ENERAL DESCRIPTION
G
The CYBELEC numerical controls are specifically intended for sheet metal
working machines.
Depending on the software they will be installed on press-brakes
(synchronized or not), foldintg presses or tube bending machines.
The machines equipped with these numerical controls are dangerous and are
subject to the Machine Directives of the European Community.
It is the responsibility of the machine manufacturers to ensure that the safety
precautions relative to these machines are respected.
The numerical control is not a safety device.
CYBELEC numerical controls are assimilated with programmable
automatons and are subject to the “Low voltage” (73/23/CEE) and
"Electromagnetic Compatibility" (89/336/CEE) Directives, but are not
subject to the Machine Directives (89/392/CEE).
The CYBELEC numerical controls conform with the above standards (see
Installation chapter).
ECHNICAL CHARACTERISTICS
T
The technical characteristics of the numerical control can be found in the
document called CYBELEC DATA SHEET which is annexed to this
document..
ANDLING, UNPACKING, STORAGE
H
CYBELEC numerical controls are delivered in a packaging destined for
transport by train, road or air.
If the numerical control has to be transported at a later date, it must be packed
in the original container.
Storage characteristics
Storage of the numerical control should be if possible in the original
container.
Temperature: - 25°C à + 55 °C
Humidity: 10 % à 90 %
PAGE 3
Unpacking, handling
Due to the weight and size of the apparatus, two persons are necessary to take
it out of the container, to move it and to fix it.
Avoid placing the apparatus where there is a risk of objects or metallic (or
other) particles being projected. They could enter the apparatus by the
connection opening and cause a break-down.
The apparatus should be held by the casing in one of the following ways:
OUNTING
M
The numerical control must be fixed using the 4 M6 screws to a metallic
bracket. The intermediate plate (from mid-1997 on) must be held between the
bracket and the numerical control. Once mounting is finished and the cables
are attached to the intermediate plate with the ties, it is recommended to
screw this plate on to the bracket. Preferably 2 small screws with conical
heads (so that they do not project beyond the intermediate plate) placed from
underneath.
Attention:
The bearing surface against the bracket must not be painted.
See also the Connection precautions chapter which follows.

Respect of standards CYBELEC numerical controls comply with the "Electromagnetic
Guarantee CYBELEC’s responsibility under the guarantee is limited to the components
compatibility" EMC 89/336/CE directives for as much as the connection
instructions are respected (see following paragraph), that the electrical cabinet
is made respecting the standards EN50081-2 and EN 50082-2 and that the
subsidiary components used also comply with the "Electromagnetic
compatibility" EMC 89/336/CE directives.
supplied. All claims under guarantee are annulled if the adjoined connection
recommendations are not or only partially respected. This is a complement to
the conditions of guarantee in the sales contract.
You will find below some examples of precautions to be taken.
This list is not exhaustive and does not replace the EMC tests.
This document does not deal with electrical safety (EN60204-1 and
EN 60950), which must be realized and complied with by the manufacturer.

ENERAL INFORMATION
Interfering elements must be protected / filtered.
Interfering elements means, "switching" power supplies, AC or DC powered
servo-amplifiers, relay/valve coils, input transformers, high voltage cables,
etc.
The deparasiting elements are placed as near as possible to the interfering
element. You should use preferably relay supports and deparasiting plugs.
(for valves) available commercially, specially designed for this deparasiting
function.
Sensitive elements must be protected and placed as far as possible
from the interfering elements.
Sensitive elements are for example the analogic inputs with high impedance,
the low voltage (0 to 24VDC) input/output cables, the analogic signals etc.

ISPOSITION AND CHARACTERISTICS OF THE
Power cables
Low voltage

ELEMENTS IN THE ELECTRICAL CABINET
Cabinet base
Cables
Low voltage
The basic principles of electromagnetic
protection for maximum diffusion of the
interference in the electrical masse. To achieve
this:
- The base plate of the cabinet must not be
isolating (painted), but preferably in anodised
metal or aluminium.
- The metallic elements (transformers, filters,
etc. ) are fixed directly on to the base plate.
basic principle:
each voltage must be placed in a separate
"conduit."
It is thus indispensable to separate the paths of
the low voltage and hi gh voltage cables.
They must be as far away from each other as
possible.
To do this the each voltage range will have its
own conduit.
Power
Terminals
If it is not possible to avoid them coming close,
it should only be for a short distance and they
should preferable make a 90° crossing.
In the same way , the power terminals must be
as far away as possible from the “sensitive”
terminals.
If necessary the “sensitive” terminals should be
covered by a metallic lid which acts as a
Faraday cage.
PAGE 6 BASIC TECHNICAL INFORMATION
Low voltage sensitive
elements
Servo-ampli.
A power servo-ampli is an important source of
electromagnetic interference.
Particular attention should be taken for its
connection and necessary protections.
They will be placed as far as possible from the
sensitive elements and “sensitive” terminals.
Servo-amplis
Supply transformer
for the servo-amplis
The servo-amplifier will be covered by a metallic
casing which acts as a Faraday cage.
By experience, it is recommended to place a
filter on the servo-amplifier power supply. The
filter and the power supply are placed as near as
possible to the servo-amplifiers.
The connections of the motors to the servoamplifiers must be shielded.
The shield must cover the power cables, the
position captor and the motors inside the
electrical cabinet up to the servo-amplifiers. The
power cables and the position captor must not be
interrupted.
The earthing of the shield of these cables must be
done as near as possible to the servo-amplifier
(see further on Connection precautions, Basic
rules ).
Transformers
Switching power
supply
Power supply of the
numerical control
If these measures prove insufficient, it will then
be necessary to place a filter at the servoamplifier output.
Often in this case, the shield is no longer
necessary for the motor cables.
In the case of DC motors, the output filter
improves the motor capacity and reduces overall
heating.
These elements should be placed as far as
possible from the sensitive zones.
The switching power supply will comply with
the EMC standards.
In some countries, the main power supply can be
subject to major variations.
Such disturbances can cause inconveniences to
the numerical control.
In such cases it is recommended to install an
uninterruptible power supply (UPS) on the
supply line of the DNC.

