PREFACE
Typical concepts used in the manual
Pay attention when the following symbols are found in the manual.
They indicate particularly important information
that effect correct product operations or safety, or
provide mandatory instructions.
They indicate a risk condition for the installation
technician or user due to hazardous voltages.
They call the reader's attention to a specific point.
Glossary
They signal a suggestion that could be helpful for
better device use.
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 controller 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 command 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 generated 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 consideration 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.

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

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 (derivative action).

1. GENERAL DESCRIPTION
1. GENERAL DESCRIPTION
2850T 3850T
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, 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 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 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.
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 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 four programs simultaneously with
the 2850T model and 8 programs simultaneously with the
3850T model, 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 integrated with , 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.

1. GENERAL DESCRIPTION
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 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 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) 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.

Warning! The installation of the devices described in the manual must be carried out by qualified personnel, following the laws and regulations and in accordance with the instructions contained in this manual.
Before proceeding with the installation, check that the controller is intact and has not been damaged during transport. Also make sure that the package contains all the accessories listed in the supplied documentation, especially
the sealing gasket and fixing brackets.
Verify that the order code corresponds to the configuration required for the application in which the controller is
intended (the supply voltage, number and type of inputs and outputs). See chapter 10 - Order codes - to verify the
configuration corresponding to each order code.
Warning! If even one of the above-mentioned requirements (qualified technician, device intact, configuration not
matching that required) is not met, suspend installation and contact your Gefran dealer or Gefran Customer Service.
2.1. Controller assembly
2. INSTALLATION
2. INSTALLATION
2.1.1. General installation rules
The controller is designed for permanent indoor installations. It must be mounted in electrical cabinets, or in
machine or production process plant control panels, which
are able to protect the connectors on the back of the controllers.
Warning! The controller must NOT be installed in
dangerous environments (flammable or explosive).
It can be connected to elements that operate in
such environments only by means of suitable
types of interfaces in conformity with the applicable safety standards.
Warning! If the controller is used in applications
with risk of damage to persons or property, it is
essential to combine it with specific alarm devices. We recommend including the ability to check
alarm operation even during the normal operation
of the controller and the system or equipment
being monitored.
Sudden changes in temperature, freezing or condensation
or corrosive gases should not occur where the controller is
installed.
The controller can operate in environments with pollution
degree 2 (presence of non-conductive dust, only temporarily conductive due to potential condensation). Prevent the
device from being reached by metallic processing particles
or scraps as well as any condensation products.
The controller is sensitive to strong electromagnetic fields.
Avoid placing it near radio devices or other equipment that
can generate electromagnetic fields, such as high-power remote controllers, contactors, relays, thyristor power
groups (in particular, phase shift), motors, solenoids, transformers, high-frequency welders, etc.
2.1.2. Drilling Dimensions
For proper interface installation, respect the size of the single hole and the spacing between the adjacent holes shown
in the illustrations of the different models (“Figure 2 - 2850T
interface dimensions and drilling templates” on page 13
and “Figure 4 - 3850T interface dimensions and drilling
templates” on page 15).
Warning! The support on which the interface must
be mounted must have the following characteristics:
• be rigid and sturdy enough to support the
device and not bend during use;
• have a thickness between 1 and 4 mm, in
order to allow the device to be secured with
the supplied brackets.
2.1.3. Protection against dust and water
infiltration
The front of the interface provides IP65 protection. Therefore, the device can be installed in dusty environments or
subject to water sprays provided that:
• the compartment containing the interface is also dust
and water-tight;
• the support on which the interface is installed is perfectly smooth and without undulations in the front;
• the hole on the support scrupulously complies with the
indicated drilling dimensions;
• the interface well-secured to the support, to enable
the gasket inserted between the device and panel to
ensure water-tightness.
Warning! If not adequately protected, the interface protection degree is IP20 (rear housing and
connectors).
80703B_MHW_2850T/3850T_02-2019_ENG

2. INSTALLATION
2.1.4. Vibration
The interface can withstand vibrations from 10 to 150 Hz,
20 m/s2 (2 g), in all directions (X, Y and Z).
If the device is mounted on a support that exceeds these
limits, a vibration suspension and damping system should
be provided.
2.1.5. Minimum clearances for ventilation
The temperature of the compartment that contains the
interface should not exceed, in any case, the 55° C (131 °F).
Never block the air vents.
The illustrations “Figure 2 - 2850T interface dimensions
and drilling templates” on page 13 and “Figure 4 - 3850T
interface dimensions and drilling templates” on page 15
indicate the minimum distances to be observed to ensure
device ventilation.
Tip. The lower the temperature in which the device
operates, the higher the life expectancy of its electronic components.
2.1.6. Positioning
The interface must be positioned so that the display is not
directly illuminated by the sun or by particularly intense light
sources. If necessary, shield direct beams, for example,
with an anti-reflective screen.
The interface angle should be between 30° and 120°, as
indicated in the figure.
4. Tighten the screws to lock the device to the panel. The
tightening torque must be between 0.3 and 0.4 N m.
The following illustrations show how to secure the two
interface models.

2.2. Installing I/O modules and Gefran communication
2.2.1. General installation rules
2. INSTALLATION
The I/O module groups are designed for permanent indoor
installations. They must be installed in control panels that
are able to protect the connectors on the modules.
Warning! The modules must NOT be installed in
dangerous environments (flammable or explosive).
They can be connected to elements that operate
in such environments only by means of suitable
types of interfaces in conformity with the applicable safety standards.
Sudden changes in temperature, freezing or condensation
or corrosive gases should not occur where modules are
installed.
Modules can operate in environments with pollution degree
2 (presence of non-conductive dust, only temporarily
conductive due to potential condensation). Prevent modules from being reached by metallic processing particles or
scraps as well as any condensation products.
2.2.2. Vibration
The modules can withstand vibrations from 10 to 150 Hz,
20m/s2 (2 g), in all directions (X, Y and Z).
If the modules are mounted on a support that exceeds
these limits, a vibration suspension and damping system
should be provided.

