1. INTRODUCTION

c.pCO is a microprocessor-based, programmable electronic controller, featuring a multitasking operating system, compatible with the c.pCO

Sistema family of devices, which includes programmable controllers, user terminals, gateways, communication devices and remote management devices. These devices represent a powerful control system that can be easily interfaced with most Building Management Systems (BMS) available on the market. The controller has been developed by CAREL to provide solutions for several applications in air-conditioning, refrigeration and

HVAC/R in general. Its fl exibility allows for creation of tailor made control solutions according to customer specifi cations. Compared to pCO sistema, the range is enhanced by a new compact controller, and consequently comprises the c.pCOmini (4 DIN module and panel mounting version), featuring 10 universal inputs/outputs and available with built-in driver for single-pole electronic expansion valve, as well as the c.pCO Small, Medium,

Large, ExtraLarge models. The number of inputs/outputs can be increased by connecting a c.pCOe expansion board.

Medium size controllers can feature also one or two built-in drivers for electronic expansion valves. The Ultracap module (accessory) can be used as an emergency power supply for valve drivers, so as to ensure total closure of the valves in case of power failures (alternating current).

c.pCO can be connected in an Ethernet LAN to other c.pCO family controllers. Each device in the LAN can exchange digital or analogue variables with all the others, based on the application program used. c.pCO can also be connected via a pLAN (pCO Local Area Network) to the pGD range of terminals.

Each Fieldbus serial port, whether built into the controller or installed via an optional card, can be connected to controlled fi eld devices such as valve and damper actuators and external drivers (e.g. drivers for electronic expansion valves, EVD Evolution).

Each BMS serial port, whether built into the controller or installed via an optional card, can be connected to fi eld-level, automation-level or management-level standard bus systems, such as Konnex®, LON®,

BACnet™, etc.

The real-time operating system (OS) manages priorities so as to ensure the application program cycle time, 32-bit data and fl oating point numbers, and the Ethernet multimaster and multi-protocol connection.

Main features:

• optimization of the memory occupied by the Operating System and the application program, of the boot time, of the time for loading the application program and of the cycle time;

• system response time optimization: the controller executes several processes in parallel, each managed with a diff erent priority;

• independent processes: each process, whether a protocol, USB port management, data and alarm log (datalogger), data exchange with tERA cloud service, works independently of the others;

• runtime debug (on target)

• native management of TCP/IP multitasking protocol

Local connectivity:

• built-in web server, completely customisable, supports HTML standard and JavaScript. The 90 Mbyte memory can be used to store pages created using the most common website development tools. Dynamic methods (CGI, Common Gateway Interface) are available to read and write the application program variables. Other innovative functions include: the possibility to display the contents of the pGD1 terminal in the browser, display graphs of data recorded by the datalogger and plot data from probes and energy meters in real time (variable trends);

• fi le server (FTP): the c.pCO public fi le system can be accessed in the local network via FTP. Consequently, an FTP client can be used to connect to the controller so as to upload updates, web pages and documents. The “.csv” (comma separated value) fi les exported by the datalogger can be downloaded

• creation of accounts with diff erent access privileges, associated to both a webserver and an FTP server;

• management of multiple simultaneous instances of Modbus TCP/IP

Master and Slave protocol;

• management of BACnet™ protocol with B-BC profi le (MSTP or TCP/IP, license to be purchased separately).

Remote connectivity:

• integrated connectivity to the Carel tERA cloud service: by connecting a normal router to the controller, a secure connection can be established to the tERA server. Remote services can be activated for the management of control variables, alarm notifi cation, data analysis and reports. The connections are encrypted using the SSL (Secure Socket Layer) standard, in compliance with NIST, international reference for information security over the internet.

• a fi rewall guarantees remote access only via a secure connection (tERA cloud connection or encrypted VPN)

Integrated USB peripheral: it can be used to update the controller and save web pages, documents and applications in the fl ash memory. Also used to download the logs from the controller.

• c.pCO Small...Extralarge: the host and device USB ports are managed directly by the operating system. USB host (top): a USB fl ash drive can be used to load updates (operating system/application program) on the controller. USB device port (bottom): by connecting c.pCO to a personal computer, its memory is made available as a removable drive, and at the same time a communication channel is established with the c.suite software for programming and online debugging.

• c.pCOmini: the 2 USB ports are physically integrated into a single micro

USB port; the same performance is available as for the two ports on the larger models.

Other features:

• the same controller can be connected to up to 3 pGD1/pGDE terminals;

• external or built-in terminal with display and keypad with LED backlit buttons, can be used for uploading software and commissioning;

• universal inputs/outputs confi gurable via an application program, for connecting active and passive probes, digital inputs, analogue and PWM outputs. This extends the possibilities of confi guring inputs/outputs without having to install a larger controller;

• possibility to use the c.suite software development environment, installable on a personal computer, for creating and customising the application program, simulating operation, supervising performance and confi guring the Ethernet network;

• wide range of models that diff er in terms of:

• size (mini, Small, Medium, Large and Extralarge), to ensure maximum fl exibility according to the application;

• digital outputs (24/230 V relay) and SSR (solid state relay);

• NO or NC relay outputs

• integrated optically-isolated/not optically-isolated serial ports;

• optional built-in display;

• various types of connectors (spring, screw, etc.).

Software programming suite, c.suite: designed as a set of independent modules, one for each phase in HVAC/R software development, c.suite allows teams of professionals with diff erent skills to work in a group on based on workfl ow. All the software modules cooperate with each other based on centralised data exchange, optionally managed by a software version number (SVN):

• c.strategy: environment where expert algorithm programmers prepare the core of the application program. Features of the programming environment:

- total independence of programming logic from the hardware and the connected devices;

- availability of IEC 61131 standard languages: ST (structured text), FBD

(function block diagram), SFC (sequential function chart), LD (Ladder diagram), which can also be used simultaneously;

- datatype management: 32-bit, fl oating point, array and native structures;

- debug on target via USB port or Ethernet;

• c.mask: dedicated environment for developers of the user interface.

• c.design: defi nition of confi gurations, such as controller type and size, type of inputs/outputs, master/slave protocols, default parameter values, datalogger, network address and user management, connection to tERA cloud services.

• c.factory: used to program the controller, loading the application program and the appropriate unit confi guration during assembly.

Applications

When provided with a dedicated application program, the controller can be used to control diff erent kinds of equipment:

• chillers and heat pumps;

• roof-top units;

• air-conditioners;

• small/medium-sized air handling units (on request);

• refrigerated showcases (on request and to specifi cations);

• cold rooms (on request and to specifi cations);

• curing rooms;

• compressor racks;

• universal stage controllers.

