If the change in the position of the fuel shaft is smaller than the preset value, no extra lubrication is made. The reference is an adjustable parameter and can be adjusted in accordance with the set values for the concerned lubricator/vessel.
If the change in the position is larger than the preset value, the lubrication is increased by the control box which switches on the power to the magnet valve, thus changing the air pressure of the actuator. The air pressure inside the actuator turns an eccentrical axel inside the lubricator, which increases the stroke length of all piston pumps inside the lubricator.

The drawings no. 805154 and/or no. 805155 in the LCD appendix in the manual must be scrutinised carefully before dismounting. At remounting it must be ensured that the shaft (pos. 6 on drawing no. 805154 and/or no. 805155) is placed in the same position as before it was dismounted. Do not try to dismount the piston (pos. 6 on drawing no. 805154 and/or no. 805155), as special tools are required to remount it.

MEP regulation is a way to save lube oil while maintaining a safe operational condition during part load. On all engines with timed lubrication an excess of lube oil is used in part load areas. This occurs due to fact that the engine has a RPM dependent injection and the lube oil consumption if specified as a function: g/BHPh of the engine’s load.
If you operate in part load areas, the MEP regulation may help to adjust the lube oil consumption to the actual need.
However, LCD regulation is an automatic joint quantity adjustment increasing the lube oil injection in case of changes in the manoeuvring or loads. This means that the cylinder liner is protected by adding a higher feedrate in short periods when it is needed.
Yes, MEP and LCD regulations can be used together with great advantage. They serve in their own way to achieve an optimum cylinder lubrication of the engine.
The LCD actuator of the lubricator functions based on signals which it receives from a governor or from a control box connected to the fuel regulation shaft. At delivery, the signal is set according to the engine designer’s guidelines.
However, some engines operate under conditions which are different from the average used as basis for the calculation of these guidelines. Therefore, there is also the possibility that you may adjust the settings of the system yourself. We recommend that you consult the relevant material for the control which is used on your engine. In this way, you may perform an adjustment which meets your need for when an increased lubrication is needed.
