5.5 Start‑up
Mount the LUB-S carefully according to the steps described in the chapters before. Depending on
the scope of delivery, you must also carry out the following additional measures for the rst-time
commissioning:
1. Check the assembly
Make sure that the LUB-S is properly and completely assembled. In partricular, the battery must be
inserted and a lubricant cartridge must be tted.
2. Power on
If you want to put the LUB-S into operation, switch on the LUB-S. Only if you switch the LUB-S on,
it delivers lubricant to the lubrication point according to the settings. The detailed description for
powering on can be found in chapter 6.3.1.
3. Setting the cartridge size
The LUB-S is factory-set to use cartridges with a 125 cm3capacity. If you use a cartridge with a 125
cm3capacity during operation, you can skip this step. If you use a cartridge with a capacity of 250
cm3 , you must adjust this in the software of the LUB-S in the Settings menu, see Chapter 6.3.4.
4. Hydraulic connection
Connect the consumer hydraulically to the LUB-S. If you connect tubes to the LUB-S, make sure,
that the tubes and connectors are istalled tightly, cleanly and correctly.
LIdeally, use tubes prelled with the appropiate lubricant!
5. Activate lling function
Execute the lling function. The detailes description can be found in chapter 6.3.5. The LUB-S
carries out a pump cycle PZ with a total of 40 lubrication strokes C with the activation.
6. Check the settings on the LUB‑S
Compare the basic settings of the LUB-S with the values required for the lubrication point and ad-
just them if necessary. Changes to the LUB-S must be made in the Settings menu, see Chap. 6.3.4.
