2.2.2 Functional description
In order to understand the general functional principle of the RACO electrical cylinder, a description of
the complete process when operating the RACO electrical cylinder is given below.
Drawings RACO electrical cylinder “Co pact series”
picture 1: compact series typ 6 in size 2 staight design A
picture 2: compact series typ 6 in size 2 angle design C
picture 3: compact series typ 6 in size 4 angle design C
picture 4: compact series typ 6 in size 6 angle design C
The RACO electrical cylinder is used for the moving and positioning of a mass in the linear direction.
When power is fed to the motor, the rotary movement of the motor is converted into linear movement
of the push/pull tube by means of the spindle/nut system.
The linear movement of the push/pull tube must be stopped by the system controls:
–In the end positions.
End-switches can be integrated in the cylinder or fitted to the moving parts of the main machine.
These signal to the system controls that the end position has been reached. The axial movement must
always be stopped by the controls before the mechanical end-stops in the cylinder are reached.
–In intermediate positions.
The electrical cylinder can also be stopped at defined intermediate positions by additional switches in
the cylinder or on the main machine.
Revision: 03 2.2-5/1 154-45 -8

- In case of overload.
For switching off in case of an overload, the motor must be thermally protected. RACO electric motors
are fitted with a thermo-contact or a posistor temperature sensor, which signals any excessive motor
temperature to the system controls.
Note!
Further information on the electric motor can be found in the operating in-
structions of the RACO electric motor or the installed motor.
2.2.2.1 Safety instructions
The safety instructions in these operating instructions are intended to protect personnel and
equipment against danger and damage which may arise from the improper use, incorrect operation,
inadequate maintenance or other improper handling of RACO electrical cylinders.
The following safety instructions refer principally to the installation and commissioning of the RACO
electrical cylinder.
In order to avoid physical injury or equipment damage, work such as transport, installation, commis-
sioning and repairs may only be carried out by qualified staff (e.g. qualified electricians) who are famil-
iar with electrical equipment.
Note!
Opening the RACO electrical cylinder will invalidate the guarantee, and
can also lead to damage. In case of problems or damage, the RACO elec-
trical cylinder must be opened and repaired only by the manufacturer.
Considerable thrust and compression forces can occur at the thrust tube of the electrical cylinder. Haz-
ards caused directly or indirectly by possible shearing or crushing spots must be avoided by sufficient
clearance distances to stationary equipment near the thrust tube, the actuating element and the driven
element. During operation, this equipment and its components have dangerous, live, moving or rotat-
ing parts. When the electrical cylinder is completely opened, hazards can particularly be caused by ro-
tating shaft ends. Any feather keys inserted must be removed or suitable measures must be taken to
prevent them coming loose.
Before the device is set up, installed and put into operation, the technical instructions (or the part re-
lated to the work to be done) must be read and heeded. This also applies to configuration, program-
ming, modification of conditions of use and modes of operation as well as for servicing. The technical
instructions must be available near the device whenever work is being carried out.
Danger through electric current or voltage!
The drive unit, device attachments, control units and converters contain
components susceptible to electrical discharge that can become damaged
through improper treatment. Above all, fingers must never be allowed to
touch connector contacts.
Even when the motor is not rotating, control and power connections on the motor, device attachments,
control units and converters can still be live and hazardous.
Revision: 03 2.2-6/1 154-45 -8

