1.1 General description
The FREE Panel (EVP) is a fully programmable panel mounting solution with LCD display made by Eliwell,
suitable for managing a wide range of HVAC/R and many other applications, from the simplest to the most complex.
The EVP can be used as a system controller, with gateway functions; used in combination with the FREE Evolution and
FREE Smart or third-party controllers it guarantees high performance in terms of memory, connectivity and user interface
as well as straightforward programming, maintenance and servicing.
The EVP is designed for panel mounting, and can also be wall-mounted using a special backplate, available as an accessory.
Programming of the EVP is managed via the FREE Studio development tool, which makes it possible to quickly and
reliably create and customise new programs for all types of application.
The use of several different programming languages in accordance with IEC61131-3 standard (industrial control
programming ), makes it possible to develop new algorithms or entire programmes totally unassisted, which can then be
uploaded to FREE Evolution modules via PC, guaranteeing maximum confidentiality with appropriate security.
The EVP can be used to:
manage a local menu created with the FREE Studio User Interface

3ELECTRICAL CONNECTIONS
3.1 General warnings
Before proceeding with any operation, make sure the device is connected to a suitable external transformer. The
following rules must be followed when connecting cards to each other and to the application:
Loads that exceed the maximum limits stated in this manual must not be applied to outputs.
When connecting loads, follow the circuit diagrams carefully.
To avoid unwanted couplings, wire all SELV (safety extra voltage) users separately from high voltage
users.
IMPORTANT!
Make sure the appliance is switched off before working on electrical connections.Operations must be carried out
by skilled personnel. To ensure proper connections,comply with the following:
Power supplies other than those specified can seriously damage the system.
Select cables of suitable section for the terminals used
Separate the cables of probes and digital inputs from inductive loads and high voltage connections to prevent
any electromagnetic interference. Do not place probe signal leads near other electrical equipment (switches,
meters, etc.)
Make connections as short as possible and do not wind them around electrically connected parts.
To avoid electrostatic discharges, do not touch the electronic components on printed circuit boards.
The device must be connected to a suitable transformer that complies with the specifications indicated in the
Technical Data chapter.
3.1.1 Power supply
Important!
Make sure that the power supply is of the correct voltage for the instrument.
3.1.2 Analogue Inputs-Probes
Probes have no connection polarity and can be extended using a normal two core cable (note that the extension of the
probes influences the electromagnetic compatibility (EMC) of the instrument: take great care with the wiring).
Important!
Pressure probes have a specific connection polarity, which must be observed.
Signal leads (temperature/pressure probes, digital inputs, RS-485/CAN-BUS serials and the electronic supply) must be
routed separately from power cables.
Use probes supplied by Eliwell. Contact Eliwell sales department for parts availability.
3.1.3 Serial connections
On-board CAN as standard
On-board RS485 as standard
On-board ETHERNET serial as standard
Pay special attention when connecting serial lines: Do not connect instruments that communicate using RS485 serial to
CAN terminals, or CAN instruments to RS485 terminals.
CAN
NOTE 1
Use a shielded and "twisted pair" cable with two 0.5mm2 conductors, plus braiding (ideally Belden cable model
3105A (characteristic impedance 120 Ohms) with PVC sleeve, 2 conductors plus braid, 22 AWG, nominal capacity
between conductors 36pF/m, nominal capacity between conductor and shielding 68pF/m).
Always follow regulations applicable to the routing and connection of cables. Make certain that data transmission
circuits are properly separated from power lines.
For connections over longer distances, it is better to end the line with resistors on both ends, inserting the two R
TERM jumpers (available on the terminal strip beside the CAN serial as the default factory configuration).
NOTE 2
The maximum distance depends on the baud setting.
Kb/s (Kbaud) On-board

