2 • INSTALLATION AND CONNECTION
This section contains the instructions necessary
for correct installation of the GF_VEDO TL 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 GF_VEDO TL 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 GF_VEDO TL 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:

Instrument power supply
• 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 tampering, neglect, improper use or any
use which does not conform to the characte-
ristics of the controller and to the indica-
tions given in these Instructions for Use.

When necessary, replace the battery as follows:
• get a replacement battery (button-type, 24 mm diameter, 3V lithium (CR2430))
• switch off the system by disconnecting it from the outside power supply.
• remove the battery
• dispose of the old lithium battery in compliance with regulations
• insert the new battery as shown in Figure 25
• switch on the system.
Note:
if the battery is replaced quickly(in less than 15 minutes) there is no loss of data maintained by the backup battery.
