1. INTRODUCTION AND GENERAL FEATURES
pCO sistema: CAREL’s proposal for programmable controllers.
It consists of programmable controllers, user interfaces, gateways and
communication interfaces, and remote management systems to offer
the HVAC/R market a control system that’s powerful, flexible and easy
to interface to the most commonly-used building management systems.
pCO sistema is very reliable and can be easily customised to differentiate
the air-conditioning or refrigeration unit control system.
All versions of these controllers use a 32-bit microprocessor and either
4 or 8 MBytes of memory so as to ensure high performance in terms of
speed and memory space available. The pCO sistema controllers also
come in different sizes according to the number of inputs and outputs,
giving the best price/performance ratio. Given the increasing need for
integration, the pCO sistema family controllers can interface with some
of the most commonly-used serial communication standards, and when
fitted with optional cards can be integrated into BMS systems.
The pCO* family can connect different types of sensors (e.g. ratiometric,
NTC, 4 to 20 mA, etc.); a built-in terminal is available; there are one or two
serial ports (depending on the model) to offer connection to controlled
field devices (valves, I/O expansions, electronic valve drivers…). In
addition, on models where featured, the controllers have 2 USB ports for
uploading and downloading files.
All these features place our controllers at a level of excellence in fulfilling
the needs of the HVAC/R market.
1.1 Programmability
The CAREL pCO sistema controllers can be programmed using 1Tool
development software, offering the following advantages:
• software portability on different CAREL hardware. applications
developed for the pCO can be simply and quickly transferred to
another hardware platform and vice-versa, modifying only the inputs
and outputs;
• rapid development, at competitive costs, of custom programs;
• reliability guaranteed by the use of standard routines, tested in the
field.
The use of 1Tool, moreover, ensures the customer the maximum level of
privacy and self-management when developing new programs on their
own. The possibility to use the same hardware for different applications
allows standardisation, with the clear advantages of being able to feature
in-circuit and functional testing and burn-in procedures on all of the
products and consequently reach a high level of reliability, both overall
and in terms of the individual electronic components.
1Tool: exclusive, easy to use CAREL development software for
programming, simulation, supervision and definition of pLAN networks
using CAREL terminals and pCO programmable controllers.
Applications
TheprogrammabilityofthepCOensuresabsoluteflexibilityofapplication.
The same standard hardware can be used to control:
• chillers and heat pumps;
• roof-top units;
• air-conditioners;
• small/medium-sized air handling units (on request);
• showcases (on request and to specifications);
• cold rooms (on request and to specifications);
• curing rooms;
• compressor racks;
• universal stage controllers.
Other types of programs can be developed to specific customer
requirements.
Hardware architecture
The pCO architecture features:
• the pCO controller, fitted with a 32-bit microprocessor for running the
control program, and the set of terminals required for connection to
the controlled devices (for example: valves, compressors, fans). The
program and the parameters are saved permanently in the FLASH
memory, preventing data loss in the event of power failure (without
requiring a backup battery). The pCO also allows connection to a local
pLAN network made up of a series of pCO boards and terminals. Each
board can exchange information (any variable, digital or analogue,
according to the application software) at high transmission speeds.
connection to the supervisor/telemaintenance serial line, over the
RS485 standard, is made using the optional serial cards (PCO004850)
and the CAREL or Modbus® communication protocol.
• The terminal, also managed by microprocessor, fitted with display,
keypad and LEDs to allow the programming of the control parameters
(set point, differential band, alarm thresholds) and basic functions by
the user (ON/OFF, display of the controlled values, optional printing).
The terminal does not have to be connected to the pCO for normal
operation, but can be used for the initial programming of the funda-
mental parameters.
The power of the application software means that the user terminal
allows:
• initial programming of the unit, with password-protected access;
• the possibility to modify, at any time, the fundamental operating
parameters, optionally protected by password;
• display and audible signalling (by buzzer) of any alarms;
• display of the active functions by LED;
• display of all the values measured.

500 mAT fuse;
• the two 230/24 Vac inputs on J8 and J12 have the same common pole
and therefore both will be 24 Vac or 28 to 36Vdc, or 230 Vac. There is
double insulation between the two inputs and the rest of the controller.
• for DC digital inputs (28 to 36 Vdc), either the + or the — can be
connected to the common (IDC1).
• the rating of the external contact connected to the digital inputs must
be at least 5 mA.
Note: separate as much as possible the probe signal and digital
input cables from the inductive load and power cables, to avoid
possible electromagnetic disturbance.

When configured as fast digital inputs, B4 and B5 can measure a signal
with a maximum frequency of 2 KHz and a resolution of ±1 Hz. This
is possible as the BIOS provides the application program two pairs
of variables that count the zero crossing of the input signal and the
corresponding frequency in Hz.

For the connections see Fig. 2.a and 2.b (reference NO*, NC* and C*).
Note that outputs with changeover contacts are kept separate (i.e.
without poles shared between outputs). The groups of 3 outputs have 2
“common”contacts for easier installation.
Make sure that the current running through the common terminals
does not exceed the rated current of an individual terminal, that is, 8 A.
Minimum relay contact current: 50 mA.
Insulation distance The relay outputs have different features, depending on the model of pCO5. The outputs can be divided into groups. Between
groups (cells in the table) there is double insulation and consequently these may have different voltages. There is also double
insulation between each terminal of the digital outputs and the rest of the controller. The relays belonging to the same group
(individual cell in the table) have basic insulation and therefore must have the same power supply (24 Vac or 230 Vac).

