The information is then sent to the Governor Actuator (70) in order to control engine speed.The engine speed dial (14) is divided into 10 positions. The dial position is displayed on the character display of the monitor panel. The speed of the engine with no load for each dial position is shown in the following chart.Table 1RPM For The Engine Speed Dial Switch320D, 323D"Dial Position" Engine RPM Hyd Torque (%)1 1000 202 1100 403 1200 604 1300 81.25 1470 86.46 1590 86.47 1700 86.48 1800 86.49 1900 86.410 1980 100Self-Diagnostic FunctionThe machine ECM, callout (12) is self-diagnostic. The machine ECM monitors the inputs and the outputs. The machine ECM also monitors for system problems that occur or system warnings that are generated during operation. The machine ECM will display a system warning that is generated or a problem that has been detected via the self-diagnostic function, on the monitor, callout (32). Refer to illustration 2.Note: A log file is kept for the warnings. The log file contains the time and the number of occurrences of each warning.Automatic Engine Control (AEC)View ImageIllustration 3g01227345 (1) Switch Panel(12) Machine ECM(14) Engine Speed Dial(17) No. 1 Pump Pressure Sensor(18) No. 2 Pump Pressure Sensor(19) Implement Pressure Switch(20) Travel Right Pressure Switch(21) Travel Left Pressure Switch(29) Straight Travel Pressure Switch(70) Governor ActuatorThe AEC will lower the engine speed if no load on the machine continues for approximately five seconds or a light load on the machine continues for ten seconds when the engine speed dial is set in a position of 5 to 10. This process is designed to reduce the noise and fuel consumption. The AEC has settings in two stages. The AEC can be set by the switch on the right console. The indicator of the switch will illuminate during the second setting of the AEC. The second setting of the AEC is available immediately after the engine start switch is turned to the ON position. The AEC can be set in the first stage and the second stage by alternately pressing the switch.First Setting Of The AECThe first setting of the AEC will lower the speed of the setting of the engine speed dial by approximately 100 rpm in the "no load" or the "light load" condition.Second Setting Of The AECThe second setting of the AEC will reduce the engine speed to approximately 1300 rpm in the "no load" condition.Note: When the main backup switch (22) is turned to the ON position (Manual), the AEC function is disabled.One Touch Low IdleView ImageIllustration 4g01227889(12) Machine ECM(14) Engine Speed Dial(15) One Touch Low Idle Switch(17) No. 1 Pump Pressure Sensor(18) No. 2 Pump Pressure Sensor(19) Implement Pressure Switch(20) Travel Right Pressure Switch(21) Travel Left Pressure Switch(29) Straight Travel Pressure Switch(70) Governor ActuatorWhen the one touch low idle switch (15) is pressed and the machine is not under a load, the engine speed can be lowered by more than the speed of the setting of the second stage of the AEC. When normal operations have resumed, the engine speed for the dial setting will return the corresponding RPM.Start-up Of The One Touch Low IdleThe one touch low idle feature will activate during all "stopped" conditions of the implement, swing, travel and tools. The following components are in the OFF position: implement swing pressure switch, the travel pressure switch (right), the travel pressure switch (left), the attachment (ATT) pedal pressure switch and the straight travel pressure switch. However, when the one touch low idle switch is pressed, the control will lower the engine speed to the speed of the "2" setting of the engine speed dial to approximately 1020 rpm. This control overrides the AEC.Release Of The One Touch Low IdleThe one touch low idle will be released when any of the following conditions occur: z The one touch low idle switch (15) is pressed again.z The implement swing pressure switch is set to the ON position.z A travel pressure switch is set to the ON position.z A pressure switch that is related to a tool is set to the ON position.The engine speed is different after the switch has been released. The different speed will depend on the conditions of the release.1.The engine speed will be set to the setting of the engine speed dial, when the feature for onetouch low idle has been released by an operation of the implement, swing, etc..2.The engine speed will be set by the AEC. The speed will be set when the one touch low idlehas been released. The engine speed will be affected by the following conditions:a.When the first setting of the AEC is selected, the engine speed will be set to the speed ofthe first setting of the AEC. The speed is approximately 100 rpm lower than the settingof the engine speed dial.b.When the second AEC is selected, the engine speed will be set to the speed of the settingof the second AEC. The speed is approximately 1300 rpm.c.The engine speed will be set to the speed of the engine speed dial if the engine speed islower than the setting of the second AEC. The setting of this speed is not based on asetting of the AEC.Engine Speed ProtectionView ImageIllustration 5g01227890(12) Machine ECM(16) Speed sensor(32) Monitor(35) Alternator(44) Engine Oil Pressure switch(70) Governor ActuatorPrevention of Overspeed During Low Engine Oil PressureThis function is designed to prevent the engine from starting at a high speed during a condition of low oil pressure. After the engine oil filter is replaced, a long time may be required before the engine oil pressure will reach the specified level. Engine damage may occur if the engine runs at the speed dial