Introduction
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
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
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.