“pCO5”+0300009EN rel. 1.2 — 24.04.2014
Version with electronic expansion valve driver
The pCO5 Medium size features an optional new integrated solution:
the version with built-in EVDevo driver, single or twin. The driver card is
housed on the pCO5 in the socket provided for the inputs / outputs on
the Large size board, hence the reason it’s only available on the pCO5
Medium (not Small, Large, nor ExtraLarge) and doesn’t require an external
power supply.
The built-in driver replicates all the hardware and functions logical of
the “EVDevolution TWIN” driver, i.e. independently controls one or two
electronic expansion valves with two-pole stepper motors. The only
difference between the two versions is the absence of the relay output.
For details on the valve control logic, setup and installation see the
EVDevo manual (code + 0300005EN).
In the same way as EVDevo, on the pCO5 the integrated driver is available
in the CAREL and Universal versions. The “Universal” models are used to
control both CAREL electronic expansion valves and products made by
other manufacturers (see the table below), while the CAREL models only
manage CAREL valves.

Tab. 2.l
This version of pCO5 Medium with built-in EVDevo driver can be
integrated with the energy storage module (PCOS00UC20), made using
special capacitor technology called Ultracapacitor, so as to ensure the
electronic valve closes in the event of power failures. The module only
powers the driver and not the pCO5 this in integrated into.
Warning: the pCO5 with valve driver and PCOS00UC20, EVD0000UC0 or
EVBAT00400 module must be powered at 24Vac so that emergency valve
closing is ensured in the event of power failures.
Serial communication and programming
Communication between the pCO5 and its built-in EVDevo driver is
managed internally using the Fieldbus2 serial port. The FieldBus2 serial
port (J26) is however electrically insulated from the driver serial line:
this ensures that in the event of external faults on the line connected
to FBus2, the internal driver can continue working independently and
correctly.
The driver can only be configured exclusively using the pCO5 application
developed in 1Tool, no external displays are available for the EVDevo.
The 1tool development environment features a module for managing
the EVDevo: the same module can be used to manage the internal driver,
as if it were managing an external EVDevo connected to the FBus2 port.
pCO5 Medium manages the integrated driver board as an EVDevo Twin
external connected to Field Bus 2. At a 1Tool application program level,
the valve driver must be connected to FBus2. Consequently, any other
devices physically connected to the Fbus port (J26) must have the same
communication protocol (CAREL Standard Master or Modbus® Master),
the same baud-rate, stop bits and parity.
It must also be remembered that the address of the internal driver is 198
(default for EVDevo), so any other devices connected to J26 must have
an address other than 198. External EVDevo drivers can be connected to
FieldBus 1 (optional card) without limits.
Example application:
Fig. 2.d
To ensure efficient data exchange between the driver EVDevo and
the pCO5, when developing the 1Tool application, if there are devices
connected to the FBus2 port (terminal J26) using the Modbus® protocol,
the number of variables exchanged in total over the serial line should be
evaluated.
Electrical connections
To simplify installation of the pCO5 with integrated EVDevo, the power
supply G-G0 at the base of the pCO5 is connected internally, using
a shielded cable, to the EVDevo: the driver thus does not need to be
powered independently.
It’s recommended to keep the digital and analogue input cables separate
from the valve power cable. All the analogue and digital inputs are
earthed to GND, and consequently the application, even temporary, of
voltages exceeding ±5 V to these connections may cause irreversible
damage to the driver. As GND is the common earth for all the inputs, this
should be replicated on the terminal block.

Fast digital input specifications (ID1)
The fast digital input (ID1) can be configured via software in two different
operating modes, with the following characteristics:
• mode one: normal or standard digital input;
• mode two: fast digital input.
When configured as a fast digital input, ID1 can measure a signal with a
maximum frequency of 2 KHz, resolution +/- 1 Hz. This is made possible
by the BIOS, which provides the SW application with two variables that
the count the number of times the input signal crosses zero and the
corresponding frequency in Hz.
Note: see details in the paragraph 4.5 on digital inputs
Normal and fast digital input specifications
The maximum current available to the digital input is 5 mA (consequently
the rating of the external contact must be at least 5 mA).

Digital outputs
pCO compactTYPE A features 7 digital outputs, while pCO compactTYPE
B features 6 digital outputs, both with electromechanical or solid state
relays (SSR).To simplify wiring, the common terminals of some relays have
been grouped together, depending on the insulation distance.
Within a group, the relays only have basic insulation between them and
thus must be powered at the same voltage (generally 24 Vac or 110 to
230 Vac). Between groups there is reinforced insulation, thus the groups
can be powered at different voltages.

Various types of user terminals are available, differing in terms of:
• dimensions;
• liquid crystal display (LCD);
• number of buttons;
• number of indicator LEDs;
3.1 Graphic terminals
pGDE
The pGD graphic display is an electronic device, compatible with the
previous PCOI/PCOT terminals, used for the complete management of
the graphics, by displaying icons (defined at an application software
development level) and international fonts, in two dimensions: 5×7 and
11×15 pixels. The application software only resides on the pCO board;
the terminal does not need any additional software during operation.
In addition, the terminal allows a wide range of operating temperatures
(-20T60°C) and guarantees a high index of protection (IP65).

