ADJUSTING FOR STABILITY

Once the engine is running at operating speed and at no load, the following

governor performance adjustments can be made to increase engine stability.

GAIN - RATED SPEED & IDLE SPEED

The EEG6500 is equipped with two separate gains, one for rated

NOTE

speed, the other for idle speed. Both are set using the GAIN set-

ting on the Quikset menu.

GAIN TYPE

Selected when IDLE input is disconnected.

RATED SPEED

Connect the idle input to ground.

IDLE SPEED

Change GAIN value.

Disconnect Idle input from ground to switch back to Rated.

Idle icon will blink.

NOTE

PARAMETER

Increase this parameter until instability develops.

Then, gradually decrease this parameter until stability returns.

GAIN

Finally, decrease this parameter one increment further to ensure

stable performance.

If instability persists, adjust the next parameter.

Follow the same adjustment procedure as the GAIN parameter.

STABILITY

If instability persists, adjust the next parameter.

If fast instability occurs, switch DEADTIME to low and repeat

DEADTIME

steps A & B.

Normally, adjustments made at no load achieve satisfactory per-

NOTE

formance. For further performance, refer to sections (10) & (11).

ADJUSTING FOR DROOP

After the initial set up is completed and the # of Teeth, Crank Termination

Speed and Rated Speed are set, position the external switch connecting

terminals 'H' and 'K' on to activate the DROOP mode following these sequence

steps.

Go to the Advanced menu: Press and hold all three buttons simultaneous-

ly for two seconds to switch to Advanced Menu.

Confirm that the VSPD (Variable Speed / Fixed Speed Control) is off.

Default position is off.

Confirm that the LEAD circuit is off. Default position is ON.

Set the NLCU (No Load Current) to the measured / displayed current

value when operating at no load rated speed (default value is 0.5 amps.)

Set the FLCU (Full Load Current) to the measured / displayed current

value when operating at full load rated speed (default value is 4.0 amps.)

Return to the Main Menu: Press and hold all three buttons simultaneously

for two seconds to switch to the Main Menu.

Select and set DROOP to the desired percentage.

Change the Speed parameter, which turns into the 'DROOP OFFSET'.

This sets the RPM, above operating speed, to which the system will be

commanded when DROOP is enabled. This is an offset value.

1500 RPM operating speed x 0.05 (5.0% droop) = 75 RPM

EXAMPLE

Input 75 RPM, this is the offset value.

The NLCU entered must be less than the FLCU and the differnece between

the two must be at least 0.5A. If an invalid combination is entered a warning

will be flagged and the parameters will be default to 0.5A and 4.0A.
