ASCO 7000 SERIES Power Control System

Introduction

Illustrative sequence and timing. Actual operation depends on the project configuration.

1. Power fails

   Utility power to the facility is lost.

Guided tour

1. What am I looking at?

   See system information in one place.

   The touchscreen brings together access to synchronizer and load-share controls, controllers, meters and circuit-breaker information. One-line diagrams show system status.

   Interface and equipment configuration depend on the project.

2. Where are the generator controls?

   Find the generator operating controls.

   Generator control sections include manual controls for engine-generator testing and selection of operating modes.

   The final controls and labels depend on the configured project. This is an explanatory view.

   Learn more

   Generator control stations provide local manual testing controls alongside the system’s automatic functions.

3. How are generators connected to the system?

   Explore a visible breaker location.

   Generator paralleling breakers connect generators to the common bus within the configured operating sequence.

   The highlighted exterior face is an explanatory location. Its rating and assigned circuit must be confirmed from project drawings.

   Learn more

   The PCS combines breaker operation with synchronization and load management as part of the system sequence.

   First connection to an unenergized bus

   The cited learning example connects one generator first to an unenergized bus. Other generators synchronize before connecting to the energized bus.

   Illustrative sequence. Controls and configuration depend on the project; pictured circuit assignments require confirmation.

   Illustrative draw-out view

   The cited low-voltage guide describes draw-out generator breakers with connected, test and disconnected positions.

   Explanatory movement of exterior representations. Confirm installed devices, mechanism travel and project details from the project documentation.

4. How is power connected?

   Follow the shared power path.

   The bus connects source and load circuits. The product family offers several bus configurations to suit the application.

   The painted route is illustrative, not a wiring drawing. Bus ratings and segmentation depend on the configured project.

   Learn more

   Available bus arrangements provide different source and load connection paths; selection depends on the facility’s requirements.

5. What manual controls are available?

   Understand the manual paralleling path.

   Manual paralleling allows generators to be connected to the main bus if automatic paralleling becomes inoperable.

   Hardwired manual paralleling is standard in the low-voltage product family. The arrangement depends on the project.
