Start and stop generator automatically

Start and stop generator automatically

Start and stop generator automatically

Hi folks
I need a wiring diagram for start and stop 70kva generator with using motorized changeover switch.
The generator is with out an advanced controller.

RE: Start and stop generator automatically

What a coincidence.
I need a part for a 35 year old 120HP farm tractor.
Can you help?
No need to post any more information. You all know what I mean.

RE: Start and stop generator automatically

This should do, based on the information provided.

RE: Start and stop generator automatically

Sounds like you need an advanced controller.

RE: Start and stop generator automatically

I need a set of brushes for a motor.

RE: Start and stop generator automatically

If this is a DIY project, don't, hire a professional. You can't do this online.

If it is an already existing system and you want the schematics, contact the oem/supplier/contractor since they are custom designed.


RE: Start and stop generator automatically

The circuits are most likely part of the proprietary generator control board. Rather than supply component level diagrams for repair, the manufacturer will rather sell you a replacement module or circuit board. It will include a diagram for the field wiring (Two wires) but not enough information for component level repairs.

RE: Start and stop generator automatically

I am sorry for this mess.that was my ability to describe my inquiry.
If you do not get my meaning you easly ignore this post .
Thanks for all .that was very helpful.

RE: Start and stop generator automatically

Consider adding some detail to your question, such as

(1) The brand and model of your generator.

(2) The brand and model of the switch you have.

(3) The voltage of the system.

(4) Do you have the needed expertise and resources to install a controller?

RE: Start and stop generator automatically

Most Generator dealers have available accessory control panels that can help you with this simple function.

You can also have a neighborhood UL508 panel shop build you a automatic panel based on the parameters you prefer to use for automatic start or stop. Most common parameter is current draw or demand. When current draw on the system exceed x-amount then generator starts and goes on line parallel to existing system. When demand reduces to x-amps then generator drops off.

If you are remote and running pumps or similar load you could base on a timer function or water or air pressure call ups to automatically start/stop your generator.

There is also exerciser panels that come on every Friday and run for an hour and then shut down. Time and day frequency vary to your choice.

Hope this helps with some research ideas.