These versions with integrated LCD and keypad also support connection

The display contrast can also be adjusted on this version of terminal.
To do this :
1. press the Enter and Esc buttons together;
2. holding the two buttons, use Up or Down to adjust the contrast as
desired (increase or decrease).
Connecting the user terminal to the pCO board
The typical connection between the pGD terminal and the pCO is made
using a 6-wire telephone cable supplied by CAREL (code S90CONN00*,
see the table). To make the connection, simply plug the cable into the
6-pin connector on the pCO board (J10 for pCO3 and pCO1, J5 for pCOXS,
J19 pCOC), until it clicks into place. To remove the connector, lightly
press the plastic catch and remove the cable. The telephone connector
provides both the data link and the power supply to the terminal, and is
the simplest connection method; in more complex configurations, where
multiple terminals need to be connected to the pCO or to cover lengths
over 50 m, use shielded, twisted pair cable (see diagrams in chap. 5).
Warning shielded cables must be used even when the pCO is
fitted on appliances for household or similar uses, and therefore subject
to the requirements of IEC EN 55014-1 of 04/98) – (see paragraph 5.7).
When making a pLAN network of pCO controllers and terminals,
remember that one pCO can only power one pGD0/1 or pCOT/I terminal.
If needing to manage more than one terminal or for the pGD2/3, an
independent power supply is required (see diagrams in chap. 5). The
direct current available at Vterm (J24 for pCO3, J9 for pCO1) can power
an Aria or PLD terminal with a maximum current of 2 W. Absence of the
terminal does not compromise operation of the pCO.
3.2 Optional cards for pCO sistema
Serial cards for supervision and telemaintenance
RS485: PCOS004850
Fig. 3.e
The PCOS004850 card is an option used to interface pCO electronic

Serial cards for connection to a“field bus”network
The optional Field bus cards provide a serial interface that allows the PCO3
and pCO1 to communicate with other devices over various standards.
Indeed, the tLAN, MP bus and RS485 options interface the pCO to a
network of devices including actuators, probes, expansions or terminals.
RS485 serial card: PCO100FD10
Fig. 3.l
The PCO100FD10 option is used to connect the pCO3 and pCO1, via an
electrically insulated interface, to an RS485 network, using the connector
with plug-in terminals on the card. The controller consequently acts
as the MASTER (i.e. supervisor), and therefore other pCO controllers or
SLAVE devices can also be connected. The meaning of the pins on the
connector are denoted by the screen printing on the card. A maximum
of 207 devices can be connected using this type of connection. If the
optional card occupies the last position on the supervisor serial line and
the line is longer than 100m, the line must be terminated by connecting
a 120Ω — 1/4W resistor to the terminal pins.
For SLAVE operation, on the other hand of type, only one pCO can be
connected to the network with this optional card.
tLAN and PST card: PCO100TLN0
Fig. 3.m
The PCO100TLN0 option is used to connect the pCO1 to a tLAN network
using two separate connectors.
The first connector is used to connect the pCO3 and pCO1 to a tLAN
network. Using this connection and a suitably-configured application in
TLAN MASTER mode, the pCO1 can interact with the pCO I/O expansion
(tLAN version — PCOE00TLN0) or with other pCO controllers fitted with a
tLAN connection, configured in tLAN SLAVE mode.
A maximum of 5 devices can be connected using this type of connection.
The second connector, on the other hand, is used to connect a PNT or PST
terminal. Using this connection and a suitably-configured application, the
pCO3 and pCO1 can interact with a PNT terminal. For both connections,
use a shielded cable with a maximum length of m.
Important: both connectors cannot be used at the same time.
MP-Bus card: PCO100MPB0
Fig. 3.n
The PCO100MPB0 option is used to connect the pCO3 and pCO1 to an
MP-Bus network made up of I/O devices using the Belimo standard. Up to
8 actuators can be connected at the same time, with a maximum distance
of 30 m (Fig. 7). To connect an active or passive temperature sensor, or a
digital contact, refer to the specific Belimo documents (www.belimo.ch).
As regards the configuration procedures for the network addresses, these
are described in the specific manuals for the individual applications.

External modules and interfaces
Interface for OEM series humidifiers (PCOUMI2000)
Fig. 3.p
The PCOUMI2000 module is an interface for pCO electronic controllers
used to allow the fundamental parameters of the OEM humidifiers made
by CAREL (high level and supply water conductivity in the cylinder, TAM
current sensor) to be controlled directly by the pCO microprocessor
electronic controller. The values measured by the sensors are converted
into signals read by the inputs on the pCO (for further information see the
user manual for the application program).
Compared to the PCOUMID000 interface, the PCOUMI2000 differs in
terms of:
• greater precision and immunity to disturbance for both the
conductivity and the level sensor;
• the “high water level” signal can be managed either by a digital or
analogue output.
Consequently, both the PCOUMID000 and the PCOUMID200 cards can be
connected to the pCO, with the only requirement being to set a special
parameter so as to allow the software to use the correct conductivity
curve..

The PCO20DCDC0 power supply module is an option for the pCO
electronic controllers.
It stabilises the 24±1 Vdc/0.7 A direct current output (from the pCO
controller) when the input voltage (power source) is in the range from
21 to 58 Vdc (for example 48 Vdc storage batteries, typical in telephone
applications).
The maximum capacity delivered is 17 W, suitable for powering any
pCO electronic controller. The input and output of the power supply
module are galvanically insulated at a functional level. For the technical
specifications, meanings of the connections (pins) and instructions on

