OPERATION 3.4 ELECTRONIC MONITORING AND CONTROL SYSTEM ECS Menu Control with Key Switch (C) and Key Group (D) Setting of Operational Data, menu item Service *SETTINGS* Example: Changing the pause time of the Central Lubrication System 12. After the numerical values have been changed, press key (1) one time (Acknowledgement of new setting). The information on the display changes to the introduction message page -0- or if a message is present to the respective message page. 13. Press ”RET” key (9) five times for return to standard display. Example:
Changing the hydraulic oil viscosity grade When changing the hydraulic oil, the viscosity grade of the new oil has to be entered in the appropriate ”Service/Settings” group, if the viscosity of the new oil is different from that of the drained oil. REMARK The procedure up to the menu item *PTO GEAR-OIL VIS- COSITY* is described on the preceding page Changing pause time of the Central Lubrication System; item 1. to 3. Starting from menu item *PTO GEAR-OIL VISCOSITY* in level -3- proceed as follows, see Menu Control Chart II. 1. Press key (12), the item *HYDRAULIC-OIL VISCOSITY* is displayed. 2.
Press key (10), level -4- Input of viscosity with the information f the present oil viscosity grade appears on the display. 3. Press key (10) once more, the information ”OPERATE KEY SWITCH” appears on the display. 4. Operate key switch (C). 5. ”Input of oil viscosity” appears on the display. Under present: the used oil viscosity grade is indicated. Under new: all the viscosity grades available in the system are offered for selec- tion. The example on Chart II shows changing the viscosity grade from VG 22 to VG 100. 6. Press key (12) until in the field new: VG 100 appears. 7. Press key (10), to acknowledge the new viscosity grade. On the display the information in the field present :
changes to VG 100 . The procedure input of a new hydraulic oil viscosity grade is now finished. For returning to the standard display on level -0- press the key ”RET” (9) four times. REMARK When a battery voltage fault has occurred, the operational data (oil vicosities, timer settings etc.) stored in the Programma- ble Logic Controller (PLC) can be lost and must be re-entered after the correct battery voltage has been re-established. 123
