2.0 General
2.1 Using the Technical
Instructions
The Technical Instructions are intended for designers or
specialists who use the ECOMAG linear actuator in their
products, and for tters who work with the actuator. The
Technical Instructions contain all relevant information on this
Ewellix product.
We reserve the right to make changes which are in the inter-
est of technical progress.
Please read the Technical Instructions carefully and, above
all, pay careful attention to the Safety Instructions.
The Technical Instructions should be used for drawing up
the User Manual for the end product.
2.2 Correct usage

3.0 Function
ECOMAG linear actuators are DC actuators with worm gears
and spindle units. The gears convert the motor's rotational
movement into a linear movement through the threaded
spindle's rotation being transferred to a pushing tube via a
special nut.
The stroke is limited by built-in limit switches.
The power is supplied via an attachable or externally tted
SEM 1 control unit. The control unit consists of a control box
housing the transformer, the converter, up to 4 motor socket
connections and a socket connection for the control device
(e.g. handswitch).
WAINTING
The maximum load specied on the label must not be exceeded,
since doing so will mean that the prescribed level of safety will
not be provided.
The actuator may be destroyed if it is overloaded!
The linear actuator is operated using a control device (e.g.
an EHE handswitch).
The feed speed is a function of the load!
The ECOMAG can be loaded with push forces (ECO 2/4/6/8)
or pull and push forces (ECO 3/5/7/9).
DANGER
The ECOMAG linear actuator "push version" (ECO 2/4/6/8)
may only be subjected to compressive loads. If pull forces are
applied, the push tube can disengage from the outer tube.
Risk of accident!
The maximum load on the actuator shown on the label refers
to the centric push tube axis.
A mechanical anti-pinching device for pull forces is tted in
the "push" versions. In the "pull-push" versions, a mechani-
cal anti-pinching device is available as an option.
The self locking of the actuator is at least equal to the push-/
pullforce.

4.0 Installation and startup
4.0 Installation and startup
4.1 Scope of delivery
The ECOMAG actuator system comprises the following:
• Control unit
• Actuator and
• Control device
4.2 Installation
The linear actuator must only be installed over the two fork
heads. The load must act centrally on the push tube axis
and, when the actuator is installed, it must be free from any
other mechanical forces.
DANGER
The bolts and brackets for transferring the forces must be
suitable for the purpose intended and be matched to the
dimensions of the fastening ttings.
Risk of accident!
If there is a risk of hitting a mechanical limit stop during a
stroke movement, Ewellix recommends that mechanical an-
ti-pinching protection or a current cuto device be used.
When the rapid adjustment option is used, it must be en-
sured that the entire stroke movement can be completed.
4.2.1 Mounting position
As a general rule, all mounting positions are possible, pro-
vided the following points are noted:
If the control unit is plugged in, only the mounting positions
shown in Fig. 1 from 0° to 90° are permitted.
If an overhang arrangement is used, the control unit must
also be xed in position with cable ties. The control unit can
otherwise work itself loose.

5.0 Operation
5.1 Controlling an actuator
The EHE handswitch is used to actuate one or more
ECOMAG linear actuators. A control panel is provided on
the front foil of each handswitch for each actuator that is to
be controlled (⮑ g. 12). This consists of two push-buttons
that are positioned oset from each other. On the front plate
are the symbols which are assigned to the function and are
used for adjusting the individual linear actuators.
Up to 4 linear actuators can be actuated separately.

DANGER
If the feed speed of the linear actuator diminishes, or it no longer
works under load, it must be uninstalled immediately and taken out
of use.
Risk of personal injury!
Pressing one of the push-buttons activates the relevant lin-
ear actuator. It moves for as long as the button is held
depressed.
• Button The actuator extends
• Button The actuator retracts
5.1.1 Fastening hook
It is possible to retrot the handswitch with a fastening hook.
The fastening hook is attached to the adhesive surface pro-
vided on the rear of the handswitch using adhesive lm.
5.2 Locking device
As an option, it is also possible to lock the individual actua-
tors on the EHE handswitch. This gives the unit failure safety
in accordance with EN 60601-2-38.
In Lock or Unlock programming mode, the locking key must
always be placed in the bores situated on the rear of the
handswitch.
Fig. 13
WARNING

