3 Description of the lubricator
The lubricator is designed as a highly compact double piston pump for grease as lubricant. The
two pistons run force-controlled and in opposing directions. They are both connected to the same
outlet. The outlet is secured by an integrated check valve. At each dispensing cycle , approx.
0.15 cm³ of lubricant are dispensed. Multiple subsequent dispensing processes can be set.
The lubricator features an electrical interface. The included magnetic pen allows for the
lubrication amount dispensed per time to be adjusted or set to ensure ideal supply of lubricant to
the lubrication point.
The different operating states are displayed at the front as well as other additional information
(e.g. empty cartridge, errors).
The power supply is established via a replaceable battery. The lubricator can be switched on/off
via the M12x1 interface. An external power supply can also be used to transmit information about
an empty cartridge as well as error messages, e.g. to an external control system.
We recommend the battery-powered lubricator exclusively for stand-alone lubrication points
which do not have to be monitored externally or which may not be supplied with external power.
Owing to its increased operational reliability and the expanded settings options for emitting
signals, the 24V-DC version is the better choice in terms of technology and economic efficiency, if
information about an empty cartridge and error messages are to be transmitted to a control
system (e.g. PLC). You can obtain further information about an existing product from
WITTENSTEIN alpha GmbH directly.

to space restrictions or reasons regarding accessibility, cords can be used between the lubricator
and the lubrication point (e.g. distribution).
The maximum hose length depends on the temperature as well as the used grease, hoses and
accessories.
4 Transport and storage
The lubricator is delivered in an outer packaging (cardboard box) and with a lubricant cartridge
and other accessories in the same shipment. For protection against humidity and dirt, it is
additionally packaged in PE foil. To prevent leakage of the prefilled lubricant from the lubricator,
protective caps are installed at the lubricant inlet and outlet.
Dispose of the packaging materials at the recycling sites designated for this purpose in
compliance with applicable national and operational regulations.
After receipt of the lubricator, check the completeness of the delivery against the delivery note.
Immediately notify the carrier, the insurance company, or WITTENSTEIN alpha GmbH in writing
of any potentially missing parts or damage.

6.1 Operation and settings
6.1.1 General
What you should know about operation and setting of the lubricator:
- The lubricator is designed as an individual lubricator for one lubrication point.
- The lubricator is time-controlled and works time-based via the integrated microelectronics.
Power is supplied from a battery. The lubricator cyclically delivers a defined amount of
lubricant from the cartridge to the outlet.
- The re-lubrication amount is defined in months by the emptying time setting of the cartridge.
Discharge times tof 1...24 month(s) and a number of cycles cof 1…10 can be set.
- The single-use changeable cartridges with a lubricant capacity of 125 cm3ensure controlled
and consistent quality of lubricants and are filled without any trapped air. The lubricator offers
a reliable supply to lubrication points and prevents downtime of machinery. This version of the
lubricator is designed for grease lubricants.
- The lubricator can be used without an external 24 V DC power supply. The lubricant cartridge
is included in the scope of delivery and already installed in the lubricator.
- To call up the empty cartridge message or error messages, an external 24V-DC power supply
is required.
- The respective conditions of the lubricator are shown on the display, which also enables
recognition of the status by LEDs in different colors.

The discharge time tsets the period over which the total volume of lubricant per cartridge is
delivered. Accordingly, this also determines how much lubricant is supplied per month.
The number of cycles cindicates how many strokes are performed per lubrication process and
how much lubricant is supplied per lubrication process.
The time between two lubrication process (pause time) can be determined with the following
formula:
TPause = t x 720 h x c / H
Using tin hours and Has the number of total strokes per cartridge (830, for cartridge 125 cm³)
and a lubrication volume of 0.60 cm³ (c4) over 6 months, the following pause time is obtained as
an example:
TPause = 6 x 720 h x 4 / 830 = 20.9 h
For above parameters tand c, the lubrication cycle is 21 hours. A lubrication volume of 0.60 cm³
is dispensed every 21 hours over a period of six months.
