OPERATORS MODE 1. Contrast 2. Brightness



Select 01 or 02 and then use up/down buttons to adjust the screen.



OPERATORS MODE Depending on whether the service attachment is activated the working mode display can show either the mode only or the attachment symbol with the mode. This is displayed in the top left hand corner of the screen.



OPERATORS MODE The top three symbols are displayed next to the gauge displays These can be either white if the level is low or red if the level is too high The other symbols are shown initially as a large symbol in the centre of the screen for a few seconds and then they are displayed in their normal display location whilst the function is activated.



Green is normal condition



OPERATORS MODE Caution Symbols are displayed initially at start up and the system carries out a check , then as long as there is no fault the symbols disappear. If a fault occurs during operation then the symbol is displayed in the centre of the screen and it replaces the centre gauge.



When the maintenance symbol appears the operator should contact his Komatsu dealer.



OPERATORS MODE If the maintenance warning symbol displays or if the status requires checking then the keypad button 6 is pressed and the maintenance function is displayed .



OPERATORS MODE



Hours remaining until maintenance is due



Maintenance interval



If Number displayed is Yellow then the maintenance time is near.(< 30 hours) If the number displayed is red then the time for maintenance is due.



Once selection is made to the specific maintenance item we can reset it by pressing enter and confirming the selection.



OPERATORS MODE When a failure occurs on the machine the User code E02,E03,E05 can be displayed This is followed by the telephone number and the 6 digits failure code



OPERATORS MODE The electrical failure codes can be deleted from the monitor history but the mechanical failure code are on for the life of the machine. See Service mode for further information on the failure codes.



OPERATORS MODE Attachment control When an attachment is installed and the function is enabled on the monitor panel, the flow and pressure going to the attachment can be altered by the operator. When in A and E Mode the flow is adjustable between 30~430 L/min. The safety valve on the service segment is also kept at the high setting in this mode. In Breaker mode the flow can be set to 3 levels and then adjusted within each level giving a flow adjustment between 70~210 L/min. When B mode is selected the flow is adjusted automatically and the pressure is reduced to the lower setting on the service safety valve.



OPERATORS MODE In A and E mode



30~430 L/min Both pumps used High pressure enabled at service segment Use up/down arrows to adjust.



OPERATORS MODE 70~210 L/min One pump Each bar =10L/min Low pressure setting



In Breaker mode



OPERATORS MODE Attachment control Automatic ATT-circuit-switching function was added; the circuit is switched according to an operation mode selected. Lifting boom and operating attachment decrease flow rate of attachment Complex movement • flow rate of 2 pumps • high-pressure safety Select A,E mode valves(Operating with machine simultaneously, decrease oil flow to ATT) Select B mode



Simplex movement (for breaker) • flow rate of 1 pump • low-pressure safety valves

SERVICE MODE To access the service mode Key in the following :Hold in the up arrow and press 1-2-3 in sequence and this will bring up the service menu. It contains 7 selections



SERVICE MODE 1. 2. 3. 4. 5. 6. 7.



Monitoring Abnormality Record Maintenance record Maintenance mode change. Phone number entry Default Adjustment



In the flashing yellow box key in the number selection or use the up/down arrow to move your selection and then press return.



SERVICE MODE 1. Monitoring measurement items Within the monitoring function we can monitor up to four measurement items on the machine However for a fast screen update use only on a single item. Only 2 measurement items can be displayed in conjunction with an On/off display 2



SERVICE MODE 1. Monitoring measurement items



You can hold the data being displayed by pressing this button .



Machine settings can be altered freely without coming out of the monitoring mode



SERVICE MODE 1. Monitoring On/off display items Similar to Dash 6 bit code patterns, we can test the on/off signals to confirm the correct function of solenoids and switches on the machines. A maximum of 2 can be displayed at once. When displaying a measurement item only 1 on/off display can be shown.



SERVICE MODE 2. Abnormality Record (electrical) The machine monitor stores two types of failure information 1. Electrical failures. 2. Mechanical failure. To access the information select, “ 02 Abnormality record” from within the Service mode and you will see the screen displaying the choice of failure codes. A max of 20 codes can be stored then the oldest code is erased. 1/2