SMART KEY (PCOS00AKY0 e PCOS00AKC0)
Fig. 3.t
The PCOS00AKY0 key is an electronic device used to program and service
the pCO sistema family controllers. PCOS00AKY0 simplifies data transfer
between the controllers installed and a personal computer by exploiting
the high capacity flash memory for storing software applications, BIOS
and variable logs. The pCO is connected directly via the telephone
connector using the cable supplied, while to transfer the data to a
personal computer, the USB adapter code PCOS00AKC0 is required
(converter not opto-isolated, for the Smart Key only). The power supply
comes either via the USB port on the PC or from the controller, therefore
no external power supply is needed.
REQUIREMENTS
Hardware requirements: type C and G Smart Keys can only copy
software between pCO devices belonging to the same family, which are
compatible in terms of RAM and FLASH memory size.
The pCO families are:
• pCO1/pCOC/pCOXS/pCO OEM
• pCO2
• pCO3
• pCO5
• pCO Compact
• Supernodo
Software requirements: the programming key is compatible starting from
Bios version 3.43 and Boot version 3.01.
For more detailed information on programming the key, see the pCO
Manager program manual.
CONNECTION
Spegnere il pCO rimuovere qualsiasi periferica connessa in rete pLAN
e Switch off the pCO, remove any peripherals connected in the pLAN
and plug the key into the telephone connector on the controller. When
switching on again all the symbols light up momentarily and the buzzer
emits a beep.
Then wait a few seconds before the key is operational.
This waiting stage is indicated by UP and DOWN symbols flashing.
At the end of this stage, the controller enters programming mode and
the start button, now on steady, can be pressed to start the data transfer.
Then the Upload/Download operations described below can be
performed.
Important: if the key is type B, C or G (in write mode) pressing the
start button immediately deletes the software already loaded on the
pCO.
Important: the key must not be removed while a write operation
is in progress to the key, as the file being transferred will be lost and the
corresponding space is not restored. To restore the original capacity all
the files will need to be deleted. If the key is type“C”or“G”, simply perform
a new application read operation.
UPLOAD APPLICATION
At the end of the connection and recognition stage between SmartKey
and pCO, the controller goes into programming mode, with the START
button light on steady. Then proceed as follows
1. Make sure the arrow is pointing in the direction of the pCO
connection. If the arrow is pointing the other way, switch directions
by pressing the MODE button
2. When this condition is true, pressing the START button automatically
activates the UPLOAD procedure (read data from SmartKey to pCO).
3. Completion of the UPLOAD procedure is signalled by the buzzer.
The operation for reading the data may take a few minutes to
complete
DOWNLOAD APPLICATION
At the end of the connection and recognition stage between SmartKey
and pCO, the controller goes into programming mode, with the START
button light on steady. Then proceed as follows
1. Make sure the arrow is pointing to the inside of the SmartKey. If the
arrow is pointing the other way, switch directions by pressing the
MODE button.
2. When this condition is true, pressing the START button automatically
activates the DOWNLOAD procedure (read data from the pCO)
3. Completion of the DOWNLOAD procedure is signalled by the
buzzer. The operation for writing the data may take a few minutes
to complete.

USB/RS485 converter (CVSTDUMOR0/CVSTDUTLF0))
Fig. 3.u
Il The USB-RS485 converter is an electronic device used to interface a
RS485 network to a personal computer via the USB port, used together
with WINLOAD. The converter is available in two versions: CVSTDUTLF0,
fitted with six-pin telephone connector, and CVSTDUMOR0, fitted with
three-pin terminal block. These are optically-isolated and cannot be
used with the Smart key. For the technical specifications, meanings of
the connections (pins) and instructions on inserting the card, see the
instructions shown on the instruction sheet included in the packaging
with the card (code +050000590).
pCOe
Fig. 3.v
The “PCOE000TLN0 and PCOE0004850” expansion card is an electronic
device that’s part of the pCO sistema family and has been designed to
increase the number of I/Os on the pCO controllers. A maximum of 5
expansion cards can be connected for each pCO controller.
Versions available:
• PCOE00TLN0 version tLAN (CAREL proprietary protocol);
• PCOE004850 version RS485 (CAREL 3.0 supervisor protocol).
For the technical specifications, meanings of the connections (pins)

Valve driver (EVO*)
Fig. 3.w
The EVD0000400 module for electronic expansion valves with two-pole
stepper motor is a controller that manages refrigerant expansion in a
refrigerant circuit. This function is achieved by optimising the opening
of the valve using a PID algorithm and some special auxiliary control
routines. The controller has a tLAN interface for connection to a Master
unit, an RS485 adapter (available on models *410, *411, *420 and *421)
that allows connection to units with the supervisor protocol, from 4800
to 19200 baud, or with the pLAN protocol. The controller automatically
recognises the protocol and the baud rate. Alternatively, the controller
can operate in stand-alone mode. As well as the serial connection, in
any configuration described above, the controller can be accessed for
configuration or monitoring via an auxiliary “service” serial port at 4800
baud with supervisor/tLAN protocol and network address = 1 (fixed). The
USB converter CVSTDUTTL0 is required to use the“service”serial port. This
connection is for temporary use (Fig. 2). If using the “service” serial port
or the supervisor protocol on the main serial port, the EVD4UI program
can be used; this has a user-friendly graphic interface and is available on
the KSA site.

