Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Acceptance Testing 5 - 1
5 Acceptance Testing
Introduction The Galaxy SC 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 as installed.
Follow the steps listed below in the order they are given.
Tools and Test
Equipment
You will need these tools to complete the tests described in this section:
• Digital Voltmeter (DVM) with dc accuracy of at least 0.05%
• Short length of wire or clip lead for jumper
• Jeweler’s screwdriver
Precautions Follow these steps to test plant alarms when installing the Galaxy SC 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 replacing a controller in a live plant, recognize that some tests
will cause a battery discharge to occur. Insure that plant batteries are
capable of supporting the load.
Lamp Test Depress the <LAMP TEST> key on the Galaxy SC Front Display
interface. See Figure 2-3. All Front Panel and board LEDs will operate
momentarily and then retire.
