Indicator

Description

Overexcitation LED #12

This LED blinks rapidly when the Overexcitation Protection feature is enabled

and the ﬁ eld voltage exceeds the setpoint (80 V default) for 15 seconds. The

DVR

2000E will shutdown when an overexcitation condition is detected. The

Overexcitation LED blinks for 5 seconds when the DVR

2000E is powered up

following an overexcitation condition.

Overtemperature LED #11

This LED blinks rapidly when the internal temperature of the DVR

2000E has

exceeded its limit and causes the unit to shutdown. The overtemperature LED blinks

for 5 seconds when the DVR

2000E is powered up following an overtemperature

condition.

Underfrequency LED #7

This LED blinks rapidly during an underfrequency condition.

VAR/PF Active LED #5

This LED blinks rapidly when operating in VAR or Power Factor mode.

If – Limit LED #4

This LED blinks rapidly when the ﬁ eld current exceeds the programmed

overexcitation limit. It will continue to ﬂ ash until the overexcitation condition

ceases or the overexcitation time delay expires and the DVR

2000E shuts down.

The Overexcitation Limiting LED blinks for 5 seconds when the DVR

2000E is

powered up following an overexcitation limiting condition.

Manual Mode LED #3

This LED blinks rapidly when operating in Manual mode.

Loss of Sensing LED #2

This LED blinks rapidly when a loss of generator sensing voltage is detected.

The DVR

2000E will shutdown. The Loss of (Generator) Sensing LED blinks for

5 seconds when the DVR

2000E is powered up following shutdown for loss of

generator sensing condition.

Overvoltage LED #1

This LED blinks rapidly when the generator output voltage exceeds the setpoint

for 0.75 seconds. The DVR

2000E will shutdown when a generator overvoltage

condition is detected. The (Generator) Overvoltage LED blinks for 5 seconds when

the DVR

2000E is powered up following a generator overvoltage condition.

Overexcitation LED #12

and If–Limit LED #4

Both LED’s blink rapidly when F+ and F- are shorted. The DVR

2000E will

shutdown and the LED’s will continue to blink. The LED’s will blink for 5 seconds

when the DVR

2000E is powered up following a ﬁ eld shorting condition.

INITIAL ADJUSTMENTS

Read and understand the operation of the individual adjustments before attempting any initial adjustments.

Before starting the generator, the procedures in the following paragraphs should be performed.

Remove the 5 ampere fuse before starting the generator for the ﬁ rst time. Perform all preliminary engine governor

adjustments without the regulator energized.

After initial governor adjustments are complete, reinstall the 5 ampere fuse and connect only the power input

leads or PMG leads to the regulator. Remove all other regulator connections that may be present and temporarily

insulate them.

Start and run the generator at rated speed. The regulator will perform the self-test and enter a shutdown mode. At

this time, initial adjustments can be made. To do this, step through each adjustment using the “SELECT” button.

For each adjustment, press the “UP” or “DOWN” button to obtain the desired level on the LED bar graph.
