5415-623 Woodward Ship Spare Parts

The 5415-623 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 5415-623
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:
- 5415-623 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.

In the following program, BASIC Stamp performs a clock function by outputting time through the LCD screen (assuming the

LCD screen is connected to the Stamp input/output pin 0):

Paul 1000 “Wait for the LCD screen to start serout 0, n2400, (254, 1)” Clears the display of serout 0, n2400, (“time:”) The screen

shows “time:” “Preset before loading the program b0=0” seconds b1=27 “minutes b2=6” hours again: b0=b0+1 “seconds plus 1 if b0” 60 then

minutes b0=0 “If the seconds are equal to 60 b1=b1+1”, then the minutes plus 1 minute: if b1 “60 then hours b1=0” If the minutes are equal to 60

b2=b2+1 “, then the hours plus 1 hour: if b2 If the number of hours is equal to 13, reset to 1 show: show 0, n2400, (254135) “Position the cursor on the

display screen,” and then display the time serout 0， n2400，（#b2， “：”， #b1， “：”， #b0， “ ”） pause 950 ‘ Pause 950 milliseconds goto again “repeat

In this program, data is sent to the LCD screen through the SEROUT command. The sequence (254, 1) is used to clear the LCD screen, where 254 is

the escape character and 1 is the command to clear the screen. The sequence (254135) is used to locate the cursor. The other two SEROUT commands

only send text strings to the display screen.

This method will result in a relatively accurate clock. By adjusting the PAUSE statement, the daily error can be controlled within a few seconds. Obviously,

a real clock requires one or two buttons to calibrate the time – in this program, you need to pre-set the time before loading the program into the Stamp.

This method is simple and effective, but not very accurate. If you need to improve timing accuracy, connecting a real-time clock chip to the Stamp is a good choice.

In this way, the time will be read from the chip and displayed every second or so. Quartz crystals are used in real-time clock chips to achieve excellent accuracy.

Clock chips usually also contain date information and can automatically perform leap year correction.
