1Risks
1.1 Risk of electromagnetic radiation
When operating the axes of Jenny Science AG,
electromagnetic fields are generated which may be
dangerous for persons with pacemakers or implanted
defibrillators.
Persons with magnetically influenced implants or with
prostheses that contain ferromagnetic components are
at risk due to the magnetic fields that occur and must
therefore under no circumstances carry out work with
this type of equipment. During operation, a safety
distance of at least 1 meter must be observed.
1.2 Risk from magnetic force
Due to the high magnetic field strengths, large attractive
forces occur especially in the immediate vicinity (distance
of approx. 50mm between the magnetic tracks).
Therefore, it must be strictly observed that objects made
of steel or iron (e.g. watches, rings, etc.) as well as
technical devices (e.g. computers, credit cards, hard
disks, etc.), which can be attracted, influenced or
destroyed by the magnetic field, are not led into this area
with the free hand. An appropriate safety distance must
be maintained.
1.3 Risk due to surface temperature
During operation, the surfaces of the motors can become
correspondingly hot. The surface temperature of the
motor can reach up to 80°C.
Monitoring devices and the error messages of the
controllers must be checked continuously. If there are
changes compared to normal operation, switch off the
motor.

2General notes
2.1 ESD protective measures
Built-in components (e.g. temperature sensors,
measuring system) may contain electrostatically sensitive
components (ESD). Observe the ESD protective
measures.
Do not touch electrostatically sensitive components /
connection points!
2.2 Professionals
All transport, connection, commissioning and
maintenance work must be carried out by qualified,
responsible technical personnel.
3Transport and packaging
Upon receipt, check if the system has been damaged
during transport.
When unpacking the system, take care not to damage
sensitive parts such as cables, connectors, encoder and
motor.
The commissioning of damaged products is
prohibited.
4Environment Conditions
Storage and transport
No storage outside. Storage rooms have to be well-
ventilated and dry. Storage temperature from
-25°C bis +55°C
Operating temperature
5°C -50°C environment, after 40°C performance reduction
Operating humidity Cooling
10-90% non-condensing
No external cooling needed.
Dynamics can possibly be increased by mounting the
slider case / flanch on a heat conductive ground plate.
Protection
IP 40 (For higher requirements please contact us)

5Handling with Linearmotor-axis
5.1 Carriage
The linear motor axis should always be transported in a
horizontal orientation, since the carriage of the linear
motor is not self-locking in a vertical orientation.
For linear motors with cover (Lxe) is a risk to bend the
steel cover plate. It is to be careful not to carry the linear
motor on the cover plate.
5.2 Measuring system
Incorrect handling of the linear motor axes with a
magnetic measuring system could erase parts of the
magnetic measuring tape. Prevent magnets, e.g. from
other motors, and measuring tape from colliding.
Incorrect handling of the linear motor axes with optical
measuring system can scratch the glass scale and thus
lead to errors. Keep it clean and do not touch it directly
with your hand. To clean the optical measuring system,
use a lint-free cloth and cleaning spirit.

6
6Mechanical assembly
Use protective gloves and suitable tools for mechanical
assembly.
The carriage of the linear motor axes must never be
removed from the guide. This will cause irreparable
damage.
Additional applications can be mounted using the tapped
holes and fitting holes provided for this purpose (see
data sheet of the corresponding motor).
6.1 Tightening torques
Static friction coefficient μT = Steel,
Aluminium alloy dry
Strength class (Screw) = 70
6.2 Flatness for mounting on ground plate
If the linear motor axes are mounted on a base plate, this
must have a flatness of 0.01mm. Otherwise the linear
motor axis may be distorted when screwed down and
the guides may jam. This increases wear, reduces the
service life and can damage the guides.
6.3 Flatness for mounting on slider
The same requirements apply to the contact surface of
components that are screwed onto the slide of a linear
motor axis. This contact surface must have a flatness of
0.01mm.

6.4 Screwing sequence
In order to avoid distortion of the motor during
mounting to a base plate, it is important to observe the
sequence of screwing. The screws must be tightened
from the inside alternately left and right to the outside
6.5 Flatness practical test
Before mounting the ground plate or the slider, please
test how smooth the slider can be moved by hand. After
tightening the screws, move the slider again by hand.
There should not be any noticeable changes in
smoothness, otherwise the contact surfaces have to be
revised.
7Electrical connection
A defective or incorrect power supply may result in
irreparable damage to the machine.
An earthing cable must be connected to the system at all
times.
Do not pull any plugs during operation!
There is a danger to life or injury and the risk of material
damage.
Never disconnect electrical connections while they are
under voltage. Before disconnecting, switch off the
power supply and disconnect at least and wait at least 10
seconds.
The drives must not be connected to any other power
supply than the one specified.
Connectors with a screw device, must be screwed down
accordingly.
Use only original Jenny Science AG cables and do not
modify them.

8Commissioning and running
During operation, motors can have hot surfaces. The
temperature of the linear motor can reach up to 80°C.
Monitoring equipment and the error messages of the
control devices must be continuously controlled.
Switch off the engine if deviations from normal operation
occur, eg increased temperatures, unusual noises,
increased vibrations, etc...
The slide of the linear motors in vertical alignment are
not self-locking when switching off the power.
8.1 Weight compensation
Improper opening of the weight compensation is
prohibited.
Make sure that during installation and maintenance
work, the pneumatic supply has been turned off and are
not the supply lines under pressure.
Use only clean and oil-free air.
8.2 Spring brake
Improper opening of the spring brake on
LINAX® Lxs/Lxu is prohibited.
Make sure that during installation and maintenance
work, the pneumatic supply has been turned off and are
not the supply lines under pressure.
Use only clean and oil-free air.
The air connections should be kept as short as possible.
The response time of the corresponding valve is to check
with the respective manufacturer.

9
9Service and maintenance
Maintenance work may only be carried out when the
axes are completely stopped. The axes must not be in the
regulation and must first be disconnected from the
power supply.
The linear motor system must not be immersed or sprayed in
liquids for cleaning.
Basically, coarse contamination should be removed with a soft
brush or with oil-free compressed air.
