safety instructions and the rules and regulations applicable at the place of use. Generally
applicable legal regulations and other rules as well as the relevant rules and regulations
for accident prevention (e.g. personal protective equipment (PPE)) and environmental
protection must be observed.
2.1 EC/EU Directive
Within the scope of the EC/EU Directive, (re)commissioning of a machine on which
LUB-D has been installed and/or tted is prohibited until it has been clearly estab-
lished that the machine complies with the provisions of the applicable directive.
An EC/EU declaration of conformity for LUB-D can be found in the appendix (chapter
11.2).
2.2 Hazards
In order to avoid danger to the user or damage to the machine on which LUB-D is used,
LUB-D may only be used for its intended purpose (chapter 2.5) and in a technically safe
condition.
Always inform yourself about the general safety instructions (chapter 2.7) before starting
to work.
2.3 Sta󰀨
Onlyqualiedsta󰀨whohasreadandunderstoodthismanualmayworkwithLUB-D.
Local and/or company regulations apply accordingly.
2.4 Reasonably predictable misuse
Any use of LUB-D which exceeds the maximum permissible technical data is generally
considered to be improper and therefore prohibited.

08

1.2 General safety instructions
The following safety instructions are given for LUB-D:
DANGER
Damagedorawedelectricalconnectionsorunlicensedhot
components lead to heavy injuries or even death.
• All work on electrical connections shall be provided by
qualiedpersonnelonly.
• Immediately change damaged cables or plugs.
NOTICE
Loose or overloaded screw connections can cause damage to
LUB-D.

torques specied for this purpose. Use a calibrated torque
wrench.
WARNING
Lubricantsareammable.
• Incaseofredonotuseawaterjettoextinguish.

Fig. 1: Overview LUB-D
LUB-D is designed as an extremely compact double piston pump. The two pistons run
force-controlled and counter-rotating. LUB-D is available with one, two, three or four
lubricant outlets (see chapter 5). The outlets are secured by an integrated non-return
valve. Approx. 0.16 cm³ of lubricant is pumped during each dispensing operation.
The present Lubricus D needs to be embedded into an external control (PLC). It provides
an electrical interface which is used to control and command LUB-D.
Furthermore, output signals of LUB-D enable a remote control which shows possible
error messages (e.g. empty cartridge) and allows to query the status anytime. By means
of various input signals processed by the microelectronics LUB-D is controlled to supply
the lubrication point with the ideal amount of lubricant.

11
3.2 Nameplate and designation
The nameplate of LUB-D is visibly attached to the side of the pump itself. There the
CE mark and the serial number of LUB-D are visible. Refer to chapter 3, Fig. 1 for the
location of the nameplate and serial number.

4. Transport and storage
4.1 Packaging
LUB-D is delivered in an outer packaging (cardboard box) and - depending on the scope
of delivery - with a lubricant cartridge and other accessories in the same package. To
protectthemfrommoistureanddirttheyarealsopackedinPElms.
Dispose the packaging materials at designated disposal points in compliance with the
relevant national and company regulations.
After receiving LUB-D check the delivery note for completeness and correctness. Any
missing parts or damages must be reported immediately to the forwarding agent, the
insurance company or Gruetzner GmbH in writing.
4.2 Transport
NOTICE
Hard shocks due to e.g. falling or setting down too hard can
damage LUB-D.
• Do not throw LUB-D.
• When using lifting equipment only use hoists and load hand-
lingattachmentsinperfectconditionandwithsu󰀩cientload
capacity.
• The permissible lifting weight of the lifting device must not be
exceeded.
Store LUB-D in its original packaging in a vertical position in a dry, frost-free environment
at an ambient temperature of +5 °C to +30 °C. The maximum storage time in unopened
condition is 2 years.
Theso-called"rst-in-rst-out"principle(fo)isrecommendedforstoragelogistics.

LUB-D is designed as a compact central lubrication unit for supplying one or more lubri-
cationpoints.DependingonthespecicapplicationLUB-Dcanalsoreliablyandcleanly
supply a limited number of lubrication points with lubricant. In this case accessories (e.g.
splitters, progressive distributors or lubrication gears) can be connected to LUB-D in
order to extend the number of lubrication points beyond the number of outlets. LUB-D
is available as a version with one and as a version with two pump bodies. The outlets of
pump body (PB) 1 are marked on the housing with 1.1 and 1.2, the outlets of pump body
2 with 2.1 and 2.2.

6. Mounting
6.1 Preparations
Before starting to work, inform yourself in detail about LUB-D using this user manual; and
follow the general safety instructions (section 2.7) in particular. Prepare the installation
site carefully.
NOTICE
Pressurised air can damage the seals of LUB-D and can trans-
port dirt and foreign matter into LUB-D or the lubricant.
• Do not use pressurised air.
• Make sure that there is no coarse dirt in the mounting area.
Remove housing from power unit
lSeparate the housing from the power unit
by turning the retaining ring counterclockwise.
Make sure that no dirt, water or foreign
bodies enter the lubricant inlet.
6.2 Assembly
Condition as delivered
LUB-D is delivered in a cardboard box.
Depending on the version ordered further
accessories such as battery, lubricant
cartridge or brackets are included. It also
contains a short manual for experienced
users to start up and assemble the unit for
thersttime.
