Fig. 7
The actuator is implemented in an application and is exclusively
forthe 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 spindle 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.

4.3 Special features
Fig. 8
Fig. 9
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”.

4.4 Construction group
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 housingcannot be opened. A bracket clasps around the plastic housing.
Brake
The brake is located in the motor unit and takes care of the deceleration 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.
4.5 Requirements for third party
control units (mandatory in
medical application)
Control units not approved by SKF for MAX1 and MAX3 actuators,
are treated as third party control units.
!
Note!
It is strongly recommended to use original SKF controls
for operation of the MAX1 and MAX3 actuators. If third party
control are Used, there must be good documented evidence
that the requirements listed below are complied with.
The secondary circuit of third party control units must be designed
as an over voltage category 1 circuit. The third party control unit
must be fitted with an overload safety cut-off. The maximum power
input to the device should be only 0,5 A above the nominal value.
The maximum shut-off value may be only 1 A above the nominal
value.
For example: The maximum power consumption is 12 A. The
recommended shut-off value is 12,5 A, the maximum cut-off value
is 13 A.
28
Page 29
The third party control must enable the drive to draw currents up to
25 A for 200 ms after switching on (start-up current). The access
power shut-off feature can also be temporarily de-activated for this
purpose.
The operating voltage of the MAX1 and MAX3 actuators is
24–30 V DC. The no-load voltage of 36 V DC must not be exceeded.
After the system has been installed , ensure electro-magnetic
compatibility. The operating time and duty cycle of the MAX
actuators may not be exceeded.
Push-to-run operation (recommended): The actuator operates as
long as the switch is pressed. If the device does not have signals to
indicate operation, and depending on the application, it is recommended to ha an operational signal installed in the third party control unit.
4.6 Connections
!
Note!
The current cut-off has to be set differently if the main
load direction is in pull mode. Consult the technical data or
datasheet in this manual, for maximum power consumption
values for each type
!
Note!
The third party power supply must have an isolation
between the primary and secondary circuits according to
2 MOPP, and provide a non-grounded secondary circuit

Fig. 15
The electrical pinch protection consists of a hinge head with an elongated hole (1), an integrated control pin (2) and a micro switch,
which turns off the device when it moves against the effective direction. In the event of a jam, the pin is lifted from the fastening bold
and triggers the activation of the turn-off function.
!
Note!
It is recommended that this option is not used in
connection with an impulse transmitter. Additional information
in conjunction with the quick adjustment feature († Chapter
“Operation”).

M A X1 and MAX3
The life span display monitors the time of operation of the linear
actuator. As soon as the calculated total run time has been reached
for the direct current motor (in relation to the life span of the linear
actuator), a visual or acoustic signal will be triggered depending on
the respective version.
4.8.5 Mechanical pinch protection
The mechanical pinch protection uncouples the ball screw nut from
the ball screw spindle in the event of a jam against the effective
direction of the linear actuator.
If a linear actuator is utilized as a pressure engine (extending
application) in the application, the mechanical pinch protection only
works during the retraction of the device.

8.2.1 Cleaning
To be performed by operator
C l ean line actuator:
1 Separate the device from the energy supply.
2 Clean dirty parts with a damp cloth.
Cleaning of emergency lowering device, quick adjustment
device:
1 Separate the device from the energy supply.
2 Clean emergency lowering mechanism or quick adjustment
device with a damp cloth and prophyl alcohol.
8.2.2 Inspections and readings
• Execution by professional electrician.
• The inspections and readings must be performed as stipulated by
the applicable standards and regulations. The list of the applicable
standards can be found in the appendix.
• The inspections must be documented († “Service Log”).
The external metal parts are not reliably connected with the projective conductor, with the exception of the external protective conductor connection. The separation/insulation takes place either through
a double or reinforced insulation or through an intermediate circuit
that is connected with a protective conductor within the housing.
A reading of the protective conductor resistance is therefore not
possible. Potential connections only take place by accident due to
metal parts that touch each other more or less forcefully.
Damage due to incorrect cleaning
Therefore:
• Do not use any aggressive cleaning agents. Water used for
cleaning including the chemical additives must be pH-neutral.
• Liquids must not touch the actuator during the retraction or
extension.
• Only use the auxiliary materials listed by the manufacturer.
• Emergency lowering mechanism for quick adjustment system
may not be treated with oil, grease or other lubricants.
• No steam jets or pressure washers may be used for cleaning.
• Other cleaning agents or cleaning devices may only be utilized
with the manufacturer’s approval.