1.1 Functional layout

The fi gure below shows the functional layout of an air handling unit. Damper actuators and valve actuators are fi eld devices that communicate through

Fieldbus 1 (ref. C). Fieldbus 2 (ref. E) is the medium through which the serial probes communicate the values measured, and through which the humidifi er control board and the fans exchange data and receive set points from the controller. The built-in terminal and the remote terminal, which communicate via pLAN (ref. A), are used for installing the application program and for commissioning the system.

The PGD touchscreen terminal, intuitive and simple to use, can be used while the unit is normally working to set switch-on and switch-off times, to enter the main parameters, to perform other advanced functions of the application program and to view any alarms triggered. In this case data are exchanged via Ethernet port (ref.

D). In the same network it is possible to connect another c.pCO controller as well as to communicate with remote cloud service tEra or to BACnet™ supervisor. The system can be connected to other supervision systems (Konnex®, LON®, etc.) after installing the relative BMS1 expansion card (ref. B). pGD1 pGD terminal touch screen

Module

Ultracap for c.pCO built-in driver

Notes

In case of power failures the module ensures a temporary power supply for the driver only, for the time necessary to immediately close the electronic valves connected (one or two). This avoids having to install a solenoid valve or backup battery kit in the refrigerant circuit.

Module Ultracap external

This module, mounted on a DIN rail, can be used as alternative to the Ultracap module (PCO-

S00UC20). It can also be used in applications with a controller without built-in driver for electronic expansion valves (e.g. pCO Small + EVD Evolution + external Ultracap module). If used with c.pCOmini, the module ensures a temporary power supply for the driver only, for the time necessary to close the electronic valve (see technical leafl et +0500058IE)

Driver for electronic expansion valve

The driver for electronic expansion valves with two-pole stepper motor is a controller that manages refrigerant expansion in a refrigerant circuit. With the c.pCO family controllers, the version with Modbus/Carel RS485 serial port is required. Alternatively, the driver can work in stand-alone mode.

Humidifi cation board

KUE CAREL

Used to manage an immersed electrode humidifi er and share the main parameters across a

CAREL/Modbus RS485 serial line. Equipped with:

• all the inputs and outputs required to completely and independently control the humidifi er;

• three LEDs to indicate: alarms (red), steam production (yellow), 24 Vac power supply (green);

• can be connected to the CPY terminal (CPYTERM*) or to the supervisor network with Modbus®

RTU or CAREL proprietary protocol.

Interface for OEM series humidifi ers

Used to control the main parameters on CAREL OEM humidifi ers directly from the c.pCO controller. The values measured by the sensors (high level, supply water conductivity, power consumption sensor) are converted into signals that are compatible with the inputs on the controller.

Connection via serial ports:

A master/slave network of c.pCO controllers can be created by using the

RS485 serial ports. Such networks comprise:

• one c.pCO controller (Master) that communicates via the Fieldbus

RS485 serial port using Carel Master or Modbus Master protocol;

• one or more c.pCO controllers (Slaves) connected to the point-to-point network via the BMS RS485 serial port using Carel Slave or Modbus

Slave protocol.

MASTER - SLAVE network

The c.pCO Small...Extralarge controllers have two 10/100 Mbps/s Ethernet ports. These two ports are connected internally via a switch that automatically controller is not powered, pass-through between the two ports will be interrupted. The two ports feature auto crossover (Auto-MDIX). The c.pCOmini

High End controller features one 10/100Mbps/s Ethernet port.

3.3 Controller network connections

Multimaster or Master/Slave networks of c.pCO controllers can be created using the Ethernet ports and the serial ports:

Connection via Ethernet port

The built-in Ethernet ports on the c.pCO can be used to create multimaster and multiprotocol networks, with transmission speeds up to 100 Mbps.

The controllers can be connected together via an external switch (see the fi gure below). For c.pCO Small...Extralarge models, the two Ethernet ports are connected by an internal hub-switch, meaning a daisy-chain network can be created without needing an external switch (see fi gure 3.c).

Important warnings:

1.

By applying appropriate impedance, a serial port with Master hardware (FBus) supplies the network with the bias voltage required to run all the connected devices, i.e. the master itself and its slaves; conversely, serial ports with slave hardware (BMS) do not provide bias voltage, so it is always advisable to connect at least one device with master hardware (FBus) to the network so that it is correctly biased;

2.

However, no more than two devices with master hardware (FBus) can be connected to the same network, otherwise the network total bias impedance becomes too small and incapable of supplying the required voltage to the RS485 network.

3.

It is recommended to connect the serial probes or other fi eld devices to an optically-isolated version of the Fieldbus serial port or to serial port TWO – Fieldbus 1 to exploit the fi ltering properties of optical isolation.

Special cases

•

In networks consisting only of Master HW devices, no more than 2 devices can be connected. The max. length allowed for the network is 1000 m. If the network is longer than 100 m, apply the 120Ω, 1/4W terminating resistors to the fi rst and last devices in the network;

• connect the computer to a network with no more than 1 master HW device or no more than 207 slave HW devices.

Note:

• for correct assembly, follow the instructions shown in the following diagram.

•

Important: when assembling, make sure that the frame is securely in place on all four sides.

• if needing to remove the frame, use a screwdriver to lever it off in slot C.

• to access the USB port, open the cover B and lift the rubber cap A using the tab

• before closing the cover B again, make sure the rubber cap A is properly inserted (it must be flush with the outer plastic surface).

• if needing to cut sheet metal, it is recommended to use laser cutting;

• the thickness of the sheet metal or the material used to make the electrical panel must be suitable to ensure safe and stable installation of the terminal;

• the tension applied by the screws must not cause deformation of the sheet metal, so as to not compromise the degree of protection (IP) shown in the specifications. This degree of protection is guaranteed in the following conditions: maximum deviation of rectangular opening from flat surface ≤ 0.3mm, maximum roughness of the surface where the gasket is applied ≤ 120

Pm.

Fig. 4.b oxidation;

• exposure to dust (formation of a corrosive patina with possible oxidation and reduced insulation);

• exposure to water.

Positioning the controller inside the electrical panel

Install the controller inside an electrical panel in a position where it cannot be reached and it is protected from knocks or impact. The controller should be placed inside the panel in a position where it is physically separated from power components (solenoids, contactors, actuators, inverters, etc.) and their respective cables. The ideal solution is to house these two circuits in two separate cabinets. Proximity to such devices/cables may cause random malfunctions that are not immediately evident. The panel casing must allow an adequate fl ow of cooling air.

