2301E 8273-1011 WOODWARD Debugger unit

The 2301E 8273-1011 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 2301E 8273-1011
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:
- 2301E 8273-1011 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.

Processing method:

a、 If possible, turn the position feedback polarity switch to another position. (Can be used on some drives)

b、 If using a speedometer, swap and connect TACH+and TACH – on the driver.

c、 If using an encoder, swap and connect ENC A and ENC B on the drive.

d、 In HALL speed mode, swap HALL-1 and HALL-3 on the drive, and then swap Motor-A and Motor-B together.

Reason for malfunction: During encoder speed feedback, the encoder power supply lost power.

Solution: Check the connection of the 5V encoder power supply. Ensure that the power supply can provide sufficient current.

If using an external power source, ensure that the voltage is connected to the driver signal ground.

4. The LED light is green, but the motor does not move.

Reason for malfunction: The motor in one or more directions is prohibited from operating.

Solution: Check the+INHIBIT and – INHIBIT ports.

Reason for malfunction: The command signal is not grounded to the driver signal.

5. After power on, the LED light of the driver does not light up.

Reason for malfunction: The power supply voltage is too low, below the minimum voltage requirement.

Solution: Check and increase the power supply voltage.

6. When the motor rotates, the LED light flashes.

Reason for malfunction: HALL phase error.

Solution: Check if the motor phase setting switch (60/120) is correct. Most brushless motors have a phase difference of 120.

Reason for malfunction: HALL sensor malfunction

Solution: When the motor rotates, detect the voltage of Hall A, Hall B, and Hall C. The voltage value should be between 5VDC and 0.

Solution: Connect the command signal ground to the driver signal ground.
