10. Acceptance Testing

The Galaxy Millennium Controller is tested before it leaves the factory, but many users wish to add

some test procedures as part of installation and turn-up. The tests described here will simulate various

alarm conditions and verify that the controller functions properly. Follow the steps listed below in the

order they are given.

Tools and Test Equipment Required for Acceptance Testing

Digital Voltmeter (DVM) with dc accuracy of at least 0.05%

Short length of wire or clip lead for jumper

Jeweler's screwdriver

Follow these steps to test plant alarms when installing the Galaxy Millennium Controller in a new plant. In a new

installation, begin the sequence with the rectifiers

running with a dummy load on the plant bus bar.

For these tests, it is assumed that:

•

All rectifiers are functioning properly.

•

Plant batteries have received their original charges and are ready to support a load.

If you are testing a controller in a live plant:

•

Some tests will cause a battery discharge. Insure that plant batteries are capable of supporting the load.

•

Alarms will be generated. Notify the appropriate alarm monitoring personnel.
