MSLC functions include:

 Selectable for phase matching or slip frequency synchronizing between the

utility and a local bus with voltage matching;

 Automatic system loading and unloading for bumpless load transfer;

 Import/Export level control capability;

 Process control for cogeneration, pressure, maintenance, or other process;

 Proportional loading of associated DSLC controls in isochronous load sharing;

 Adjustable Power Factor control;

 Built in diagnostics with alarm relay driver output;

 Multi-function adjustable high and low limit alarms and adjustable load

switches with relay driver outputs;

 Digital communications network to provide loading and power factor control

of individual DSLC equipped generators;

 Full setup, metering, and diagnostic capability through a hand held

programmer terminal (Figure 1-2).

Introduction

This manual describes the Woodward MSLC Master Synchronizer and Load Control.

Application

The MSLC is a microprocessor-based overall plant load control designed for use

in a system with Woodward DSLC™ (Digital Synchronizer and Load Control)

controls on each generator to provide utility synchronizing, paralleling, loading,

and unloading of a three-phase generating system.