position of 10. The following information describes this function.The engine speed will be limited to the position of 5, if the engine oil pressure switch is open. The engine will start at the speed of the 5 position.Prevention Of Overspeed During Overheating ConditionThis function is designed to prevent damage to the engine that is caused by overspeed during anoverheating condition. Work that requires high pressure will be restricted during an overheating condition. The engine and other components are protected during this condition. The engine speed will be decreased to the second setting of the AEC (1300 rpm).Control Of The Hydraulic Oil At Low TemperaturesWhen the conditions of the climate are cold and the temperature of the hydraulic oil is low, the machine may not operate smoothly. The output of the pump will decrease by a small amount. This allows the operations to be smoother until the temperature of the oil rises. When the hydraulic oil temperature sensor has detected an oil temperature below 15 °C (59 °F) the system limits hydraulic pump output pressure to 80% of maximum hydraulic horsepower. When the hydraulic oil temperature sensor detects an oil temperature that has risen above 20 °C (68 °F), normal control of the hydraulic oil will begin again.Pump RegulationView ImageIllustration 6g01229125 (12) Machine ECM(14) Engine speed Dial(16) Speed Sensor(17) No. 1 Pump Pressure Sensor(18) No. 2 Pump Pressure Sensor(25) Power Shift Pressure Proportional Reducing Valve(32) Monitor(34) Hydraulic Oil Temperature Sensor(70) Governor ActuatorThe Machine ECM (12) determines the power shift pressure for regulating the pumps based on the following: position of the Engine Speed dial (14), the pump delivery pressure and engine speed.When the power shift pressure is high, the pump output decreases. When power shift pressure is low, the pump output increases. Pump control is in Constant Horsepower Control mode when the Engine speed dial (14) is set on positions "1" to "9". Pump control is in Underspeed Control mode when the Engine speed dial (14) is set on position "10".Constant Horsepower ControlConstant control of the horsepower is associated with the 1 to 9 setting of the engine speed dial. The flow of the pump is controlled by the power shift pressure when the engine speed dial is in the 1 through 9 position. The hydraulic output will be set according to the position of the engine speed dial. Even though the pump is delivering the maximum flow, the machine ECM will correct the power shift pressure in order to maintain the maximum amount of flow. During the delivery of middle pressure and high pressure, the horsepower of the main pump is controlled in order to prevent high horsepower of the pump with lower engine horsepower. The machine ECM receives feedback from the engine speed sensor. The power shift pressure is proportional to the target flow. The target flow is calculated from the setting of the engine speed and the pressure of the delivery pump pressure sensor. Thus, the power shift pressure will vary according to the position of the engine speed dial and the pressure of the delivery pump. The antistall feature for the engine is used in order to prevent the engine from stalling. The antistall feature will be activated, if the speed of the engine decreases 250 rpm below the position of the dial in comparison to the setting of the engine speed dial.The power shift pressure is fixed for the positions of 1 through 9. The positions of 1 through 4 of the engine speed dial have a different power shift pressure for each setting. The engine speed dial will set the desired RPM, which will produce the desired flows. The positions of 7 through 9 of the engine speed dial have a common power shift pressure that is fixed. The positions 1 through 9 use engine speed, the position of the engine speed dial, and the pump pressure to set a fixed output. The output is fixed until a decrease of 250 RPM below the target RPM. At a RPM of 250 below the target RPM, the engine ECM will adjust the power shift pressure in order to maintain engine RPM within 250 RPM of the target RPM.Underspeed ControlThe underspeed condition is associated with a position of 10 of the engine speed dial. The 10 position of the engine speed dial is used when a large amount of horsepower is required or a high travel speed is requested. In this case, it is necessary to utilize the underspeed feature when the engine is being operated at a maximum horsepower. The underspeed feature will maintain the speed of the engine at approximately maximum power. The machine ECM reads the engine speed and the machine ECM will adjust the power shift pressure in order to regulate the engine speed. The machine ECM controls the power shift pressure in the underspeed condition. The engine maintains a speed of approximately 1800 rpm in order to achieve the maximum horsepower. Therefore, when the engine speed is higher than the full load speed, the output of the pump will increase and the power shift pressure will decrease. Also, when the engine speed is lower than the target speed, the output of the pump will decrease and the power shift pressure will increase.The horsepower of the engine may decrease under the following conditions:z The engine becomes worn.z The quality of the fuel is poor.z The engine is operating at a high altitude.The machine ECM will decrease the output of the pump and the machine ECM will increase the power shift pressure in order to reduce the load on the engine without reducing the engine speed. This condition occurs if the speed of the engine decreases below full load speed.Cooling Fan ControlView