 automatic voltage regulator avr specification controls and accessories. Is connected to s1 s2 on the avr see generator wiring diagram for details. Clockwise increases the amount of ct. Mx321 avr controls 6 a043y701 issue 2 32 initial avr setup notice the avr must be setup only by authorised trained service engineers. S1 s2 on the avr see generator wiring diagram for details. Stamford mx341 automatic voltage regulator.
Refer to wiring diagram before removing the shorting link and connecting the droop transformer. 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. Signal injected into the avr and increases the droop with lagging power factor cos 0. Is connected to s1 s2 on the avr see generator wiring diagram for details. The droop transformer must be connected in the correct main output terminal for proper operation details are as shown in the machine wiring diagram. 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.
Clockwise increases the amount of ct. Control function turn potentiometer clockwise to. Power factor dependent signal for the avr. Mx321 is a three phase sensed automatic voltage regulator and forms part of the excitation system for a brush less generator. The droop adjustment is normally preset in the works to give 5 voltage droop at full load zero power factors.