The equipment must always be disconnected from the power supply before electrical connections are
loosened. Light arcs that damage people and contacts can be produced in unfavourable cases. After
the supply voltages have been switched off and plug-type connectors loosened, wait at least two
minutes before touching live equipment parts or connections: e.g. the connection terminals of the inter-
mediate circuits on converters can be live for up to two minutes after disconnection.
Perceptible changes compared with normal operation in terms of increased temperatures, vibrations,
noise and so on are an indication that function is impaired. To avoid problems that can lead directly or
indirectly to personal and property damage, the servicing staff responsible must be informed.
If in doubt, switch the RACO electrical cylinders off immediately.
2.2.2.2 Safety sy bols on the RACO electrical cylinder
The following safety symbols are applied to the RACO electrical cylinder.
Danger!
During operation, the drive unit can have hot surfaces in accordance with
its protective rating. The surface temperature can reach 100°C. For safety
reasons, the temperature should be measured before touching; wait until
the temperature has fallen to 40°C.
Explosive areas!
If the RACO electrical cylinder is provided with an explosion symbol, this
means that it may also be used in an area subject to the risk of explosion.
You should also note the separate, special connection conditions. Further
information on this is provided in the operating instructions of the motor
contained in the appendix to these operating instructions.
If special dangers are created due to the installation of the RACO electrical cylinder, the system
manufacturer is responsible for indicating these by means of pictograms, and adding them to the
operating instructions.
If the safety symbol on the RACO electrical cylinder is covered or becomes illegible due to dirt or
weather effects, clean the safety symbol or apply a new one.
2.2.2.3 Transport
Inspect the delivery immediately on receipt for possible transport damage. Any damage must be
reported immediately to the transport company.
Lifting equipment should be attached only to suitable points of RACO electrical cylinders such as the
fork head, central pivot, eyes etc.
Use only suitable transport equipment of adequate size and capacity.
Danger of da age!
Secure the RACO electrical cylinder during transport and lifting against impacts to
the push/pull tube and the terminal boxes. Such impacts can lead to damage or
even destruction of the cylinder.
Revision: 03 2.2- /1 154-45 -8

Crash of the product due to insufficient load handling device!
Severe injuries up to death.
Only use tested and appropriate load handling devices.
Load handling device only to be carefully connected on the main chassis
or on the intended spots.
Transport:
2.2.2.4 Storage
If the RACO electrical cylinder is not to be installed immediately, it must be stored horizontally, in a dry
area, and protected from impacts and the effects of weather. Bare metal areas must be protected with
grease or oil, and the push/pull tube must be retracted.
If being stored for more than 2 years, it is recommended that the lubricants are replaced completely.
The RACO electrical cylinder should only be installed immediately prior to commissioning.
Before commissioning, you must first carry out a running check, measuring the idling current or the
nominal current under load. Note these values, and notify us of them if necessary.
The storage temperature should be within the range –10 °C to +40 °C.

Severe injuries up to death.
Secure product against crash.
Do not linger in hazard area below product.
Installation sequence
In order to ensure the long working life and smooth operation of the RACO electrical cylinder, care
must be taken to follow the installation instructions exactly. The installation sequence is very import-
ant, and must be followed.
Checklist of installation sequence:
1. Installation of the RACO electrical cylinder.
2. Installation of the electrical connections for the motor, thermo-contact and end-position switches.
3. Alignment of the RACO electrical cylinder and tightening of all attachment screws.
4. Setting the end-position switches.
2.2.3.1 Mechanical Installation
The electrical cylinder’s thrust tube has been designed to absorb and transfer compression and thrust
forces in axial direction up to the specified maximum force. During mechanical installation of the elec-
trical cylinder, care must be taken that it is installed absolutely flush to the structure. Lateral forces and torques
are not permitted.
Danger of crushing!
Danger of crushing when installing the RACO electrical cylinder. Ensure proper stability
and adequate installation room. Support the weight of the electrical cylinder with suit-
able lifting equipment.
Revision: 03 2.2-9/1 154-45 -8

