Chapter 5.
Initial Control Settings
Initial Prestart Settings
Read this entire procedure before starting the prime mover.
1. The Toolkit Service Tool contains a First Time Configuration Wizard which
will step a user through all of the initial settings. This is explained in Appendix
“F”.
2. RATED SPEED
—Set to Generator synchronous speed.
3.
Set the correct number of gear teeth in “Enter number of gear teeth”.
4. Select the proper speed function.
5. Set the overspeed setting, usually 110 to 115% of the rated speed. Make
sure that there is always a separate overspeed detection device to protect
the engine form overspeed!
6. For initial startup, configure the control for single slope gain dynamics. Turn
off DYNAMICS 2, use only Dynamics 1 adjustments for initial startup.
7. IDLE PROP GAIN
– Set at 1.0
8. RATED PROP GAIN 1
—Set at 2.0.
9. RESET 1
—Set at 1.0.
10. ACTUATOR COMPENSATION 1
—Set the ACTUATOR COMPENSATION at
0.1 for diesel or fuel injected gasoline prime movers. Set the ACTUATOR
COMPENSATION at 0.35 for carbureted gas or gasoline prime movers.
11. Set GAIN RATIO 1 to 1.0 to disable the effect of window width and gain ratio.
12. ACCEL RAMP TIME
—Set at 20 sec.
DECEL RAMP TIME
—Set at 20 sec.
13. LOW IDLE SPEED
—Set at idle speed rpm, (no lower than 20% of rated).
14. LOAD GAIN
—Set at 1.0, or the value of other load sharing controls on a
common bus.
15. DROOP
—Set at desired percentage.
16. START FUEL LIMIT
—Set at 100%.
17. Be sure the actuator is connected to terminals 13 and 14 and the speed
signal connected to terminals 25 and 26.
Start-up Adjustments
1. Complete the Configuration Procedure in Chapter 4, or the First Time
Configuration Wizard in Appendix “F”, or the initial prestart settings above.
Be sure the Rated Speed and Number of Teeth are set correctly for
your application as described earlier in this chapter.
2. Close the
“Close For Rated” contact. Set the control for isochronous
operation by closing the droop/CB Auxiliary and the generator Load contact.
This is for initial prime mover start-up only. For normal start-up, the
Close for Rated contact (open for idle/close for rated) should be open
if the prime mover is to start at idle.