4. PCO CONTROLLER INSTALLATION
4.1 General installation instructions
Installation instructions
Environmental conditions
Avoid assembling the pCO and the terminal in rooms with the following
characteristics.
• temperature and humidity that do not conform to the rated operating
data of the product;
• strong vibrations or knocks;
• exposure to aggressive and polluting atmospheres(e.g.: sulphur and
ammonia fumes, saline mist, smoke) so as to avoid corrosion and/or
oxidation;
• strong magnetic and/or radio frequency interference (therefore avoid
installing the units near transmitting antennae);
• exposure of the pCO to direct sunlight and to the elements in general;
• large and rapid fluctuations in the room temperature;
• environments where explosives or mixes of flammable gases are
present;
• exposure to dust (formation of corrosive patina with possible oxidation
and reduction of insulation).
Positioning inside the panel
The position of the controller in the electrical cabinet must be chosen so
as to guarantee correct physical separation from the power components
(solenoids, contactors, actuators, inverters, …) and the connected cables.
Proximity to such devices/cables may create random malfunctions that
are not immediately evident.
The structure of the panel must allow the correct flow of cooling air.
Wiring instructions
When laying the wiring,“physically“ separate the power part from
the control part. The proximity of these two sets of wires will, in
most cases, cause problems of induced disturbance or, over time,
malfunctions or damage to the components. The ideal solution is to
house these two circuits in two separate cabinets. Sometimes this is not
possible, and therefore the power part and the control part must be
installed in two separate areas inside the same panel. For the control
signals, it is recommended to use shielded cables with twisted wires.
If the control cables have to cross over the power cables, the intersections
must be as near as possible to 90 degrees, always avoiding running the
control cables parallel to the power cables.
Carel highlights the following warnings:
• Use cable ends suitable for the corresponding terminals. Loosen
each screw and insert the cable ends, then tighten the screws. When
the operation is completed, slightly tug the cables to check they are
sufficiently tight;
• separate as much as possible the sensor signal, digital input and serial
line cables from the cables carrying inductive loads and power cables
to avoid possible electromagnetic disturbance. Never insert power
cables (including the electrical cables) and probe signal cables in
the same conduits. Do not install the sensor cables in the immediate
vicinity of power devices (contactors, circuit breakers or similar);
• reduce the path of the sensor cables as much as possible, and avoid
spiral paths that enclose power devices;
• avoid touching or nearly touching the electronic components fitted
on the boards to avoid electrostatic discharges (extremely damaging)
from the operator to the components;
• if the power transformer secondary is earthed, check that the earth
wire corresponds to the wire that runs to the controller and enters
terminal G0; this applies to all the devices connected to the pCO;
• do not secure the cables to the terminals by pressing the screwdriver
with excessive force, to avoid damaging the pCO;
• for applications subject to considerable vibrations (1.5 mm pk-pk
10/55 Hz), secure the cables connected to the pCO around 3 cm from
the connectors using clamps;
• if the product is installed in industrial environments (application of EN
61000-6-2) the connections must be less than 30 m long;
• all the extra low voltage connections (analogue and 24 Vac/Vdc or
28 to 36 Vdc digital inputs, analogue outputs, serial bus connections,
power supplies) must have reinforced or double insulation from the
mains network;
• in residential environments, the connection cable between the pCO
and the terminal must be shielded;
• there is no limit to the number of cables that can be connected to an
individual terminal. The only limitation concerns the maximum current
crossing each terminal: this must not exceed 8 A;
• the maximum size of wires connected to a terminal is 2.5 mm2 (12
AWG);
• the maximum value of the twisting torque to tighten the screw on the
terminal (torque tightening) is 0.6 Nm;
Warnings
• Installation must be performed according to the standards and
legislation in force in the country where the device is used;
• for safety reasons the equipment must be housed inside an electrical
panel, so that the only accessible part is the display and the keypad;
• in the event of malfunctions, do not attempt to repair the device, but
rather contact CAREL.
Anchoring the pCO
The pCO is installed on a DIN rail. To fasten the unit to the DIN rail, press it
lightly against the rail. The rear tabs will click into place, locking the unit
in place. Removing the unit is just as simple, using a screwdriver through
the release slot to lever and lift the tabs. These are kept in the locked
position by springs.
4.2 Power supply
pCO5 power supply (controller with
terminal connected)
28 to 36 Vdc +10/-20% and 24
Vac +10/-15% 50 to 60 Hz;

Maximum current P=11W, P=14VA, Imax=700mA
Tab. 4.a
• power supply voltage other than that specified will seriously damage
the system;
• a Class II safety transformer, rating 50VA, must be used in the installation
to supply just one pCO5 controller; the pCO5 compact on the other
requires the same type of transformer yet with a 25 VA rating.
• the power supply to the pCO controller and terminal (or pCO
controllers and terminals) should be separated from the power supply
to the other electrical devices (contactors and other electromechanical
components) inside the electrical panel;
• if the power transformer secondary is earthed, check that the earth
wire is connected to terminal G0. This applies to all the devices
connected to the pCO;
• if more than one pCO board is connected in a pLAN network, make sure
that the G and G0 references are observed (G0 must be maintained for
all boards);
• a yellow LED indicates that the pCO is powered.

4.3 Connecting the analogue inputs
The analogue inputs on the pCO can be configured for the most common
sensors on the market: NTC, PT1000, 0 to 1 V, 0 to 5 V ratiometric, 0 to 10
V, 0 to 20 mA, 4 to 20 mA.
Connecting active temperature and humidity probes
The pCO can be connected to all the CAREL DP* series active temperature
and humidity probes configured as 0 to 1 V or as 4 to 20 mA.
For temperature probes use the 4 to 20 mA or NTC configuration, as
the 0 to 1 Vdc signal is limited to the range 0 to 1 V and therefore is not
always compatible with the standard 10 mV/°C signal of CAREL probes
(for negative temperatures and temperatures above 100 °C a probe alarm
may be generated).
The inputs must be pre-configured for 0 to 1V or 4 to 20 mA signals in the
application program resident in the flash memory.

