COMMISSIONING
2.1 - Electrical checks on the AVR
- Check that all connections have been made properly as
shown in the attached wiring diagram.
- Check that the ST3 frequency selection jumper is on the
correct frequency setting.
- Check whether the ST4 jumper or the remote adjustment
potentiometer have been connected.
2.2 - Settings
The machine is tested and set at the factory. When first
used with no load, make sure that the drive speed is
correct and stable (see the nameplate). After operational
testing, replace all access panels or covers.
The only possible adjustments to the machine should be
made on the AVR.
2.2.1 - R 230 settings (shunt system)
Initial potentiometer settings
-
P1
potentiometer (AVR voltage adjustment): fully anti-clockwise.
- Remote voltage adjustment potentiometer: centre position.
Run the alternator at its rated speed. If the voltage does not
increase, the magnetic circuit should be remagnetized (see
section 2.3).
- Turn the AVR voltage adjustment potentiometer
P1
slowly
until the output voltage rated value is obtained.
- Adjust the stability setting using
P2.
- Sealed potentiometer
P3
is factory set at 48 Hz for 50 Hz
and 58 Hz for 60 Hz
2.2.2 - Special type of use
2.2.2.1 - R230 field weakening (SHUNT)
The exciter is switched off by disconnecting the AVR power
supply (1 wire - 0 or 110V).
Contact rating : 16A - 250V alt.
