1. Main Screens and Control Buttons

Menu: Used to Enter into Menu List and return to Previous Menu.

Up: Used to move up cursor in the Menu Lists and to increase a Value.

Down: Used to move down cursor in the Menu Lists and to decrease a Value.

The main menu is accessed through the "Menu" button; all the menus are displayed on the right display.

In a given Menu list, you can press the "Up" and "Down" buttons to scroll through menus. Pressing the button will then scroll through menus from top of screen to the last menu on screen; but if the button is pressed, selection will scroll from top to bottom of menus list.

The active line is "inverse video" (white text, black highlighted), use the "Menu" key to get inside the selected submenu.

The last line of a menu list is always defined as "Back", it is used to move to the previous menu by pressing the "Menu" button when highlighted.

Within a given Menu where the value can be changed, the change can be made by using the "Up" button to increase the value and using the "Down" button to decrease the value. Changes are immediately registered in controller. Pressing the "Menu" button returns you to the previous menu.

Start Cycle The three keys "Start Cycle PX" can be used to start a new lubrication cycle at the corresponding pump. Pushing this buttons acts like simulating an Enabling signal coming to the greasing controller, for each pump independently. The chosen pump will start if the Pilot pressure is sufficient.

If pump PX is in safety mode, a three seconds activation of the button the normal mode.

1.2

Sequence of a lubrication cycle

1.2.1 Systems 1 and 2: Upon expiration of the pause time the pump begins operating and supplies the lubricant to the injectors LM5 via the main line.

The pistons in the injectors are actuated by the lubricant under pressure and discharge a pre-dosed quantity of lubricant to the connected lubrication points.

The pressure continues to rise in the main line until the value (220 bar) set at the pressure switches (B69 or B71) is reached.

The control unit stops the pump and, at the same time, the main line is discharged via the solenoid valves (Y79 or Y81). The relieved lubricant reaches the pump reservoir via a bypass.

The pistons in the injectors LM5 return to their initial position by spring force.

The pause time begins. The system is ready to carry out a new lubrication cycle.

Only for the 2 pumps variant: The solenoid valves Y80, Y82 and Y83 allow – after they have been switched accordingly – the systems 1 and 2 to be both supplied together by pump 1 or pump 2 in the case that either pump fails to operate owing to a fault.

1.2.2 System 3 After the pause time has elapsed, the pump supplies the lubricant to the connected progressive metering devices.

A progressive metering device SSV 8 is equipped with a proximity switch for control and monitoring.

A lubrication cycle is completed after the SSV 8 has supplied three times, and the pump is switched off again.

2 Operation CAUTION Only allow operation by properly instructed personnel Do not exceed permissible system pressures Top up lubricant in good time When the machine is started all centralized lubrication systems are automatically pressurized.

Each pump triggers one lubrication cycle, stops only for the preadjusted pause time, ... etc.

Standard: 1 Pump When the excavator is delivered from the factory the time period between two lubrication cycles is six minutes for pump P1 and four minutes for pump P3. This corresponds to a grease consumption of approx. 2000 g/h for P1 and 60 g/h for P3.

Option: 2 Pump variant When the excavator is delivered from the factory the time period between two lubrication cycles is six minutes for pump P1 and P2 and four minutes for pump P3. This corresponds to a grease consumption of approx. 1700 g/h for P1, 300 g/h for P2 and 60 g/h for P3.

The time intervals for P1, (or P2 and P3 respectively) can be readjusted at the lubrication system monitor.

4 Inspection and maintenance * * *

Do not perform any repairs while system is pressurized.

To relieve pressure open a threaded connection carefully Caution: Lubricant may escape while pressurized

Regular inspection and maintenance are the prerequisites for proper operation of the centralized lubrication system over a prolonged period of time. The warranty on our product can only be valid if the prescribed maintenance intervals are adhered to.

The regular inspections and maintenance procedures are described below: 1. System as a whole Daily:

Visual check of the lubrication points for escaping lubricant Visual check of the hose connections for leaks or wearing

Weekly:

Visual check of the screwed pipe connections for leakage Determining the time for one operating cycle. If the time determined differs from the usual operating time, the individual components (pump station, injectors, pipes) must be checked.

Functional check of the pressure switch

2. Pump station Weekly:

Check that threaded connections and hoses are firm and tight.

Visual check of pump tube gland seal Check function of the solenoid valve Check electrical cable connections Clean outside of pump station

1000 hours:

Clean filter element of grease filter

7500 hours:

Hydraulic pump: Change gland seal

3. Injectors Daily:

Check movement of control pins: During the work cycle the pins must be retracted depending on the metering quantity; in the resting phase all the pins must be extended.

Weekly:

Visual check for leaks

4. Progressive Plunger Metering Device Weekly:

Visual check for leaks

5 Topping up grease reservoirs CAUTION

5.1

Lines are pressurized. Be careful when decoupling.

Observe extreme cleanliness when topping up the grease reservoirs.

Contaminated lubricant causes malfunctions and premature wear of the grease pump and other components of the system.

Clean surroundings before topping up Switch off centralized lubrication system (turn off engine)

P1 and P2: Filling of the container

Filling of the container through service-plate Remove dust protective cap at the filling coupling and the dust protective cap at the filling nipple Couple the filling hose at item 10 and switch on the filling pump When the reservoir is full, the ultrasonic sensor transmits an electric signal to the control unit. Visual control is possible through the sight-glass on the 600 L rectangle reservoir the filling pump is switched off Disconnect the filling coupling and reinstall the dust protective caps