4.2 Installation

Environmental conditions

Avoid installing the controller and the terminal in places with:

• exposure to direct sunlight and to the elements in general;

• temperature and humidity outside the product operating range (see chapter 12, “Technical Specifi cations”);

• large, rapid fl uctuations in room temperature;

• strong magnetic and/or radio frequency interference (avoid installing near transmitting antennas);

• strong vibrations or knocks;

• presence of explosives or fl ammable gas mixtures;

• exposure to aggressive and polluting atmospheres (e.g. sulphur and ammonia vapours, salt mist, fumes) that can cause corrosion and/or

Important:

• for safety reasons the controller should be installed inside an electrical panel so that the only accessible parts are the display and the built-in terminal keypad;

• install the controller so that the disconnect devices can be used safely and without hindrance.

• when laying out the wiring, separate as much as possible the probe cables, digital input cables and serial line cables from the power cables, contactors, thermomagnetic devices, in order to avoid electromagnetic interference;

• never run power cables and probe signal cables in the same conduits

(including the ones in the electrical panels);

• for control signals, use shielded cables with twisted wires. If the control cables have to cross over power cables, the intersections should be as close as possible to 90 degrees; under no circumstances should the control cables be laid parallel to the power cables;

• keep the paths of the probe cables as short as possible and avoid making spiral paths that enclose power devices;

• in case of malfunctions do not attempt to repair the device, but contact a CAREL service centre.

Electrical installation

Important: before servicing the equipment, disconnect the controller from the power mains by moving the system main switch to OFF.

Make sure the system is provided with a power disconnector conforming to regulations. Use cable lugs that are suitable for the terminals used. Loosen each screw and insert the cable lugs, then tighten the screws. There is no limit to the number of wires that can be connected to each individual terminal. When tightening the terminal screws apply a tightening torque no greater than 0.6

Nm. For information on the maximum allowable length of the connections to the analogue/digital inputs and to the analogue outputs please refer to the “Technical Specifi cations” (chapter 12). In environments subject to strong disturbance use shielded cables with the braiding bonded to the earthing conductor in the electrical panel. After making the connection, gently tug on

Note: see the technical leafl ets for the cards being installed.

See the technical leafl et +0500059IE.

Ultracap module installation

See the technical leafl ets +0500042IE and +0500041IE.

Note:

• secure the cables connected to the controller with clamps placed at

3cm from the connectors;

• if the power transformer secondary winding is earthed, make sure the earth conductor is bonded to the conductor that goes to the controller and is connected to terminal G0. This applies to all the devices connected to the controller through a serial network.

Ethernet network

Connections:

• use CAT-5 STP shielded cables;

• always make the earth connection using the male spade near the

Ethernet connectors;

• the maximum length of an Ethernet connection is 100 m between consecutive devices max 100 m max 100 m max 100 m

Important:

• using a supply voltage other than specifi ed can seriously damage the system;

• connect the fuse close to the controller;

• the controller should only be installed, serviced and inspected be qualifi ed personnel and in compliance with national and local regulations;

• all the extra low voltage connections (24 Vac/Vdc or 28 to 36 Vdc analogue and digital inputs, analogue outputs, serial bus connections, power supplies) must have reinforced or double insulation from the power mains;

• avoid touching or nearly touching the electronic components mounted on the boards to avoid electrostatic discharges from the operator to the components, which may cause considerable damage;

• do not press the screwdriver on the connectors with excessive force, to avoid damaging the controller;

• using the device in any way other than specifi ed by the manufacturer can compromise its protection;

• use only optional boards and connectors supplied by Carel.

RS485 network

To improve the controller immunity against electromagnetic interference, the serial connection cable should be a shielded twisted pair cable,

2-wire or 3-wire depending on the isolation of the serial connection. The following rule applies:

• if the serial port is isolated (functionally) from the power supply, a third wire is required in the serial cable to act as a common reference for the controllers. If the serial port is not optically isolated and the common reference is already present, no third wire is required.

For the RS485 network, use a twisted pair cable with the specifi cations shown in the table.

The controller and the terminal are connected to a pLAN network.

1: Connecting the terminal to one c.pCO controller

When connecting the controller to the terminal, the following restrictions should be kept in mind:

1. the overall length of the pLAN network should not exceed 500 m.

Consequently, if the terminal is installed in a remote position, the length of the terminal cable must be included in the total length;

2. the unshielded telephone cable can be used for a max. length of

50 m. Beyond this length, use a 3-wire shielded cable (see the table below);

3. for lengths greater than 200 m, the power supply for the terminal must be provided separately;

4. no more than 3 terminals can be connected to the same c.pCO controller. The terminals must be the same type (e.g. all pGD1).

One terminal is powered by the controller, and the other two by an external power supply.

Important:

• in domestic installations, standard EN55014 requires the connection cable between the controller and the terminal to be shielded, with the shield earthed at both ends;

• in industrial installations with length >10 m, the connection cable between the controller and the terminal must be shielded and the shield must be earthed.

Case A: 1 terminal.

A.1: distance L < 50 m.

The typical connection for one terminal (e.g. PGD1) is made using a 6-wire telephone cable available from CAREL as an accessory (S90CONN00*).

The telephone connector provides both data transmission and the power supply for the terminal.

To make the connection:

• plug the connector into terminal J10 until it clicks into place.

To remove the connector:

• press lightly on the plastic catch on the connector and pull it out.

A.2: distance 50< L< 200 m.

Lengths greater than 50 m require two TCONN6J000 cards connected with a 4-wire shielded cable, as shown in the fi gure. The terminal is powered by the controller.

The terminal must be powered by an external power supply. Connect a 3-wire shielded cable to the pLAN connector (J11). Provide a separate power supply for the TCONN6J000 card, as shown in the fi gure.

2: Shared terminal connection in pLAN network

To share a terminal between several c.pCO controllers, these can be connected in a pLAN network, and the terminal connected to one of the controllers in the network (see the fi gure below). The previous details on the maximum length allowed between terminal and controller also apply in this case.

Case C: 3 terminals.

For the fi rst 2 terminals refer to Case B. For the third terminal use one of connections A.1, A.2 or A.3.

Important:

• the 24 Vdc at +Vterm (J24) can be used only in alternative to connector

J10 to power an external terminal, with maximum current 1.5 W;

• in networks with a star layout, if the cable is longer than 5 m, connect the terminal only to the fi rst or last c.pCO in the network (to avoid branches).

