Safety
user groups strongly depend on their role, we distinguish between the following user
groups:
Operating Authority
Executor
Technician
Reseller
Operator
Intermittent
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 actuator. The operating authority ensures that the user is instructed on the authorized use
of the equipment.
The executor is the contractual partner of the reseller or the manufacturer. He assembles the linear actuator into a total device. He is authorized by the manufacturer RUNNER™ to use the linear actuator in accordance with the regulations and has the necessary expert knowledge.
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.
The reseller forwards the machine.
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
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)

Page 12
Structure and Function
Function
A description of its function allows you to understand what the linear actuator and its
individual parts do.
Principles of its function
The principle of the linear actuator RUNNER™ is based on push or pull functions. A push
or pull movement is exerted with a push tube. The built-in brake brakes the movement
or holds the position at a standstill. There must be no side pressure and no torque.
The linear actuatorRUNNER™ has to be equipped with a Magnetic-controller and a Magnetic-operating element.
Core
Motor housing(3)
Motor unit
Gears
Linear unit
Thermo-switch
The core is the load-bearing component that connects the motor unit, the gears and the
linear unit (main bearing) with each other.
The motor housing is a two-piece synthetic housing and must not be opened for any reason. The power supply cable (motor cable with low-voltage plug) is permanently built
into the motor housing. The motor unit and the gears are located inside the motor housing.
The permanent magnet motor is a 24 V DC motor that drives the gears via the toothed
belt. The speed of the stroke depends on the load.
The two-step planetary gear system is driven by the toothed belt, by which a threaded
spindle is moved.
The linear unit is one of the components separate from the motor unit. The threaded
spindle converts the rotational motion of the gears into a linear motion via the spindle
nut. A safety nut provides additional protection, in case of a fracture of the spindle nut,
from a fracture of the push tube. The push or pull movement is carried out by means of
the push tube. The push tube is surrounded and protected by the guide tube 2. The base
of the push tube is connected via the spindle nut to the threaded spindle; on the top piece
is the fork head of the push tube.1
The thermo-switch in the motor controls thermal and electrical overload and switches
off the motor in an emergency. The actuator must not be operated until the actuator
temperature has fallen below the switching threshold.
Brake
Limit switch
The brake is attached to the threaded spindle and serves to brake it.
The actuator is equipped with two internal limit switches, which turn the actuator off at
the limit positions. An additional emergency limit switch de-energizes the linear actuator if one of the limit switches fails. Switching on the RUNNER™ again is then no longer
possible and the actuator has to be returned to the manufacturer. (see Manufacturer
Address, page 6).

Operating elements
It is possible to equip the actuator with an optional emergency lowering mechanism for
patient lifter applications. Then it is possible, e.g. as happens with a power failure or
actuator malfunction, to manually lower the lifter; also see the section Emergency Shut-
down, page 15.
The electric entrapment safeguard is an electrical switch that switches off the linear
actuator when the stroke is hindered by an object or a body part.
With the Hall sensor, the impulse sender picks up impulses from a magnetic disk located
on the threaded spindle.
The Linear potentiometer determines the position through the resistance value (actual
value) and therefore registers the absolute path.
The linear actuator RUNNER™ can be optionally supplied with method of protection
IPX6S. It is then also RUNNER™ protected from water sprays (also see 4. Normal Operation, page 14).
Accessories
The linear actuator RUNNER™ needs a Magnetic control unit to power the motor. Only
use Magnetic controller units.
You can operate the linear actuator RUNNER™ remotely by means of the Magnetic operating element on the control unit. Only use Magnetic operating elements.
Important: Magnetic Elektromotoren AG will not take any liability if the linear actuator RUNNER™ is not used with a suitable Magnetic control unit / operating unit.

Normal Operation
The Magnetic control unit must be connected to the electrical main. Operation takes
place through a Magnetic operating element (also see Accessories, page 13).
Emergency lowering
mechanism
Patient lifter
For patient lifter applications with an emergency lowering system, it is desirable in special cases, such as in a power failure or actuator malfunction, to lower the load by turning by hand.
Note: needing to use excessive force or an independent downward movement indicate a damaged actuator. The RUNNER™ must not be run any more. Immediately
inform the manufacturer that performs the inspection.
Emergency Shutdown
1 Pull out the plug of the cable that connects the linear actuator to the control unit.
Note: The RUNNER™does not have an on / off switch and must be separated from
the power supply to the control unit. Only this measure will de-energize the RUNNER™.
An emergency off switch is absolutely essential for patient lifters.
Note: The emergency shut-off switch must be fitted by the executor.