2.2.5. Module installation
The modules must be mounted on metallic and grounded
DIN 35 mm (1,38”) rail inside switchboards.
To secure the modules:
1. insert the top of the module hook on the DIN rail;
2. rotate the module to the vertical position, pressing until
you hear the "clack" which indicates that the lower
slide hook is attached to the DIN rail.
2.2.3. Minimum clearances for ventilation
The temperature of the compartment that contains the
modules should not exceed, in any case, the 55° C (131 °F).
Never block the air vents.
Tip. The lower the temperature in which the modules operate, the higher the life expectancy of their
electronic components.
Warning! Forced module cooling (i.e. with a fan)
can cause measurement errors.
2.2.4. Positioning
The modules can only be mounted horizontally.
When positioning the modules, make sure that there is
sufficient air circulation around them. Figure 9 shows the
minimum distances from adjacent walls that must be respected for ventilation.
Warning! There is a spring contact at the back
of each module to ground it through the DIN rail.
There will be no electric continuity with the ground
if the rail is not conductive or is not connected.

2.2.6. Removing Modules
To remove the modules:
1. pull down lower slide lock to release the module;
2. rotate the module outwards;
3. remove the top part of the module hook from the DIN
rail.

2.3. Connections
Warning! Please remember that failing to follow
the instructions below could lead to electrical safety and electromagnetic compatibility problems, as
well as void the warranty.
2.3.1. General rules for connections
1. The externally connected circuits must have double
insulation.
2. In the case of shielded cables, the shield must be
grounded at one point only, possibly close to the I/O
module group.
3. Input cables must be physically separated from output
ones and the power connections.
4. Do not connect the unused I/O contacts.
2.3.2. Electromagnetic Compatibility (EMC)
The most stringent generic standards were used for electromagnetic compliance, using the following experimental
configuration:
Connection Cable section Length
Voltage 1 mm
Serial port 0,35 mm
Thermocouple 0,8 mm

2.3.3. Cables
Always make connections using cables suited to the voltage and current limits specified in the Technical Specifications.
For connections, use copper wires with insulation for
60/75° C (140/167 °F). For non power connections, do not
use twisted and shielded cables.
Warning! Anchor cables, at least in pairs, so that
the mechanical stresses do not discharge on the
terminal block connections.
2.3.4. Voltage
Warning! Before powering the interface and I/O
module group, make sure that the supply voltage
corresponds to that on the device plates.
The 24 VDC supply must come from a Class II source or
limited energy low voltage. The power supply must use
a separate line from that used for the electromechanical
power devices and low-voltage power cables must follow a
separate path from the plant or machine power cables.
Warning! Make sure that the grounding connection is efficient. A missing or ineffective ground
connection can cause unstable device operations
due to excessive environmental disturbances. In
particular, check that:
• the voltage between ground and earth is < 1 V;
• the ohmic resistance is < 6 Ω.
22
80703B_MHW_2850T/3850T_02-2019_ENG
Ensure that the 24 VDC power supply is fitted with a switch,
or that there is a bipolar switch on the line that connects it
to the mains voltage, in order to easily cut-off power to the
controller in case of need.
2.3.5. Input and output connections
The I/O module input and output lines should be separated
from the power line.
To avoid disturbances, the I/O module input and output
cables must be kept away from the power cables (high
voltage or large current).
Input, output and power cables must not be laid in parallel.
Shielded cable or separate cable ducts are recommended.
Warning! If the controller is connected to NON
isolated electrical devices (i.e. thermocouples), the
ground connection must be made with a specific
conductor to prevent it from being directly through
the machine structure.
The connectors are polarised and accept wires of between
0.2 and 1,5 mm2 (from 24 to 15 AWG).
Insert the wire in the connector hole corresponding to the
terminal that is to be connected. After inserting the conductors, push the connector into the module.
To disconnect a wire, place a screwdriver into the slot next
to the conductor, to release the retaining spring.
The following figure shows how to insert or remove a wire
to/from the connector.

2.5. Ethernet Connections
Personal computers, servers and multi-purpose controllers
can communicate through the Ethernet connection. This
means that you can:
• control one or more multi-purpose controllers through
one or more personal computers;
• store data produced or used by one or more multi-purpose controllers on one or more servers and have them
readily available;
• keep one or more multi-purpose controllers time
synced via an NTP (Network Time Protocol).
1. Power supply 24 VDC ±25% Also connect the connector to the ground wire.
2. CAN Port DB9 M.
3. Green LED indicates active Ethernet connection.
4. RJ45 Ethernet port 10/100 Mbit/s.
5. Yellow LED indicates data transfer in progress.
6. USB port type A.
NTP servers allow computer systems to be synchronised,
meaning all connected devices will have the same time, referring to a precise external clock and not only the internal
clock, less precise.
Synchronisation enables a value offset of less than one
millisecond for systems belonging to the same network and
in any case less than a few hundred milliseconds for remote
networks.

2.5.1. Private networks and public networks
The connection networks may be private or public.
A private network is a closed network with no connections
to the outside world and is intrinsically more secure.
The public network (Internet), in contrast, allows you to access the devices connected to the network from anywhere
in the world but, because of this, it is less secure.
Finally, there is the option of connecting a private network
to a public network through a device called a firewall, which
keeps them isolated except for duly authorised traffic.
In this type of configuration, a private network is often identified with the acronym LAN (Local Area Network) and the
public with the acronym WAN (Wide Area Network). Other
ways to identify them are intranet and extranet.
Note that the private network can also be constituted by a
single device.
Figure 13 3 shows the different types of networks.