Important:

• power the c.pCO built-in driver with AC voltage only, with the transformer secondary winding earthed;

• if the Ethernet connection is featured and used, the transformer secondary must be earthed;

• using a supply voltage other than specifi ed can seriously damage the controller;

• if the transformer secondary is earthed, make sure that the earth conductor is connected to terminal G0. This applies to all the devices connected to the c.pCO through a serial network;

• if more than one c.pCO board is connected to a pLAN network, make sure that the G and G0 references are observed (G0 must be maintained for all controllers);

• the power supply to the controller(s) and the terminal(s) should be kept separate from the power supply to the other electrical devices

(contactors and other electromechanical components) inside the electrical panel.

Note:

• when the controller is powered, the yellow LED lights up;

• refer to the diagrams in par. 4.4 in case of controllers connected to a pLAN network and installed in the same electrical panel or in separate panels.

Universal inputs/outputs are distinguished by the letter U...

They can be confi gured from the application program for many diff erent uses, such as the following:

• passive temperature probes: NTC, PTC, PT100, PT500, PT1000;

• active pressure/temperature/humidity probes;

• ratiometric pressure probes;

• current inputs, 0 to 20 mA or 4 to 20 mA;

• voltage inputs, 0 to 1 Vdc or 0 to 10 Vdc;

• voltage-free contact digital inputs and fast digital inputs;

• analogue outputs, 0 to 10 Vdc;

•

PWM outputs.

Important:

• the universal inputs/outputs must be pre-confi gured to handle their respective signals from the application program;

• the universal inputs/outputs cannot be used as digital outputs.

Max. number of connectable analogue inputs

The maximum number of analogue inputs that can be connected to the universal inputs/outputs depends on the type used.

Note: the table shows the maximum number of inputs that can be connected. For example, it is possible to connect to a Small size controller a maximum of fi ve 0 to 1Vdc inputs related to probes powered by the controller, and a a maximum of fi ve 0 to 1 Vdc inputs related to probes powered externally. In any case, maximum number of 0 to 1Vdc inputs must be 5.

Important:

• if the controller is installed in an industrial environment (standard

EN 61000-6-2) the connections must be less than 10 m long; do not exceed this length to avoid measurement errors.

• to avoid electromagnetic interference, keep the probe and digital input cables separate from the power cables as much as possible (at least 3 cm). Never run power cables and probe signal cables in the same conduits (including the ones in the electrical panels).

Connecting active temperature and humidity probes

For information on the maximum number of probes that can be connected see the table at the beginning of this paragraph. The number depends on the power supply used. The distinction is between probes powered by the controller (terminal +VDC) and probes powered by an external source, and also between active probes with voltage or current outputs. For details on the operating range see the data sheets supplied with the probes. The controller can be connected to all the CAREL DP* series active temperature and humidity probes confi gured for 0 to 1 V or 4 to 20 mA.

Note: in c.pCOmini models it is not possible to manage 0 to 1 Vdc or 0 to 10 Vdc signals coming from probes powered directy by the controller.

Important: for temperature probes use the 4 to 20 mA or NTC confi guration, cause 0 to 1 Vdc signal is limited to the 0 to 1 V range and is therefore not always compatible with the standard 10 mV/°C signal of

CAREL probes (at temperatures below 0 °C or above 100 °C a probe alarm may be activated).

Important: the maximum current allowed on the digital input is 10 mA. Therefore the rating of the external contact must be at least 10 mA.

Connecting 0 to 5 V ratiometric pressure probes

For information on the maximum number of probes that can be connected see the table at the beginning of this paragraph. For details on the operating range see the probe data sheets. The controller can be connected to all CAREL SPKT series active pressure probes or any commercially available pressure probes with 0 to 5 V ratiometric signals.

Important:

• ratiometric probes are powered by the controller via terminal +5 VREF;

• ratiometric probes cannot be powered by an external source.

The fast digital input can be used as a frequency meter. The count is performed on the rising edge of the pulse. The pulse generator device will have one digital output with transistor optocoupler, which will be connected to the input as shown in the fi gure. For details on the input signal see the Technical Specifi cations table (see chap. 12).

Note: the application program shows the frequency values using specifi c variables. If the inputs are confi gured as counters, the counter is reset by the application program.

Example: input t

The controller features digital inputs for connecting safety devices, alarms, device status indicators and remote switches. See the table of technical specifi cations for the maximum cable length cables (see chap. 12).

These inputs are all optically isolated from the other terminals. They can work at 24 Vac (+10/-15%) or 28 to 36 Vdc (-20/+10%) (indicated as ID*), and some at 230 Vac (indicated as IDH*), see as reference fi gure below.

Note:

• if the control voltage is drawn in parallel with a coil, install a dedicated

RC fi lter in parallel with the coil (typical ratings are 100 Ω, 0.5 μF, 630 V);

• if the digital inputs are connected to safety systems (alarms), the presence of voltage across the contact should be taken as the normal operating condition, while no voltage represents 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.

Important:

• to avoid electromagnetic interference, keep the probe and digital input cables separate from the power cables as much as possible (at least 3 cm). Never run power cables and probe signal cables in the same conduits (including the ones in the electrical panels.

24 Vac digital inputs (c.pCO Small... Extralarge only)

Digital inputs ID... can be controlled at 24 Vac.

Note:

• the digital inputs are only functionally isolated from the rest of the controller;

• to keep the digital inputs optically isolated a separate power supply is needed for each input;

• the digital inputs can be powered at a diff erent voltage from the rest of the controller.

Cable cross-section

For remote connections to the digital inputs (length <50 m), use cables with a cross-section = 0.25 (mm 2 )

Important: If the controller is installed in an industrial environment

(standard EN 61000-6-2) the connections must be less than 30 m long. Do not exceed this length to avoid measurement errors.

230 Vac digital inputs (c.pCO Medium...Extralarge only)

Medium and Extralarge models feature one group of 230 Vac inputs

(terminal J8), while Large models have two groups (on terminals J8 and

J19). Each group consists of two digital inputs that can be powered at 230

Vac, indicated as IDH*, and two inputs that can be powered at 24 Vac/Vdc, indicated as ID*. The two groups of 230 Vac inputs have double insulation between each other and between them and the controller. The digital inputs connected may be the 24 Vac/dc inputs from one group and the

230 Vac inputs from the other. The two inputs of each group have the same common pole. Functional insulation is provided. In each group, the digital inputs must be powered at the same voltage (24 Vac, 28 to 36

Vdc or 230 Vac) in order to avoid dangerous short-circuits and/or the risk of powering lower-voltage circuits at 230 Vac

Note:

• the range of uncertainty of the switching threshold is from 43 to 90 Vac;

• the voltage must be 230 Vac (+10/-15%), 50/60 Hz.

