Safety equipment2.5
Integration in an emergency-stop system required
(for certain applications)
The device is only intended for installation into an an application or
system. It does not have its own operating control elements and
does not have an independent emergency-stop-function.
Install the device so that it is part of an emergency shut-off sys-
tem and can be stopped if necessary.
The emergency shut-off system has to be connected in such a
way that a disruption of the power supply or the reactivation of the
power supply after a power disruption cannot cause a hazardous
situation for persons and objects.
The emergency shut-off systems must always be freely
accessible.
Danger of injury caused by moving components
Rotating and/or linearly moving components can cause severe
injury.
Therefore:
Do not work on or place any of your body, hands, or arms near •
moving components.
WARNING
Danger due to malfunctioning safety equipment
For safe operation, be sure all safety equipment is in good work-
ing order.
Therefore:
Always check functionality of safety equipment according to•
the maintenance plan.
Never disengage safety equipment.•
Safety equipment may never be by-passed or modified.•

The following safety installations may have been installed:
Matrix MAX1/Matrix MAX3
In its standard version the device does not feature an overload
safety shut-off and must be turned off via an SKF control unit.
MAX11 and MAX31 are exceptions.
Matrix MAX6
The control unit with integrated power shut-off has been installed in
the motor housing.
Matrix MAX1/Matrix MAX3
In its standard version the device does not feature a thermal fuse
protection and can be destroyed through overheating. An SKF con-
trol unit with integrated thermal switch turns the device off in
emergencies.
Matrix MAX6
A thermal fuse protection has been integrated in the motor
housing.
A ball screw nut converts the rotation of the gear unit into a linear
motion. If an overload occurs when the actuator is operating, a ball
detent clutch will operate, thus stopping linear motion.
Information concerning emergency lowering function, quick adjust-
ment, electrical pinch protection and mechanical pinch protection
can be found in the chapter “Structure and Function”.
Overload safety cut-off
To prevent damage from overheating, do not try to operate
actuator until its temperature has fallen below the threshold for
the switch to operate.

Safeguard against restart2.6
Life-threatening situation through unauthorized restart
For work in hazard zones, there is a risk that the power supply
is turned on without prior authorization. This presents a life-
threatening situation for people in the hazard zone.
Therefore:
Follow the information concerning the safeguarding against•
re-starting of the power supply in the chapters of this operat-
ing manual.
Always follow the process to safeguard against a restart as•
described below.
DANGER
Protect MAX1 and MAX3 against a restart.
Pull the power line plug of the SKF control unit out of the
power outlet.
Protect MAX6 against restart.
Pull the power line plug (connected with connection (1) out of
the power outlet.

Brief description4.2
Fig. 7

5
The actuator is implemented in an application and is exclusively for
the dynamic centric compression- or tensile-loaded lift.
The linear actuator consists of a motor part (1) and a linear unit
(5), connected with each other by a bayonet joint.
The actuator consists of a direct current motor with worm gear
which sets in motion a trapezoidal sliding spindle system with shaft
joint (type B and C) or ball bearing spindle system (type A). Via the
ball screw mount the trapezoidal sliding spindle or ball bearing spin-
dle system transforms the rotation of the gear into a linear motion
of the actuator (3).
The hinge head (2) and the fork head (4) transmit the actuator
power to both sides of the application.

Special features4.3
Matrix MAX1 and MAX3
The device requires an external control unit to power the motor unit.
The control unit is connected to the device via a connecting cable.
The SKF operating control element is also connected to the control
unit, († fig. 8).
The difference between the linear actuators of Matrix MAX1 and
MAX3 consists in the different outputs († Chapter “Technical Data”).
Matrix MAX6
The device does not require an external control unit. The control unit
is integrated in the multi-shell plastic housing. To power the motor
unit, the device is directly connected to the supply voltage via the
power line connection. The SKF operating control element can also
be connected directly to the device († fig. 9).
The Matrix MAX6 linear actuator can be used in a master actuator
function with a second DC actuator (slave actuator) with jack plug
(† Chapter “Options”).
!Note!
Additional differences between the Matrix MAX1, MAX3
and MAX6 linear actuators can be found in the appendix in the
Chapters “Safety Features”, “Connections”, and “Data Sheets”.

description
Motor
The motor is a 24-V-DC, whose motor shaft powers a worm gear.
The lift speed depends on the load. The motor unit is surrounded by
and fused with the multi-shell plastic housing. The plastic housing
cannot be opened. A bracket clasps around the plastic housing.
Brake
The brake is located in the motor unit and takes care of the decel-
eration of the spindle as well as the stabilization in idle mode.
The maximum self-preservation force of the brake in idle mode
can be found in the respective data sheet (†Appendix).
Gear unit
The worm gear is directly powered by the motor shaft, which
depending on the version, moves a trapezoidal sliding spindle or ball
bearing spindle.
Linear unit
The actuator extends and retracts the push tube. The actuator is
surrounded and protected by the casing tube. The footer of the
actuator is connected with the threaded spindle via the ball screw
nut.
The linear unit is connected with the motor unit via a bayonet
joint. The bayonet joint is protected by a plastic cover which also
functions as a locking mechanism and which must not be removed.