Figure 13 - Types of networks
2.5.2. Firewall
The firewall is a physical device or a software application
that isolates a device or a network section from the rest of
the connection network.
Several firewalls may need to be crossed to reach a device.
For example, there might be a firewall between the corporate LAN and the Internet and another firewall that isolates
the device from the corporate network.
To access a multi-purpose controller behind a firewall you
need to configure the access channels or firewall traffic
rules and implement connections via VPN (Virtual Private
Network) or directly through a modem.
Consult the corporate IT system administrator to properly
configure firewalls or know the parameters to implement a
VPN or connect via modem.
In order to connect to an external multi-purpose controller
and ensure the proper operations of all the services, the
following ports need to be open (communicate the list to
the IT administrator):
Port Service
20, 21 FTP
502 Modbus TCP
5500, 5800, 5900 VNC
2.5.3. Router
In cases of particularly complex or extended Ethernet networks or that are subject to intense broadcast type traffic,
the connection to the 2850T and 3850T controllers must
be isolated. This is achieved by structuring the network
into subnets (corporate/machine), or by limiting the TCP/IP
traffic actually necessary for hubs or services.
This rule, in general, should be also be observed when
connecting 2850T and 3850T controllers in small sized
networks or with remote access systems.
The recommended solution is to connect the 2850T and
3850T controllers via a router.
The router is a layer 3 device that allows you to route the
communication packets between different networks, meaning to determine specific port outputs package that arrived
based on the target IP address.
The use of router ensures that the Ethernet traffic to or from
the 2850T and 3850T controllers is filtered and remains
isolated from the rest of the corporate network or from the
external network.
2.5.4. VNC (Virtual Network Computing)
You can check the multi-purpose controller remotely using
a VNC connection with a personal computer. The RFB protocol used is public domain.
With the VNC connection, the multi-purpose controller
assumes the host function and the personal computer the
client, where the connected multi-purpose controller interface is exactly reproduced.
Every action (clicking with the mouse, settings, etc.) performed on the reproduction of the interface display that
appears on the personal computer is faithfully replicated on
the controller and vice versa. The pages on the display and
computer monitor are synchronised in real time.
2.5.5. VNC Server
The VNC server is part of multi-purpose controller operations. The VNC server is disabled by default. To enable it:
1. Log in as administrator. For more information on the
login procedure, refer to the section “4.1. Login password” on page 35.
2. Open the Home Page by pressing the
selectService.
3. Select Setup
4. Select Configuration on the page that opens. Note the
device IP address that is used to configure access
through clients. If the network addresses have not yet
been set, see paragraph “4.14.2.2. Network Configuration” on page 72.
5. Select Network.
6. Select NTP VCN Configuration.

4. MENU AND CONFIGURATION
4. CONFIGURATION
A high level of knowledge of problems and techniques associated with the controlled process is required to properly
set the parameters needed to configure the controller so
that it meets the application requirements.
If you are unsure of your skills, or you are not fully aware of
the consequences that could result from incorrect parameter settings, we do not recommend you proceed with the
configuration.
4.1. Login password
Access to the menus is protected by 3 password levels:
Operator, Maintenance and OEM, listed from the one with
lowest privileges to that with full access to all controller
functions and parameters.
The level determines which menus, with their functions and
parameters, you can navigate.
The first level (level 0), Operator, provides access to submenus and more operational parameters, namely the ones
that most affect the daily monitored machine or plant
operations.
The second level (level 1), Maintenance, provides access to
the sub-menus and the parameters dedicated to the configuration of device hardware resources.
Warning! Before commissioning the controller the
user must ensure the parameters are set correctly
to avoid damage to persons or property.
The default password values are:
• Level 0: free access (no user or password)
• Level 1: User = service, Password = 5678
• Level 2: User = admin, Password = 1234
Authentication with password level 0 has no time limit,
authentication with level 1 and 2 passwords expire after 30
minutes.
The name of the person currently logged in may be read in
the lower right hand corner of the display.
Passwords can be created and modified. See the paragraph in this regard “4.15.6. USER CFG sub-menu” on
page 90.
The third level (level 2), OEM, is reserved to the manufacturer who has included the multi-purpose controller in its
machinery or plant.
4.2. Display, configuration and management
Specific menus are used to view information on the
multi-purpose controller and operations it performs, to configure the device and its functions and, ultimately, to manage the machine or process controlled by the controller.
Each controller parameter, function or process can be managed by one or more menus.
Available trees and menu items vary depending on the controller model. The individual display or configuration pages,
however, are the same for all models.
The menu structure shown in detail is that of the controller
complete with all the options.
For other versions, refer to the graphical representations of
the different menus (paragraphs “4.7. Controller menu with
GETLogic and GETview options” on page 40, “4.8. Tool
menu with GETLogic, GETview and recorder options” on
page 41 and “4.9. Controller menu with GETLogic, GETview and recorder options” on page 42), from which you
can trace back to the individual information and configuration pages available.

4. CONFIGURATION
4.3. Monitor Program
The Monitor Program page is the page that shows the most
important information of the loaded program. It is also the
page which, by default (editable), appears at the end of the
multi-purpose controller start-up procedure. Through this
page, you can also manage the program (start, stop, etc).

1. Viewing the signal to run the program.
2. START button: starts the program. A pop-up window opens when you touch the button displaying the
production batch number and you can enter a name.
To enter this information, touch the appropriate fields
and use the virtual keyboard that appears. The data is
not mandatory, but entered in the report produced at
the end of processing, if the batch name is not specified, it will be given the same name as the previous
one. Touch the Start button in the pop-up to start the
program or the Cancel button to cancel the operation
and close the pop-up.
3. RESET button: stops the program and returns to the
Ready state (first step of the program), skipping any
steps yet to be run. This opens a pop-up confirmation
window. Touch the End button in the pop-up to stop
the program or the Cancel button to cancel the operation and close the pop-up
4. PAUSE button: freezes the program, which assumes
the Hold condition. To resume the program from the
same point where it was stopped, touch the START
button again (If necessary, you may go on to the next
step in the HBB status using the HOLD and SKIP
commands).
5. SKIP button: allows you to skip to the next step and is
only active when the program is in the Hold condition.
6. Program status (Ready; Run; Hold; End).
7. Program run time. The progress bar indicates its progress in relation to the total theoretical time calculated.
8. Time remaining to run the step.The progress bar
indicates its progress in relation to the theoretical time
calculated.
9. Program messages:
• wait condition: the program is suspended pending
the signal to run the step;
• suspend: the program was suspended;
• hbb ch n: the program was suspended because
the PV is out of the HBB control range.
10. Number of the segment in progress.
11. Name of the program viewed. Touch the field to open
a list of stored programs from which you can select the
program to use.
12. Selecting PID associated with the program.
13. Deviation bar graph: indicates, in percentage, the
difference between PV and SP. If PV is less than SP the
bar is lit in blue to the left of the median point, if PV is
greater than SP is lit in red to the right of the median
point.
14. Process Value (PV): the value that the process variable
has at that time. The variable unit of measurement is
also shown.
15. Setpoint (SP): is the process set value, which is the
value that the machinery or system must reach and/or
maintain.
16. PID identification number.

