EASYGEN 2500 Woodward overspeed protector

The EASYGEN 2500 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward EASYGEN 2500
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- EASYGEN 2500 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

Input/output pins

You can see that there are 14 instructions related to I/O pins in BS-1. The reason for emphasizing this point is

that the input-output pins are the only way for BASIC Stamp to communicate with the outside world. BS-1 has 8 input/output pins

(numbered 0 to 7), and BS-2 has 16 input/output pins (numbered 0 to 15).

These input and output pins are bidirectional, which means that input values can be read from the pins and output through

the pins. The easiest way to send values to a pin is to use the HIGH or LOW command. Using the statement “high 3” can emit a

1 (+5 volts) on pin 3, while using “LOW” will emit a 0 (ground). The third pin here can be selected arbitrarily – you can output level signals to any pin from 0 to 7.

There are many interesting instructions about input and output pins. For example, if you follow the POT instruction to connect a

capacitor in parallel across a potentiometer (variable resistor), the POT instruction can read the potentiometer settings. PWM commands

can emit modulation signals with pulse width. Adding control and driver functions to Stamps is much easier with instructions like this. For

detailed information about language, please refer to the documentation. In addition, books such as Scott Edward”s Programming and Customizing

the BASIC Stamp Computer, which contain a large number of example projects, are also extremely beneficial.

Practical operation of BASIC Stamp

If you want to actually operate BASIC Stamp, it is very easy to get started. All you need is a desktop computer and a BASIC Stamp starter kit.

The introductory toolkit includes a Stamp microcontroller, programming cable, and an application running on a desktop computer that downloads BASIC programs into Stamp.
