General Hazards on Non-Compliance with the Safety Instructions
The subsystem has been designed in accordance with state-of-the-art technical
developments and is operationally reliable. If it is not operated by qualified or at
least trained personnel or if it is operated improperly or not in accordance with the
operating instructions, however, the unit may bear the risk of hazards.
Electronic, moving and rotating components can
Danger for life and limb of the operator or third persons and / or
cause material damage
If the linear actuator is installed in a machine plant, the safety requirements noted
in the operating instructions for that machine must be combined with those
described in this manual.
1.4.2. Intended use
The linear actuator has a number of uses including:
Positioning, transporting, feeding, removing, pallet handling, loading, unloading,
processing and manipulating as well as testing work pieces or tools.
Since the component can be used in a very wide range of applications, the user is
responsible for its use in specific applications.
Please make sure that the mounting of parts or tools will not pose a threat to
persons or cause damages to any parts or devices. This also applies, for example,
to the case of a broken toothed belt (if existing).
The linear actuator must only be used in areas that are not accessible to persons
during operation.
If the linear actuator is used in areas accessible to people, it must be installed in
such a manner that no one can be endangered during operation.
1.4.3. Identifying Residual Dangers and Hazardous Areas
If there are still residual dangers present to persons or property from the linear
actuator in spite of operating it in a safe manner, the user must make reference to
these residual dangers through signs and written rules requiring appropriate
procedures.
The following safety signal words are used:
Danger! Indicates that an imminent hazardous situation may lead to death or serious bodily harm if
not prevented using appropriate safety measures.
Warning! Indicates a potentially hazardous situation which, if not avoided using appropriate safety
measures, could result in serious or minor injury.
Caution! Indicates a potentially hazardous situation which, if not avoided using appropriate safety

1.5.1. Special notes on transport
Special notes on transport
Use only transport equipment with sufficient lifting capacity. When using ropes,
make certain they are not twisted or knotted. If you are using more than one rope,
all the ropes should be equally taut.
When transporting the ETH with a forklift, establish a condition of equilibrium and
secure the load if necessary.
Never step under overhead loads - danger of being injured!
Moving parts must always be secured against slipping or moving.
*By wrapping several turns of strong adhesive tape around the sliding carriage, which if possible is in
the centre of the profile, for example.
Note
Danger when transporting long actuators. Because the actuator bends under its own
weight, guiding accuracy may deteriorate significantly. In addition, the shape of the profile
may change and the travel behavior of the (sliding) carriage may be negatively affected.
Additional information on transport: (see on page 8)
In general no means of transport are needed for the LCB. The linear actuator can
be carried, depending on the size, by one or two persons.

1.6 Warranty conditions
User Conversions and Changes are Not Permitted
The linear actuator must not be changed in its design or in terms of safety without
our approval. Any change as defined here made by the user excludes any liability
on our part.
1.7 Conditions of utilization
General introductory notes
With this linear actuator you bought a product which was manufactured and tested
before delivery with the utmost care.
Please take your time to read the following notes which you ought to follow closely
during setup and operation.
The operation of the linear actuator is only permitted within the range of the limit
values stated in this manual.
Unless, all claims under the warranty will become void and a reduced service life
or even damages must be expected.
Please compare the operating data with the stated limit values especially
with reference to:
Stroke length and setting of the limit switches, those must be set so that there is a
sufficient safety travel at both ends of the travel stroke
Even if the limit switches were already mounted at our premises, they must be
adapted according to suitable values before operation!
Speed
Acceleration
Environmental conditions (e.g. temperature, contamination)
Please do take possible pulses caused by moved masses into consideration for
the operating data.
Note on the installation of the linear actuator
Do always use all available mounting possibilities and respect the requirements
listed in chapter "Preparations for substructure (see on page 11)",
"Fitting/mounting (see on page 12)".
If the motor used with the linear actuator should be able to exceed individual limit
values, the respective values for the motor must be limited in the control by
appropriate parameterization. The parameterization should even be reduced down
to the values necessary for operation.
The externally mounted end stops of the linear module may under no
circumstances be accessed during operation. The end stops are only intended for
safety purposes.
The lifetime of the linear actuator depends strongly on the degree of power
exploitation and on impermissible operating states occurring - even if only for a
short time.

