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.

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.