Cable earthing
A ground wire (0.75 mm2) soldered to the shield and
connected to a ground terminal or to the ground plate of
the electrical box is electrically correct but for EMC
immunity this method is not adequate and must not be
used.
Min 3 cms
Max 2 - 3 cm
This is valid for all the analog wires in the electrical cabinet (i.e. MVP 400,
servo-amplifiers, hydraulic amplifier, etc.). These analog wires must be
shielded and grounded on both sides as pictures shown hereafter.
The cable shield should be connected to ground with the
most important surface.
The length of the unshielded wires must be as short as
possible.
Special profiles for shields grounding are available. This type of solution
helps in the wiring efficiency (speed and quality). The pictures below show an
example of such alternatives.

This shows an earthing possibility for incoming
shielded cables.
An other solution would be similar as practiced in the DNC. The cables
bundle may be grounded at one point on the ground plate of the electrical
box.

Each shield must be connected to the cabinet mass by means of a small
metallic plate which serves also as a cable clamp (see above). In this
case it is important that the base plate of the electrical cabinet is made
either of anodised metal or aluminium.
It is possible to use a metallic stuffing box (or other clamping system)
clamped directly on to the shield (attention, the piece which clamps
the cable must also be metallic and not isolating).

The shielded cables destined for the power (servo-amplis) or
measurement signals must not be interrupted (avoid passing over the
intermediate terminals in the electrical cabinet).
They must be away from the interfering elements and high voltage
cables.

several terminals in the electrical cabinet which are supplied by one or
several conductors with a sufficient section).
The 0V is not identical to the earth.
A 0V exists for each voltage.
The 0V must be connected to the earth at one point only, using a
conductor with a sufficient section (see fig below).
Each 0V must be connected separately by a wire with a sufficient

Position of suppressors
The position of suppressors must be as near as possible of the noise
generator.
It is illusory to think to have a good protection if the suppressor is mounted in
the electrical box and the noise generator 5 meters away like an electro-valve.
In case of elements such electrovalves, the suppressors
must
be mounted in
the plug itself or with an intermediate suppressors as shown in the next 2
pictures. For the relays, the suppressor must be mounted on the socket itself
or preferably use a relay with included suppressors.
RC on MVP 40x
It is very important to install the RC element on the MVP 40x. This RC
element does not replace the noise suppressor, which still must be mounted in
the pressure valve.

Figure 1 represents how to prepare a cable.
The cable is stripped for a length of 3 to 4 cm then connected to the
plug.
An incision (exposing the shield) must be made between 30 and 70 cm
in relation to the end of the cable in order to easily connect it to the
DNC.
At this place, the cable is stripped for a distance of ~ 8 cm in such a
way that only the insulation is removed exposing the cable shield.

OUNTING THE SUB
For maximum immunity from interference exterior to your equipment, the
link plugs must be cabled with great care respecting as much as possible the
following proc edure.
Important It is only in this way that the contact with the shielding and the cable
support will resist any ulterior manipulations.
!
Cut the protective sheath over a sufficient distance ~50 mm, then
remove it. Cut the shielding.
-D
PLUGS
!
Expose the shielding by cutting a “window” of 5 mm on half of the
cable circumference.
In this way the shielding will stay in place and will not “fray”. The risk
of tearing is also diminished.
!
Fix the cable on to the casing by the shielding.
It is necessary to use a metallic casing.

The maintenance of the numerical control is limited to regularly changing the
filters and cleaning the exterior.
Changing the filters
It is important to change regularly (once a month) the filters in the numerical
control ventilators. If this maintenance is neglected, the numerical control can
over heat and provoke misfunctionning which may be irreversible.
! Cut the main power supply.
! Unscrew the 4 screws on the protection grill.
! Change the filter.
! Replace the protection grill.
Cleaning the DNC
!
Cut the power supply
!
Clean the keyboard, the casing and the rear panel with a damp cloth
and liquid soap (this is what is best !).
Dry with a clean dry cloth.
Never use alcohol based products, or solvents,
(trichlorethylene, thinner, acetone, benzene, etc.).

! Any intervention in the numerical control must only be realized by a
qualified technician..
! Before any intervention, the owner or the technician MUST save the
numerical control data.
! When connecting or removing a connector in the DNC, changing a
board or any other manipulation it must only be done with the DNC
disconnected from the power supply.
Attention, even when disconnected, the possibility of electrical
discharges remains, especially within the cathode screen housing.
! When handling boards, they must be conserved in the antistatic
packaging until the last moment. The technician will take all the
necessary precautions to avoid any electrostatic discharges (earthing
by an antistatic bracelet for example).
! If certain measures have to be realized with the current on, the
technician must insure that the safety earth conductors are correctly
connected.
! If the numerical control is equipped with cooling ventilators, their
functioning must be controlled at the end of the intervention, when the
rear panel has been put back in place.
