The product packaging is suitable for handling and lifting with
warehouse equipment.
Check the integrity of the packaging before handling.
• The product must be stored in a dry environment protected from
severe weather conditions
• Storage temperatures must be between -20°C and +80°C
• The product must always be handled with the rod completely
retracted.
• The product may only be lifted at the points shown in the figure.
• It is forbidden to use the rod for lifting the Series 3E
electromechanical cylinder.
When installing the component, make sure that there is no danger due
to possible uncontrolled mechanical movements.
The Series 3E electromechanical cylinder can only be installed by
specialised personnel or by trained personnel under the guidance and
supervision of qualified personnel.
Before starting the installation, check the direction of the rotation to
make the rod extend and refract.
It is strongly reccomended not to paint the Series 3E electromechanical
cylinder.
Accidental falling and/or crushing of the packaging may compromise the
functionality of the product and cause serious injury to the handler.
• It is forbidden to use the rear end cap to lift the product, in order to
prevent the rod from coming out of the cylinder body due to the
reversibility of the recirculating ball screws.
CAUTION: Vertical or slanted mounting of the Series 3E
electromechanical cylinder, with the rod facing downwards, can be
dangerous. The rod could come out of the Series 3E electromechanical
cylinder at an uncontrolled speed due to the reversibility of the
movement of the recirculating ball screw it contains.
CAUTION: Constraining of the actuator by any accessory must always
be carried out by checking the correct alignment of the accessory to
the final application.
Incorrect assembly with misalignments and/or forcing can
compromise the performance and durability of the actuator.

STEP 1
Assemble the pulley (4) and the locking set (3) on the tang of the Series
3E cylinder (1) according to the instructions in the paragraph "ASSEMBLING
NON SELF-CENTRING LOCKING SETS”.
STEP 2
Proceed by fixing the front flange (5), onto the Series 3E electromechanical
cylinder (1).
As shown in the diagram, the cylinder is equipped with a pin on the rear
interface, designed to guarantee the correct orientation of the accessory
during assembly.
Pay particular attention to the sign on the flange (5) which marks the
side opposite the one on which to interface the motor and cylinder.
Then proceed by tightening the nuts (8) to fix the motor flange (5) in
position.
Recommended nut tightening torque 0,6 Nm.
STEP 3
Continue assembling the kit by assembling the motor pulley (9) and the
locking set (11) on the motor shaft (2) according to the instructions in the
paragraph "ASSEMBLING THE SELF-CENTRING LOCKING SET AND ADJUSTING
THE PULLEY".
NB: if you are assembling a PM-3E-20-0017 kit for connecting a NEMA
17 stepper motor with the size 20 Series 3E electromechanical cylinder,
this step must be carried out by fitting the motor (2) in advance in the
front flange (5).
For any other in-parallel connection kit it is possible to pre-assemble the
pulley (9) and the locking set (11) on the motor and then fit everything
on the flange (5).

Commissioning
CAUTION: Commissioning of the Series 3E electromechanical
cylinder must only take place after having ascertained that
the system or the machine in which it is installed meets the
country-specific regulations, safety regulations and applicable
standards.
Before carrying out the electrical connection of the motor, check that the
assembly of all interface components is correct.
Make sure the range of motion is free from obstacles.
Conncect the electrical connection afterwards.
WARNING - Electrical hazard
• Before commissioning, make sure that all connectors are correctly
concected;
• Risk of motor short circuit due to the presence of openings. Possibility of
damage to the motor due to penetration of liquids and foreign objects;
• Check the correct closure of the connectors. Possibility of collision
due to incorrect set-up or positioning of connectors or limit switches.
Possibility of damage to the product.
WARNING - Risk of injury
• Risk of injury from moving parts;
• Do not grab moving parts during operation;
• Do not stand in the danger zone in front of the Series 3E
electromechanical cylinder;
• Before starting, make sure that no one is in front of the Series 3E
electromechanical cylinder;
Check that you have set up the strokes accurately to avoid collision of the
product with limit switches.
• Respect the maximum stroke of the Series 3E electromechanical cylinder.
• Check that the application of the operating conditions is correct.
In particular, pay attention to: ambient temperature, load conditions number
of revolutions and maximum stroke of the Series 3E electromechanical
Cylinder. Precise directions are contained in the manual and in the catalogue
information.
For particular operating conditions, contact the technical service. Before
using the Series 3E electromechanical cylinder in production conditions, test
the entire stroke at very low speed
Only put the product into operation after successfully carrying out a
Functioning test under production conditions, with positive outcome.
CAUTION: The Series 3E electromechanical cylinder is not
equipped with an emergency end-of-stroke cushioning system.
It is recommended to avoid end-of-stroke shocks, in order to
preserve the integrity of the product.
Assembly and adjustment of the position of the CSD magnetic proximity switches
The Series 3E cylinder is equipped with 8 sensor slots (2 per side), into
which sensors (proximity switches) can be inserted axially form both the
front and rear interfaces of the actuator.
For assembly, insert the switch axially into the appropritate slots on the
Series 3E electromechanical cylinder.
Finally, lock by tightening the nut supplied.
NB: some accessories/kits could obstruct the slots making it impossible
to insert the switch; it is therefore recommended to fit it in advance, and
then fix it in position at the right moment. For reading at the limit switch,
it is recommended to pay attention to the orientation of the switch, as it
could protrude from the cylinder.

Assembly of self-centring locking device and pulley adjustment
Check that all contact surfaces are clean and lightly oiled (do not use
“Molykote” or molybdenum disulphide based lubricants). Position the
locking set on the pulley hub, taking care to keep all the locking set
within the DC length of the hub. Assemble it on the motor shaft taking
care to maintain the dimension (DC) as indicated in the table.
It is sufficient to fit it on the cylinder shaft up to the rabbet on the tang,
making sure not to force it axially.
Then tighten gradually and evenly, according to the tightening torques
(MS) shown in the table.
Being careful to pass from one screw to its opposite (cross diagram),
proceed as follows:
- hand tighten the assembly screws until contact is made with the surface
- check the positioning of the hub on the shaft
- tighten the screws to approximately half of the recommended MS
tightening torque
- repeat the operation until the recommended tightening torque is
reached, using the torque wrench
- check that all screws have reached the specified tightening torque.
If the locking set is reused, screws and conical parts must be oiled d x D
MS [Nm] before proceeding with assembly.
NB: the dimensions shown in the table refer to the motors in the Camozzi
catalogue, the compartibility of the kits with different motors is not
guaranteed.