ImageIllustration 7g01227901 (12) Machine ECM(14) Engine Speed(27) Viscus Clutch(30) Ambient Temperature Sensor(32) Monitor(34) Hydraulic Oil Temp Sensor(43) Engine Coolant Temperature Sensor(70) Governor ActuatorThe cooling fan speed is controlled by the machine ECM. The machine ECM detects the temperature of the hydraulic oil, the temperature of the engine coolant and the ambient temperature. A target speed for the cooling fan is assigned for each engine speed based on the temperature of the hydraulic oil and the engine coolant. The engine speeds are listed with NO load.Travel Speed - Hydraulic Circuit Change ControlView ImageIllustration 8g01229369(1) Switch Panel(12) Machine ECM(17) No. 1 Pump Pressure Sensor(18) No. 2 Pump Pressure Sensor(20) Travel Right Pressure Switch(21) Travel Left Pressure Switch(24) Travel Speed Change Solenoid(29) Straight Travel Pressure SwitchAutomatic Travel Speed ChangeThere are two travel speed modes, low-speed (tortoise) and high-speed (rabbit). By selecting the "tortoise" mode, travel speed is limited to the low travel speed. By selecting the "rabbit" mode, travel speed will change automatically between low/high speeds. The change in travel speed is dependent on the delivery pressure of the pump.View ImageIllustration 9g01159856Travel Mode selector switch on Switch PanelTravel Mode selector switch- The travel mode selector switch and travel mode indicators (tortoise and rabbit) are located on the switch panel. When the travel mode selector switch is pressed, the travel mode can be set to the rabbit mode or set to the tortoise mode. The indicator (tortoise or rabbit) will be illuminated in order to show the travel mode that is chosen.Automatic travel speed change function- The travel speed will automatically be set to the LOW (tortoise) speed when the machine is first turned on. In order to select the HIGH (rabbit) speed mode, press the Travel Mode selector switch. While the circuit pressure at the pump output remains below a certain range, the machine will travel in the HIGH (rabbit) speed. The output pressure of the pump increases as the load on the machine increases. When the output pressure increases to a certain high level, the machine will automatically shift to travel in the LOW (tortoise) speed mode. The machine will automatically return to the HIGH (rabbit) speed mode when the pump output pressure decreases to the predetermined range.The Automatic travel speed change function allows the machine to adjust speeds without direct operator input. The machine will travel at HIGH (rabbit) speed under a light load. The machine will travel at LOW (tortoise) speed under a heavy load. This ensures that the machine has high mobility and a high drawbar pull.The travel speed will remain in LOW (tortoise) speed mode while the machine is in the heavy lift mode.When the travel is set to the tortoise mode, the travel is set at low speed and does not change. Swing Brake OperationView ImageIllustration 10g01229401 (1) Switch Panel(9) Fine Swing Switch(12) Machine ECM(19) Implement Pressure Switch(23) Swing Brake Release Solenoid(45) Hydraulic Activation Control Lever (Unlocked Position)(46) Hydraulic Activation Control Solenoid(47) Pilot Pressure for Swing Brake Release(48) Fine Swing SolenoidThis machine is equipped with a swing lock system that is hydraulically controlled. The swing lock system control circuit provides control for the swing motor, swing brake, fine swing function and backup system of the machine.The "swing brake release" is controlled by the hydraulic activation lever (45). When the hydraulic activation control lever (45) is moved to the locked position, the swing brake is applied. The swing brake solenoid is energized in order to release the swing brake. The swing brake solenoid (23) is de-energized approximately 6.5 seconds after all levers and pedals are returned to NEUTRAL position.The swing brake is released immediately on the operation of any of these: boom, stick, bucket, swing and an attachment.If the main backup switch is placed in the Manual position, then the swing brake is electrically released.The fine swing function (optional) is designed to open a hydraulic circuit between the A and B ports of the swing motor for smooth start and stop operation in swing movement.The machine ECM detects operation of the fine swing switch in order to release the swing brake.Heavy Lift Mode (Optional)View ImageIllustration 11g01227902(1) Switch Panel(12) Machine ECM(25) Power Shift Pressure Proportional Reducing Valve(28) Heavy Lift Solenoid(70) Governor ActuatorView ImageIllustration 12g01256281Heavy Lift Mode switch on Switch PanelRefer to illustrations 11 and 12. Press the "Heavy Lift" switch on the "Switch Panel", in order to turn the heavy lift mode ON or OFF. When the heavy lift mode is turned ON, the indicator will illuminate. When the heavy lift mode is turned ON, the main relief pressure increases from 35 MPa (5100 psi) to 36 MPa (5200 psi). However, due to the flow restriction, the maximum engine speed is limited at the speed equivalent to engine speed dial position 6 which is approximately 1600 rpm. The hydraulic output is restricted at 64%.Tool ControlWhen an attachment tool is being operated, the engine speed and the pump flow are controlled according to the type of tool. For more information, refer to the appropriate service manual for the tool control of the machine that is being serviced.Selection Of A ToolThere are five preprogrammed tools. The operator selects the tool. The monitor is used to make the selection. The following items are examples of some parameters which can be adjusted in order to。
