3.) Press t
he
‘SELECT’
button one time.
LED 3, ‘M
anual Mode On/Off’
should now be blinking.
Use the
‘UP’
button to move t
he steady LED to
‘2’
for
‘Man
ual
Mode’
On.
Note: For the fi rst time start up of the generator, the
‘Manual Mode’
should be turned on. This is
important for higher voltage generators to insure connections are correct before damage is done. For
normal operation, the
‘Manual Mode’
must be turned off (
LED 1
on steady).
4.) Press the
‘SELECT’
button twice.
LED 7, ‘Underfrequency’
should now be blinking.
Note: Regulators without the ‘C’ option will skip
LED 5
and
LED 6
. If
LED 5
is blinking, then the
regulator is a DVR
®
2000EC. If this regulator was obtained to allow paralleling with the Utility, then
STOP
.
This document will not provide the necessary instructions for paralleling with the Utility. If it is intended
that this regulator will be used on a stand-alone generator, then with
LED 5
blinking, use the
‘DOWN’
button to insure that
LED 1
is on. Press the
‘SELECT’
button until
LED 7
is blinking.
Use the
‘UP’
and
‘DOWN’
buttons to select the desired underfrequency setting. Table 2-11 in the
DVR
®
2000E manual will provide the complete range of settings. The selected setting is the frequency
at which the regulator will begin to reduce the operating voltage, as speed is reduced, to protect the
generator.
The de
fault fa
ctory
setting is 59 Hz. This is
LED 10
and is correct for 60 Hz operation.
LED 10
indicates
a r
ange of 58.8 to 60.8 Hz. When the setting is increased from
LED 9
to
LED 10
, the setting will be 58.8.
Two additional pushes of the
‘UP’
button will increase the setting to
‘59’
.
For 50 Hz operation, decrease the setting to 49 Hz. Push the
‘DOWN’
button
until
LED 5
is lit. This is
‘50.4 Hz
.’
Push the down button 14 times.
LED 5
will remain lit, but the se
tting will be reduced to
‘49
Hz.’
5.) Press the
‘SELECT’
button twice.
LED 9, ‘Stability Range’
should no
w be blinking.
Use the
‘UP’
and
‘D
OWN’
buttons to adjust the setting according to the desire

6.) Press the
‘SELECT’
button one time.
LED 10, ‘Gain’
should no
w be blinking. This will save the

‘Stability Range’
setting.
7.) The power source can now be removed from t
he regulator. The regulator can be connected
to the
generator. The generator set can be started and brought up to rated speed. With
the regulator in manual
and 0 output, the generator ou
tput should be residual voltage. All line to line and line to n
eutral voltages
should now be checked
f
or balance and equal voltages
to insure that everything is connected properly.