5.0 Operation
5.3 "Emergency lowering"
in the event of a power
failure (option)
If the power fails, the actuators can be moved to their lower
terminal position.
If the "EMERGENCY lowering" features a patient safety
function in the event of a power failure, the user must ensure
that:
• the battery capacity is satisfactory,
• the function is checked regularly by briey pressing the
"AB" ("DOWN") button.
The following batteries, which have been approved by the
manufacturer, may be used:
• Panasonic 9 V Alkaline 6LR61,
• Varta 9 V Alkaline 6LR61 and
• Energizer 9 V Alkaline 6LR61
5.3.1 Changing the batteries
• Remove the cover (⮑Fig. 14).
• Replace the batteries.
• Replace the cover with the line mark facing upwards.
Fig. 14
WARNING
Ewellix, recommends that the batteries be replaced each time the
"EMERGENCY lowering" function is used.
Damaged, spent batteries must be replaced anyway.
WARNING
Batteries must be disposed of correctly or returned to Ewellix. They
must not be disposed of in the general household waste!
WARNING
Protection class IPX4 is only guaranteed if the marking on the cover
matches the marking on the housing.
5.4 Rapid adjustment
(optional)
5.4.1 Function
The rapid adjustment function is used for "emergency rapid
lowering" of the head or the foot of the bed (during patient
resuscitation).
If a power failure or actuator malfunction should occur, or for
beds which are not connected to a power supply, the rapid
adjustment device can be used to manually lower the head
or foot of the bed (further option).
When installing an actuator with rapid adjustment function, a
warning notice (⮑ Fig. 15) in accordance with EN 60601-1,
Section 6.3c and 6.4, must be attached clearly to the end
product (insofar as the end application is subject to this
standard).
Fig. 15
WARNING
The rapid adjustment function should only be used in emergencies,
or to test that it is working properly.
When retracted, the actuator must lie against a fixed limit stop (e.g.
bed frame), since otherwise the actuator may be damaged by a
rapid- lowering action.
No transverse forces (misaligned mounting) must be allowed to
act on the linear actuator, since otherwise the function of the rapid
adjustment feature cannot be guaranteed.
The screws in the pivot clamp must not be tightened or loosened!
WARNING
The rapid adjustment function must be checked every 6 months.

12
Ecomag
5.4.2 Usage
• Open the red clamping lever (⮑Fig. 16, (1)).
While doing so, hold the head of the bed rmly. Depending
on the bed design, the head or foot can lower quickly.
Fig. 16
• Manually press the rapid adjustment mechanism down-
wards (⮑Fig. 17, (3) e.g. backrest).
Fig. 17
• Close the red clamping lever (⮑Fig. 18, (1)) until it
reaches its end position (4).
Fig. 18
You must ensure that, whatever position the clamping lever
is in, it can be actuated as shown in gs. 14 and 15.
After a rapid lowering action, the clamping lever must be in
closed position before the linear actuator is used again.

6.0 Maintenance and Care
6.0 Maintenance and Care
6.1 5.1 Maintenance
The actuators may only be opened and worked on by the
Ewellix Customer Service.
The fork heads, housing and power cable must be checked
for mechanical damage (e.g. cracks) every 6 months.
DANGER
The maximum current consumption under full load must be
measured. It must not exceed the value specified on the label.
Higher current consumption means that the linear actuator is
overloaded and may be damaged!
The user must undertake to monitor the products vigilantly.
The actuators are greased with Ewellix-approved lubricants,
and do not require any maintenance for the following service
life:
Service life: Max. 10 000 double-strokes with a stroke of 200 mm.
(The question of how the double-stroke specication is
translated into a useful service life must be dened by the
manufacturer of the end product).
When the service life expires, the actuator must be removed
and overhauled by the manufacturer. Risk of personal injury!
For applications where it is highly likely that the service life
will be exceeded, we recommend the use of the optional
safety nut.
The rapid adjustment option must be checked every 6
months. If excessive force is needed to move the actuator,
or it runs too freely, it should be exchanged.
6.1.1 Duty cycle
The actuator has been designed for intermittent operation
(see label). If a higher duty cycle is used, please contact the
Ewellix factory.
6.1.2 Thermofuse
The ECOMAG linear actuator is tted with a thermofuse. The
thermoswitch integrated into the motor switches the actua-
tor o if the temperature becomes excessive.
6.2 Care
6.2.1 Protection from water, cleaning,
disinfecting
The following protection classes are only guaranteed in as-
sembled status:
• Linear actuator and control unit IP X4
• Housing of the optional mains
disconnection device IP X0
• Handswitch IP X6 and IP X7
Clean after use in order to avoid the accretion of residues!
The actuator may be cleaned with a damp cloth and water.
