1 Description of the product

Linear actuators RA 60 K consist of a direct current drive (volt-

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

ferred over a planetary gear and a spindle lifting gear to the

pushing rod.

The generated lifting force is available as push and pull force.

Linear actuators without stroke measuring systems are

equipped with internal limit switches. These avoid unintended

overrun and overload of the mechanical stop positions.

The end positions of linear actuators with stroke measuring

system are definable by the signal of the stroke measuring sys-

tem.

The sturdy design with code class IP69K guarantees a trouble-

free function also in rough operating conditions.

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 absolute stroke measuring system is equipped

with a linear potentiometer. A slider at the pushing rod pro-

duces a signal at the potentiometer, that is proportional to the

position of the pushing rod. This signal can easily be evaluated

by a priority control and is permanently available. Referencing

is not required. Due to the direct connection of the absolute

stroke measuring system to the pushing rod, one gets a precise

stroke information with slight backlash. This linear actuator is

equipped with a potentiometer and a subsequent amplifier that

generates a standardised output signal independent of the

stroke length. With the stroke measuring system, control-ori-

ented applications and the compound of several linear actua-

tors in synchronism can be realised.

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

can be determined and minimized by the user, e.g. :

Note

The version with (absolute) stroke measuring system is

equipped with a linear potentiometer.

This is evaluated according to the potentiometer principle (volt-

age divider).

For this purpose port d is connected to the reference potential

(0 V) and port e to the constant reference voltage.

At port c only a voltage can be tapped that is proportional to the

position of the pushing rod.

Thus, in retracted mode of the pushing rod a voltage can be

measured near the reference potential and in extended mode

near the reference voltage.

Generally the voltage at port c is connected to an analogous in-

put of the priority control, where it is evaluated.

The input resistance of the analogous input must be >1M ohm

to avoid any influences on the linearity of the absolute stroke

measuring system.

7.3 Mounting - installation

WARNING

Injury / burning due to contact with energized parts!

•Before working on electric equipment, the energized parts

must be de-energized and secured.

•Do not open protection covers at electric parts.

•All electrical works must only be realised by electricians.

Injury by crushing!

Components of the product make a movement while they are in

operation.

•This can cause injuries.

•Keep parts of the body and items out of the working area!

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.

1.Disconnect user's control from the voltage network.

2.Prepare the user's construction to mount the product. Pay

attention to sufficient freedom of motion.

3.Connect the product with the fork head at the front ant at

the rear by means of the user's fixing bolts to the user's

construction.

4.Secure the fixing bolts with convenient components of the

user.
