PROFILE

The 3850T multifunction controller is
designed to control the temperature in
production processes (heat treatment,
kiln and autoclave management, etc.)
used in different industrial sectors such as
automotive, food, metalworks, etc.

The controllers consist of three elements:
the operator interface with touch screen
display and keys, the I/O module group for
connection to plants and machinery and the
connection cable between the interface and
the module group.

The color touch screen display 7” allows
the operator to easily and quickly interact
with the controller, managing actions and
parameters.
Access to the main controller functions and
navigation between pages is made easier
thanks to its 10 function keys, some of
which are customisable.
Customized pages may be configured
directly on the display, even without a PC
or external software. This option allows
you create optimised graphic interfaces
to control the machinery used. A graphic
symbol library is provided for this purpose
(buttons, bargraph, data display, etc.) that
can be set and linked to the controller
variables. You may also import images,
such as representations of the machinery

or of the system’s operating diagram, to
be used as a background, to make control
even more intuitive for operators.
The controller can manage up to 16 PID
loops, fully configurable. Each PID can be
used as a control for a single loop, a valve
or a ratio control, it can be connected to
the profile programmer or be used as a
cascade controller.
Tuning is performed through advanced
algorithms that ensure stable and accurate
temperature control, avoiding exceeding
set limits or having unstable process
control even in critical heat or fast motion
processes.

The setpoint profile programmer allows
you to set the programs to manage heat
treatment cycles. The profile is the set of
segments that describe the setpoint curve.
You can create up to to 250 programs,
stored internally, each of which can contain
up to 50 segments.
Each program lets you set up to four setpoint
profiles. A descriptive message, 16 input
events (IN), 16 outbound events (OUT), the
setpoint value and the HBB alarm threshold
can be set for each program.
You can launch up to 8 programs
simultaneously, each of which can handle
up to 4 synchronous profiles.
The profile programmer can be set in
synchronous mode (all profiles are run with

a common time base) or asynchronous
(each profile can be run with an independent
time base). The asynchronous mode is
obtained by running different programs
simultaneously.

The available logical operators (AND, OR,
Timer, Counter etc.) allow you to create
custom logic operating sequences with
the PID, thus obtaining complete and
flexible machine control.
The available settable mathematical
functions (addition, multiplication,
division, minimum or maximum value,
algorithms, etc.) can be used associated
with process values as analog channels
and virtual channels, to manage advanced
controls, such as ratio controls or custom
mathematical formulas.

The Data Logger function, combined
with the Real Time Clock (RTC clock with
rechargeable buffer battery) stores process
data, IN/OUT signals and the status of
the alarms in an open file (.CSV format) or
encrypted file. The minimum data sampling
frequency is 1 second. Saved files can then
be exported from the controller via USB or
Ethernet network.
The batch report option lets you to
associate this data with a specific batch
produced, to be able to use them in
production and quality reports.

A specific application for PC (Report
Utility) is available for easy management
of all data logger data and the production
batch reports which allows you to copy and
delete files via an Ethernet network between
the controller and a PC, manually by the
operator or automatically at configurable
time. The data stored on the PC can then
be displayed in graphical format or a
spreadsheet (Excel type) or exported as
CSV or PDF files.

For the quick and safe installation of
the machinery or plant, use the recipes
stored in the controller. The recipes, easily
retrievable by the operator, can be of two
types: OEM manufacturer recipes, which
contain the machine setup parameters and
production recipes, which contain single
production settings (profile program, logical
steps, math functions).
The recipes can be easily transferred
between different controllers via USB key
or Ethernet network.

Controllers offer complete diagnostics
(probe break down or incorrect connection,
total or partial load break down, control loop
faults), which helps the operator in case of

controlled machine or process faults.
All controller alarms are stored internally
and can be viewed as Active alarms and
Historical alarms. The relevant message is
displayed for each historical alarm with the
date and time of the various states (active
alarm, ACK, and alarm cleared). The ACK
parameter, settable for each alarm, ensures
that the active alarm was acknowledged by
the operator.
An internal energy counter, with
configurable offset alarm, provides energy
consumption and cost totals.

For accurate time stamps, the controller
supports the Simple Network Time Protocol
(SNTP) service, which continuously
updates the controller’s date and time from
the SNTP server connected via Ethernet
network.

The weekly clock function lets you
automatically start or stop a programmer
or a process, without the need of operator
intervention.
The clock is based on a settable weekly
calendar (day of week and time).

The display language selection lets the

operator interact with the device in the
preferred language, facilitating work.

Secure access to all controller parameters is
guaranteed by 3 preconfigured password
levels (Operator, Maintenance technician
and OEM manufacturer). In this way, each
user can only access the assigned functions
and parameters.

You can connect the controller to the factory
HMI/SCADA network by using standard
Modbus TCP (Ethernet) connectivity.

Complete controller configuration is
facilitated by use of the PC programming
tool GF_express, which proposes intuitive
Wizard pages, permitting easy construction
of customized graphic pages and advanced
logic.
