2 Overview 2.1 Application The LCG3 curve sensor control unit is used for wheel flange lubrication in rail vehicles with a compressed air supply (SKF lubrication systems EasyRail Compact, EasyRail Low Pressure, EasyRail High Pressure). 2.1.1 SKF EasyRail Compact The oil+air technology is the most widespread solution on the market.
2.2 Operating mode The curve sensor control unit can control the lubrication of the wheels on each side of the rail vehicle using three operating modes. 2.2.1 Operating mode A The wheels on both sides of the rail vehicle are lubricated at the same time.
2.3 Designs The LCG3 is available in two operating voltage designs. The exterior difference between these two designs is to be found in the housing structure and its dimensions. There are versions with a built-in display or with a portable display. The functions of the units are identical. Table 1 LCG3 - Type identification mode LGC3 - X 0 0 - X 0 0...
3 Function 3.1 Operating modes NOTE With time-dependent control, the wheels on both sides of the rail vehicle are lubricated evenly, NOTE regardless of whether the rail vehicle is traveling in a In the following, we describe EasyRail mode B, which straight line or on a curve.

7 First start-up You can also do a test drive with the factory settings so 7.1 Commissioning you can check the settings, especially those of the curve sensor. The correct setting depends on the route profile When commissioning, first fill the lubricant reservoir and and the question of how fast the vehicle moves through the lubricant lines.
7.3.2 Selecting the SubMode 7.3 Setting parameters 1. Select the operating mode and confirm your selection 7.3.1 Modifying settings by pressing the “checkmark” icon. The set value will then be displayed again. To modify the parameters, proceed as follows: 2. Confirm it by pressing the “checkmark” icon. The next 1.

Fig. 18 7.4 Changing the control unit password NOTE The master password supplied with the curve sensor control unit cannot be changed. Only the specific control unit password can be changed. The control unit password that was set at the factory and the master password can be found in section 4.
Fig. 20 7.5 Undo/redo Undo reverses the last changes. Redo restores the last changes. If no settings have been changed since the curve sensor was delivered, undo/redo are not possible. NOTE Undo/redo will also change the device password. Make sure you know both the previous and current device password.
Fig. 21 7.6 Factory settings This restores the factory settings, meaning the settings that applied when the curve sensor was delivered. NOTE These Resetting to the factory settings also means resetting the device password. Make sure that you know either device password set at the factory or the master password.
