For temperature values:
•
Exclusive continuous temperature measurement of
all power terminals with an alarm for loose terminal
diagnosis.
•
Continuous monitoring of the internal temperature of
the power module with automatic disconnection and
an alarm signal in the event of over-temperature.
•
Fan output temperature measurement for electrical
panel cooling system efficiency diagnostics.
•
Insufficient fan power alarm.
The GF_eXpress configuration software also offers an
extensive list of additional diagnostic conditions, such as
alarm status storage, for immediate and easy analysis in the
event of a fault.
1.1.4.
Configuration
The GPC controllers have been designed with various
configuration levels to make initial start-up operations as
simple and intuitive as possible.
The GF_eXpress configuration software (freely download-
able from the Gefran site www.gefran.com) has a "Smart
Configuration" procedure to configure the controller through
a few targeted questions, with limited need for knowledge
of the parameters and their meanings. At the end of the
procedure (average duration 5 minutes) the controller is
ready to pilot the load.
Another section of the software contains the "Wizard" pag-
es, showing the main parameters divided into topics, with a
part of the parameter monitoring always active.
With GF_eXpress, you can create and save entire param-
eter recipes and easily duplicate them on other devices.
Parameters can also be monitored and displayed graphical-
ly with the oscilloscope function.

Field of use
As the Advanced Power Controller can be used in a multi-
tude of installations and environments, adequate technical
training is required to make full use of the instrument's
potential.
In any event, the instrument must always be used within the
limits indicated in the technical specifications in the accom-
panying documentation.
Regardless of any other consideration, it is always strictly
forbidden to:
•
use the instrument or parts of it (including software) for
purposes other than those intended in the accompany-
ing technical documentation;
1.3.
Technicians and operators
The Advanced Power Controller must only be used by per-
sonnel qualified for their assigned task, in compliance with
the instructions for the task, particularly the relevant safety
warnings and precautions.
Qualified personnel, due to their training and experience,
are able to recognise the risks involved in use of the instru-
ment and avoid potential hazards.

The GPC controllers can be equipped with a GFW/GPC-OP
portable programming terminal, powered by the controller,
which permits monitoring of process variables and changes
of configurations, if necessary, via password.
1.1.5.
Fieldbus
A Modbus RTU port is always available for connections
with the configuration tool or with HMI or PLC devices
equipped with Modbus Master communication.
An extensive range of certified Fieldbus options lets you
add GPC controllers to control architectures with the most
popular PLC brands, allowing you to access any device
variable with standardised configuration files.
These controls can be combined with softstart ramp
functions, with options such as "current limit" to manage
current peaks at switch-on and the RMS current value at
steady state, thus optimising consumption and increasing
the operating life of the load.
1.1.6.
More
The availability of phase angle (PA) control (the only control
method that completely eliminates flickering in IR lamps),
combined with current limit and current, voltage or load
power feedback functions, means that "critical" applica-
tions such as Super-Kanthal™ special heating elements, sil-
icon carbide resistors or single and three phase transformer
primaries can be resolved with confidence.
•
modify working parameters not accessible to the
operator, or decrypt or transfer the software or any of
its parts;
•
use the instrument in particularly flammable environ-
ments;
•
repair or modify the instrument using non-original spare
parts;
•
use the instrument or its parts without having read and
correctly interpreted the contents of the accompanying
technical documentation;
•
dispose of or discard the instrument in common land-
fills.
In addition, it is assumed that the technicians who commis-
sion the instrument and connect it to other units, and those
in charge of maintenance, have adequate technical knowl-
edge, particularly in the field of electronics and automation,
to fully understand the information provided in this manual.
