Procedures
Introduction
The procedures in this section may be used to test the different alarms in
a live Galaxy SC Controller system. The procedures are the same for
both rear access and front access Galaxy SC controllers.
Tools
The following tools are required 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
Before performing the test procedures, verify that the following
conditions exist:
• All rectifiers are functioning properly.
• Plant batteries are fully charged and are ready to support a load.
(See Caution below.)
Caution: When Alarm Tests are performed on a live plant, some of
the tests will cause a battery discharge to occur. In this case, ensure
that the plant batteries are capable of supporting the load. It is
recommended that a battery discharge test be performed before
proceeding with other tests.
Follow the steps of the procedures in the order they are given.