INSTALLING THE RS-485 NETWORK
NOTE 1
Use a shielded and "twisted pair" cable with two 0.5mm2 conductors, plus braiding (ideally Belden cable model 8762 with
PVC sleeve, 2 conductors plus braid, 20 AWG, nominal capacity between conductors 89pF/m, nominal capacity between
conductor and shielding 161pF/m).
See EN 50174 standard on IT cabling for indications on how cables should be routed.
Make certain that data transmission circuits are properly separated from power lines.
An RS-485 network up to 1200m in length with a maximum of 256* devices can be connected straight to the controller.
*Note: example of Evolution Modbus Slave with single Master supervisor.
This length can be extended and the number of devices for each channel increased using appropriate repeater modules.
NOTE 2
Single terminal strip with 3 conductors: use all 3 conductors (“+”, “-“ for the signal and “GS” for the braid).
NOTE 3
Attach the 120 (Ohm) 1/4W resistors between the "+" and "-" terminals of the interface and the last controller in each
branch of the network.
NOTE 4
Maximum settable speed 57600 baud. Higher speeds are envisaged for local connection to FREE Studio Device and tests.
ETH
The Ethernet connection allows the FREE PANEL to communicate on an Ethernet network using TCP/IP protocol.
The connection allows:
connection of different controllers and/or applications exchanging variables and/or parameters (network).
connection of a supervision system using Modbus TCP/IP protocol
connection of an IEC 61131-3 Free Studio development system
NOTE: The Ethernet connector shield is internally connected to the earth of the instrument and therefore to the reference
of the input and output channels.

The temperature and humidity measurement, as well as the corresponding precisions and tolerances, refer to the
application point of the probes inside the instruments.
If these same measurements are to be referred to air conditions outside of the instrument, e.g. ambient measurements,
account must be taken of offset (differential) parameters that depend on the installation and usage conditions of the
instrument itself.
The differentials e.g. Calibration parameters that can be set are
for on-board (built-in) sensors, 'compensation' parameters are also available
Factory values
for these
offsets assume
a typical
installation with wall mounted backplate in a non-ventilated environment and with the display backlighting mainly OFF. In
these conditions the following calibration values are obtained:
Compensation_AI1 = -12.0 °C
Compensation_AI4 = -10.5 °C
If the usage conditions require the backlight to be mainly ON, the values must be modified as follows:
Compensation_AI1 = -15.0 °C
Compensation_AI4 = -13.0 °C
For other mounting conditions, it is advisable to carry out calibration during installation, checking the temperature and
relative humidity differences between the external air and the internal probes and if necessary correcting the parameters
Compensation_AI1/ Compensation_AI4
In any case it is possible to achieve a precision of +- 1°C on the temperature measurement and +- 3%RH on the relative
humidity measurement.

6PARAMETERS
User-parameterization renders the FREE Panel EVP fully configurable.
Parameters can be changed using:
Keys on the EVP front panel
PC and FREE Studio software
The following sections provide a detailed analysis of each parameter, divided into categories (folders).
6.1 Table of parameters
The following table contains all the device configuration parameters available in FREE Studio Device and in the
DIAGNOSTICS (DIA) / BIOS Parameters menu
Description of columns:
This indicates the label of the FREE Studio Device folder containing the parameter in question
A group of these parameters is available on the LCD display in the DIAGNOSTICS (DIA) menu
Refer also to the following table:
(x) if present (loaded to EVP)
The local menu - if present (uploaded to EVP) - is defined with the Network label
This indicates the label used to display the parameters
Indicates the address of the modbus register containing the resource to be accessed.
Indicates whether the device MUST be rebooted after the parameter has been changed.
Y=YES the device MUST be rebooted to save the change.
N=NO the device DOES NOT need to be rebooted after changing the parameter
Indicates if resources are read/write, read-only or write-only:
R The resource is read-only
W The resource is write-only
RW The resource can be both read and written to
Indicates the size of the data in bits.
When the field indicates “-1”, the value read by the register requires conversion, because the value represents a number
with a sign. In other cases the value is always positive or null.
To carry out the conversion, proceed as follows:
If the value in the register is between 0 and 32.767, the result is the value itself (zero and positive values)
If the value in the register is between 32.768 and 65.535, the result is the value of the register – 65.536 (negative
values)
Describes the interval of values that can be assigned to the parameter. It can be correlated with other instrument
parameters (indicated in the parameter label).
Indicates the factory setting for the standard model of the instrument.
Unit of measure for values converted according to the rules indicated in the CPL column
The unit of measure shown is an example only, as it may change depending on the application (e.g. parameters with a U.M.
in °C/bar could also have %RH)
