Introduction
This manual should provide you with all the information that you need to safely setup and operate
ASCO Sigma LT load banks.
The manual is divided into five chapters:
In addition to these five chapters there are a number of Appendices containing information that did
not fit easily within the main body of the text. These include installation drawings, a certificate of
conformity and some information about electromagnetic compatibility.
Chapter One
provides an introduction to the general principles of power supply testing
and explains how a ASCO load bank makes the process easier, safer and more reliable.
It then provides an introduction to Sigma LT load banks and its main features.
Chapter Two
covers all of the procedures that need to be carried out before a load
bank can be put into operation. It explains how to transport and setup the unit safely
and then how to commission it to check that it will operate correctly.
Chapter Three
provides an overview and instructions on correct operation of a Sigma
LT load bank using the digital toggle switches.
Chapter Four
provides detailed instructions and reference for controlling a Sigma LT
load bank with the hand-held control.
Chapter Five
covers the maintenance procedures you will need to follow to keep a
Sigma LT load bank operating correctly. It also explains how to troubleshoot should a
problem occur.