V analogue outputs, to be powered externally at the same voltage as the controller, i.e. 24 Vac or 28 to 36 Vdc. The connection diagram is shown in the fi gure below. The 0 V supply voltage is also the voltage reference of the outputs. See the Technical Specifi cations table for details on the output current, output impedance, etc. (see chap. 12).

Note:

• the analogue output can be connected to the CONVONOFF0 module to convert the 0 to 10 V output into an ON/OFF relay output;

• a 0 to 10 Vdc analogue output can be connected in parallel to other outputs of the same type, or alternatively to an external voltage source. The higher voltage will be considered. Correct operation is not guaranteed if actuators with voltage inputs are connected;

• if optical isolation is not required, the VG-VG0 analogue outputs can be powered at the same voltage on G-G0: connect G0 to VG0 and G to VG.

5.5 Connecting the Ultracap module

The Ultracap module can be connected to power the controllers in the event of blackouts:

1. c.pCOmini controller: the module guarantees temporary power to the controller and driver for enough time to close the electronic valve (40s with forced closing of the valve, 60s without forced closing of the valve). NB: with Vdc power supply, forced closing of the electronic expansion valve is not managed in the event of blackouts.

Note:

• connect the valve cable shield to the spade connector and then to the earth;

• for information on the compatibility of valves and refrigerants, see the

Technical Specifi cations table (see chap. 12) and the EVD Evolution driver manual.

On the controller with built-in valve driver it is possible to apply the

Ultracap module (accessory P/N PCOS00UC20) . The module is made with special capacitors called ultracapacitors that close the electronic valve in case of power failures. The module only powers the driver and not the controller.

Important: the c.pCO with built-in driver and PCOS00UC20 module

(or EVD0000UC0 external Ultracap module, or EVBAT00400 battery) must be powered at 24 Vac so that emergency valve closing is ensured in case of power failures. If the controller is powered with DC voltage it will not close the valve in case of power failures.

Note:

• the built-in driver replicates all the hardware and logic functions of the “EVD Evolution” stand-alone driver in case of 1 valve and of the

“EVD Evolution TWIN” driver in case of 2 valves. In other words, it independently controls one or two electronic expansion valves with two-pole stepper motors. The only diff erence with EVD Evolution is that there are no output relays. For details on the valve control logic, set-up and installation, see the EVD Evolution manual (+0300005EN for single driver, +0300006EN for double driver);

• as with EVD Evolution, the built-in driver on the c.pCO controller is available in the CAREL and the “Universal” versions. “Universal” models are used to control both CAREL electronic expansion valves, as well as valves produced by other manufacturers (see the Technical

Specifi cations table, chap. 12), while CAREL models only control CAREL valves.

c.pCO +0300057EN rel. 1.0 - 19.01.2015

ENG

Serial communication and programming

Communication between the c.pCO Medium and its built-in driver is managed internally through the FBus2 serial port. The FBus2 serial port (J26) is however electrically isolated from the driver serial line; this ensures that in case of external faults on the line connected to FBus2, the internal driver can keep on working independently. The driver can only be confi gured using the c.pCO application developed with c.suite; no external display is available for the driver.

The c.suite development environment features a module for managing the EVD Evolution driver. When managing the built-in driver, use the module as if managing an external driver connected to the FBus2 port.

At a c.suite application software level, the valve driver must be connected to the FBus2 port. Consequently, any other devices physically connected to the Fbus2 port (J26) must have the same communication protocol

(CAREL Standard Master or Modbus® Master), the same baud rate, stop bits and parity. The built-in driver address is 198 (EVD Evolution default address), so any other devices connected to J26 must have an address other than 198. Communication frame confi guration is performed by using c.suite environment. External EVD Evolution drivers can be connected to the Fieldbus1 serial port (optional card) with no address restrictions.

(*) dedicated power supply or same power supply as controller: not in common with the power supply for other external loads (e.g. contactors, coils).

Important: using relays that belong to diff erent groups can cause delays in switching.

Important: in applications with SSR outputs:

• the controller should only power resistive loads with load current less than maximum declared;

• use an additional external SSR to power inductive loads;

• for AC power supply to resistive loads or external SSRs, use the same power supply as the controller (connected to terminals G/G0), which must be dedicated and not in common with the power supply to other devices in the electrical panel (contactors, coils, etc.)

5.8 Solid state relay (SSR) digital outputs

c.pCO controllers are also available in versions with solid-state relays (SSR) for controlling devices that require an high number of switching cycles that would not be supported by electromechanical relays. These outputs are dedicated to resistive loads powered at 224 Vac SELV or 28 to 36 Vdc SELV with max. load current up to 1 A or 230 Vac with max. load current up to

70 mA.

Example 1: connection diagram for resistive load.

Note: the SSR load is powered at 24 Vac SELV, 28 to 36 Vdc SELV or

230 Vac; consequently all the other terminals in the group must be powered at the same voltage due to the absence of reinforced insulation within the group.

When the controller is switched on, it runs a test on the secondary display, lighting up the segments one by one.

6.2 Private and shared terminal

All c.pCO controllers can be connected to each other in a local area network (pLAN, see Figure 6.a) in order to share one or more terminals.

Shared 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 controller during normal operation, but can be used just for the initial programming of the main parameters. If one or more terminals are disconnected or malfunctioning, the application program continues to work correctly on each controller. Generally, the application program can monitor the status of the network and intervene as necessary to ensure continuity of the control functions. The fi gure below shows a possible pLAN network connection diagram.

Fig. 6.a

All the terminals and controllers in the network must communicate at the same speed. The speed is adapted automatically.

A maximum of 32 units can be connected, including:

• c.pCO controllers, which run the control program;

• terminals.

Every device belonging to a pLAN network is identifi ed by a unique address, i.e. a number from 1 to 32. The number 32 can be assigned only to a terminal. Programs for diff erent applications (e.g. chillers, air-conditioners, compressor racks, etc.) cannot be automatically integrated into a local network – they must be confi gured according to the system architecture using the CAREL development tool.

Each controller connected to the network can simultaneously manage up to 3 terminals in the pLAN network. The values are displayed on the terminals at the same time and not independently, as if the keypads and the displays were connected in parallel. Because of that, the controller cannot manage diff erent kinds of terminals at the same time.

