8.9.3 Setting the lubrication time of electric grease pump
The electronic controller built in the electric grease pump can realize related control over the
time or cycle of the central lubrication system. When the time programming control is applied,
the cab's central lubrication system indicator fl ashes after the excavator is powered on; the yel-
low LED indicator of the electronic controller will be illuminated for 25 seconds, indicating that the
system is ready for lubrication.
By pressing the start button on the motor's shell or instrument panel, the lubrication cycle begins.
Upon completion of the lubrication cycle, the motor of lubricating pump stops and the shutdown
cycle begins. Subsequent lubrication will start according to the predetermine time schedule. If the
engine is shut off during shutdown period or lubrication cycle, the cycle will be terminated and the
time period will be recorded. When the engine is started again, the lubrication cycle will continue
counting the time from when the previous cycle is terminated. For the suspended lubrication cy-
cle, pressing the forcible start button allows you to activate the lubricant pump. Once the control
unit is energized, a lubrication cycle will be activated. The following illustration shows the panel of
electronic controller of the grease pump.