2.2.3. Setting the end limits
The software end limits (programmable end limits) can be used to define the
maximum travel path in the positive and negative direction. The machine zero
initiator (home switch) must always be within the software end limits. The switch
must be mounted so that the sliding carriage can under no circumstances travel
beyond (the switch should ideally be mounted in proximity of the drive station or the
deflection station. Switching distance 2 - 4 mm) if needs be an additional external
buffer must be fitted.
Caution The software end limits are not preset. For this reason, they must be defined and entered
into the control system before the unit is placed in service.
Note Recommendation: The actual zero point of your controller should be the same as the
machine zero point.
2.2.4. Attachment of Motor or Gearbox
If you ordered the LCB together with a coupling kit, the coupling housing with the
half-coupling is already mounted on the drive shaft of the linear actuator. In this
case please proceed with step 2, if not start with step 1.
(1) If the coupling housing and the half-coupling are not pre-assembled,
please proceed as follows:
Place half-coupling for small shaft diameter on the drive shaft (with distance AL to
LCB) and tighten clamping screw with torque MA.
Insert plastic part.
Mount coupling housing
(2) Coupling housing and half coupling are pre-assembled:
Place the other half-coupling on the gear- or motor shaft and fix with distance AK
to the flange surface of the drive unit with torque MA.
Fix gearbox and motor to the coupling housing (the gearbox shaft must be exactly
centered with respect to the drive shaft of the linear actuator!
There should be only an air gap of about 0.5 - 1 mm between the half-coupling on
the gearbox- or motor shaft and the other half-coupling.

3.1 Safety Instruction
Before performing any maintenance or repair work, turn the power switch to the '0'
setting and secure it with a padlock against manipulation. If the unit needs to be
operable for specific repair works, you have to be especially cautious. Ensure by all
means that no persons are in the hazardous area. If required, safeguard the
hazardous area with additional barriers or gratings against unauthorized persons.
Repair jobs must only be performed by qualified specialists or employees of
Parker.
Only qualified expert personnel is permitted to perform works on the linear
actuator. All the applicable regulations and provisions must be heeded (IEC, EN,
national accident prevention regulations etc.).
Qualified persons as the term is used in this manual are persons who:
Persons who, by virtue to their training, experience and instruction, and their
knowledge of pertinent norms, specifications, accident prevention regulations and
operational relationships, have been authorized by the person responsible for the
safety of the system to perform the required task and are capable of recognizing
potential hazards and avoiding them (definition of technical personnel according
to VDE015 or IEC364),
Persons who have a knowledge of first-aid techniques and the local emergency
rescue services.
Persons who have read and will observe the safety instructions.
If set-up, repair or maintenance works require that safety installations be
dismounted, these must be r
einstalled immediately after the respective works
have been completed. The unit must be shut down before any of the safety
installations are dismounted.

3.2 Maintenance schedule
Note Please take special care during all maintenance and repair that the guiding surface
remains intact!
WHEN WHAT ACTION
After commissioning Sliding carriage
Check free movement of the sliding carriage by manually
moving the sliding carriage.
(Check)
(see on page 17)
every 4 weeks or every 1000 km* Sliding carriage
Check sliding carriage play and replace sliding blocks if
necessary. (Exchange wearing parts) (see on page 17)
Check free movement of the sliding carriage by manually
moving the sliding carriage.
(Check)
(see on page 17)
semi-annually or every 5000 km Toothed belt Visual inspection of the toothed belt for wear. Change toothed belt if necessary. (Check toothed belt) (see on
page 20)
*With the first set of sliding blocks (new LCB) please check the sliding carriage play
weekly or every two weeks, as an increased wear can be expected during the initial
break-in phase.
3.3 Check free movement of the sliding carriage
Move the sliding carriage manually over the entire stroke distance after assembly
or setup. The sliding carriage must move easily and with constant force. If the
sliding carriage does not move easily or rather "joltily", please check the following:
Make a visual inspection of the guiding. Check for visual wear and for
smoothness of the guiding surface. If necessary, replace profile. If the force
needed to move the sliding carriage changes continually (increases or decreases
continually), an alignment error of the double-axis actuator could be the case.
New alignment of double axis (see on page 13).
Possibly too high deflection of the guiding profile. If needs be, reduce distance
between supports (see on page 11).
If the causes mentioned above do not apply, please check the sliding carriage
play (check sliding play) (see on page 18).
3.4 Replacement interval for wearing parts
Check sliding carriage / play of sliding carriage
The diagrams "Bearing capacity of sliding carriage / wear" show the wear of the
sliding blocks in an ideal case of load on the sliding carriage. The wear can differ
from the indicated curves in a specific application.
Depending on the load and the distance traveled, the sliding blocks in the sliding
carriage wear down and the sliding carriage play will increase accordingly. If the
increased sliding carriage play does not have a negative influence on the
application, the sliding blocks can be operated up to the wear limit (0.5 mm wear
for LCB040 and 1.0 mm wear for LCB060).
The wear limit given in the diagrams may under no circumstances be exceeded -
this could damage the surface of the guiding irreversibly!

Unscrew only the two upper screws of the cover at the deflection station (unscrew
for about 1 3mm, not more as they do not only fix the cover but also the deflection
station itself).
Remove cover in upwards direction
Unscrew the two fixing screws at all four sliding blocks entirely and remove sliding
blocks.
Mount new sliding blocks in reverse order. Tighten screws only slightly. Move
sliding carriage forwards and backwards several times (so that the sliding blocks
are aligned) and then tighten screws.