Each terminal associated with a certain controller is defi ned as:

- private (“Pr”) if it displays only the output of that controller;

- shared (“Sh”) if either automatically or from the keypad it can be switched between various controllers.

Each c.pCO constantly updates the displays on the private terminals, while the shared terminals (if present) are updated only by the c.pCO that is controlling the terminal at that time.

The fi gure below illustrates the logic of the relationships: c.pCO: 1

Fig. 6.b

In this example, the shared terminal is associated with 4 controllers, but at this instant only controller 1 can display data and receive commands from the keypad. Switching between controllers occurs:

1. using a command in the system menu;

2. in sequence (1->2->3->4->1...) by pressing a button defi ned by the application program; however it can also be done automatically when requested by the program. For example, a c.pCO may request control of the shared terminal to display alarms or, vice-versa, relinquish control to the next c.pCO after a set time (cyclical rotation).

Data on the number and type of terminals is determined during initial network confi guration and saved in the permanent memory of each c.pCO controller. Details of the confi guration procedure are described below. See the “Installation” chapter for information on the cables to use for the electrical connections.

6.3 Setting the controller pLAN address

The controller pLAN address is factory-set as 1.

There are two ways to set a controller address:

1. using button A (see the fi gure below) located next to the 7-segment display. This can be accessed using the tip of a screwdriver (ø<3 mm);

2. from the system menu (see Chapter 7).

Displaying the pLAN address

The pLAN address is displayed permanently on the pLAN address display.

6.5 Sharing terminals in a pLAN network

Once connected in a network (pLAN), the c.pCO controllers can share the same pGD terminal. A shared terminal may be needed, for example, to install an update to the operating system and/or application program.

Connect the controllers and terminals to the network (Figure 6.g). Set the pLAN address for each controller using the dedicated button (see paragraph 6.3), and for each terminal using the corresponding procedure).

The fi gure below represents three c.pCO controllers in a pLAN network with three pGD displays, each with their own address.

6.4 Setting the terminal address and connecting the controller to the terminal

After setting the controller network address (see previous paragraph), to establish connections between the controller and the terminal, the terminal address needs to be set. If the controller is connected to an external terminal with address 32 (default setting), communication is established (if the built-in terminal is present, the external terminal replicates the same visualization). To confi gure multiple terminals, private and/or shared, diff erent addresses need to be assigned to the terminals,

If the password entered is correct, the new application program can be uploaded.

3.

At the end of the update procedure, the c.pCO controller restarts automatically with the new application program (or new confi guration).

Important: before updating the c.pCO controller via USB connection, check in the system menu that the Device USB port is enabled (Settings --> USB Settings --> PC connection, see Chapter 7).

Update via USB fl ash drive

All models in the c.pCO family come with a host USB port that can be connected to a USB mass storage device (typically a USB fl ash drive or portable hard drive), from which an application program can be loaded onto the c.pCO programmable controller.

To update the controller, the application fi le with extension .ap1 needs to be created in c.factory and loaded onto the USB fl ash drive:

1.

Open c.factory and select the application program fi le compiled in c.suite (“.otr” fi le extension). The tool will list the confi gurations defi ned in c.design. Select the confi guration to be loaded on the controller and click "next”.

Select the fi les to be loaded onto the controller and click ”Export

Ap1”. In the application package it is possible to include also:

• the Operating System, selecting the specifi c path;

• the web pages for the c.pCO web server functionality (see Chapter 10).

•

Do not use both USB ports on the controller at the same time.

•

Do not use mass storage peripherals that have a current draw more than 500 mA.

Update with fi le transfer via FTP

The c.pCO family controllers fi tted with Ethernet port include an FTP server that provides access to the public partition of the fi le system.

Files and directories in this partition can be read, modifi ed, created and deleted. FTP can also be used to transfer an .ap1 fi le, for example to update the image of the operating system or the application program.

This is done using an FTP client, for example “FileZilla”.

To protect the contents of the public fi le system against unauthorised access, diff erent users can be created, assigning each a diff erent access profi le, dedicated to each service and adapted to the individual directory

(see Chapter 9). To update via FTP:

1. Open an FTP client (e.g. FileZilla). Enter the IP address of the c.pCO controller and the access credentials (default user “anonymous”, no password).

2. Drag & drop the software update fi le from the directory on the computer to the “UPGRADE” directory on the c.pCO controller.

Fig. 6.l

3.

Click “Export” and save the fi le to a fl ash drive, under a directory called

“UPGRADE”.

4.

Plug the fl ash drive into the Host USB port and enter the system menu (see Chapter 7). On the screen, select UPGRADE and then the application program to be loaded and confi rm by pressing enter.

Important: Power supply to the product must only be connected between G and G0. The Vbat terminal is only used for connection to the

Ultracap module as emergency power supply in the event of a power failure.

The dipswitches can be used to set the expansion board serial address

(from 1 to 15), protocol (Modbus or Carel) and baud rate. By serial connection it is possible to modify the electrical confi guration of the line and assign a serial address from 16 to 247 (207 if using the Carel protocol).

Baud rate and communication protocol settings

Board default confi guration is baud rate 19.2 Kbps and Modbus protocol.

The “Baud” and “Prot” dipswitches (see Fig. 6.u) can be used to set the baud rate and the communication protocol used by the expansion board. The unit must be switched off before making the settings on the dipswitches.

Important: if the baud rate and protocol settings are changed on the dipswitches while the unit is on, this must be restarted to activate the new settings.

ENG

Address and serial communication mode settings

To assign to the board a serial address from 1 to 15, simply set the dipswitches as shown in Figure 6.u. The “Ext” dipswitch must be set to

“OFF” (no off set). The unit must be switched off before making the settings on the dipswitches.

Important: if the settings are changed on the dipswitches while the unit is on, this must be restarted to activate the new settings.

To assign to the the board a serial address from 16 to 247 and to confi gure the serial communication settings, an off set needs to be sent to the expansion board via serial communication, which is then added to the

“Address” dipswitch confi guration, and the variable corresponding to the serial transmission parameters needs to be set, as follows:

Example (address setting N=87, serial communication 8, Even, 1):

1.

Set the dipswitches of the “Address” group and the dipswitch “Ext.” a OFF.

2.

Restart the unit. The c.pCOE will go into “Set Mode”. Warning: activating this mode resets both the address off set and the serial communication settings. In this mode, the board serial address will be 207 and the serial confi guration will be 8 bits, no parity and 2 stop bits (8 bits, None, 2). The yellow LED fl ashes.

3.