4.4 Fast digital inputs
On the pCO5 range (SMALL, MEDIUM, LARGE, EXTRALARGE) inputs B4
and B5 can be configured in the application as fast digital inputs. In
addition, input B5 can be enabled in the application to act as a counter.
In any case, the input must be connected to a voltage-free contact.
Important:
• the wires connecting the fast digital inputs must be shielded to avoid
causing electromagnetic disturbance in the probe cables;
• separate as much as possible (at least 3 cm) the probe and digital
input cables from the power cables to loads to avoid possible
electromagnetic disturbance. Never insert power cables (including the
electrical cables) and probe signal cables in the same conduits.
Connection diagram
The fast digital input can be used as a counter.The count is performed on
the negative edge of the pulse. The pulse generator device will have two
digital outputs with transistor optocoupler, which will be connected to
the inputs shown as in the figure..

4.5 Connecting the digital inputs
The pCO features digital inputs for connecting safety devices, alarms,
device status and remote switches. These inputs are all optically isolated
from the other terminals. They can work at 24 Vac, 24 Vdc and some at
230 Vac.
Note: separate as much as possible the probe signal and digital input
cables from the inductive load and power cables, to avoid possible
electromagnetic disturbance.
Important warning: if the control voltage is drawn in parallel with
a coil, fit a dedicated RC filter in parallel with the coil (typical ratings are
100 Ω, 0.5 μF, 630 V).
If connecting the digital inputs to safety systems (alarms), remember that:
the presence of voltage across the contact must be the normal operating
condition, while no voltage must represent an alarm situation. This will
ensure that any interruption (or disconnection) of the input will also be
signalled. Do not connect the neutral in place of an open digital input.
Always interrupt the phase. The 24 Vac or 28 to 36 Vdc digital inputs have
a resistance of around 5 kΩ.
24 Vac digital inputs
On the pCO5 all inputs can be 24 Vac.
The following figure represents one of the most common connection
diagrams for the 24 Vac digital inputs, referred to the pCO5

230 Vac digital inputs
PCO5 ONLY
There are up to two groups of inputs that can be powered at 230 Vac;
each group has two inputs. The groups feature double insulation
between them and can refer to different voltages. Within each group the
digital inputs are not independent, however: for example, with reference
to Fig. 4.o inputs ID15 and ID16, due to the common terminal, must be
powered at the same voltage to avoid dangerous short-circuits and/or
the powering of lower-voltage circuits at 230 Vac. In any case, the inputs
feature double insulation from the rest of the controller.
The following figure represents one of the most common connection
diagrams for the 230 Vac digital inputs.

Warnings for 230 Vac digital inputs:
• 230 Vac 50/60 Hz +10/-15 %;
• for each group, the two inputs — 24 Vac or 28 to 36 Vdc or 230 Vac — have
the same common pole, the inputs will both work at the same voltage
(24 Vac or 28 to 36 Vdc or 230 Vac) with basic insulation.
Remote connection of digital inputs
Important note: do not connect other devices to IDn.
The sizes of the cables for the remote connection of the digital inputs are
shown in the following table:

If the product is installed in industrial environments (application of EN
61000-6-2) the connections must be less than 30 m long.
This length shouldn’t be exceeded in any case, to avoid reading errors.
4.6 Connecting the analogue outputs
Connecting 0 to 10 V analogue outputs
The pCO5 provides 0 to 10 V optically-isolated analogue outputs,
powered externally at 24 Vac or 28 to 36 Vdc. Fig. 4.p below shows the
electrical connection diagram; the 0 V of the power supply is also the

Optional modules
Module for converting a PWM analogue output to a linear 0 to 10 V
and 4 to 20 mA analogue output
The module is used to convert a PWM output (5 V pulses) to a linear 0 to
10 V and 4 to 20 mA analogue output (code CONV0/10A0).
The control signal (at the input terminals optically-isolated from the rest
of the module) must have a maximum amplitude of 5V and a period
between 8 ms and 200 ms.The 0 to 10V output voltage can be connected
to a maximum load of 2 kΩ, with a maximum ripple of 100 mV, while the
4 to 20 mA current output can be connected to a maximum load of 280
Ω, with maximum overshoot of 0.3mA.
The module’s physical dimensions are 87x36x60 mm (2 DIN modules) and
has IP20 index of protection.
Module for converting a 0 to 10 V analogue output to an SPDT digital
output (code CONVONOFF0)
The module is used to convert a 0 to 10 V analogue output (Yn) to an
ON/OFF relay output. The control signal (at the input terminals, optically-
isolated from the rest of the module), to ensure the switching of the relay
from OFF to ON, must have a maximum amplitude of 3.3 V. The relay is
SPDT, with max current of 10 A and max inductive load of 1/3 HP. The
module’s physical dimensions are 87x36x60 mm (2 DIN modules) and has

The module is used to independently divide the frequency of two signals
by a factor of 8. The two input signals (at the input terminals, optically-
isolated from the rest of the module) must have a amplitude between
10 and 20V, a duration greater than 10 ms and a maximum frequency
of 10 Hz.
The module’s physical dimensions are 87x36x60 mm (2 DIN modules) and
has IP20 index of protection.

4.7 Connecting the digital outputs
The pCO features digital outputs with electromechanical relays. For ease
of installation, the common terminals of some of the relays have been
grouped together. If the following diagram is used (Fig. 4.p), the current
at the common terminals must not exceed the rating (nominal current)
of a single terminal (8A).

