APPENDIX C
QUICK START PROGRAMMING GUIDE
As the DVR
®
2000E+ 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 procedure 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 termi-
nals 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 regulator terminals 3 and 4. This will provide the regulator with
enough power to accept programming, but not enough power for normal operation.
3. Press the SELECT button. The word StZE will appear in the display. Press the ENTER button. 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 StZE.
4. Press the SELECT button. The word REG will appear in the display. Press the ENTER button. 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 the SELECT button. The word STPT will appear in the display. Press the ENTER button. 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 the SELECT button. The word UFRq will appear in the display. Press the ENTER button. 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 the SELECT button. The word DROP will appear in the display. Press the ENTER button. Use the
UP and DOWN arrows to select the appropriate level of droop as a percentage of desired sensed volt-
age 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 the SELECT button. The word AU will appear in the display. Press the ENTER button. 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 form the regulator.
10. Completely reconnect the regulator to the generator.
The regulator is now ready to be placed in service
