‘SELECT’
button to select
LED 4, ‘Manual Mode Adj.’
Press the
‘UP’
button to increase the fi eld current until
LED 2
li
ghts. This should increase the generator
voltage a small amount. If everything is still okay, continue increasing the fi eld current until the desired
generator voltage is reached. Check that all of the voltages are still balanced line to line and line to
neutral.
9.) P
ress the
‘SELECT’
button to select
LED 3, ‘Manual Mode On/Off’.
Press
the
‘DOWN’
button to turn off the manual mode and put the regulator in
‘AVR’
mode. Check that
voltages are still cor
rect. If necessary, press the
‘SELECT’
button to select
LED
11, ‘Fine Voltage’
adjust. Use the
‘
UP’
and
‘DOW
N’
buttons to obtain the correct reading on the voltmeter.
Note: If the generator is to ope
rate at several diffe
rent voltages
,
set the gain for the lowe
st voltage.
10.) Press the
‘S
ELECT’
button to select
LED 10, ‘Gain’
adjust.
Use the
‘UP’
button to increase the gain until the voltage starts to become unstable. Reduce the gain
until the voltage becomes stable by pushing the
‘DO
WN’
button. Pus
h the
‘DOW
N’
button 5 more times.
Press the
‘SELECT’
button again so that this setting is saved in permanent memory.
Note: When the regulator is in normal
‘AVR’
operating mode (no
LEDs are on). Press
ing the
‘
UP’
or
‘DOWN’
button will cause the regulator to default to the
LED 11, ‘Fine Voltage’
