Woodward UG40-DI Governor / Installation and commissioning manual
Language: english Author: Woodward Genre: Manual Format: PDF Quality: eBook Number of pages: 66 Description: This manual is applicable to the UG40-DI Governor and describes its mechanical and electrical installation, operation and set-up. It is arranged in ten chapters: - GENERAL INFORMATION - ESD PROTECTION AND HANDLING - DESCRIPTION - INSTALLATION - GOVERNOR MECHANICAL OPERATION AND ADJUSTMENTS - CALIBRATION OF THE DIGITAL INTERFACE - ADJUSTMENT OF THE DIGITAL INTERFACE - ALARMS, DIAGNOSTICS AND SERIAL COMMUNICATIONS - TROUBLESHOOTING AND REPAIRS. The UG40-DI is a mechanical-hydraulic governor with a digital interface for controlling diesel engines. The UG40-DI uses a 250 PSI oil supply and is mechanically linked to the fuel racks. The maximum travel of the output (terminal) shaft is 38°, and the recommended travel of the output shaft is 25° from no load to full load (refer to Section 4.5 for more details). Normally, the UG40-DI operates isochronously (constant speed) regardless of load on the engine, except during operation as described in Chapter 3. DESCRIPTION. Speed droop is incorporated in the UG40-DI to divide and balance load between units driving the same shaft or paralleled in an electrical system. A load limit control is also a standard feature on the UG40-DI. It limits the amount of fuel supplied by restricting the travel of the governor output shaft. An indicator dial shows the governor output shaft limit position. The load limit control may also be used for manually shutting down the engine.
