Description

Matrix linear actuators have been de-

signed in particular for seating and

reclining operations (hospital beds). The

drive is provided by a DC motor with

worm gear which acts on a trapezoidal

threaded spindle drive system (type B and

C) or ball screw system (type A). The

actuators are protected against over-

heating by the SKF control units. When

used in stand-alone operation, built-in or

external current cut-off Printed Circuit

Boards (PCBs) need to be used. Matrix

actuators employ push/pull technology.

The self-locking function is ensured by

means of the built-in brake. Furthermore,

all actuators are protected against

overload by means of a safety nut and a

static safety factor of 4. The actuators

comply with EN 60601-1 (1990), EN

60601-2-38 (1996) (only with PUR-

mains cable) and UL 2601. All forces are

transmitted via metal parts. High-quality

die-cast metal parts, stainless steel push

tubes and ultrasonic welded plastic parts

guarantee high performance and

compliance with degree of protection

IP66S. Stroke and mounting lengths can

be selected in increments of 50 mm over

the range of 50 to 400 mm and in

increments of 100 mm over the range of

400 to 700 mm. Special strokes and

mounting lengths on request.

Electrical connection

The motor is connected via the Magnetic

control unit. The plug must be fitted into

the relevant slot in the control unit. The

actuators are controlled by means of the

appropriate control elements. When the

actuators are operated without a control

unit, it is essential that built-in or external

cut-off PCBs are used. The actuators are

not fitted with limit switches. Cut-off is

therefore by means of the control unit or

current cut-off PCBs. Overload and/or

damages can therefore be ruled out if

used as recommended. In industrial

applications with the need of high lifetime,

external limit switches must be provided.

The push force is reduced by 50 % when

operated in parallel with the SKF control

units (exception: control units with

enhanced power).

Installation

The actuator is secured to the fork heads

by means of bolts. It is important here to

ensure that the load which is to be moved

acts centrally onto the push tube. No

lateral forces may act on the push tube

whatever the orientation, and the actuator

must not be installed off-centre. The

technical instructions must be observed

for installation and putting into service.

Any applications which do not comply with

these technical instructions must be

discussed first with the manufacturer.

Applications which involve a risk of

personal injury must be made safe by the

user.

Maintenance

The Matrix requires no maintenance

during its lifetime. The expectable lifetime

depends on the particular model and the

application. The user must conduct his

own tests in this regard. Faulty actuators

may only be opened and repaired at our

factory.

Accessories

Additional datasheets are available for

other accessories, actuators, control units

and control elements.

Description



reclining operations (hospital beds).

MAX6 actuators are connected directly to

the mains and can be used as either

stand-alone units or in master/slave

configurations with a second DC actuator

(Matrix or Telemag). They are controlled

directly by means of a control element.

The simple plug & play system cuts the

user’s installation time and saves the

space otherwise required for a separate

control unit. The switched power supply

integrated into the housing powers a DC

motor with worm gear which acts on a

trapezoidal threaded spindle drive system

(type B and C) or ball screw system (type

A). The control unit with integrated current

cut-off is integrated into the motor

housing. Matrix actuators employ push/

pull technology. The self-locking function

is ensured by means of the built-in brake.

Furthermore, all actuators are protected

by means of a safety nut. The actuators

The electrical connection is made by

means of the mains cable. The actuator

is available for mains voltages of

230 V/50 Hz and 120 V/60 Hz. MAX6

actuators can be controlled using either a

pneumatic hand switch or foot switch (not

powered) or a low-voltage control

element. Hand switches and foot switches

are plugged directly into the motor

housing. The master/slave configuration

requires a two-channel low-voltage

control element. Direct control is also

possible via a 4-wire mains connecting

cable. The customer must ensure that

wiring and cut-off functions comply with

requirements.

Quick release

Especially for use in hospital beds, a

mechanical quick release for the rapid

lowering of the bed back and foot sections

is available for type C actuators. With quick

release on push (motor direction pull), the

safety factor is reduced to 1.5. In actuator

variants C, this release also boasts an

integrated mechanical anti-pinching

protection. Type A and type B actuators

are available with mechanical anti-

pinching protection only. The retracted

length is correspondingly longer and can

be procured from the selection tables. The

lowering speed following release can be

regulated by the adjustment screws. Quick

releases are available in two variants.

Please consult the manufacturer if these

variants are to be used with accessories.

Linear actuatorsMATRIX Accessories

Electric anti-pinching protection

The actuators can be equipped with an

electric anti-pinching protection (safety

cut-off) for retraction movements. A

special rear fork head with an oblong hole

and an integrated cut-off pin ensures

actuator shutdown via a micro-switch. In

the event of pinching, the pin lifts off the

attachment bolt and causes the shutdown.

Actuators with motor direction pull are

installed inverted and have special internal

wiring.

Bearing insert for fork head

Plastic inserts for the fork heads are

supplied as standard. When using these

components, the dimensions of the

attachments must be adjusted according

to dimensional drawing. See data sheets

Connection diagram ZDV

ZDV current cut-off PCB

When the DC actuators are operated

without KOM control units, a separate

current cut-off PCB is required. This cut-

off PCB can be supplied built into the

drive, externally or in a special ZDV

housing. The use of this PCB protects the

actuator against overload. The current

values on the cut-off PCB are pre-set at

the potentiometer. Connection and wiring

is according to a special scheme. The

integrated fuse is 10 A inert.

Encoder

The DC actuators can be supplied with

integrated mechanical 1-channel

encoders. The encoder has 8 pulses/

revolution at the spindle, current 10-100

mA, voltage 24 V. Signalling is via the 3-

pole standard cable with jack plug. This

actuator version can be operated with the

processor control or with special customer

control units.

External limit switch ZSC

An external limit switch connection for

monitoring particular functions can be

added in connection with either a KOM

control unit or an SPP locking device

Pull relief ZBE

EN 60601-1 stipulates that net cables

must be protected with an additional pull

relief. These pull relief clamps are available

with and without anti-torsion device. They

can be supplied for special customized

wiring.