4.4. Monitor Recorder
If the programmer option does not appear, the instrument
has a number of record pages. These pages may be used
to manage record recipes (start up, stop, etc).
The Monitor Program page is always accessible:
• using the Home Page Monitor Monitor Prog
menu or more simply
4. CONFIGURATION
The procedure for control recipe settings is very similar to
that of the programmer, with the same pages and the same
settings. The reader is therefore referred to the explanation
appearing at “4.13.3.4. Program report configuration” on
page 69.
• by touching the
in the lower left hand corner of the display
There are three different views, showing one, two or four
records at the same time, respectively. For each record, you
may:
• start with the START button
• stop with the STOP button
• assign a name to the record, which will then appear in
the “batch name” field
• view progressive record time

4. CONFIGURATION
Warning! The DO field shows information on each
single digital output, while the PID field shows
totals for all outputs used during the PID.
The two calculations are independent. If the energy consumption parameter of a DO (already used by the PID) is set, the total energy count will consider that of the DO twice.
The DO energy section allows you to add the power of the
load managed for each output.
To view the outputs of the various modules ( F-MIX and
R-EU16), use the + button.
To enter the power, touch the field next to the output number and enter its value.
The data will be used for Synoptic section views.
ENERGY CALCULATION WITH TA
Energy is calculated on the basis of the current reading
obtained from the TAs connected to the PID in question.
The voltage to be entered is the supply line RMS voltage.
So if it is single-phase, set 230V, or if it is three-phase, set
400V (in Europe).
To associate CT input to the PID, refer to the configuration
page of the HB alarms, paragraph “4.15.4.8. PID HB alarm
configuration” on page 86
If the load is single-phase (there must be only one CT set
for each PID), multiply the rms current value supplied by the
TAs by the concatenated (line) voltage.
If it is three-phase (with 2 TAs set per PID), multiple the
average of the two rms current values supplied by the 2 TAs
by the set voltage, by the square root of three.
P=V*(IrmsTA1+IrmsTA2)/2)*sqrt(3).
In both cases, the value thus obtained is multiplied by the
percentage of power supplied by the PID in question and
operates independently of the DO outputs.
IMPORTANT: in this assumption, the calculation is reliable
only for actuators using zero crossing.
The active power calculated is in any case an approximation, in that we suppose:
- that the load is totally resistive (cosfi approximately one)
and balanced.
- that the grid is symmetrical and supplies an effective value
that remains constant over time.
For each of the 16 PID, the PID energy section lets you add:
• PID heating power (Heat);
• the supply voltage (Voltage), which allows for a more
precise calculation of power (power = current x voltage);
• PID cooling power (Cool);
To enter power and voltage, touch its field next to the PID
number and enter its value.
The data will be used for Synoptic section Monitor.
NOTES
- If a cascade PID occupies PIDs n and n+1, the energy
parameter setup will be set ONLY on PID n+1.
- Power may be counted in two ways for the hot PID (setting rated power or using TAs) and one way for the cold one
(setting rated power).

4.12.1. The Datalog
The Datalog is the recording function of the values assumed by a series of user-selected variables. The frequency with which these values are read (sampling) is always
determined by the user.
4.12.1.1. Archive Mode
The recorded data storage method depends on the instrument configuration:
• Model without SD Card option: data is stored directly
on the internal disk.
• Model with SD Card option: the log data for batch
reports and Data Logger are saved on SD Card and
optionally on internal disk.
With the model without the SD Card option you can:
• Copy or move the log files from the internal disk to
USB key.
• Copy or move the log files from the internal disk to
your PC using the DataLog Utility application.
• Delete the log files from the internal disk.
With the model with the SD Card option you can:
• Copy or move the log files from SD card to a USB key.
• Copy or move the log files from the internal disk to
USB key.
• Delete log files from SD Card.
• Delete the log files from the internal disk.
• Copy or move the log files from SD Card to your PC
using the DataLog Utility application.
• Copy or move the log files from the internal disk to
your PC using the DataLog Utility application.
4.12.1.2. File compression on the local disk
Log files stored in the local disk are automatically compressed to optimise occupied space. When moved from the
local disk to another external media (USB, SD or PC), files
are automatically decompressed, recovering their true size.
The compression factor for the local disk is about 4:1 (a 1
MB file becomes about 250 kB).
4.12.1.3. Amount of savable sampled data
The amount of sampled data that can be stored depends on:
• capacity of the storage medium;
• number of variables sampled;
• sample frequency;
• saved graphic imagers;
The table shows an estimate of the number of samples and
the overall sampling duration for the different instrument
configurations.
4.12.1.4. Out of memory alarms
To avoid losing data when the memory is full, the instrument
generates two types of alerts.
Warning Signal
Automatic alert in a pop-up window when the amount of
free memory, on the internal disk or SD Card, is less than
10 MB. The pop-up is displayed automatically every 10
minutes as long as free memory is less than 10 MB. There
is a button in the pop-up window to directly open the management page where you can delete the log files or move
them to a USB key.

