2. Safety
This chapter is intended for all users of the linear actuator RUNNER™. It contains
information on its safe use and optimal utilization.
Safety Program
The safety program for Magnetic Elektromotoren AG spells out who is entitled to use it
and the responsibility of the individual user.
The RUNNER™ was designed and build in accordance with the latest technical standards
and accepted safety rules.
EU-conformity is documented with the technical documentation.
Purpose of the RUNNER™
The linear actuator RUNNER™ was designed and built for implementation in accordance
with its authorized use. If you use the RUNNER™ for any use other than that cited, the
manufacturer cannot be held responsible for damage resulting from this.
Authorized Use
The authorized use of the RUNNER™ is the:
■dynamic central push-loaded or pull-loaded stroke
Note: For the operations data, please see the Annex of this operating manual (see
Operations data, page 27).
Unauthorized Use
Every use other than the authorized use without the written agreement of the manufac-
turer or operation beyond the technical limits is considered unauthorized.
You can find the technical operating limits in the appendix (Technical data, page 27) of
this manual and on the model label of the RUNNER™.
Note: in unauthorized use of the RUNNER™, personal injury and property damage
can occur. Keep to the instructions of this manual under all circumstances.
User groups
To ensure safety, we place requirements on the users of the RUNNER™, that must be
adhered to under all circumstances. Only persons who meet the requirements are enti-
tled to use the RUNNER™.
We refer to all persons who operate, use, commission the linear actuator, process it fur-
ther or pass it on for further processing as user groups. As the requirements of these

8
L5311,2540D.0/2.07
Safety
user groups strongly depend on their role, we distinguish between the following user
groups:
Operating Authority
The operating authority is the contractual partner of the executor or the reseller. They
can impose legal conditions on the operating authority when purchasing the linear actu-
ator. The operating authority ensures that the user is instructed on the authorized use
of the equipment.
Executor
The executor is the contractual partner of the reseller or the manufacturer. He assem-
bles the linear actuator into a total device. He is authorized by the manufacturer RUN-
NER™ to use the linear actuator in accordance with the regulations and has the neces-
sary expert knowledge.
Technician
The technician has the professional technical training to implement the linear actuator
RUNNER™ according to its authorized use. Besides the chapter Safety, he is also familiar
with the chapter Special operating modes. He finds the necessary technical characteristic
data in the Annex.
Reseller
The reseller forwards the machine.
Operator
Every other person who uses the RUNNER™ we define as an operator. The operator
must have read the Safety chapter in this manual before using the machine. Moreover,
he must be instructed about the normal operation by the operating authority.
Types of Operation
Intermittent
The linear actuator RUNNER™ is exclusively intended for intermittent operation (see
Technical data, page 27).
Danger Zones
We differentiate between two danger zones that must be observed, depending on user
role.
Persons
The danger zone covering "persons" includes, aside from the actual user, third persons
as well (other personnel, visitors, patients etc.) In case of injury, the operating authority
is responsible.
Device
The danger zone device comes under the user group Executor and Technician and covers
the linear actuatorRUNNER™ and all the mounted-on elements.
Areas of Responsibility
Different areas of responsibility arise, corresponding to the different user groups.
Operating Authority
The operating authority bears the responsibility for the danger zone covering persons
and ensures that only authorized and trained users work with the RUNNER™. He or she
is responsible for the following:
■Identifying the persons who are allowed to use the RUNNER™ (authorized per-
sons)
■Training the user groups
■Holding to all relevant legal conditions and regulations

WARNING
Warning of hand injury from being caught in the fork head of the
push tube when the motor is running. There will be a rotating mo-
tion as long as the fork head is not installed in a device. Do not let
any object or person come into contact with the fork head of the
push tube when the motor is running. Hold the RUNNER™ only by
the guide tube.
WARNING
Warning of danger of crushing and damage to the RUNNER™ owing
to static and dynamic overloading of the linear actuator. When
driving against fixed objects the impact of the force can cause per-
sonal injury. Make sure that there are no persons or fixed objects
present in the danger zone during the stroke..
• Note the maximum permissible operating data in the Annex
(see Operations data, page 27)
• Note the type plate of the linear actuator
WARNING
Warning of side-acting forces. Side forces destroy the actuator and
pose a danger to people. During the stroke, do not manipulate any
of the elements that are connected to the RUNNER™.
CAUTION
Take care about damage to the RUNNER™ from water sprays. The
linear actuator RUNNER™ is splashproofed according to IPX4S, op-
tionally hoseproofed according to IPX6S. These protection types are
not guaranteed during the inward and outward movement. Prevent
the RUNNER™ from being subjected to water sprays or hosing dur-
ing the stroke.
