Woodward 505 Digital Governor Marine/ATEX Compliance LVDC 8200-1302
Description:
8200-1302 is designed as Woodward 505 Digital Governor controller. It can control single or dual (split range) actuator steam turbines. 8200-1302 is situable for  ATEX, Zone 2 Hazardous Location. As a Marine/ATEX Compliance LVDC (18–32 Vdc), 8200-1302 allows a single design to be used in many different control applications and reduces both cost and delivery time. It uses menu driven software to instruct site engineers on programming the control to a specific generator or mechanical drive  application. The 505 can be configured to operate as a stand-alone unit or in conjunction with a plant’s Distributed Control System.

8200-1302 drives one or two steam turbine throttle valves to control one turbine parameter at a time, and if desired, limit turbine operation based on other parameters. The one controlled parameter is typically speed (or load), however, the 505 could be utilized to control or limit: turbine inlet pressure or flow, exhaust (back) pressure or flow, first stage pressure, generator power output, plant import and/or export levels, compressor inlet or discharge pressure or flow, unit/plant frequency, process temperature, or any other turbine related process parameter.

Features:
▪ Integrates field-configurable steam turbine control and operator control panel (OCP) in a single unit.
▪ Features a full graphical operator control panel display and keypad on the front panel.
▪ Supports turbine configuration, online program adjustments, and turbine/system operation via the display.
▪ Enables real-time viewing of actual and set-point values with user-friendly instructions during operation.

Q&A:
1. How to configurate the 8200-1302.
When configurate the 8200-1302, you need to  select the options needed to configure the control to your specific turbine application. While in this mode, the control will force the hardware into IO LOCK, meaning that no outputs will be active, all Relays will be de-energized, and all Analog output signals will be at 0 current. Once the control has been configured, the Program Mode is typically not needed again, unless turbine options or operation changes. It is available to be viewed at any time. A password is required to log into this mode. 

2. What's the warranty period of the module?
Our warranty is 1 year.
