QUICK START PROGRAMMING GUIDE
As the DVR
®
is designed to work on many Marathon
Electric generators in many different applications, it
is necessary to program the regulator prior to putting
it in service. Please observe the following proce-
dure to program the regulator through the Human-
Machine Interface or HMI:
1. Disconnect all connections to the regulator.
2. Apply power to terminals 3 and 4 of the
regulator. There are two acceptable ways to
power the regulator for programming:
a. Reconnect the ground lead and the leads
from the capacitor in the PMG circuit to
regulator terminals 3 and 4. This is how
the regulator receives power for normal
operation. If using this method, be sure
the generator RPM is between 1500 and
1800 RPM to provide proper input power
to the regulator.
b. Connect a 120 Volt AC source to regu-
lator terminals 3 and 4. This will pro-
vide the regulator with enough power
to accept programming, but not enough
power for normal operation.
3. Press SELECT . The word SIZE will appear
in the display. Press ENTER . Use the
UPand DOWNarrows to select the
appropriate generator frame size and then
press ENTER . The entered value will flash
3 times to indicate that your selection has
been saved. The display will again read
SIZE.
4. Press SELECT . The word REG will appear
in the display. Press ENTER .
 UsetheUPandDOWNarrowstoselect
the appropriate regulation mode (AVR3 for 3
phase Automatic Voltage Regulation; AVR1
for single phase Automatic Voltage Regulation
or FCR for Field Current Regulation) and then
press ENTER . The entered value will flash
3 times to indicate that your selection has
been saved. The display will again read REG.
5. Press SELECT . The word STPT will appear
in the display. Press ENTER . Use the
UPand DOWNarrows to select the
appropriate set point (Sensed Voltage for
AVR3 and AVR1 regulation modes; Field
Current level for FCR regulation mode) and
then press ENTER . The entered value will
flash 3 times to indicate that your selection
has been saved. The display will again read
STPT.
6. Press SELECT . The word UFRQ will appear
in the display. Press ENTER . Use the
UPand DOWNarrows to select the
appropriate Under-frequency threshold and
then press ENTER . The entered value will
flash 3 times to indicate that your selection
has been saved. The display will again read
UFRQ.
7. Press SELECT . The word DROP will appear
in the display. Press ENTER . Use the
UPand DOWNarrows to select the
appropriate level of droop as a percentage
of desired sensed voltage and then press
ENTER . The entered value will flash 3
times to indicate that your selection has been
saved. The display will again read DROP.
8. Press SELECT . The word AU will appear
in the display. Press ENTER .
 UsetheUPandDOWNarrowstoselect
the appropriate auxiliary input mode and
then press ENTER . The entered value will
flash 3 times to indicate that your selection
has been saved. The display will again read
AU.
9. Remove power from the regulator.
10. Completely reconnect the regulator to the
generator.
The regulator is now ready to be placed in service.
