Right Console (1) Display (2) Water spray enable switch (3) Propel leverDisplay (1) and propel lever (3) are located on the right console. Water spray enable switch (2) is located on the propel lever (optional propel lever shown). The water spray enable switch controls the on and off status of the water spray system.Note: The standard propel lever has two switches that control the vibratory and water spray system. The left switch on this propel lever is the water spray enable switch. The water input to the water control logic is the same when the machine is equipped with either propel lever.Propel lever (3) communicates with the machine ECM through the CAN.Water spray enable switch (2) is momentary and operates only when the engine start switch is in the ON position. Each time the operator presses the water spray enable switch an input signal is sent to the machine ECM. The machine ECM toggles the status of the water system between off and on with each input signal. A green indicator on the left side of display (1) indicates that the system is on. The machine ECM illuminates this indicator.If water spray enable switch (2) is held for more than 2 seconds, water will continuously spray. After the water spray enable switch is released, the water timer will return to the previously set water spray percentage.The fault indicator is located on display (1). This indicator alerts the operator to faults in monitored systems. The machine ECM monitor circuits and components in the water spray system for faults. When a fault is detected, the machine ECM illuminates the fault indicator. Service technicians must use an electronic service tool to retrieve fault information.

Right Console (4) Keypad (5) Timer decrease switch (6) Timer increase switch (7) Spray mode switchKeypad (4) is located on the right console. The keypad contains the following water system switches:
Timer decrease switch (5)
Timer increase switch (6)
Spray mode switch (7) Each of the above switches provides an input signal to the machine ECM through the CAN. The machine ECM uses the input from these switches in order to determine the desired operating conditions for the water spray system.The switches on keypad (4) operate the water spray system. Spray mode switch (7) toggles between pump "1" mode, pump "2" mode and the automatic mode. The timer switches allow adjustment of the water spray interval.The indicators next to spray mode switch (7) illuminate the currently selected water spray mode. Only the bottom indicator is illuminated when the system is operating in the pump "1" mode. The middle indicator is illuminated when the system is operating in the pump "2" mode. The top indicator is illuminated when the automatic spray mode is selected.The water spray mode will also be shown on display (1) every time spray mode switch (7) is depressed. This pop up display will disappear after 3 seconds. Five seconds after the last switch was pushed the operational state will be saved into memory. This operational state
