IMPORTANT RECOMMENDATIONS
 The
symbol alerts the user of non-insulated “dangerous voltage” within the product area that
is sufficiently high to constitute a risk of electric shock to persons.
 The
symbol alerts the user of important operating and maintenance (assistance) instructions
found in the documentation attached to the device.
 Dixell Srl cannot accept any liability for damages caused by modems that are not supported. Dixell
Srl reserves the right to modify this manual without prior notice. The documentation can be
downloaded from www.dixell.com even prior to purchase.
 Dixell Srl reserves the right to change the composition of its products, even without notice, ensuring
the same and unchanged functionality.
 This manual forms part of the product and must always be kept near the device for easy and quick
reference. The device cannot be used as a safety device. Verify the limits of application before using
the device.
 Verify that the power supply voltage is correct before connecting the device. Do not expose it to
water or humidity: use the controller only within the operating limits, avoiding sudden changes in
temperature and high atmospheric humidity in order to prevent condensation from forming.
Recommendation: disconnect all the electric connections before performing any maintenance.
Insert the probe where it cannot be reached by the End User. The device must not be opened.
Consider the maximum current that can be applied to each relay. Make sure that the wires for
the probes, the loads and the electrical power supply are separated and sufficiently distant from
each other, without crossing or intertwining with each other. In the case of applications in
industrial environments, it may be useful to use the main filters (our mod. FT1) in parallel to the
inductive loads.
 The customer shall bear full responsibility and risk for product configuration in order to achieve the
results pertaining to installation and/or final equipment/system. Upon the customer's request and
following a specific agreement, Dixell s.r.l. may be present during the start-up of the final
machine/application, as a consultant, however, under no circumstances can the company be held
responsible for the correct operation of the final equipment/system.
 Since Dixell products form part of a very high level of technology, a
qualification/configuration/programming/commissioning stage is required to use them as best
as possible. Otherwise, these products may malfunction and Dixell cannot be held
responsible. The product must not be used in any way that differs from that stipulated in the
documentation.

The device must always be inserted inside an electrical panel that can only be accessed by
authorised personnel. For safety purposes, the keyboard must be the only part that can be
reached.

The device must never be hand-held while being used.

INTRODUCTION
iPRO is the range of programmable controllers manufactured by Dixell.
The range consists of programmable controllers, I/O expansions, drivers for electronic valves and graphical
interfaces adapted to cover any type of application in the air-conditioning sector, cooling sector and any
relative area. As the system is one of the most technologically advanced, it is flexible and can be customised
for it to be adapted to the user's particular requirements.
3.
GENERAL SPECIFICATIONS
The Dixell programmable controllers are all powered at 24Vac/dc and use a high speed performance 32-bit
ARM9 (200 MHz) microprocessor. The models differ in size (10 DIN or 4 DIN) and number of inputs and
outputs (analog and digital).
One of the features that distinguishes the iPRO controllers is the vast range of connection options with
external devices, Dixell as well as other brands. CANBus, RS485 Master and Slave, and an Ethernet and
USB port provide maximum flexibility of integration with the outside world. MODBUS RTU protocol, one of
the most popular in the world, is used for serial communication.
Up to 80 MB of flash memory are entirely available to the user, according to the model. All the inputs and
outputs are fully configurable.
PROCESSING ENVIRONMENT
All Dixell programmable controllers use the following software as a processing environment:
 ISaGRAF® to process the iPRO application.
 VISOPROG to process the LCD graphic interface application (VISOGRAPH)
ISaGRAF® software is used worldwide and allows those with no programming experience to build
applications ranging from the simplest to the more sophisticated. The vast range of the most popular
programming languages (Structured Text, Function Block Diagram, Ladder Diagram, Instruction List,
Sequential Function Chart, Flow Chart, FBD IEC 61499) provides all programmers with access to the
processing environment. Thanks also to the extensive libraries of blocks already developed by Dixell, the
processing and debug times are reduced.
The SIMULATION (verification of the application without using the controller) and DEBUG options
(verification of the actual application within the controller), allow the user to block and force the value of the
variables to speed up the testing times.
Fields of application
The possibility of all-round configuration allows the Dixell iPRO programmable controller to be used for any
type of application. The same applications can be downloaded in the various models available (obviously
adapting the number of inputs and outputs).
The hardware has already been used for the following applications:


6.6.1 Tool with Clock On Board (Optional)
If the message “rtC” appears in the bottom screen alternating with the temperature / pressure when the tool
is powered it means it is necessary to adjust the clock.
If the probes designed to control the unit are not connected or are broken, the relative alarm will
appear in the two screens. It is nevertheless possible to proceed with regulating the clock or
programming.
CAUTION
The clock is optional. If you require the use of an instrument with an on-board clock, this must be
specified in the purchase order
6.6.2 How to Regulate the Clock
1. Press the Menu button for a number of seconds until the word “Hour” appears in the bottom screen, and
the memorised time in the top screen.
2. Press the SET key: the hour starts to flash.

Low pressure alarm
Bypass time for low pressure alarm from digital / analog input from the
start-up of the first compressor of the circuit and from the shut off of the
last compressor of the circuit
This defines low pressure alarm operation with pump-down
enabled:
0 = the low pressure alarm is independent from pump-down
1 = the low pressure alarm is inhibited during compressor shutdown
in pump down and when the compressor is stopped. When
restarted, if ID is active, the solenoid valve opens but the
compressor does not start up until the low pressure switch is
deactivated. If the pressure switch is not deactivated within the
AL01 time, the low pressure alarm is triggered.
2 = the low pressure alarm is inhibited during compressor shutdown
in pump down, when the compressor is stopped and for AL01 time
when the compressor restarts

This allows you to set a differential that determines the alarm to be reset.
Anti-freeze alarm delay (low outfeed air temperature in air/air unit) from
the start-up of the unit in heat pump mode
Caution: if, in remote Stand-by/OFF mode, the unit presents an antifreeze alarm situation and the AL43 time is not zero, by selecting h.p.
mode from the key or from the digital input, this resets the anti-freeze
0
situation and allows the compressors to start up for AL43 time as the unit
heats the water or the air. Once the AL43 delay lapses, if the anti-freeze
regulation probe still detects a temperature of < AL41 set point for at least
AL44 seconds, the unit is blocked and an anti-freeze alarm is triggered.
Anti-freeze alarm delay, low ambient air temperature, low output air
temperature in heat pump mode.
This allows you to set an amount of time during which the temperature
0
must stay below the set point set by PAR. AL41 so that the anti-freeze
alarm is triggered.