For torque-free installation, the electrical cylinder must be fixed at the respective attachment points in
the given set-up (swivel joint yokes, joints, pivots or flange). Fittings and base must be dimensioned
for the high forces expected during operation and be sufficiently protected against becoming loose.
During installation, make sure the cylinder is installed absolutely flush to the attachment structure. The
movement curve over the whole stroke in both axes at right angles to the thrust tube must be con -
sidered and aligned carefully. RACO supplies respective bearing bases, cardanic rings or joints to
keep the clearances.
The moving parts that are connected to the actuator on the thrust tube (either directly or via an
actuator) must have ball bearings or be guided. Attachment parts such as rod ends, pivots etc. must
be lubricated before installation.
If the device is fitted with a non self-locking spindle system (e.g. ball screw drive), you must make sure
that the loads are cushioned when working on the device.
The RACO electrical cylinder must work in true alignment. To achieve this, carry out the following
steps:
–Insert the electrical cylinder with its pivot into the bearing (eye or trunnion) provided. Tighten the
attachment screws on the swivel foot bracket Z/SLB 0101 or Z/SLB 0102.
–Use the rod end on the actuator to connect the thrust tube and secure it using the bolt.
–The actuator must have enough clearance at the side and must never collide inside the rod end
when the cylinder is completely extended or retracted.
–If the thrust tube can only be connected with the actuator after the RACO electrical cylinder has
been extended, this step is only carried out after the electrical installation of motor and limit
switch.
Note!
Note the position of the lubricating nipples and terminal boxes (if fitted) when installing
the RACO electrical cylinder, so that they are always easily accessible for maintenance
of the machine or system.
2.2.3.2 Electrical Installation
Connect to the power supply according to the specifications on the type plate.
Danger caused by electricity or voltage!
Severe injuries up to death.
Before working on the electric installation interrupt electric power supply and secure it
against resetting.
The electrical connection may only be executed by a specialist. The terminal box
may only be opened in case it is assured there is no voltage.
Danger through electric current or voltage!
Electrical installation may only be carried out by qualified staff. The terminal box may
only be opened if it is guaranteed not to be live.
Revision: 03 2.2-10/1 154-45 -8

The connection must be carried out as a safe electrical connection, a safe grounding conductor must
be connected. During connection work, always follow the safety instructions and any other relevant
documents provided.
Note!
The RACO electrical cylinder may only be installed and connected if the frequency
and voltage specifications on the type plate correspond to those of the mains network
and the RACO electrical cylinder is not damaged in any way.
The stoppers on the terminal boxes are only for safety during transport. During commissioning on site
they must be replaced by suitable threaded connections and fasteners. When setting the equipment
up in damp locations or outdoors, make sure the suitable protective rating is available. Use suitable
cable screw connections, check terminal box seals.
In the case of three-phase motors, the cylinder extends when the phases L1/L2/L3 are connected to
U/V/W on the terminal board (direction of rotation of the motor for extending movement). Please check
the direction of movement in inching mode. RACO special motors have been designed for use with a
frequency converter. Cooling air must be able to flow freely around the motor.
The bi-metal trigger in the reversing contactor combination must be set according to the specifications
on the type plate. This is the only way to ensure that the electrical cylinder triggers in time and protects
the motor winding without installing additional excess load protection (e.g. EPS06 with rpm monitoring
feature).
If a different motor variant is used in place of the RACO 3-phase motor, see the respective separate
technical description.
Connection and adjustment of the different device attachments (limit switch on the RACO motor, prox-
imity switch, potentiometer, angle of rotation sensor converter / type DMU, path sensors / type: EPS,
angular momentum sensors / type: DIG) must be carried out according to the respective instructions.
Attention!
The device must not be put into operation without stop position limitation (limit switch)
being connected. If there is no stop position limitation included in the scope of supply,
the function has to be carried out on site through external limit switches.
For fail proof operation, make sure wiring is in line with EMC requirements (shielding, twisting, cables
routed separately from potentially interfering cables).
Da age hazard!
Mechanical stop positions must not be approached in inching mode!
Make sure that the RACO electrical cylinder is switched off by the system when the
limit switch is reached.
Danger of crushing!
Danger of crushing from extending cylinder!
Keep a safe distance between the RACO electrical cylinder and the mass being moved.
Revision: 03 2.2-11/1 154-45 -8

