LINES GP-WATER 1735562 - Caterpillar

of maximum speed, the actual gain will be 25 percent of the set point value and Stability and Compensation values will be two times greater than at maximum speed.The Constant Map provides a Gain which is constant at all engine speeds for some medium- to high-speed engines. Stability and Compensation are also held constant.The final decision on which map to use depends on engine performance obtained throughout the operating speed and load range. After tuning the control for desired performance under rated speed and load conditions, performance at low speed and light loads should be evaluated. If low frequency speed oscillation occurs at low speeds using the Linear Map, the Nonlinear Map will provide additional Stability. If performance is poor at low speed using the Nonlinear Map, the Linear and Constant Maps will provide higher performance. Select the map that provides the best overall performance for all operating conditions.7. MPU1 Failed Alarm sets the alarm condition which will occur when a loss of the speed sensor #1 input signal has been detected. Alarm selection may be Major Alarm, Minor Alarm, or None.8. MPU2 Failed Alarm sets the alarm condition which will occur when a loss of the speed sensor #2 input signal has been detected. Alarm selection may be Major Alarm, Minor Alarm, or None.9. Both MPUs Failed Alarm sets the alarm condition which will occur when a loss of the speed sensor #1 and #2 input signals has been detected. Alarm selection may be Major Alarm, Minor Alarm, or None.10. Load Sensor Failed Alarm sets the alarm condition which will occur when the KW Transducer input drops below 2 mA. Alarm selection may be Major Alarm, Minor Alarm, or None.11. Sequence Error Alarm sets the alarm condition which will occur when a sequence error has been detected. Alarm selection may be Major Alarm, Minor Alarm, or None.12. High Torsional Level Alarm sets the alarm condition which will occur when the torsional Derated Trip Level set point (Menu 4) has been exceeded. Alarm selection may be Major Alarm, Minor Alarm, or None.13. Remote Input Failed Alarm sets the alarm condition which will occur when the Remote Speed/Load Setting input drops below 2 mA. Alarm selection may be Major Alarm, Minor Alarm, or None.Menu 9 - Calibration Menu
Input and output values are displayed once when each item is selected. Woodward Governor Company has done a factory calibration on the control prior to shipment, and it should not normally require field adjustment. See the Control Test and Calibration section in Chapter 7 for proper adjustment procedure.1. Calibration Key is a code which you must enter before you can change any of the set points on the calibration menu. This helps prevent accidental modification of the set points. The code is factory set to "49". Use the "Turtle Up" and "Turtle Down" keys to select the code. Whenever the Minimum Fuel (Run/Stop) input is changed, the code will be reset to "0". The Minimum Fuel (Run/Stop) contact must be open,
