Galaxy Power System Verification Procedures
Issue 3 January 2008 Introduction 1 - 1
1 Introduction
Overview
This manual provides general verification procedures for inspection and
testing of Lineage Power Galaxy Power System (GPS) products. The
test procedures mentioned in this manual correspond to controller
software version 6.5.
The Lucent GPS family of products is designed to operate
maintenance-free, without the need for any regular adjustments or fine
tuning. The output voltage and current limit are set by the controller, and
the information is sent as a broadcast message to all rectifiers. All the
rectifier outputs will be automatically adjusted to this level; no
individual rectifier level voltage adjustment is required.
If, however, the customer requires any kind of routine verification or
inspection (even though Lineage Power does not recommend it), the
techniques described in this manual may be used as guidelines to test all
the alarms.
The tests described here will simulate various alarm conditions and
verify that the controller functions properly.
The fans used in the 595-Series and 596-Series rectifiers have a typical
lifetime of 7 years. The fans in the 597A and 597B 24V/48V converter
carriers have a typical lifetime of 4 to 5 years. Lucent recommends that
these fans be replaced at these intervals as described in Section 4,
Replacement Procedures in this manual.
Note: Fan assemblies should be kept dust-free at all times. Air flow
through the rectifiers is important for the proper operation of the
rectifiers.
