MENU a) INFORMATION ABOUT THE CONTROL OF THE ENGINE RPM (This function is existing since Software Version V2.4). The screen 0/5 appears only on machines on which the engine RPM is adjusted by an hydraulic cylinder via an electronic regulation. The graphic bar in the lower part of the screen gives the momentary value of the regulation current to the RPM control cylinder. b) INFORMATION ABOUT THE HYDRAULIC PUMP : information screens 1/5 (50a - 50b) and 2/5 (51) This screen gives information about the operating position of the hydraulic pumps. The screen 1/5 gives following indications for each working pump if the flow and pressure limitation is activated, and its percentage.
The screen shows for this limitation a graphic bar with electric current value and indicates for the pump the amount of the momentary flow control signal On figure 50a , an external limitation (Hardware entry I1, option 2) ist activated. With this option, the pump flow and operating pressure are limited to 55% of the maximal value. In case of an external activation of limitation, the symbol "R" is displayed in the field TI, see main screen. The figure 50b , two internal limitations (Pressure cut in stage 49 50a boom and translation M1) are simultaneously activated with the external limitation (Hardware entry I1, option1).
With simultaneously activation of several limitations, the one with the smallest value is decisive for the hydraulic pump. In that case, the symbol "R" is displayed in the field TI. In case of only one activation of limitation, the symbol "R" turns into " ". Notice : For R 904 to R924 machines, the signal of regulation solenoid valve EV1 limits both pumps. For R 934 to R974 machines, every pump can independently being limited true regulation solenoid valves EV1 and EV2. For R 984 machines, every pump can independently being limited true regulation solenoid valves EV1, EV2, and EV3.
For every machine, the operating pressure is limited true regulation solenoid valve EV6 50b The internal flow limitation M1 is active during the translation. The internal flow limitation M2 is active by use of pressure cut in stage boom on keyboard . The internal flow limitation M3 is active while the flap is operated. The internal limitation SF, by SF-button switched on. 51 The display 2/5 (51) represents the present current of regulation solenoid valves LR (current value for power regulation). c) INFORMATION CONCERNING THE COOLER FAN CONTROL SYSTEM information screens 3/5 (52) The screen 3/5 appears only on machines fitted with an electronically regulated cooler fan drive.
The graphic bar in the lower part of the screen gives the momentary value of the current to the regulation solenoid valve EV5 for the fan RPM. 52 3.13
