Introduction
This section contains information on calibrating of the control. This section includes initial settings and adjustments for the start-up. These adjustments are intended to allow starting the engine for the first time.
The engine may overspeed due to incorrect assembly or adjustment.Engine overspeed could result in personal injury, loss of life and/or property damage.Be prepared to stop the engine by activating the engine shutdown system or closing the air inlet lines.
Start-up Adjustments
Complete the installation checkout procedure in this Service Manual, "Installation" and review the settings of the menu in this Service Manual, "Programmable Parameters". Ensure that all critical set points are correct. This includes the following items in "Configure" menu: "CFIG OPTION" and "CFIG SPEED CONTROL". This also includes the following items in the "Service" menu: "1st DYNAMICS", "2nd DYNAMICS" and "SPEED SETTING". All other menu items that are critical to the specific application must also be determined and correctly set.
Open the "Open to Run" contact. Be sure that the "Rated Speed" contact is in the idle position. This is the open position. Apply power to the control. Do not proceed unless the green "POWER OK" and "CPU OK" indicators on the front of the control are on.
Check the speed sensor. Under the following conditions, the red "FAILED SPD SENSOR" will be activated:
the rpm of the engine is less than 5 percent of the rated rpm.
the amplitude of the speed sensor is less than 1.5 Vrms.Note: Before cranking, be sure to prevent the engine from starting.Measure the voltage while you are cranking. The minimum voltage that is required from the speed sensor to operate the control is 1.5 Vrms.If the red "FAILED SPD SENSOR 1" indicator remains on, shut down the engine.
Accidental engine starting can cause injury or death to personnel.To prevent accidental engine starting, turn the ignition switch to the OFF position, place a do not operate tag at the ignition switch location and disconnect and tape the electrical connection to the stop solenoid that is located on the fuel injection pump.
Start the engine.If there is not enough fuel for starting the engine, increase the "Start Fuel Limit". This is in the "Fuel Limiters" menu. The control will reduce the fuel when the speed setting is reached. The control requires extra fuel to accelerate the engine to idle speed. The control may take a few starts in order to determine the final setting of the "Start Fuel Limit".Increase the "Start Fuel Limit" and/or the "Start Ramp Rate" if the start time is excessive.Decrease the "Start Fuel Limit" and/or the "Start Ramp Rate" if the start time is too fast. To determine the final setting of the control, start the engine when the engine is hot and also cold.
Adjust for stable operation.If the engine is hunting at a rapid rate, slowly
