4...20 mA Electrical current used as a signal that is
transmitted by certain sensors or that is
specifically used to control a device such
as, for example, a motor-driven valve.
Alarm Output that is triggered when a certain
condition is met such as, for example, a
certain temperature.
Auto Tune Function that lets you easily calculate and
set P, I and D parameters thanks to con-
troller self-learning.
Batch Production batch ID.
Batch Report A series of analog and digital variables are
generally associated with the batch. The
report starts with the program RUN com-
mand and ends when the program END
status is reached.
Blocks Default controls for specifications
Function function used in Sequential Logics.
Cool Control used for cooling.
Data log
encryption Technology that guaranteed logged data
integrity (DataLog and Batch).
The saved file is read and write protected
by a CRC control. Encrypted files can be
decrypted by the DataLog Utility for PC.
Datalogger Continuous recording function for a series
of analog and digital variables.
GETLogic Gefran Embedded Technology: function
that lets you set Sequential Logics directly
from the terminal.
GETView Gefran Embedded Technology: function
that lets you set custom graphics pages
directly from the terminal.
HBB Alarm Hold Back Band: alarm associated
with the SP profile, that checks that the
reference variable (PV) remains within a
tolerance band set according to the gen-
erated SP. If PV goes outside the set band,
the profile generator will be shut down and
HBB WAIT will appear on the monitor. The
profile generator automatically returns to
RUN when PV returns within the tolerance
band. If you want to move forward with
profile steps in HBB condition, SKIP is
permitted, provided you first go to HOLD
STATUS.
HB Heater Break Alarm: requires use of cur-
rent transformer inputs, associated with a
control output, of which it takes into con-
sideration the ON and OFF phases. The
alarm signals changes in load absorption,
discriminating between current values for
current inputs.
Heat/Cool Control that is used both for heating and
cooling (requires two control outputs).
Heat Control used for heating.
Hysteresis When the value of the controlled variable,
at a precise moment, depends not only
from another reference variable, but also
by the values which the controlled variable
had previously, we are in the presence of
hysteresis. The hysteresis can therefore be
seen as an inertia which affects the control
system, causing variable delays between
variation of the reference variable and
variation of the controlled variable.
Sequential Logic Sequence of function blocks that describe
the sequential management of the ma-
chine cycle.
ON-OFF Control procedure based on output on and
off. In heating control, the output remains
active until PV is a certain amount less
than SV (offset), and then turns off until
PV is higher than SV by the same amount
(or different, depending on the controller
configuration). In the case of cooling, the
output it is on until PV > SV - offset and off
until PV < SV + offset. This type of control
is not intelligent, does not take account of
the disturbances and is not very accurate,
but ensures a limited number of output
switching.
Overshoot Situation where PV exceeds SP because
the control action was too late. The ON-
OFF controls have a greater overshoot
than the PID controls.
PID Acronym for Proportional-Integration-Dif-
ferentiation indicates a negative feedback

80703B_MHW_2850T/3850T_02-2019_ENG 7
PREFACE
system, meaning a device whose input
acquires a value from a process, compares
it with a reference value and uses the
difference (error) for determine the value
of the controller output variable, which is
the variable that controls the process itself.
The output is controlled according to the
actual error value (proportional action), a
set of previous error values (integral action)
and the error value rate of change (deriva-
tive action).
Setpoint Profile See SP.
Program
Function set (Sp Profile, Sequential Logic,
Recording) that describe a production cycle.
Pt100 Commonly used temperature probe.
At 0° C /F, its resistance is 100 ohms, while
at room temperature is about 106 ohms.
You can test the Pt100 for electrical con-
tinuity and you can use normal extension
cords.
PV Acronym for Process Value, which is the
value that the process variable (tem-
perature, valve opening, etc.) has at that
moment.
Solid State
Relay Also known as SSR (Solid-state relay) is
a relay designed specially for frequent
switching. There are no moving parts
or mechanical contacts, but may, however,
fail or short circuit. These types of relays
are often used in temperature control
systems such as PID.
Segment Basic element for the configuration of a
SP profile. It describes the operations of
an individual segment in detail. The set of
segments describes the execution of a SP
profile.
Sensor A device that translates physical phenom-
ena (i.e. resistance variation as a function
of temperature) in electrical signals that
can be acquired and processed by the
controller.
Setpoint Set value (see SV).
SSP SP/FSSPActive set point, in the case of a
set point gradient, shows its real value.
SP Acronym for Setpoint Profile meaning the
set of segments that describe the trend
over time of a value, typically a setpoint
and the status of a series of digital events
(In/Out).
SV Acronym for Set Value which is the value
that the process variable (temperature,
valve opening, etc.) must achieve and
maintain.
TA Current transformer
Thermocouple Sensor that transmits an electrical signal
of a few millivolts, that cannot be tested
for electrical continuity.
It needs specially designed extension
cords.
Undershoot Situation where PV does not reach SV
because the control action was too early.
The ON-OFF controls have an undershoot
greater than the PID controls.
Engineering unit Unit of measure suited to directly express
the measured physical variable value.
Control output Output that controls the process and is
turned on and off as needed.

1. GENERAL DESCRIPTION
80703B_MHW_2850T/3850T_02-2019_ENG
1. GENERAL DESCRIPTION
1.1. Profile
The 2850T and 3850T multi-purpose controllers designed
to control the temperature in production processes (heat
treatment, kiln and autoclave management, etc.) used in
different industrial sectors such as automotive, food, metal-
works, etc.
The controllers consist of three elements: the operator in-
terface with touch screen display and keys, the I/O module
group for connection to plants and machinery and the con-
nection cable between the interface and the module group.
The two controllers share the same main features and the
same functions. The differences are listed in paragraph
“1.2. Model differences” on page 10.
The color touch screen display (3.5" for the 2850T model
and 7" for the 3850T model) 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 function keys
(6 for model 2850T and 10 for model 3850T), some of which
are customisable.
Customized pages may be configured directly on the dis-
play, even without a PC or external software. This option al-
lows 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 back-
ground, to make control even more intuitive for operators.
Controllers can control different PID (up to 8 for model
2850T and up to 16 for model 3850T) 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 pro-
grammer 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 200 (model 2850T) or 250 (model 3850T)
programs, stored internally, each of which can contain up to
50 segments.
Each program lets you set up to four setpoint profiles. A de-
scriptive 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 four programs simultaneously with
the 2850T model and 8 programs simultaneously with the
3850T model, each of which can handle up to 4 synchro-
nous profiles.
The profile programmer can be set in synchronous mode
(all profiles are run with a common time base) or asynchro-
nous (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 sequenc-
es integrated with , thus obtaining complete and flexible
machine control.
The available settable mathematical functions (addition,
multiplication, division, minimum or maximum value, algo-
rithms, 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.

1. GENERAL DESCRIPTION
80703B_MHW_2850T/3850T_02-2019_ENG
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 mini-
mum 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 produc-
tion batch reports which allows you to manually copy and
delete files via an Ethernet network between the controller
and a PC or automatically at dates that can be set manually
by the operator. 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 con-
tinuously 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 oper-
ator 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) con-
nectivity.
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.
