Woodward Vertex‐Pro Motor‐Driven Compressor Control

Description

The Vertex-Pro is an anti-surge controller, designed to control and protect industrial-sized

motor-driven axial and centrifugal compressors. This purpose-built controller is available

in standard off-the shelf models or custom models. Standard off-the-shelf models are available

for one or two recycle loop applications, while custom models (Vertex-Pro-C models) are available

for larger three and four recycle loop applications.

OEM-qualified algorithms are used to ensure that proper start sequences are followed,

proper and accurate compressor load calculations are used, and proper protection and

recovery actions are performed.

Basic functionality includes:

 Motor Drive Interface Logic

 Inlet Throttle Valve Control

 Inlet Guide Vane Control

 Recycle Valve(s) Control

 Surge Control

 Performance Control (suction or discharge)

 Surge Anticipation Logic

 Surge Protection Logic

 Surge Recovery Logic

 Load Sharing

The Vertex-Pro is built on Woodward’s field-proven MicroNet™ platform, and is available in simplex

or dual redundant models. All models utilize the MicroNet’s compact 8-slot chassis and

robust field termination modules. Simplex models include one of every module, while

dual-redundant models include two of every module, allowing users to perform both

bumpless on-line program changes and on-line module replacements.

The Vertex-Pro chassis is designed to be bulkhead-mounted in a cabinet or control

panel, and contains the required I/O and core control software to control industrial

motor-driven compressors. Typically, this controller is located in an enclosure that is

rated for the site-specific environment. Field termination modules (with integrated

circuit fuse protection) are included with this controller to allow users to easily land

and manage compressor and system interface wiring. The control also supplies

source power for associated sensors and I/O circuits.

This control is field-configurable, allowing users to easily configure the control to

application-specific requirements.

A menu-driven software program (Control Assistant) is provided with the control,

and when installed on any Windows based computer or laptop, serves as the human

interface to the control and or compressor.

This Control Assistant is used to configure, service, and optionally operate the control.

Optionally a touchscreen OpView™ panel is available for use as a local or remote

operator control panel. This OpView panel is comprised of a 307 mm (12.1”) touchscreen 

computer, and connects to the control via an Ethernet link.