The function test must be carried out in inching mode to prevent damage if the limit switches are not
adjusted correctly. A separate grounding conductor must be connected for potential equalisation.
Da age hazard!
Electrical cylinders must not be used in systems that are protected by a "cathodic
electro-chemical corrosion protection". Exceptions are only possible after consulta-
tion with the manufacturer.
2.3.3 Aligning the RACO electrical cylinder
Following electrical installation, the RACO electrical cylinder must now be aligned.
Danger of da age!
Radial and torsion forces acting on the axis of the RACO electrical cylinder are not per-
mitted! Align the RACO electrical cylinder so that there are no radial and torsion forces
acting on the axis.
Align the RACO electrical cylinder as follows:
a) Loosen the screws attaching the bearing blocks to the system, and the lock-nut on the fork
head. Extend and retract the RACO electrical cylinder several times in “typing” operation until it
has seated properly and shows no more lateral movement.
b) Using a suitable measuring device, check that the RACO electrical cylinder is correctly aligned.
If the RACO electrical cylinder is not correctly aligned, you must use other suitable methods to align
the RACO electrical cylinder correctly.
Now tighten the screws attaching the bearing blocks, and the lock-nut on the fork head.
2.2.4 Co issioning
Only put the product into operation when it is established that the final product (a machine or construc-
tion for example) the RACO-product is assembled in corresponds to the country-specific regulations,
safety instructions and norms of application.
Commissioning may only be carried out if the RACO electrical cylinder:
a) does not exceed the nominal current in the loaded condition (see rating plate), observe the
correct switch-on time/operating mode,
b) is properly installed the built-in or external end-position switches are connected and adjusted,
c) the whole travel range has been tested in “typing” operation or – if possible – at low speed,
d) has been checked for proper condition with regard to installation and
e) the swivel foot brackets and the rod eye have been properly lubricated during installation.
f) Before putting into operation make sure all gaskets and fasteners are leak-proof.
Danger of da age!
Mechanical end-positions may not be approached during “typing” operation!
Ensure that the RACO electrical cylinder is switched off by the system controls on
reaching the end-position switch.
Revision: 03 2.2-12/1 154-45 -8

The device may only be put into operation with limit switches (internal or external) connected. The limit
switches must be set in such a way that the thrust tube comes to a standstill before the mechanical fi-
nal position at maximum speed.
Risk of injury caused by oving parts (thrust tube for exa ple)
Do not touch in moving parts during operation.
Do not linger in range of dangers in front of the thrust tube.
Before putting into operation make sure there are no persons in front of the thrust
tube.
The function and setting of the final position limitation must be checked in inching mode first. When
setting the final position limitation, system-related run-on must be taken into consideration depending
on the load and adjustment speed. This run-on can be several centimetres. At high setting speeds the
devices are usually equipped with a brake. However, run-on caused by the switching speed of the
brake still needs to be taken into consideration (60 - 120 mm/sec depending, brake switched by AC).
The precise approach of final and intermediate positions cannot be exactly reproduced under chan-
ging operating conditions in the case of RACO electrical cylinders with self-locking trapezoidal thread
spindles. It can fluctuate from a few millimetres to a few centimetres, depending on the run-in state
between spindle and nut, the condition of the lubricant and the load.
An electrical cylinder with a ball spindle system must never be moved against a fixed stop, whether in-
ternal or external. This damages the ball thread drive and will destroy it in the long term.
If it is possible that impermissible high impulse forces occur during travel towards the mechanical final
stop position, measures must be taken to ensure the moving masses are slowed down before the stop
is reached in order to protect the ball spindle system from damage.
At high travel speeds and large masses, abrupt acceleration and slowing (e.g. brake) must always be
avoided. A converter must be used to avoid the acceleration and slowing process through ramps.
During commissioning care must be taken that the motor current consumption under load does not ex-
ceed the rated current specified on the type plate for any length of time. Heed the switch-on
duration/mode of operation.
In the case of electrical cylinders with built-on gears or gear motors, particularly worm and flat gears,
the installation position specified in the order must always be heeded. If no specifications were made
or a different installation position is necessary, please contact our technicians at RACO.
To prevent any blocking or damage of the cylinder the internal end positions should never be reached.
By setting the limit switches the run-on have to be observed according the listed data in diagram at-
tached, so that the actuator stops before the end of the screw is reached.
Usuable stroke = no inal stroke – reserve!
Stroke reserve for co pact series type 6 size 2, 4, 6
Revision: 03 2.2-13/1 154-45 -8

