Step 5. Low generator output voltage may occur when operating in droop mode with an inductive load. Refer
to Section 3 – Features and Protection for more information about the Load Sharing function.
If the low voltage condition is not caused by the droop function, proceed to Step 6.
Step 6. Low generator output voltage may occur when the regulator input is being influenced by the auxiliary
input. Refer to Section 3 – Features and Protection for more information about the Auxiliary Input func-
tion.
If the low voltage condition is not caused by the auxiliary input, proceed to Step 7.
Step 7. Low generator output voltage may occur when the regulator input is being influenced by the UP and
DOWN contacts. Refer to Section 3 – Features and Protection for more information about the UP and
DOWN contacts.
If the low voltage condition is not caused by the UP and DOWN contacts, proceed to Step 8.
Step 8. Further system troubleshooting may be required. If it is determined that the rest of the system is not the
source of the problem, the DVR
®
2000E+ may need to be replaced.

Step 2. Check for generator overloading.
If the generator is operating with a larger than rated load, shed load.
If the generator is operating at rated or less than rated load, proceed to Step 3.
