Engine Speed Dial SwitchThe positions of the engine speed dial switch are designed to inform the controller about the speed that is desired by the operator. The engine speed dial switch has ten positions: 1 to 10. Each position of the switch has a unique combination of connector contacts that close to contact 1. A combination of contact 2 through contact 5 will close to contact 1. This switch will ground a unique combination of inputs for the engine speed dial switch to the controller.One Touch Low Idle Switch
The one touch low idle switch is incorporated into the top section of the right joystick. When the switch is in the ON position, the engine speed is decreased to 1100 rpm.Pressure Switch

Travel Pressure Switch And Implement/Swing Pressure SwitchLeft Travel Pressure Switch, Right Travel Pressure Switch, Straight Travel Pressure Switch and Implement/Swing Pressure Switch
The travel pressure switch and the implement/swing pressure switch will monitor the hydraulic system. This switch is normally open. These switches will inform the controller about the status of the hydraulic demands. When there is no hydraulic demand these switches are open. The function of the automatic engine speed control (ECM) of the controller will use these switches to determine operation. These switches are in the normally open position, when the switches are not installed on the machine. The implement/swing pressure switch releases the swing brake. If the implement/swing pressure switch and the travel pressure switch are in the closed position the swing brake will be released.Engine Oil Pressure Switch
Illustration 3 g00662566
Engine Oil Pressure SwitchDuring normal operation, the engine oil pressure switch is closed to ground. This switch is normally open. The switch opens when engine oil pressure is less than the specified value for the switch. If the switch is in the open position, the controller will notify the operator that the engine oil pressure is insufficient. This switch is normally open, when the switch is not installed on the machine. Key Start Switch
Illustration 4 g00291705
Key Start SwitchThe key start switch is an input of the engine and pump controller. The key start switch informs the ECM of an attempt to start the engine. Then, the ECM initiates the start procedure.During normal machine operation, the start terminal of the key start switch is open. If the key start switch is placed in the START position the start terminal will close. +Battery voltage is supplied to the start terminal. When all starting conditions are satisfied, the ECM sends a +battery signal to the start relay and engine cranking begins.Note: After the key start switch is initially turned to the START position, the switch will not return to the START position from the ON position. The switch must be turned to the OFF position first. Then, the switch can be turned to the START position.Air Filter Switch
Illustration 5 g01004714
Air Filter Switch The air filter switch will close, if the air filter is blocked with debris. This switch is normally open. A warning will be displayed on the monitor. However, when a warning of higher priority is occurring at the same time, the warning with the higher priority will be displayed.Hydraulic Oil Filter Switch
When the hydraulic oil filter is clogged, the hydraulic oil filter switch will be open. A warning will be displayed on the monitor. Engine Coolant Level Switch
The engine coolant level switch is an electronic switch that is activated by the coolant. The coolant level switch is closed to ground during normal operation. The switch opens when the coolant level is too low. The open switch informs the controller that the coolant level is too low in the cooling system. Hydraulic Level Switch and Engine Oil Level Switch
Illustration 6 g00662559
Hydraulic Oil Level SwitchThe hydraulic oil level switch monitors the hydraulic oil level after the starter key switch is held in the ON position for 2 seconds or more. The controller checks hydraulic oil level with the switch. The switch closes when the hydraulic oil level is below the normal operating level. This switch is in the normally open position, when the switch is not installed on the machine.Water Separator Level Switch
Illustration 7 g00685243
Water Separator Level SwitchWhen the volume of water that has been separated by the water separator reaches a specified volume, the switch is closed. The controller reads the input from the water separator switch. The controller will display a warning on the monitor. The water separator should be inspected. The water separator should be drained.Switch Panel Assembly