4.13.1. What is a Program
A program consists of 3 macro functions to manage a production batch in its entirety.
The 3 macro functions are:
1. Setpoint profile generator.
2. Control logic (GETLogic).
3. Batch reports.
A setpoint profile is a set of segments, each characterised
by several parameters, which allow you to adjust the value
of a process or a device as a function of elapsed time, of
specific conditions and reference values stored in the controller or that are supplied from the outside.
In its most basic form, a segment consists of one step. It is
possible to create profiles made of segments with a double
step, which are shown in the graphics as two separate
lines. In this case, we have:
• a ramp, meaning a variation in a more or less long time
of the setpoint value;
• an optional permanence, meaning a period of time
in which the process value, after having equalled the
setpoint value, is kept constant.

The BASE table - synoptic outputs shows how the outputs
behave in the various modes.
Program Base configuration page (2) lets you configure, for
the 4 available profiles, the variables where the generated
values are written.
The parameters to be configured are:
• OUT: program setpoint variable.
• PV: variable used to control the HBB alarm and band
alarms.
• PID: PID identification number. The number appears on
the Monitor program page as the index of the displayed information.The PIDs controlled are exclusive
in terms of programmes in execution, so it will not be
possible to start programmes with resources already in
use. To free the resource, enter the value 0 in this field.
The number of rows filled out determines the number of
synchronised profiles enabled.
To define a variable for OUT or PV touch the line and select
the variable from the pop-up list that opens. For details on
the pop-up window, see the description on page 103.
Program Base configuration page (3) allows you to configure up to 16 input events to be used as consent to run the
segment to which they are associated.
To associate an input event with a digital resource, touch
the line and select the variable from the pop-up list that
opens. For details on the pop-up window, see the description on page 103.
Resources 1 to 8 may be set, among the consensuses
required for each segment, only by level 2

4. CONFIGURATION
Program Base configuration page (4) allows you to configure up to 16 output events that can be enabled (ON) or
disabled (OFF) in the various steps.
Output events can take the ON or OFF status or maintain
the previous state and can be associated with any segment
of the program.
To associate an output event with a digital resource, touch
the line and select the variable from the pop-up list that
opens. For details on the pop-up window, see the description on page 103.
Resources 1 to 8 may be set, among the outputs managed
for each segment, only by a level 2 user (admin or manufacturer), while resources 9 to 16 may be set by any user.
To define a variable, touch the line and select the variable
from the pop-up list that opens. For details on the pop-up
window, see the description on page 103.
4.13.3.2. Configuring the Program Segments
The Segments page let you configure each segment of the
program.
Each program can handle up to 4 synchronous profiles, i.e.
profiles that use the same time base for segment change.
Segments can belong to groups of contiguous segments
that can be repeated.
Page (5) of Basic program configuration
permits addition of variables to the recipe and memorisation of their values. These values are updated whenever
a change is made when the programme is loaded in the
memory.
When the programme is loaded, the “Recipe“ variables are
reinitialised with the values they had at the time of the latest
change with the programme loaded in memory.
These auxiliary variables may be used, for example, in GETlogic, to initialise counters or default values.
You may, for example, use a “counter” user variable which
is incremented by logic in the “Prog1” programme at every
external impulse. When working with the “Prog1” programme, the counter will reach the value 50 and it will be
memorised in “Prog1”. The programme is then removed
from memory, and the variable counter may be changed to
80 by any other logic.
When Prog1 is called up in memory in the future, the variable counter will be written to the value 50.
The variables used are retentive.
Use of variables that frequently change their value while the
programme is loaded in memory is not recommended.

A blank line appears in the window for the new segment.
Touch the individual fields to:
• Give a descriptive name to the segment. The name
can be an alphanumeric text up to 16 characters long.
• Assign a value to SP 1, the setpoint of the 1st synchronised profile.
• Assign a value to SP 2, the setpoint of the 2nd synchronised profile, if it exists.
• Assign a value to SP 3, the setpoint of the 3rd synchronised profile, if it exists.
• Assign a value to SP 4, the setpoint of the 4th synchronised profile, if it exists.
The step number is generated automatically.
Touch IO step in the pop-up menu to open Input Event
Configuration Window 1 that enables the segment to run.
The list corresponds to the corresponding variables set in
the Base section.
For each variable you can set:
• = : keep the original variable value.
• ON: assign value ON to the variable.
• OFF: assign value OFF to the variable.
To change the reference value, touch the field next to the
variable name repeatedly until the desired value appears.
Touch the CFG step button in the pop-up menu to open the
profile configuration window of the individual segments.
CH1, CH2, CH3 and CH4 correspond to synchronous profiles 1, 2, 3 and 4 respectively (the number of synchronous
profiles depends on the settings in Base section page 2).
For each variable you can set:
• - : ignore the variable value.
• ON: only run the segment if the variable is ON.
• OFF: only run the segment if the variable is OFF.
To change the reference value, touch the field next to the
variable name repeatedly until the desired value appears.
If the start conditions are not met, the program remains in
standby (WAIT CONDITION).
You can switch from one segment to another using the +
and - buttons above and below the segment number to the
left of the page. You can also jump directly to a particular
segment by touching its number and entering, in the virtual
keyboard that appears, the desired segment number.

As a segment run time, you can set a time (unique value
valid for all synchronous profiles), a gradient (value that may
be different for each synchronous profile), or both.
There are two times (ramp and retention) in the case of a
program with a double step, as shown in the figure ABOVE
(add number)
The configuration of the single profile can therefore be:
• Time = 0 and Grad ≠ 0: the SP setpoint for the profile is
generated following the gradient value set.
• Time ≠ 0 and Grad = 0: the SP setpoint for the profile
is generated following the set time.
• Time ≠ 0 and Grad ≠ 0: the SP setpoint for the profile
is generated based on the gradient but also takes into
account the set time, as shown below.
Segment behaviour with Time ≠ 0 and Grad ≠ 0
Case 1 - Segment time = Grad.
The set gradient reaches the segment SP setpoint in the
set time. The segment change occurs at the end of the set
time.

