2 • INSTALLATION AND CONNECTION
This section contains the instructions necessa-
ry for correct installation of the GF_VEDO HL
into the machine control panel or the host
system and for correct connection of the con-
troller power supply, inputs, outputs and inter-
faces.
Before proceeding with installation read
the following warnings carefully!
Remember that lack of observation of these
warnings could lead to problems of electri-
cal safety and electromagnetic compatibili-
ty, as well as invalidating the warranty.
Electrical 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 opera-
tor. 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 machi-
ne structure.
• if the GF_VEDO ML 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 explo-
sive environments; it may be connected to equipment
operating in such atmospheres only by means of appro-
priate 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 EEC Directive 2004/108/CE.

Instrument power supply
• The power supply to the electronic equipment on the
switchboards must always come directly from an isola-
tion device with a fuse for the instrument part.
• The electronic instruments and electromechanical
power devices such as relays, contactors, solenoid val-
ves, etc., must always be powered by separate lines.
• When the electronic instrument power supply is stron-
gly 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 ear-
thed in one point only.
• To connect the control outputs, alarm ( c o n t a c t o r s ,
solenoid valves, motors, fans, etc.), fit RC groups (resi-
stance and condensers in series) in parallel to the induc-
tive 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 induc-
tive loads that operate in Direct Current.
GEFRAN S.p.A. declines all responsibility
for any damage to persons or property
caused by tampering, 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.

3.5.7 CAN port
The optional CAN port lets GF_VEDO HL 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 HL implements the CANOpen Layer 2 standard. The CAN port is optically isolated and
uses a 6-pin (male) D-sub connector.
Signal assignment is shown in Table 12.
An approved CAN cable is recommended for the connection. You have to add a termination (at the ends of the
CAN line) by short circuiting pins 1-2 of the connector.
642
531
3.5.8 External Battery Port
The external battery port lets you connect the GF_VEDO HL terminals to a battery to save BIOS data and data
stored in static RAM.
A 2-pin Modu II (AMP) connector is used.
The battery (NOT rechargeable) must be between 3V and 3.6 V.
Use the external battery only when the internal battery is not connected to the terminal.

3.5.10 Matrix Keyboard port (KEY & LED)
GF_VEDO HL 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 15.
Cable length can be a maximum of 1 metre.
3.5.11 Mouse and Keyboard PS2 port
The PS2 port connects the GF_VEDO HL 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 16 and Table 17.

Figure 21 - Access to internal resources of GF_VEDO HL terminals
3.6.1 System memory: SODIMM
GF_VEDO HL has a DDR1 SODIMM (Small Outline Dual In-line Memory Module) system memory, which is more
compact than normal DIMM.
3.6.2 Mass memory: DOM
GF_VEDO HL terminals are equipped with mass memory that contains the operating system and user data.
Each terminal has a solid state disk with Disk On Module (DOM) IDE AT compatible interface.
3.6 Access to internal system resources
You can replace the battery and configure the COM3 serial by removing the rear cover of the terminal as shown in
Figure 21. TURN OFF the GF_VEDO HL terminal before loosening the screws.

3.6.3 Internal battery
The GF_VEDO HL panels use an internal lithium battery (non-rechargeable; replaceable).
This lets you maintain data in the static RAM memory when the GF_VEDO HL is switched off (for a maximum of 3
years).
To replace the battery when necessary, do as follows:
· get a replacement battery: 24 mm diameter button battery, 3V lithium (CR2430)
· switch off the system by disconnecting it from the external power supply
· access the battery as shown in Figure 22
· remove the battery
· follow the rules for disposal of lithium batteries
· insert the new battery as shown in Figure 22
· switch on the system
Note: If the battery is replaced rapidly (in less than 15 minutes), there is no loss of data maintained by the buffer
battery.