To set the communication parameters, the “Serial Transmission

Confi guration” variable needs to be set via serial communication

(see Table 6.a and 6.b). In this example, the variable is set to 5

(confi guration 8, Even, 1).

4.

To set the serial address, the “Address Extension” off set variable needs to be set via serial communication (the off set must be greater than

8. PROTECTION: PASSWORD AND DIGITAL SIGNATURE MANAGEMENT

2.

Select the "Protection" tab:

The c.pCO controller implements protection methods aimed at preventing unauthorised personnel from performing certain sensitive operations like updating the software, accessing the system menu, cloning proprietary software, etc.

It is possible to protect the c.pCO controller by setting a password or a digital signature. Signing the controller by digital signature is an irreversible process, while the password can be modifi ed or cancelled.

The password is applied by default in the c.suite development tool, while the digital signature is an additional function enabled with a dedicated license.

8.4 Loading an application program on a controller signed with digital signature

A c.pCO controller signed with a Digital Signature can be used only with an application software signed with the same signature. In order to generate an application signed with Digital SIgnature, it is necessary to follow the procedure described in the previous paragraph and proceed with the installation of the application as described in paragraph 6.6.

If the digital signature for the application program being loaded on the c.pCO does not correspond to the digital signature on the controller, when loading the application program by using c.factory tool, a screen is displayed prompting for the password corresponding to the digital signature currently loaded on the c.pCO.

If the password entered is correct, the program will be uploaded correctly.

Note: if both a protection password and a digital signature have been set on a c.pCO, the latter has priority. c.pCO +0300057EN rel. 1.0 - 19.01.2015

9. ACCESS MANAGEMENT FOR IP SERVICES

c.pCO controllers integrate a Web Server and a FTP Server:

•

Web server: used to access the fi les (HTML pages, images, JavaScript code, etc.) stored under the /HTTP/ directory of the public partition in the fi le system. These pages can show dynamic contents generated by CGI calls (Common Gateway Interface), managed by the controller fi rmware in order to read/write variables of the application and create logs and custom dynamic pages. These pages are accessed in a LAN by using a browser, entering the c.pCO controller IP address or hostname;

•

FTP server: used to access the public partition in the fi le system, to read, edit, create and delete fi les and directories, including web pages.

FTP can also be used to transfer a .ap1 fi le, for example, to update the image of the operating system or the application program. The fi les are accessed using an FTP client, such as “FileZilla”.

For protecting the contents of the public fi le system against unauthorised access, the system administrator can create diff erent users, and assign each user diff erent access profi les, diff erentiated for each service and adapted to the individual directory.

Access confi guration is performed in two steps

1. create users in c.design;

2. create authorisation fi les in the directories of the public fi le system that need to be protected.

Example: the following three users have been created:

User name dave bryan ron

Password davepasswd bryanpasswd ronpasswd

Select the directory where the application program fi les are located and click “Upload” to load these accounts into the c.pCO controller.

Note:

• max number of users: 5;

• max number of characters in the user name: 15;

• max number of characters in the password: 15;

• in addition to the users saved in the database, the FTP server retains the default user, called “anonymous”. This special user allows public access to certain directories and to new c.pCO controllers without any users confi gured. The anonymous user does not require authentication

(any password can be entered) and access will be restricted to the directories that have no authorisation fi les (ftaccess, as illustrated below).

The authorisation fi les contain a list of users who can access the current directory. Only the users listed in the authorisation fi le can access the corresponding directory.

c.pCO does not have any account confi gured by default, consequently the entire public fi le system has read/write access to the default user

(“anonymous”) and web access without authentication. This simplifi es the operations for fi rst installation of the application program and web pages via FTP/HTTP protocol. Subsequently, accounts can be created so as to restrict access to the public fi le system. The accounts who can access the IP services are created in c.design. Open c.design and access the confi guration editor.

Note: an authorisation fi le only prevents access to the fi les in the directory where this is located, and not the fi les in any sub-directories. To disable access to the various sub-directories, the authorisation fi le needs to be copied to each of these.

The authorisation fi le is a simple text fi le, called:

•

“htaccess”, when it authorises users of web server services;

•

“ftaccess”, when it authorises users of FTP server services.

Fig. 9.a

Click “c.pCO Confi g. Editor”: the user confi guration page will be shown.

Enter the user name and password and confi rm by clicking “Add user” for each new user.

Authorisation fi le structure

The authorisation fi le contains a list of user names who are authorised to access the directory in question, one on each line. There is no extension

(e.g. ".txt”).

Example: the authorisation fi le for the three users created previously will have the following layout, and be called “ftaccess” or “htaccess”.

ftaccess/htaccess dave bryan ron

Whenever a user needs to access a fi le (web) or directory (FTP), the following procedure is applied to grant/deny access:

1. verify whether the authorisation fi le (htaccess or ftaccess) exists in the requested directory. If no fi le exists, access is granted;

2. if the fi le exists, this is opened and read sequentially to check whether the user making the request is included in the list; if not, access is denied;

3. if the user is included in the authorisation fi le, the system looks up the user name in the user database. If not found, access is denied;

4. if the user is known, authentication by password is required; if the password is correct, access is granted.

9.2 Computer - c.pCO connection

There are two ways to connect the c.pCO controller to a computer via

Ethernet:

1. computer-c.pCO direct connection;

2. network LAN connection with DHCP server

Computer-c.pCO direct connection

Connect one end of the network cable to the Ethernet port on the computer and the other end to a any of the Ethernet ports on the c.pCO; LEDs blinking indicate correct connection. The Ethernet ports on the c.pCO are auto-crossing (Auto MDI-X), therefore no crossover cable is needed. After connection through Ethernet cable, computer and controller IP addresses must be properly confi gure in order to belong to the same IP subnetwork.

Confi guration example:

Computer:

IP address: 192.168.0.2

Subnet mask: 255.255.255.0

c.pCO controller:

1. press Alarm and Enter together for 3 seconds to access the system menu;

2.

Select Settings -->TCP/IP settings: DHCP = OFF and enter an address in the same subnet set on the PC, for example:

IP: 192.168.0.1

MASK: 255.255.255.0

3.

Select update confi guration --> Yes

Network LAN connection with DHCP server

Before connecting the c.pCO controller to the LAN, access the system menu and verify that DHCP: On (default setting).

Then connect the c.pCO to the LAN. The IP address is automatically assigned to the c.pCO by the DHCP server, and it can be displayed in the system screens (Settings -->TCP/IP settings).

