2. Lubricants

2.1 General information

All products from SKF Lubrication

Systems Germany GmbH may be used

only for their intended purpose and in

accordance with the information in the

product's assembly instructions.

Intended use is the use of the products for the

purpose of providing centralized lubrication/

lubrication of bearings and friction points

using lubricants within the physical usage li-

mits which can be found in the documentation

for the devices, e.g., assembly instructions/

operating instructions and the product de-

scriptions, e.g., technical drawings and cata-

logs.

Hazardous materials of any kind, especially

the materials classified as hazardous by CLP

Regulation EC 1272/2008 may only be used

to fill SKF centralized lubrication systems and

components and deliv-ered and/or distributed

with the same after consulting with and recei-

ving written approval from SKF.

No products manufactured by SKF Lubrication

Systems Germany GmbH are approved for

use in conjunction with gases, liquefied gases,

pressurized gases in solution, vapors, or such

fluids whose vapor pressure exceeds normal

atmospheric pressure (1013 mbar) by more

than 0.5 bar at their maximum permissible

temperature.

Other media which are neither lubricant nor

hazardous substance may only be fed after

consultation with and written approval from

SKF Lubrication Systems Germany GmbH .


considers lubricants to be a component of the

system design which must be factored into the

selection of components and the design of

centralized lubrication systems. The lubricating

properties of the lubricants are critically im-

portant in these considerations.

2.2 Selection of lubricants

Observe the instructions from the

machine manufacturer regarding the

lubricants that are to be used.

Warning!

The amount of lubricant required at

a lubrication point is speciied by the

bearing or machine manufacturer. It

must be ensured that the required

quantity of lubricant is provided to the

lubrication point. The lubrication point

may otherwise not receive adequate

lubrication, which can lead to damage

and failure of the bearing.

The selection of a lubricant suitable for

the lubrication task is made by the machine/

system manufacturer and/or the operator of

the machine/system in cooperation with the

lubricant supplier.

The bearings/friction points that require lubri-

cation, their expected load during operation,

and the expected ambient conditions are taken

into account during selection, with consider-

ation of economic and environmental aspects.


2.4 Lubricants and the environment

Lubricants can contaminate soil and

bodies of water. Lubricants must be

properly used and disposed of. Observe

the local regulations and laws regarding

the disposal of lubricants.

It is important to note that lubricants are envi-

ronmentally hazardous, flammable substances

which require special precautionary measures

during transport, storage, and processing.

Consult the safety data sheet from the lubri-

cant manufacturer for information regarding

transport, storage, processing, and environ-

mental hazards of the lubricant that will be

used.

The safety data sheet for a lubricant can be

requested from the lubricant manufacturer.

SKF Lubrication Systems Germany

GmbH supports customers

in the selection of suitable components

for feeding the selected lubricant and in

the planning and design of a centralized

lubrication system.

Please contact SKF Lubrication Systems

Germany GmbH if you have further questions

regarding lubricants. Lubricants can be tested

in the company's laboratory for their suitability

for pumping in centralized lubrication systems

(e.g., "bleeding").

You can request an overview of the lubricant

tests offered by SKF Lubrication Systems

Germany GmbH from the company's Service

department.

2.3 Approved lubricants

Only lubricants approved for the prod-

uct may be used. Unsuitable lubricants

can lead to failure of the product and to

property damage.

Different lubricants cannot be mixed, as

mixing may result in damage and ne-

cessitate costly and complicated clean-

ing of the product/lubrication system.

It is recommended that an indication of

the lubricant in use be attached to the

lubricant reservoir in order to prevent

accidental mixing of lubricants.

The product described here can be operated

using lubricants that meet the specifications in

the technical data. Depending on the product

design, these lubricants may be oils, fluid

greases, or greases.

Oils and base oils may be mineral, synthetic,

and/or rapidly biodegradable. Consistency

agents and additives may be added depending

on the operating conditions.

Note that in rare cases, there may be lubri-

cants whose properties are within permissible

limit values but whose other characteristics

render them unsuitable for use in centralized

lubrication systems. For example, synthetic lu-

bricants may be incompatible with elastomers.

2.5 Lubricant hazards

Centralized lubrication systems must

always be free of leaks. Leaking lu-

bricant is hazardous due to the risk of

slipping and injury. Be mindful of any

lubricant leaking out during assembly,

operation, maintenance, and repair of

centralized lubrication systems. Leaks

must be sealed off without delay.

Lubricant leaking from centralized lubrication

systems is a serious hazard. Leaking lubricant

can create risks that may result in physical

harm to persons or damage to other material

assets.

Follow the safety instructions on the

lubricant's safety data sheet.

Lubricants are a hazardous substance. The

safety instructions on the lubricant's safety

data sheet must be strictly followed. The safety

data sheet for a lubricant can be requested

from the lubricant manufacturer.

4.3.4 Connection of motor circuit breaker

(230VAC/400 VAC 3-phase)

The motor circuit breaker is integrated

in the LC502 control cubicle only in the

230 VAC and 400 VAC 3-phase types.

Consult the rating plate or technical docu-

mentation of the motor to be connected for

the electrical characteristics of the motor,

such as rated current.

Determine the maximum permissible

rated current of the pump unit to be

connected

Set the rated current value according to

the rated current specified for the pump

motor on the dial of the thumb wheel

On the thumb wheel (1) on the motor cir

cuit breaker (2), set the maximum permis-

sible rated current value (from the pump

motor).

Check the functioning of the motor circuit

breaker using the test button (4)

4.1 Information on assembly

The assembly procedure for the LC502 control

cubicle is described in detail in the assembly

instructions associated with these operating

instructions.

4. Assembly 5. Design and function


The LC502 control cubicle is designed as a

compact module for simple assembly and con-

tains the LC502 control unit as well as all

components essential for a control cubicle, such

as the basic power switch, motor circuit break-

er (230/400 VAC types), start button, and fault

indicator light.

The display itted to the front can be used to

enter customer-speciic system settings in a

simple and easy-to-follow way. The control

cabinet meets the requirements of the IP54

safety class if the cable glands are assembled/

closed as described in the assembly

instructions.

The LC502 control cubicle and its components

is designed for the control of either dual-line,

progressive, or single-line centralized lubrica-

tion systems, depending on the coniguration.
