3 Description of the lubricator
The lubricator is designed as a highly compact double piston pump for grease as lubricant.
The two pistons run with forced-control and in opposed directions. They are both connected to
the same outlet. The outlet is secured by an integrated check valve. At each dispensing process,
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 volume dispensed per time to be adjusted or set to ensure ideal supply of lubricant
to the lubrication point.
The different operating modes are displayed at the front as well as other additional information
(e.g. empty cartridge, errors).
Power supply is established via interface M12x1. This interface can also be used to relay
information on an empty cartridge as well as error messages, e.g. to an external control system.

to space restrictions or reasons regarding accessibility, lines 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 bundle. For protection against humidity and dirt, these are
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 intended 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. However,
the lubricator can also be used for reliable grease supply to several lubrication points
depending on the actual application case. This can be achieved by connecting parts of
the system accessories (e.g. splitters) to the lubricator. In such a case, it may be necessary to
change the settings at the lubricator to ensure safe and reliable operation.

Tbl - 11 Number of cycles c, strokes per cycle
The emptying 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 (1 stroke = 0.15 cm3).
The time between two lubrication processes (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.

6.4 Error messages
The status is permanently monitored by the microelectronics integrated in the lubricator.
In case of any irregularities, an addressed error message is issued and shown on the display.
The red LED flashes every 5 seconds to visually indicate an error.
Display
Error
Explanation
Correction
E1
Cartridge empty
•Place a new cartridge on the
lubricator (see chapter 8.1.3
"Cartridge change").
iNo need to acknowledge the error; it
is automatically cleared after the
corrective action is performed.
E2
Cartridge error;
cartridge not
recognized or
incorrectly fitted
E3
Undervoltage
•Check the power supply of the
lubricator
•Switch the lubricator off (OFF) and
on again (On).
E4/E5
Fatal error
The error E4/E5 can have different
causes:
- Increased voltage for a short time,
28...30 V, and too short motor
runtime.
- The connected supply voltage was
too low and therefore the motor
runtime too long.
•In these cases, the error is
corrected by switching the lubricator
off and on again.
Important! Between switching the
lubricator off and on, 60 seconds must
be waited.
•If the error E4 / E5 still persists,
remove the lubricator from the
application and return it with the
lubricant cartridge and a description
of the error to WITTENSTEIN alpha
GmbH for inspection.
E7
Overload; the
counterpressure
at the lubrication
point is too high
•Check the lubrication point and
eliminate the cause.
•Switch the lubricator off (OFF) and
on again (On).
Tbl - 13 Malfunctions
iIf the lubricator is connected to an external control system (PLC), for example, when an error
occurs, the differentiated error messages are sent to the PLC for errors E1 ... E7 as output
signals via PIN 4 of the electrical interface of the lubricator (see chapter 7.2 "Factory setting
E1 – L1 – F0").
