Is Aux Input Type

correct?

If Aux Input is

used, check Input

Type for correct

setting (e.g. 4-20

mA); Turn off Aux

Input if not needed

Are UP/DOWN

contact inputs

influencing set

point?

Monitor Contact

Offset; Adjust as

necessary

Monitor Droop

Offset; Set Droop

to 0% if not

needed

Is Droop function

influencing set

point?

Are PT (if used)

correct?

Check the regulator for PT

Ratio setting and

adjust as

necessary. Check

PT polarity.

GENERATOR VOLTAGE NOT

MATCHING SET POINT

Does the

regulator
