3 • INSTALLATION AND CONNECTION
This section contains the instructions necessary
for correct installation of the GF_VEDO ML
into the machine control panel 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.
Terminal power supply
• The GF_VEDO ML 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
• Theoperatorterminalispoweredat24VDC±25%.
Power supplies beyond this range may seriously
damage the product. Carefully check the power
supply before applying it to the product.
• Thepowersupplytotheelectronicequipmentonthe
switchboards must always come directly from an
isolation device with a fuse.
• Theterminal’selectricalconnectionsmusthavea
path separated from the system power cables.
• The electronic instruments and electromechanical
power devices such as relays, contactors, solenoid
valves, etc., must always be powered by separate
lines.
• Makesurethattheoperatorterminalisproperlyand
sufficiently grounded.
Failure to ground or to sufficiently ground it may
make operation unstable or cause the product to ma
function due to excess interference.
- the voltage between neutral and earth must not be >1 V
- the resistance must be <6 Ohm.
• If the mains voltage fluctuates strongly, use a 
voltage stabilizer.
• In the proximity of high frequency generators or arc
welders, use adequate mains filters.
During use
• Theemergencybuttonandothersafetydevicesmust
be guaranteed by the installer and are not controlled by
the operator terminal.
• Whenpressingkeys,touchscreenordisplay,donot
use sharp objects or objects that might damage the
product (nails, screwdrivers, pointed objects).
Service and Maintenance
• Onlytrainedpersonnelarequalifiedtoremoveand
replace the operator panel.
• OnlyGefranpersonnelorpersonnelauthorizedby
Gefran may do repairs.
• Useonlyasoftdampclothtocleanthefrontpaneland
the screen.
SWITCH OFF THE POWER before cleaning the opera-
tor terminal.
• Incorrectreplacementofthebattery(whereprovided)
may cause the product to malfunction.
Use only the batteries indicated by the builder.
Disposal
• Theterminaloritspartsmustbedisposedofincom-
pliance with the laws in the country of installation.
• Someofthecomponentsintheproductmayharmthe
environment if incorrectly disposed of.

reverses and short circuits by a resettable fuse. 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.
Ground the devices in a manner conforming to applicable standards and regulations.

4.4.2 Autostart Port
GF_VEDO ML uses the optional Autostart output to activate an external relay by means of a programmable
internal timer. Activation requires that only the relay be powered, and to run the external devices you have to use
the free contact of the relay (activation time approx. 10 seconds).
We recommend the use of 24 V d.c. relays with a maximum of 100 mA at the coil.

4.4.3 Ethernet ports
GF_VEDO ML uses Ethernet ports to dialog via IEEE 802.3 Ethernet protocol. Each Ethernet port can dialog at
10/100 Mbps using an 8-pin RJ45 connector with LED.
We recommend an Ethernet Base-T with braided leads (CAT. 6). The wiring scheme must conform to standard
TIA/EIA-T568-A. Signal assignment is shown in Table 6.

4.4.5 RS-485 Port
GF_VEDO ML uses the RS-485 port to dialog according to OSI specifications at the physical level defined by
standard EIA-485.
The RS-485 port is optically isolated and allows dialog from 9.6 kBaud to 115 kBaud via an RJ10 4p4c connector
(Registered Jack type 10 with 4 positions and 4 contacts).
Signal assignment is shown in Table 8.

4.4.4 RS-232 Port (optional)
RS-232 port lets the GF_VEDO ML dialog with RS-232 serial transmission protocol at a baud rate from 9.6 kBaud
to 115 kBaud.
The RS-232 port is not optically isolated and uses a 9-pin (male) D-sub connector. Signal assignment is shown in
Table 7.

4.4.6 FIELDBUS Port:Option CAN
The optional CAN port lets GF_VEDO ML dialog via the serial standard (ISO 11898-1 of 2003) for the CAN
(Controller Area Network) field bus, also known as CAN-bus.
This protocol is specifically designed for excellent operation even in environments with strong electromagnetic
noise, and can use a balanced potential line such as an RS-485 as means of transmission.
In particular, GF_VEDO ML implements the CANOpen Layer 2 standard. The CAN port is optically isolated and
uses a 9-pin (male) D-sub connector.
Signal assignment is shown in Table 9.
Thebuslinemustbeterminatedatbothandbya120Ω1/4WresistorplacedacrossCAN-MandCAN-L,as

4.4.7 USB Port
GF_VEDO ML uses USB ports to dialog via USB (Universal Serial Bus) serial communication standard.
GF_VEDO ML terminals support version USB 2.0 (transmission up to 480 Mbit/s).
The USB port connector is type USB-A (4 pins). Signal assignment is shown in Table 10.

4.4.9 Matrix Keyboard port (KEY & LED)
GF_VEDO ML uses the KEY & LED port to communicate with series TF keyboards.
It uses a high-speed full-duplex synchronous serial interface (SPI) with proprietary communication protocol.
This allows scanning of the key matrix and control of off/on status of LEDs on the keyboard.
The connector is an 8-pin RJ45 without LED, which allows keyboard communication and power.
Signal assignment is shown in Table 11.
Cable length can be a maximum of 1 meter.
4.4.10 Mouse and Keyboard PS2 port
The PS2 port connects the GF_VEDO ML to keyboards and mice conforming to PS2 standard.
Two mini-DIN 6-pin female connectors are used (green: Mouse, violet: Keyboard).
Signal assignment is shown in Tables 12 and Table 13.