The increase or decrease ramp is linear. Starting from
the process value (PV) at the start of the segment, the
controller increments or decreases the setpoint value

corresponds to the final SP value.

• HBBl: Low range value for HBB alarm
• ALLh: Generic high temperature alarm value

• ALLl: Generic low temperature alarm value
• Group: PID group used for the segment.
HBB and ALL are two relative signals following the
OUT in the programme. They differ in that HBB stops
the programme cycle under way, while ALL is a generic
indication linked with the programme.

Report (Page 1) allows you to configure the DataLog by
determining the information to be stored.
The available parameters are:
• Sampling time: determines the sampling frequency.
The time interval between one sampling and the next
can vary from 1 to 3600 seconds.
• Include recipes: includes the program recipe at the
top of the DataLog.
• File name job no.: includes the production batch number in the file name.
• Encrypted file: apply encryption to the DataLog file.
The file can be decrypted with the DataLog Utility
application.
• Comma : dot format: use the dot as the separation
between the integer and the decimal part of the numbers.

4. CONFIGURATION
Special programmes, the ZERO programme
The ZERO programme is a special programme always
present in the instrument, a routine without any associated
profiles, but only the getLogic and Reporting part, which
cannot be deleted by the user. Its most important features
are:
• Continuous execution: the ZERO programme is
executed by default, with no need for the user to start
it, but it must be explicitly stopped. It follows from this
feature that the associated logical functions and report
will always be active.
• The logical functions of the ZERO programme: The
logical functions of the ZERO programme, unlike those
of all the other programmes, are editable while the
programme is under way. These functions should be
used for all system logic not strictly associated with a
single programme. For example, the logic of the ZERO
programme may be used to manage alarm chains.
• Continuous datalog: The ZERO programme generates
a continuous report which has all the features we have
seen in the section on reports, such as sampling time
and encrypting, but with some differences. As it is a
continuous record, the most important of these is the
possibility of breaking up the report file hourly, daily
or weekly. These files can only be viewed using the
ReportUtility tool. Another difference is the absence of
a recipe for association with the report file, because the
ZERO programme has no recipes.

Each clock acts on the “virtual functions” alarm_clkn_cmd1
and alarm_clkn_cmd2, where n is the selected clock number, from 1 to 4:
The PROGRAM CLOCK sub-menu allows you to create and
manage weekly clocks to automatically turn the controller
on and off.
Each clock operates on two "virtual functions":
• alarm_clkn_cmd1 to turn on and
• alarm_clkn_cmd2 to turn off,
where n is the selected clock number.
These functions can be used in logical functions to start a
program or to perform any other action, such as commanding a siren, raising or lowering a digital output, etc.The two
variables remain high for one second from time on which
they were set, to permit interception.
For each day of the week you can set a power-on and oneoff time. The time is entered as hour and minute; the time is
24 hour format.
Power off can be before power on. Switching on and off
can also take place on different days, meaning you can
turn on the controller and leave it on for a few days before
turning it off.
You can enable multiple weekly clocks at the same time.

4. CONFIGURATION
The page configuration sequence is specifically in reverse
order because the Base/Alarm/Variable/Synoptic order
reflects the order of importance of parameters when edited
in an existent PID.
4.15.4.2. PID base configuration
The Base section lets you set PID base parameters. To
open the base parameter page, double-click the Base button and select Base from the drop-down menu. The Base
page can be opened from other pages in the Base section
by touching key 1 on the left.
The number of the PID to be set is displayed at the top of
the screen and can be changed using the - and + keys.
Turn the PID on and off with the EN button. The key turns
green when the PID is enabled.
The value can be entered with the virtual keyboard by
touching some parameters.
The available parameters and functions are:
• RATIO: indicates the value of the ratio and is only
displayed if Ratio operations were set in the Synoptic
menu.
• SP: setpoint, value to be reached and maintained.
• PV: process value, current value (read only).
• Group: group of PID parameters used for regulation
chosen from the 10 available. Groups are a permanent
setting, and so if the device is restarted, group 1 will
always be set. Their principal use is in combination
with the programmer, in which the regulation unit can
be chosen for each segment.
• PID / ON-OFF: touch the key to alternatively enable
automatic regulation (PID) or ON-OFF.
• HEAT: turns the heating function on (green) or off.
• COOL: turns the cooling function on (green) or off.
• CT s : Cycle time, that is, the duration of the digital
output cycle. If set to 0, cycle time is as short as possible (Burst Firing mode); otherwise, it will be the time
shown in seconds. Available separately for Heat and
Cool functions.
• PB: Proportional band, meaning the proportional band
used for PID regulation. Available separately for Heat
and Cool functions. In the case of ON/OFF control, this
parameter represents hysteresis (HYS)
• IT m: Integral time, meaning the integral time used for
PID regulation. Available separately for Heat and Cool
functions. The parameter is not displayed if manual or
ON-OFF regulation is enabled.
• DT m: Derivative time, meaning the derivative time
used for PID regulation. Available separately for Heat
and Cool functions. The parameter is not displayed if
manual or ON-OFF regulation is enabled.
Note
If you choose Burst Firing management (CT=0.0), digital
outputs will be controlled (with On and Off times of no less
than 100 ms) to distribute dispensation of the required power as uniformly as possible and in as little time as possible.
If you choose a cycle time other than zero, on the other
hand, control of the On and Off times of digital outputs
will be managed simply to ensure that the ratio with the
selected CT time corresponds to the required power. In this
way, digital outputs may be controlled for times of no less
than 25ms.
If, for example, we wish to deliver power at 50.0% with
CT=0.0, the outputs will be On for 100ms and Off for
100ms. At 75.0% power, they will be 300ms On and 100ms
Off, followed immediately by another 300 ms On, and so
on.
In the case of CT=10.0s, on the other hand, at 50.0% we
will have a period of 500ms On and another 500ms Off.
With power at 75.0% it will be 7500ms On and 2500ms Off,
followed by another 7500ms On, and so on.
Power displays the percent power currently in use or if
used for heating or cooling.
The value indicated therefore represents the amount of
power truly delivered on the physical outputs of the
instrument, considering the evental contributions of the
parameters GRAD OUT and the SOFT START.
The pure Power % calculated by the PID algorithm is available on the page BASE2 and in the PID_nn_MAN variables.
The A / M icon indicates whether the operating mode is
automatic (A) or manual (M).
The ST icon light turns on during self tuning.
4.15.4.3. PID advanced configuration
The Base 2 section lets you set PID advanced parameters.
The number of the PID to be set is displayed at the top of
the screen and can be changed using the - and + keys.
Turn the PID on and off with the EN button. The key turns
green when the PID is enabled.
The value can be entered with the virtual keyboard by
touching some parameters.
The available parameters and functions are:
• RATIO: indicates the value of the ratio and is only
displayed if Ratio operations were set in the Synoptic
menu.
• SP: setpoint, value to be reached and maintained.
• PV: process value, current value (read only).
• Group: group of PID parameters used for regulation
chosen from the 10 available. The groups are used to