2.2.4.1 Travel accuracy
Please note that due to the physical circumstances, the travel accuracy of spindle systems depends
on the relevant load and operating conditions, and is therefore not always identical or reproducible.
Differences ranging from millimetres up to as much as a centimetre are possible, depending on the
condition of the spindle and nut, the condition of the grease and the size of the load.
With RACO electrical cylinders however, you have the facility, by means of relevant accessories in the
electrical cylinder and associated controls, of achieving reproducible travel accuracies of up
to 0.05 mm.
Ensure that the RACO electrical cylinder cannot run on and butt up against the mechanical end-stop in
the cylinder.
If an accurate position is to be reached by the end-position switch, a stop or similar device must be
used. Care must be taken here to ensure that this mechanical stop cannot be approached at full travel
speed.
2.2.5 Operation
Electric shock caused by touching energized parts!
Severe injuries up to death.
Before working on the electric installation interrupt electric power supply and secure it
against resetting.
Risk of injury caused by oving parts (thrust tube for exa ple)
Crushes.
Do not touch in moving parts during operation.
Do not linger in range of dangers of the thrust tube.
Notice!
Pollution of environ ent
Outpouring lubrication when vertically installed!
Take appropriate measures in order to absorb outpouring lubrication and depollute
properly.
Notice!
Overheating of otor caused by overload!
Fire.
Consider technical specification like maximum rounds per minute, motor specifica-
tions and so on during operation.
Revision: 03 2.2-14/1 154-45 -8

2.2.6 Maintenance
To prevent problems, hazards and damage, RACO electrical cylinders must be checked for proper
function at regular intervals depending on the operating conditions. The area between the stripper
(guide cap) and the thrust tube that moves in relation to this must be cleaned in particular to carry out
a visual inspection for damage.
Motor
RACO special motors are maintenance-free. The maintenance instructions provided by the gear or
gear motor supplier must be heeded wherever gears are attached.
Spindle-nut syste
The cylinder type 6 (compact series), especially the spindle-nut system is equipped with a long life lub-
ricantion. A Re-lubrication of the spindle-nut system is not necessary for the estimated operation
period. The service life of the spindle-nut system can be increased by relubrication (replacement),
however.
Only for the compact series in size 7 (T6Q ) a re lubrication is recommend. Depending on the number
of cycle => 10.000 or after 3 years operation the grease can be put onto the actuator via the nipple on
the Rod eye. To make sure that the grease will cover the whole screw, a full stroke operation had to
carry out.
The installation position does not present any limitations in terms of lubrication. The devices can be in-
stalled in any position.
The electrical cylinders with trapezoidal thread spindle are usually equipped with a spring gear as a
seat for the spindle nut. Mechanical limitation of the spring travel prevents the springs moving to
"block". If electrical cylinders with spring gears certified to the ATEX directive are supplied, they must
be checked in the plant after 6 years of operation.
Note!
Further details of the different equipment variants are described separately in the fol-
lowing chapters.
Revision: 03 2.2-15/1 154-45 -8

Notice!
Damage caused by use of dissolver and aggressive cleaning supplies!
Destruction of gaskets and malfunction of product.
Only use water and mild cleaning supplies for cleaning.
Close all openings with appropriate protection caps.
Make sure all gaskets and closures are tight in order to avoid intrusion of wetness when cleaning,