The relays are divided into groups, according to the insulation distance.
Inside each group, the relays have just basic insulation and thus must
have the same voltage (generally 24 V ac or 110 to 230 Vac). Between the
groups there is double insulation and thus the groups can have different
voltages. There is also double insulation from the rest of the controller.
Changeover outputs
Some relays feature changeover outputs:

pCO5 compact terminals 1
Tab. 4.o
Solid state relay (SSR) digital outputs
pCO5 The pCO also features a version with solid state relays (SSR) for
controlling devices that require an unlimited number of switching cycles
and thus would not be supported by electromechanical relays. These
outputs are dedicated are dedicated to loads powered at 24 Vac or 28 to
36 Vdc with maximum power Pmax= 10 W.
These three fundamental rules should be adopted in pCO applications
with SSR outputs:
1. only control resistive loads with a maximum power of 10 W;
2. to control inductive loads use an additional external SSR;
3. for AC power supply to resistive loads or external SSRs, use the same
power supply as the pCO (connected to terminals G/G0), which
as always must be specified, dedicated and not in common with
the power supply to other devices on the electrical panel (such as
contactors, coils, etc…)

5. PLAN NETWORK CONFIGURATION
Each terminal associated with a board can be defined as:
— private (“Pr”) if it exclusively displays the output of that board;
— shared (“Sh”) if either automatically or from the keypad it can be switched
between various boards;
— shared with printer (“Sp”) if, as well as being be shared it’s fitted with an
RS232 serial card connecting a printer (valid only for the old PCOT and
PCOI terminals, not the pGD).
Each pCO constantly updates the display on the private terminals, while
the shared terminals are only updated only if the pCO in question has
control over the terminal at that moment.
5.1 Introduction
All pCO controllers can be connected together and to other CAREL
devices in a pLAN local network, without requiring optional devices,
allowing the communication of data and information from one location
(node) to another.
The pCO terminals can show the variables (temperature, humidity,
pressure, I/O, alarms) from just one controller at a time. The terminal
does not need to be connected to the pCO during normal operation,
but rather can be used just for initial programming of the fundamental
parameters.
one or more terminals are disconnected or malfunctioning, the control
program continues to function correctly on each pCO board.
Generally, the application program can monitor the status of the network
and intervene as a consequence to ensure the continuity of the control
functions.

The standard communication speed over the network is 62500 bps; some
devices also support speeds of 115200 bps.
All units in the network must however be set with the same speed.
A maximum of 32 units can be connected, including:
— pCO controllers that run the control program;
— boards that extend the I/O functions (such as the EVDevo driver);
— terminals (8×22).
Each unit in the pLAN is identified by a unique address, i.e. a number
between 1 and 32. The latter (32) can only be assigned to a terminal.
Programs for different applications (e.g.: standard chiller, standard air-
conditioners, compressor rack, …) cannot automatically be integrated
into a local network: they must be configured considering the system
architecture using the Carel development tool.
Each pCO board connected to the network can manage a series of
terminals at the same time. The values are displayed on the terminals
simultaneously and not independently, as if the keypads and display were
connected in parallel: for this reason, the pCO cannot control different
types of terminals at the same time.

IIn this example the shared terminal is associated with 4 pCOC controllers
however at this instant only controller 1 can display data and receive
controls from the keypad.
Switching between controllers occurs is cyclical (12341…)
and is done by pressing a button defined by the application program,
however it can also be managed automatically when set by the program:
for example, a pCO may request control of the shared terminal to display
alarms or, vice-versa, relinquish control to the next pCO after a set time
(cyclical rotation).
The data corresponding to the number and type of terminals are
established in the initial network configuration phase, saving them to
the permanent memory on each individual pCO controller. Details of
the configuration procedure are described below. The pLAN connection
between two pCO controllers is performed only using a AWG20/22
shielded cable made up of twisted pair plus shield. Connection between
a terminal and a pCO can be performed using a 6-wire telephone cable or
AWG20/22 shielded cable, depending on the model of terminal.
Further details on installation of the terminals are provided in the section
on“pLAN electrical connections”.

ENG
“pCO5”+0300009EN rel. 1.2 — 24.04.2014
5.2 pGDE/pGD1 terminal installation
Connection between the terminal and the pCO is made using a 6-wire
telephone cable supplied by CAREL (code S90CONN).
To make the connection simply plug the telephone connector into the
RJ12 jack on the rear of the terminal and connector:
• J10 on pCO5;
• J14 on pCO5 compact.
The address of the terminal can be set in the range from 0 to 32; addresses
between 1 and 32 are used by the pLAN protocol, while address 0
identifies the Local terminal protocol, used for non-graphic point-to-
point connections and to configure the pCO. The default address is 32.
The address of the terminal can only be set after having powered the
terminal via the RJ12 connector. To access configuration mode press UP,
DOWN and ENTER (,,  ) together for at least 5 seconds; terminal will
display a screen similar to the one shown below, with the cursor flashing
in the top left corner:
Fig. 5.c
To modify the address of the terminal (“Display address setting”) carry out
the following operations in sequence.
Press ENTER once: the cursor will move to the “Display address setting”
field.
Select the desired value using the UP and DOWN buttons, and confirm
by pressing ENTER again.
If the value selected is different from the value saved, the following screen
will be displayed and the new value will be saved to the permanent
memory on the display.
Fig. 5.d
If the address field is set to 0, the terminal communicates with the pCO
board using the Local terminal protocol and the“I/O Board address”field
disappears, as it no longer has any meaning. To modify the list of the
terminals (private and shared) associated with a pCO board, carry out the
following operations in sequence:
• enter configuration mode (see above) pressing the UP, DOWN and
ENTER buttons together for at least 5 seconds.
• press ENTER twice: the cursor will move to the“I/O Board address”field.
• select the address of the pCO board in question and confirm by
pressing ENTER.
Then the pCO will start the configuration procedure, opening a screen
similar to the following.
Fig. 5.e
1. Press ENTER again: the configuration screen will be shown, similar to
the one below.
Fig. 5.f
Configure the terminals as desired. ENTER moves the cursor from one
field to the next, while UP and DOWN change the value of the current
field.
P:xx displays the address of the selected pCO board (in the example in the
figure this is board 1).
To exit the configuration procedure and save the data, select “Ok?”, set
“Yes”and confirm by pressing ENTER.
During the configuration procedure, if the terminal remains inactive (no
button is pressed) for more than 30 seconds, the pCO board automatically
interrupts the procedure without saving any changes.
Important: the pGD* terminals cannot be configured as “Sp”
(shared with printer) as they have no printer output. Selecting this mode
has no effect on management of the messages to be printed.
if during operation the terminal detects inactivity on the pCO board it
is connected to, the display is cleared and a message similar to the one
shown below is displayed:
Fig. 5.g
If the terminal detects inactivity of the entire pLAN network, that is, it does
not receive any messages from the network for 10 seconds consecutively,
the display is cleared completely and the following message is shown:

5.3 pLAN address configuration on pCO5
and pCO5 compact
On the pCO5 range (SMALL, MEDIUM, LARGE, EXTRALARGE) the
controller’s pLAN address can be assigned in two different ways:
1. using the new function for pCO5 with special button and display
with two 7 segment LEDs;
2. using the built-in or external terminal (e.g. pGD1).
The default pLAN address setting of the pCO5 programmable controller
is 1 and it’s assigned to the private terminal with address 32.
Setting by button and display (only applies to pCO5)
The special button (A) is located on the left of the display. To access it use
the tip of a screwdriver (diam. <3mm).
Displaying the pLAN address
Procedure:
• press button A briefly (no more than 5 s) to display the controller’s
current pLAN address. Five seconds after releasing the button the
display is cleared.

5.4 pLAN electrical connections on the pCO
Connection between pCO boards in a pLAN is carried out exclusively using AWG20/22 shielded, twisted pair cable, with capacitance between the wires
less than 90 PF/m.
Maximum pLAN network length: 500 m with AWG22 shielded twisted pair cable.
The boards are connected in parallel, with connector J11 as the reference.
IMPORTANT: observe the network polarity: RX/TX+ on one board must be connected to RX/TX+ on the other boards; the same is true for RX/TX-.
The following figure shows a diagram of a number of boards connected in a pLAN network and powered by the same transformer, typical for a number of
boards connected inside the same electrical panel.

5.5 Remote terminal with pLAN network
When pCO boards are connected in a pLAN network, the terminal can be
remotely-installed at a distance of up to 50 metres, if using a telephone
cable, while it can be located at a distance of up to 500 metres if using a
shielded twisted pair, TCONN6J000 and a separate power supply.
Note: to reach the maximum length use a bus layout with branches not
exceeding 5 m.
The figures below show the connection diagrams for the various
configurations.
If the terminal is used in residential environments the cable always must
be shielded.
The maximum distance between pCO and user terminal is shown in the
following table:
type of cable power supply
distance
power supply
telephone 10 m taken from pCO (150 mA)
AWG24 shielded cable 200 m taken from pCO (150 mA)

Important: the overall length of the network must not exceed the
500 m. Consequently if the terminal is installed remotely the terminal
cable length must be included in the total length.
Important: the terminal cable represents a branch of the network,
therefore if it’s more than 5 m long it can only be connected to the first or
last pCO in the network.

SERIAL CONNECTIONS
6.1 pCO5
serial connections: differences
compared to pCO3
Compared to the pCO3, pCO5 boards have a second serial port
(BMS2) on connector J25 and a second FieldBus port on connector
J26 (FBus2). pCO5 Large and Extralarge boards still have connector J23
which is marked as FBus2 in the same way as connector J26. As regards
management from the 1Tool application, this is in fact the same serial
port and different addresses must be used for the devices connected
to both connectors, while from an electrical point of view the ports are
independent (an electrical fault on port J26 does not affect port J23).

pCO5
serial connections
pCO5 features three types of serial connections: pLAN, FieldBus, BMS.
The RS485 Fieldbus serial port has Master hardware, while the RS485 BMS
serial port has Slave hardware. The protocols used on the RS485 Fieldbus
port are, due to the nature of the port, Master protocols (Carel Master or
Modbus RTU Master), even if in special cases Slave protocols can be used
(Carel Slave or Modbus RTU Slave), adopting the due measures. Similarly,
Slave protocols are used on the RS485 BMS port, even if again adopting
the due measures Master protocols can be used.

Important warnings
• a serial port with Master hardware (FB) provides the network, via a
suitable impedance, the correct polarisation voltage required for
operation of all the connected devices: the master itself and its slaves;
• serial ports with Slave hardware (BMS), on the other hand, do not
feature polarisation voltage, hence it’s always recommended to
connect at least one device with Master hardware (FB) to the network
so that this is correctly polarised;
• however it’s not possible to connect more than two Master hardware
devices (FB) to the same network as the total polarisation impedance
of the network would be too low, and thus not able to supply the right
voltage for the RS485 network;
• it’s recommended to connect serial probes or other devices that are
wired to the electrical panel to serial TWO – FieldBus 1, so as to exploit
the disturbance filtering property of the optically-isolated card.

Note: for Master – Slave networks the max length allowed is 1000
m; the 120Ω 1/4W terminating resistors on the first and last device in
the network should be used when the length exceeds 100 m.
Special cases
• For networks made up only of devices with slave HW, a maximum of
207 devices can be connected. The max network length allowed is 100
m. DO NOT connect the 120Ω 1/4W terminating resistors on the first
and last device;
• for networks made up only of devices with master HW, a maximum 2
devices can be connected. The max network length allowed is 1000 m.
The 120Ω 1/4W terminating resistor on the first and last device in the
