3 OPERATION
When pressurization starts, control unit opens both the line to be pressurized and the pump
solenoid valves. Pressure air starts the pump and opens the line directional valve.
Pressurization continues until the pressure control unit of the line reaches the
acknowledgement pressure level. After acknowledgement the control unit closes the solenoid
valves, the pump stops and pressure discharges from the line to the lubricant barrel.
If the lubricant level in the barrel reaches the low limit level during pumping, the low level switch
sends an alarm to the control unit and pumping is stopped. The alarm can be disabled by
changing the lubricant barrel and resetting the alarm at the control unit.
3.1 Start-up
Caution
Ensure that the pumping center is turned off when the connections are
made.
3.1.1 Maxilube-ECO
Note
Numbers in brackets are part numbers of drawing 461983A.
1. Ensure that the surroundings of the pumping center are clean. Impurities in the system
prevent trouble-free operation and cause damage when reaching the lubrication point.
2. Check the state of the lubricant barrel (1). Damages on the surface prevent the lowering of
the follower plate (2).
3. Remove the lid from the barrel and press the follower plate tightly to the barrel above the
lubricant. Ensure that air is being removed under the follower plate and that the central unit
(3) of the follower plate is filled with lubricant.
4. Place the lid (4) on top of the lubricant barrel. Fasten the lid with wing screws on the
lubricant barrel.
5. Place the pump (5) through the lid into the follower plate central unit. Ensure that the pump
is attached to the follower plate.
6. Fasten the pressure air hoses (6) to the bottom plate connections A1 and A2, the tank
hose for lubricant (7) to the bottom plate connection T and the grease filter (8) to the
bottom plate connection P (Figure 1).
7. Fasten the low level switch (9) to the pump.
8. Connect the low level switch cable (13) and the cables of the channel pressure control
units and shut-off valves to the pumping center as described in the electrical drawings.
9. Connect the hose for pressure air to the pressure air connection (14) of the pump.
10. Ensure that the lubrication device (16) of pressure air regulator (15) is filled with
recommended oil.
11. Adjust the pressure air lubrication in pumping center with lubrication control device (17) of
the pressure air regulator. Min. 1 turn open with VG32 –class oil.
12. Set the pressure of pumping center pressure air to 4 bar (60 psi) (19) with pressure air
control device (18) of the pressure air regulator.
13. Fasten the plug to the tank connection (20) of the pump.
14. Connect the pressure hose (21) to the pressure connection (22) of the pump.
15. Start the pump in manual operation mode of the control unit or with pressure air manual
control screw (23) of the pumping center's solenoid valve group, see chapter
3.3 Manual
operation
. When manual control screws are used, remove the cover plate (11) and the nut
(12) below the plate. After this remove the pumping center cover (10).
16. After the pressure hose is filled, stop the pump and connect the hose to the grease filter.
