scopeofdeliveryyoumustalsocarryoutthefollowingadditionalmeasuresforrst-time
commissioning:
1. Mechanical fastening
Fix LUB-V mechanically. Pay particular attention to the maximum tightening torques.
2. Electrical connection
Connect LUB-V with an external power supply system (e.g. PLC) by adding a proper
connecting cable to the electrical interface on the side of LUB-V.
3. Check the assembly
Make sure that LUB-V is assembled properly and completely. In particular, the external
power supply system has to be connected and a lubricant cartridge must have been
tted.
4. Power on
If you want to put LUB-V into operation, switch on LUB-V. LUB-V only delivers lubricant to
the lubrication point according to the settings when switched on. The detailed description
for powering on can be found in chapter 6.3.3.
5. Execute FIL function
Execute the FIL function. The detailed description can be found in chapter 6.3.9. LUB-V
performs a certain number of strokes and transports lubricant from the cartridge to the
outlet.
6. Hydraulic connection
Connect the consumer hydraulically to LUB-V. If you connect tubes to LUB-V make sure
that tubes and connectors are installed tightly, cleanly and correctly.
 Ideally,usetubesprelledwiththeappropriatelubricant.
7. Check the settings on LUB-V
Check the required values for the lubrication point at the factory settings of LUB-V and
adjust them if necessary. Changes at LUB-V can be made in PRO menu, chapter 6.3.7.

19
6. Operation and settings
6.1 General information
What you should know about operating and setting LUB-V:
LUB-V is suitable as a multi-point lubricator for one or two lubrication points. However,
dependingonthespecicapplication,LUB-Vcanalsoreliablyandcleanlysupplyalimited
number of lubrication points with lubricant. Accessories from the manufacturer (e. g.
splitters or progressive distributors) can be connected to LUB-V. If necessary, changes
must be made to LUB-V settings to ensure safe and reliable operation.
LUB-V is a cycle controlled lubricator which works time-based via the integrated micro-
electronics and is connected to a 24 VDC power supply. LUB-V cyclically delivers a
denedquantityoflubricantfromthecartridgetotheoutlet.Twooperationmodescan
be selected.
Hour mode -h- allows setting the number of cycles (c) and a pause time (h) between
two dispensing cycles in hours. Pause times (h) between 1...240 hour(s) and cycles (c)
between 1...10 can be set.
Additionally, LUB-S-V can be embedded into a programmable logic controller (PLC)
which sends orders and controls LUB-S-V in impulse mode (see chapters 6 and 8).
How to switch to operation mode PUL is described in detail in chap. 6.3.8.
A dispensing cycle consists of at least one (1) dispense (stroke) and can consist of a
maximum of ten (10) dispenses. Up to ten (10) dispenses per outlet are made in direct
succession. After the end of the lubrication cycle LUB-V rests until the set pause time h
has elapsed and then automatically carries out the next lubrication cycle.
The disposable interchangeable cartridge with 400 ml lubricant guarantees a controlled
andconstantqualityofthelubricantandislledbubble-free.LUB-Vallowsahighsupply
security of the lubrication point and prevents failures.
LUB-V cannot be used without a lubricant cartridge. Depending on the version ordered
the cartridge can already be included in the scope of delivery and may already be
connected and installed in LUB-V.
The respective conditions of LUB-V can be seen in the LCD. It additionally enables the
optical recognition of the condition by means of coloured LEDs.
If you have any questions about your application and the correct settings for LUB-V
please contact the manufacturer (chapter I.II).

20
6.2 Factory settings
LUB-V is always delivered with the following factory settings:
operating mode: hour mode -h-
mode:  OFF   LUB-Visswitchedo󰀨
The factory settings provide the use of LUB-V in hour mode -h-. If you would like to
operate LUB-V in impulse mode PUL you have to make changes in the SET menu of
LUB-V (chaper 6.3.8).
6.2.1 Default settings, operating mode: hour mode -h-
Pause time h = 3 The pause time is 3 hours.
Number of cycles c = 1 The number of cycles is one (1) stroke
per outlet.
The default settings in hour mode when using a LUB-V with one (1) lubricant outlet
result in an emptying time (service life) of 338 days (= 11 months) for a full 400 ml
lubricant cartridge, provided that LUB-V is permanently switched on and no special
dispenses have been made. Within approx. 3 hours, LUB-V will deliver one dispense per
stroke (0.16 cm³).
If you are using LUB-V with one (1) lubricant outlet, one dispensing stroke will be
delivered from one outlet at the end of the pause time. If you are using LUB-V with two
(2) lubricant outlets, one stroke per outlet will be delivered at the end of the pause time.
The emptying time of the cartridge is halved.
lVerify that the default settings are appropriate for your application and that
the lubrication point is supplied with the correct amount of lubricant per time unit.
If this is the case, you can operate LUB-V with the default settings in hour mode -h-.
If this is not the case change the values for the pause time h and number of cycles c
accordingly; see chapter 6.3.7 for an explanation of how to make these changes.
TouseLUB-Vitmustbeproperlymountedandinstalledrstandthenswitchedon.
The installation is very simple and is described in detail in chapter 5.2; switching on is
described in chapter 6.3.3.
If you order a factory-provided special version of LUB-V, the information contained in
the supplement is authoritative.
