Preliminary warnings
Read the following preliminary warnings before
installing and using the operator terminals.
Doing so makes start-up quicker and lets you
avoid some problems that might be mistaken
for malfunctions or limitations of the terminal.
• Immediately after unpacking the product, make a note
of the order code and the other identification data given
on the label affixed to the outside of the container and
copy them to the table below.
These details must always be kept close at hand and
referred to the personnel involved in the event of help
from Gefran Customer Service Assistance.
• Check that the terminal is in perfect condition and was
not damaged during shipment. Make sure that the pac-
kage also contains the fastening accessories.
Any inconsistencies, omissions or evident signs of
damage should be reported immediately to your Gefran
sales agent.
• Check that the order code corresponds with the confi-
guration requested for the application the terminal is
needed for, referring to Section: “Technical - Commercial

1 • PRELIMINARY INSTRUCTIONS
This section contains information and warnings of a general nature which should be read before procee-
ding with terminal installation, configuration and use.
General description
The operator terminals are a compact and low-cost
solution for machine control.
A single product integrates machine cycle control
[SoftPLC] and graphic page display [SCADA], allowing
quick and low-cost creation of many automation solu-
tions.
The operator terminals creates the machine/operator
interface by means of LCD monitor, touch-screen, and a
wide variety of peripheral I/Os.
The operator terminals are applied mainly to machine
control for packaging, metals, wood and plastic applica-
tions. This Installation Guide describes the main charac-
teristics of the operator panels and refers to the follo-
wing models:
GF_VEDO EL35CT operator interface with 3.5” color touch-screen LCD TFT Ethernet port,
integrated I/Os [optional], Fieldbus port [optional], USB port [optional]
GF_VEDO EL57CT operator interface with 5.7” color touch-screen LCD TFT Ethernet port,
integrated I/Os [optional], Fieldbus port [optional], USB port [optional]

2 • INSTALLAZIONE e COLLEGAMENTO
This section contains the instructions necessary
for correct installation of the terminals into the
machine control panel or the host system and
for correct connection of the controller power
supply, inputs, outputs and interfaces.
Before proceeding with installation read the
following warnings carefully!
Remember that lack of observation of these
warnings could lead to problems of electrical
safety and electromagnetic compatibility, as
well as invalidating the warranty.
Electrical power supply
• the terminal is NOT equipped with an On/Off
switch: the user must provide a two-phase
disconnecting switch that conforms to the required
safety standards (CE marking), to cut off the power
supply upstream of the terminal.
The switch must be located in the immediate vicinity of
the terminal and must be within easy reach of the
operator.
One switch may control more than one terminal
• if the terminal is connected to NOT isolated electrical
equipment (e.g. thermocouples), the earth connection
must be made with a specific conductor to prevent the
connection itself from coming directly through the
machine structure.
• if the terminal is used in applications with risk
of damage to persons, machinery or materials, it is
essential to connect it up to auxiliary alarm
equipment. It is advisable to make sure that alarm
signals are also triggered during normal operation.
The terminal must NOT be installed in flammable or
explosive environments; it may be connected to
equipment operating in such atmospheres only by
means of appropriate and adequate types of
interface, conforming to the applicable safety
standards.
Notes Concerning Electrical Safety and
Electromagnetic Compatibility:
CE MARKING: EMC Conformity (electromagnetic
compatibility)
in accordance with Directive 2004/108/CE.
The terminals are mainly designed to operate in indu-
strial environments, installed on the switch boards or
control panels of productive process machines or
plants. As regards electromagnetic compatibility, the
strictest generic standards have been adopted, as indi-
cated in the table below.
BT Conformity (low voltage) in accordance with
Directive 2006/95/CE.

Instrument power supply
Installation categoryII and pollution degree 2.
• The power supply to the electronic equipment on the
switchboards must always come directly from an
isolation device with a fuse for the instrument part.
• The electronic instruments and electromechanical
power devices such as relays, contactors, solenoid
valves, etc., must always be powered by separate
lines.
• When the electronic instrument power supply is
strongly disturbed by voltage problems from power
units or motors, an isolation transformer should be
used for the controllers only, earthing the screen.
• It is essential that the plant has a good earth
connection:
- the voltage between neutral and earth must not be >1V
- the resistance must be < 6Ω;
• If the mains voltage fluctuates strongly, use a voltage
stabilizer.
• In the proximity of high frequency generators or arc
welders, use adequate mains filters.
• The power supply lines must be separate from the
instrument input and output ones.
Inputs and outputs connection
• To connect the analogue inputs, strain gauge,
linear, (TC, RTD) the following is necessary:
- physically separate the input cables from those of the
power supply, the outputs and the power connections.
- use woven and screened cables, with the screen
earthed in one point only.
• To connect the control outputs, alarm(contactors,
solenoid valves, motors, fans, etc.), fit RC groups
(resistance and condensers in series) in parallel to
the inductive loads that operate in Alternating
Current.
(Note: all the condensers must conform to VDE
(class X2) standards and withstand a voltage of at
least 220V AC. The resistances must be at least 2W).
• Fit a 1N4007 diode in parallel with the coil of the
inductive loads that operate in Direct Current.
GEFRAN S.p.A. declines all responsibility for any
damage to persons or property caused by tampe-
ring, neglect, improper use or any use which
does not conform to the characteristics of
the controller and to the indications given in
these Instructions for Use.

3.5.1 Power supply port
The internal power supply (24Vdc, -15% +20%) is galvanically isolated and protected against polarity reverses and
short circuits. The panel has a power terminal. The connector diagram is shown in Figure 11.
Note:
check that the power supply is able to deliver the power needed for correct operation of the device.
The device must always be grounded. Grounding helps limit the effects of electromagnetic noise on the control
system. All electronic devices of the control system must be grounded. Ground the devices in a manner conforming
to applicable standards and regulations.
Max consumption GF_VEDO EL35CT: Max consumption GF_VEDO EL57CT:
• (without integrated I/O) 240mA, 5W • (without integrated I/O) 480mA, 8.5W
• (with integrated I/O) 360mA, 7W • (with integrated I/O) 490mA, 9W