4. CONFIGURATION
preconfigure sets of operating parameters that can
easily be called up. The number of parameters available
to groups is limited to those regarding PID control for
heating and/or cooling. The parameters for all groups
are overwritten at the end of the self-tuning process.
The group will be set to 1 at the time of start-up.
• Man: touch the key to enable or disable manual regulation. The key turns green when on.
• P man: percent power that can be set in manual mode.
This percentage remains identical to the automatic
power when the PID is not in a manual mode. Otherwise, it can be set. The PID_MAN_POW_n variables allow
you to manage this parameter in GETlogic and GETview
• Antispike filter: antispike filter representing the
minimum duration of an ON or OFF impulse on digital
outputs, measured in seconds. This parameter is not
displayed if manual control or burst firing control (with
CT set to 0) is enabled.
• Soft start: enables gradual initial power distribution. If
enabled (value other than 0), the next time the instrument is turned on power will not be deliverable at
100% right from start-up, but will follow a time ramp
set in minutes.
For example, set 10 minutes to achieve: 1 minute
after turning on, maximum power will be 10%, after
5 minutes it will be 50% and maximum power will be
reached after 10 minutes. The power shown in the
page PID cfg reveals the effective power delivered at
that time on the physical outputs of the PID. The power
calculated by the PID algorithm alone is available in the
BASE2 page and in the PID_nn_MAN variables.
• Dead band: Symmetric dead band around the SETPOINT where the PID does not change power distributed (unless derivative action). The parameter is not
displayed if manual regulation is enabled. Proportional
band calculation is reconstructed on the basis of dead
band. When we enter dead band, global control will
also change slightly.
• Self T on: touch the key to enable Self Tuning, meaning a one-shot procedure to be run with start from
room temperature. If there is a difference between PV
and SETPOINT (in terms of absolute value) of greater
or less than 5% of the bottom of the scale (HIS-LOS),
self tuning cannot be activated. The key turns green
when on. The parameter is not displayed if manual
regulation is enabled. The Self Tuning process modifies
the parameters of all 10 parameter groups.
Self tuning consists of assessment of response to
system step, calculating control parameters which
optimise power delivery. The Self Tuning phase starts
providing the max power untill the PV reaches a value
in the middle between the starting value and the setpoint, than the power is switched off and it is evaluated
the overshoot of the system.
• Sts: self tuning status, indicated by a red LED when
on. The parameter is not displayed if manual regulation
is enabled.
Power displays the percent power calculated at that
time by the PID and if used for heating (red LED) or
cooling (blue LED).
4.15.4.4. PID limit configuration
The Base 3 page lets you set PID limits.
The number of the PID being examined, which may be
changed using the - and + buttons, appears at the top of
the screen.
Turn the PID on and off with the EN button. The key turns
green when the PID is enabled.
The value can be entered with the virtual keyboard by
touching some parameters. The available parameters are:
• RATIO: indicates the value of the ratio and is only
displayed if Ratio operations were set in the Synoptic
menu.
• SP: Setpoint, value to be reached and maintained.
• PV: Process value, current value (read only).
• Comma Red: shows, in display only mode, PID pa-
rameters with one less decimal place than the Process
Value variable. Therefore, this operation does not
affect controller precision. The key turns green when
Comma Red is enabled.
• HIS: Upper range limit.
• LOS: Lower range limit.
• HIL: Maximum settable set point.
• LOL: Minimum settable set point.
• HPH: Maximum power limit in heating.
• HPL: Minimum power limit in heating.
• CPH: Maximum power limit in cooling.
• CPL: Minimum power limit in cooling.
Power displays the percent power calculated at that time
by the PID and if used for heating (red LED) or cooling (blue
LED).

4. CONFIGURATION
4.15.4.5. Configuration of PID Gradient
The gradient page is used to set a gradient on variation of
the PID SetPoint or variation of power.
There are two parameters for gradient on variation of the
SP:
• GRAD INC: SP increase gradient
• GRAD DEC: SP decrease gradient
• GRAD OUT: gradient of the variation in output power,
acting on the variation of delivered power (%) per sec-
ond and active all the time.
If GRAD INC and GRAD DEC are used, the SSP variable will
show the current set point.
GRAD INC and GRAD DEC are expressed in the units of
measurement of the PV / seconds or minutes. The time
base may be set by pressing the appropriate button. GRAD
OUT is expressed as a percentage.
These parameters are only active when PID is set to
automatic, Self Tuning is disabled and there is no active
programmer for the PID in question.

