1 Description of the product

Linear actuators RA 600 consist of a direct current drive (volt-

age see technical characteristics), whose drive energy is trans-

ferred over a worm gear and a spindle lifting gear to the push-

ing rod.

The self-locking spindle lifting gear stops the actuator in case of

power failure and maintains it safely in the reached position.

Features of the sturdy design are the generous dimensioning of

the actuator and the solid design of the housing.

Linear actuators RA600 are protected against corrosion and

function without any troubles also in rough operating and envi-

ronmental conditions.

Since they are maintenance-free, this is permanently guaran-

teed.

Features of the sturdy design are the generous dimensioning of

the actuator and the solid design of the housing.

As an alternative to the code class IP66 also a press and

splash water protection as per code class IP69K is available.

Linear actuators are maintenance free and can be operated

with a duty cycle of up to 15%.

Version with limit switches

The version with limit switches has 2 integrated sensors, which

automatically switch off the motor as soon as the upper or

lower stroke end position is obtained. This guarantees that the

linear actuator does not mechanically push against the stop.

Version with stroke measuring system

The version with stroke measuring system allows the realisa-

tion of control-oriented applications and the operation of sev-

eral linear actuators in synchronism.

The stroke ends are freely definable by means of the digital sig-

nal.

Version with self-locking

All linear actuators are designed with a self-locking mechanism.

For higher safety in the case of a break an internal lock nut can

be provided.

This is possible as special solution on request.

given in this manual, in order to avoid personal damage or ma-

terial damage.

• Read these operating instructions thoroughly and com-

pletely, before you work with the product.

• Keep these operating instructions so that they are accessi-

ble to all users at any time.

• Pay attention to the current safety regulations, regulations

for accident prevention and environmental protection of the

country in which the product will be used.

• Use the ROEMHELD product only in perfect technical con-

dition.

• Observe all notes on the product.

• Use only accessories and spare parts approved by the

manufacturer in order to exclude danger to persons be-

cause of not suited spare parts.

• Respect the intended use.

•You only may start up the product, when it has been found

that the incomplete machine or machine, in which the prod-

uct shall be mounted, corresponds to the country-specific

provisions, safety regulations and standards.

•Perform a risk analysis for the incomplete machine, or the

machine.

Due to the interactions between the product and the ma-

chine/fixture or the environment, risks may arise that only

- Influence of hydraulic and electrical control,

- etc.

6 Application

6.1 Intended use

The electric linear actuator may be used for linear stroke move-

ment only.

It may only be centrically loaded with the maximum forces indi-

cated in the technical characteristics.

The electric linear actuator may be used in applications, where

a loss of the retention force can endanger the safety of the

user, with a safety nut only.

The decision whether the user is endangered must be taken by

the manufacturer of the application.

Every other use is not admissible.

Customer's modifications of the electric linear actuator are not

permitted.

The electric linear actuators must only be used within the envi-

ronmental conditions indicated below the technical characteris-

tics.

Note

Other demands on the use, service life and load have to be

agreed with the manufacturer.

The electric linear actuators have two fork eyes with Ø 12 mm

for the connection of the user's construction.

The connecting construction has to be designed so that no

forced conditions act on the pushing rod.

The electrical connection is made by coded plug-type connect-

ors.

Note

Design and dimensions of the connecting construction see

chapters Mounting and Installation!

The electric linear actuator must be installed protected against

torsion. The pushing rod must be installed without any side

loads.

NOTE

Durability and environment tests.

The product is designed for the use in outdoor applications and

is correspondingly resistant to corrosion.

•Before using this product the user has to check the usability

of the product for its application by own durability and envi-

ronment tests.

6.2 Misapplication

WARNING

Injuries, material damages or malfunctions!

•The product must never be opened. At the product no

changes must be made, except the ones expressly men-

tioned in the operating instructions!

The use of these products is not admitted:

•For domestic use.

•On pallets or machine tool tables in primary shaping and

metal forming machine tools.

•In areas for which special guidelines apply, especially in-

stallations and machines:

- For the use on fun fairs and in amusement parks.

- In food processing or in areas with special hygiene regu-

lations.

- In mines.

- In explosive and aggressive environments (e.g. ATEX).

•For other operating and environmental conditions.

Non-system components or not authorised installations must

not be connected to the electric linear actuators.

Note

The stroke end positions must not be loaded mechanically. An

approach in creep speed or switching off 3 mm before reaching

the end positions is required. For supply units with synchroniza-

tion control this is met by the programmed soft stop function.

The positioning accuracy with touch control amounts to

± 2 mm, depending on the operator and the load.

Place tasks with higher demands on the positioning accuracy

can be realised with special controls.

Therewith place accuracies can be realised within the size

range of the resolution of the stroke measuring system.

CAUTION

Injury by rotating parts!

The product does not have an anti-torsion device. The extend-

ing pushing rod and mounting parts can rotate.

•Operate the product only in installed condition.

Side loads and forced conditions on the product lead to

the premature failure.

•If required, provide external guides.

•Avoid forced conditions (overdetermination) of the product.

•Max. forces and torques see technical characteristics.

Fixing the connecting cable

• The cables must be fixed by the user so that no bending and

tensile stress will act and the cable cannot be damaged in

any way.

Component damage caused by faulty control

Use control of data sheet M 8.200.

If user's control is provided, this control must be equipped with

the following functions:

•switching off in case of over-current as protection against

blockade, collision, etc.

•current limitation as protection against damages,

•switching off in case of short circuits as protection against

overheating and fire, etc. and

•recognition of defect displacement transducer as protection

against damages, etc.

Do not approach the mechanical stops

It has to be guaranteed by the user's control that the element

will not be moved to the internal mechanical end positions.
