Some anomalies also trigger flashing LEDs on each side of the display. Yellow LEDs are for minor faults while red LEDs are for major faults. NOTE : All faults are not treated the same way by the microcontroller. Some have little impact (like fuel low level), some will generate a 50% cut in the drive signal to the drive pumps while some will prevent the vehicle from being set in motion. The operator may dismiss the problem and continue to operate the vehicle. In that case, the warning indications on the screen will re-appear periodically. The operator may solve the problem on site or a mechanic make the repair in a shop. If this is the case, proceed as follows to clear the fault indication on the display: » Turn off the engine and re-start it, or: » Complete the erasing sequence as follows: » Execute a complete brake application cycle (safety belt of the seat must be buckled). » Press the last button to the right (under the down arrow icon) to access the icons shown on the following figure, then press the last button to the left (under the “X” icon). 0274670270 Figure 52 NOTE : The icons will disappear after a few seconds. One of the previous procedures is required to modify the fault status from active to passive. On the Fault log page of the display, the Qty of that fault will be increased by one. Remember that clearing a fault does not eliminate a problem. A problem must be solved by the operator or an authorized technician and then the fault has to be “cleared” as described previously. Once cleared, the fault goes from active to passive and will be recorded in the microcontroller fault log. 44/110 SW50 - Operation and maintenance manual OVERHEAD CONSOLE OVERHEAD CONSOLE 1 FAN SPEED CONTROL KNOB 2 0274600026 13 12 11 The knob is located on the overhead console.