motor requires to move it from the “fully closed” to
“fully open” position or vice versa.
• Man: touch the key to enable or disable manual regulation. The key turns green when on.
• T_LO: Minimum pulse: expressed as a percentage
(with a resolution of 0.1%) of the actuator time, it
represents the minimum valve position variation corresponding to the minimum power variation provided
by the controller (power under which the actuator does
not respond physically to the command).
Increasing T_LO decreases the wear of actuator to the
detriment of positioning precision. The minimum pulse
duration can be set in T_ON as a percentage of the
actuator time. When you set T_LO, the same value is
automatically set in T_ON.
• T_HI: Impulsive tripping threshold: expressed as a percentage (with resolution of 0.1%) of the actuator time,
it represents the deviation of position (required position - real position) under which the switching request
becomes impulsive.
T_HI is only active with T_OF = 0. The kind of impulsive approach allows fine control of the valve position,
which is useful especially in cases of high mechanical
inertia.
• T_ON: is the minimum time of the control valve pulse
expressed as a percentage of the actuator time. You
should set T_ON to the same value as T_LO.
• T_OF: is the minimum time between two valve ON
commands expressed as a percentage of the actuator
time.
Setting T_OF = 0 excludes the function.
Setting T_OF ≠ 0, valve switching becomes impulsive
throughout the position deviation (pulse ON Time = T_
ON and OFF time = T_OF). A value set in T_OF <T_ON
is forced to T_ON.
The Valve page lets you configure valve control. This type
of control is compatible with both regulation in cascade and
regulation as a ratio. The page only opens if Valve mode
was set in the Synoptic page for the PID.
To open the valve page, double-click the Base button and
select Valve from the drop-down menu. The Valve page can
be opened from other pages in the Base section by touching key 4 on the left.

A bar graph displays the level of valve opening, even in percent. 0% means valve fully open, 100% valve fully closed.
Warning! The valve opening indication is linear, a percentage value of the total valve travel time, result of a pure linear
calculation.
The opening reading is real at the travel limits and in the
middle.
In order to have a real information about the phisical position of the valve on all the travel, so the real opening for the
fluid flow, a position feedback signal must be used.
Power displays the percent power calculated at that time
by the PID and if used for heating (red LED) or cooling (blue

Turn the alarm on and off with the EN button. The key turns
green when the alarm is enabled.
The settable modes are:
• On EN / On DIS: The parameter sets alarm behaviour
upon turning on the instrument. If the parameter is “On
EN” , if the process variable exceeds the limits of the
alarm threshold, the alarm will go off when the controller is turned on. If the parameter is “On DIS”, the
’alarm will not go off until the alarm threshold value has
been intercepted at least once since the controller was
turned on.
• Direct/Reverse: with Direct, a reference higher than
the alarm threshold triggers the alarm, with Reverse,
the alarm is triggered when the reference is lower than
the alarm threshold.
• Absolute/Relative: with Absolute, the reference is
compared to a constant alarm threshold. With Relative,
the reference is compared to a dynamic THRESHOLD
=SP+Offset set.
• Normal / Symmetric: if Symmetrical is selected, there
will be a double alarm symmetrical to the threshold
itself.
Power displays the percent power calculated at that time
by the PID and if used for heating (red LED) or cooling (blue

enabling of the PID. They may therefore be used even if the
PIDs are off and with variables unrelated to process control.
The value can be entered with the virtual keyboard by
touching some parameters.
The available parameters are:
• ALARM: alarm threshold, that can be relative or absolute.
• REF: reference to be compared with the alarm threshold.
• HYST: alarm hysteresis.
• DELAY: alarm activation delay, expressed in minutes

Management of HB alarms
Single-phase load: there is only one current signal, so its
management is simple. Simply enter the security band for
ON current and the maximum limit for OFF current. Take
into consideration that not only a failure (or deterioration) of
loads can cause a variation in current, but also oscillation
of line voltage. You should therefore set thresholds with a
certain amount of margin, capable of “tolerating” oscillation
in the power supply.
Three-phase load:
With a three-phase system you will need to set 2 TAs.
Let us consider the case of a symmetrical, balanced threephase system with balanced loads.

4.15.4.9. PID variable configuration
The Variable section lets you associate variables to PID
inputs and outputs.
The displayed screen depends on the PID operating mode,
that is set in the Synoptic section.
CASE 1) closed triangle load, a failure in a resistance
(open circuit) generates a drop of about 42% in current on
other branches. So if there is a failure, at least one CT will
show a drop in current of about 42%.
CASE 2) load is star without neutral, a failure in a resistance generates total absence of current on the phase
connected with the faulty resistance, and a drop of about
13% in the other two phases.
And so in case 1, the variation in current will be easy to see
with good sensitivity in at least one TA. Even if the system
is not ratiometric with line voltage, its nominal fluctuation
(+10%/-10%) will NOT create false alarms. In conclusion,
the breakage of a resistance is always detected by setting
the threshold LOW_ON>58%. This means we can practically reach 70% (with no risk of false alarms due to line
variations).
In case 2, seeing as the CT may not be connected to the
faulty line (where the fault is evident), it will be necessary
to tighten the alarm threshold and set LOW_ON>87%. As
the system is not ratiometric with line voltage, fluctuation
of (+10%/-10%) can result in false alarms. It is therefore
suggested that you set the value of LOW_ON to 90% (with
a slight risk of false alarm due to the line if it drops by 10%).
To ensure secure interception of the failure under any conditions, independently of changes in voltage, use of 3 TAs
will be necessary,
Through logical functions and the available CT variables (if
the system configuration has at least 3 TAs), you can check
that each line does not go down to zero (a clear fault condition). In this way you are immune to line oscillation.

to manage a single PID (PID1) loop and display an image of
the machine controlled by the controller.
The following components will be added and set in the
page:
1. Bar to graphically display the PID1 process value (PV)
percentage.
2. Bar to graphically display the PID1 setpoint value (SP)
percent.
3. Bar to graphically display the PID1 output value (OUT)
percentage.
4. Numeric display of the PID1 process value (PV).
5. Numeric display of the PID1 setpoint (SP) and its ability
to be edited.
6. PID1 HEAT control status display LEDs.
7. PID1 COOL control status display LEDs.
