1 • PRELIMINARY INSTRUCTIONS
1.1 Profile
The Gefran GFW-Xtra power controller combines the functio-
nality of a single, two or three phase solid-state power unit and
controller with the benefits of the unique integrated overcurrent
fault protection function.
The fault protection eliminates the need for extra-rapid fuses,
reducing machine downtime and the cost of replacing fuse fai-
lures.
It does so by instantaneously monitoring load current, cutting the
power if the load reaches a pre-set threshold and isolating the
power switching devices.
In applications susceptible to intermittent short-circuits and over-
loads, the Gefran Xtra power controller can be programmed to
restore power automatically when the fault has cleared, preven-
ting complete process shutdown and maintaining production.
Alternatively, power can be manually restored, locally or remo-
tely.
A soft-start ramp is applied when the current is restored, to pre-
vent system damage in the event that the fault is not effectively
cleared.
The GFW-Xtra controller is compact, modular and optimised to
control virtually any type of restive heating system in a wide ran-
ge of industrial applications.
Impressive functionality is assured by a comprehensive array of
options that are configurable with intuitive, guided-set-up, PC-
based Windowstm software.
GFW-Xtra always provides an RS485 serial connection with
Modbus RTU protocol to control currents, voltages, powers, load
status, and device status from the supervisor terminal (HMI) or
PLC.
A second (optional) communication port is offered that lets you
choose from among the following Fieldbuses: Modbus RTU,
Profibus DP, CanOpen, Modbus-TCP, Ethernet IP, EtherCAT.
The section contains general information and
warnings to be read before installing, configuring
andusingthecontroller.
1.2 General DescriPtion
GFW is single-zone advanced solid state power unit, extremely
compact, equipped with different optional functions; it offers an
exclusive combination of performance, reliability, and flexibility.
In particular, this new line of Gefran solid state relays is the
ideal solution for sectors demanding high performance and
continuity of service, such as:
• Metal heat treating furnaces
• Vacuum furnaces with graphite elements
• High-temperature furnaces
• Boosters for glass lines
• Quick cutting on blow molding lines
• Machines and lines with unwanted current peaks and arcs
• “Fuse-free” solutions
The modules Series GFW are based on an extremely versatile
hardware and software platform, with options to select the best
I/O configuration for your system.
GFW is used for the power control of single-phase, Dual-Phase
and 3-phase loads, including resistive loads with high and low
temperature coefficient, short wave IR lamps, or transformer
primaries.

malfunctionsorlimitationsofthecontroller.
Immediately after unpacking the unit, check the order code
and the other data on the label attached to the outside of the
container.
Write them on the following table.
This data must always be available and given to Gefran
Customer Care representatives if technical service is needed.
Check that the controller is in perfect condition, was not
damaged during shipment, and that the package also contains
the CD that contains other useful information such as the
“Configuration and Programming” manual, memory map etc...
Immediately report any errors, shortages, or signs of damage to
your Gefran dealer.
Check that the order code matches the configuration requested
for the intended application by consulting the section:

CAREFULLY READ THE FOLLOWING WARNINGS
BEFORE INSTALLING THE INSTRUMENT!
Disregard of such warnings could create electrical
safety and electromagnetic compatibility
problems, as well as void the warranty�
2.1 electrical Power suPPly
• the controller DOES NOT have an On/Off switch: the user
must install switch/isolator conforming to safety requisites (CE
mark) to cut off the power supply up-line of the controller.
The switch must be installed in the immediate vicinity of the
controller in easy reach of the operator.
A single switch can be used for multiple devices.
* the earth connection must be made with a specific lead
• if the product is used in applications with risk of harm to
persons or damage to machines or materials, it MUST be
equipped with auxiliary alarm devices.
It is advisable to provide the ability to check for tripped alarms
during regular operation.
DO NOT install the product in rooms with hazardous
(inflammable or explosive) atmosphere; it may be connected to
elements that operated in such atmosphere only by means of
appropriate interfaces that conform to current safety standards.
2.2 notes on electrical safety anD
electromaGnetic comPatibility:
2�2�1 MARCATURA CE: EMC
(electromagnetic compatibility) conformity
in compliance with Directive 89/336/CEE and following
modifications.
Series GFW are mainly intended for industrial use, installed
on panels or control panels of production process machines or
systems.
For purposes of electromagnetic compatibility, the most
restrictive generic standards have been adopted, as shown on
the table.
2�2�2 LV (low voltage) conformity
in compliance with Directive 2006/95/CE.
EMC compliance has been verified with respect to
the information in Tables 1 and 2.
2 • INSTALLATION AND CONNECTION
2.3 recommenDations for correct installation
for PurPoses of emc
2�3�1 Instrument power supply
• The power supply for the electronic instrumentation on the
panels must always come directly from a cut-off device with
fuse for the instrument part.
• Electronic instrumentation and electromechanical power
devices such as relays, contactors, solenoids, etc., MUST
ALWAYS be powered by separate lines.
• When the power supply line of electronic instruments is
heavily disturbed by switching of thyristor power groups or
by motors, you should use an isolation transformer only for
the controllers, grounding its sheathing.
• It is important for the system to be well-grounded:
- voltage between neutral and ground must not be > 1V
 -Ohmicresistancemustbe<6Ω;
• If the grid voltage is highly unstable, use a voltage stabilizer.
• In proximity of high-frequency generators or arc welders,
use adequate grid filters.
• The power supply lines must be separate from instrument
input and output lines.
• Supply from Class II or from limited energy source
2�3�2 Input and output connections
Before connecting or disconnecting any connection, always
check that the power and control cables are isolated from
voltage
Appropriate devices must be provided: fuses or automatic
switches to protect power lines.
The fuses present in the module function solely as a protection
for the GFW semiconductors.
• Connected outside circuits must be doubly isolated.
• To connect analog inputs, strain gauges, linears, (TC, RTD),
you have to:
- physically separate the input cables from those of the
power supply, outputs, and power connections.
- use braided and shielded cables, with sheathing grounded
at a single point.
2�3�3 Installation notes
- Moreover, the applications with solid-state units require a
safety automatic switch to section the load power line.
To ensure the high reliability of the device, it is necessary to
install it properly inside the panel so to obtain an adequate
thermal exchange. Fit the device vertically (maximum angle 10°
to the vertical axis) see figure 3
• Vertical distance between a device and the panel wall
>100mm
• Horizontal distance between a device and the panel wall at
last 10mm
• Vertical distance between a device and the next one at last
300mm.
• Horizontal distance between a device and the next one at last
10mm.
Check that the cable holder runners do not reduce these
distances, in this case fit the cantilever units opposite the panel

80993B_MHW_GFW-Xtra_06-2018_ENG
so that the air can flow vertically without any obstacles.
• dissipation of device thermal power with effects on installation
room temperature.
• thermal power dissipation with limits on installation room
temperature.
• requires exchange with external air or an air conditioner to
transfer dissipated power outside the panel.
• maximum limits of voltage and derived power of transients on
the line, for which the solid state power unit contains protective
devices (based on the model).
• presence of dispersion current in GFW in non-conducting
state (current of a few mA due to RC Snubber circuit to
protect).

damage to persons or property deriving from
tampering, from incorrect or improper use, or
from any use not conforming to the

upper rectangular cooling grilles (on the side opposite the fan).
This will clean the internal heat dissipater and the cooling fan.
IN CASE OF OVERHEAT ALARM
If periodic cleaning does not eliminate the problem, do as follows:
aRemove the fan support grille by detaching the two support tabs
bDisconnect the fan connector from the board
