functions properly. Follow the steps listed below in the order they are given.
Tools and Test Equipment

Test Precautions
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.