9.3 FTP connection with authentication

Once having connected the computer to the c.pCO via Ethernet, FTP protocol can be used to transfer fi les. The program used in this example is

“FileZilla”, downloadable for free from the Internet.

Proceed as follows:

1. open FileZilla: the following screen will be shown;

2. enter the IP address (or hostname) of the c.pCO controller, the user name --> anonymous and password -->“empty” and select “Quick

Connect”;

3. the user can access all the directories highlighted, as these do not contain the “ftaccess” fi le: UPGRADE, HTTP. Access is also available to the HTTP directory and its sub-directories.

Nota: Please use following settings in Filezilla:

•

Edit->Settings->Connection-> set timeout in seconds = 0

•

Edit -> Settings -> Transfers -> set maximous simultaneous transfers to 1

ENG

Access to the diff erent directories can be restricted, assigning diff erent user lists (see paragraph 9.1).

Important: in the event of errors when copying the authorisation fi les and consequently denial of access, the authorisation fi les can only be deleted by direct connection to the USB device port.

9.4 HTTP connection with authentication

This paragraph shows how to restrict access to the web interface or part of it. In the example, a website is created with several pages in “\

HTTP”, administration pages in “\HTTP\admin” and user pages in “\HTTP\ user”. Only “dave” and “ron” can access the administration pages, while the user pages are only accessible to “bryan”. All three users can see the common pages in “\HTTP”. The authorisation fi les shown in the table need to be created and copied by FTP to the corresponding directories

(see paragraph 9.1):

Accessing an address of the c.pCO Web Server by using a web browser, then a pop-up window will be shown prompting for the user name and password.

Fig. 9.e

If the user name/password are recognised and the user has been authorised to access the directory, for example “dave”, the web server grants access to the pages, and these can be displayed by the browser.

10. WEB SERVER AND TERA CLOUD PLATFORM

c.pCO controllers family features an integrated web server that can be completely customised by the user. The c.pCO web server can support HTML and JavaScript standards. Custom web pages can be copied in the public fi le system, in the /HTTP/directory. c.pCO implements some CGI (Common

Gateway Interface) scripts that allow to dynamically read and write application variables in order to create dynamic content. A freely customisable package called “Web kit” is available to simplify the creation of custom webpages for the c.pCO. The Web kit comprises sample HTML pages and JavaScript libraries for managing dynamic CGI, fully exploiting the potential of the c.pCO web server. In particular, the examples provided can be used to:

1. display the contents of the pGD1 on the browser pages (pGDWeb, see paragrap 10.3)

2. display the list of public variables in the application program, allowing the values to be read and write;

3. display the network status, with the addresses of the connected devices;

4. plot data on graphs, both in real time as well as extracted from logged data.

10.2 Contents of the package

Directory Sub-directory Contents imgs Images used by all the pages lib File libraries: CSS (Cascaded Style Sheet) and

JavaScript for dynamic variable handling, graphs from logs and graphs in real time. Default CSS pgd calendar jscolor imgs fi le (optimised for browser with 1024 pixel resolution)

Graphic elements (calendar) used by the log pages

Graphic elements (color picker) used by the log pages pGD web interface: do not delete or remove fi les from here. Index.html can be customised, so as to change the pGD eeb screen.

Image fi les used by the pGD web interface: do favicon.ico

not delete or remove fi les from here

Browser “favourite” icons, can be completely customised

Tab. 10.a

10.1 Web kit download and installation

The freely customisable web package called “Web kit” can be downloaded in ksa.carel.com. The package must be saved in the c.pCO public fi le system:

1. unzip the .zip fi le;

2. copy the contents to the /HTTP/ directory in the c.pCO fi le system by using the USB device port or FTP protocol through Ethernet (see picture below).

3.

Disconnect Usb cable from USB device port.

10.3 Web pGD

The virtual terminal shows the information displayed on the pGD terminal connected to the c.pCO in real time.

4.

After copy of the Web kit package into folder /HTTP/, it is possible to the c.pCO and the computer in the same local network and write in the browser address bar the c.pCO IP address (see paragraph 9.2).

The web pages are independent from application software loaded into the controller, and they are developed to be customized according to the specifi c application.

10.5 Variable trend (logger)

The names of the logs are loaded dynamically by the c.pCO based on the Log editor settings in c.design. This means the drop-down menu for choosing the log to be displayed is populated automatically, without having to modify the web page:

• choose the log to be displayed from the drop-down menu at the top;

• set the display interval, as start and end date/time or using the quick links on the right, used to load the last ‘N’ days/weeks logged;

• click “Load log data” to load the log and display the corresponding graph.

The graph can then be adapted using the mouse (or touch, when using a touch screen) to zoom, change the colour of the lines, display the numeric values of the variables at a certain point on the graph, or enable the secondary axis.

A screenshot in image format can be saved at any time, or the data exported in CSV format.

Ethernet interface is natively integrated into tERa cloud platform and can access to linked services. Every c.pCO is uniquely identifi ed by the tERA cloud using its MAC address. It is possible to create a customized private portal according to the customers specifi cations. For further information on tERA services available, contact your local Carel sales network.

Fig. 10.g

c.pCO registration:

Activation and registration procedure and settings of the tERA services are described in the "tERA Quick start Guide" (document +030222141), that can be download from www.carel.com.

Following data are requested in order to register a c.pCO in tERA server:

•

MAC address of the c.pCO

• c.pCO serial number (S/N)

• tERA password

Above data are reported in the c.pCO System menu at the following path:

INFORMATION --> pCO INFORMATION (see fi gure below).

Fig. 10.e

Choosing the “Live” tab activates a real time graph of the variables, chosen from the list of public variables.

• Click “Show/Hide variables” to show the variable list (automatically populated by the c.pCO).

• Choose the variables to be displayed from the list

• Choose the sampling period (expressed in seconds) and the display interval (expressed in minutes)

• Click “Play” to start acquiring the data

In this case too, the graph can be adapted, even during the acquisition process.

c.pCO Update from tERA

From tERA portal, it is possible to update the application program and the Operating System of the c.pCO by remote. The controller should be already registered in the tERA portal.

Procedure is described in "tERA Quick start Guide" (document

+030222141), that can be download from www.carel.com.

• the two 230 Vac or 24 Vac/Vdc inputs on terminals J8 (ID13, ID14) or J19 (ID15, ID16) have the same common pole and must therefore be powered at the same voltage

(230 Vac or 24 Vac/Vdc). There is functional insulation between the two inputs; there is reinforced insulation between the inputs and the rest of the controller;

•

ID1...ID8, ID9 to ID12, ID17, ID18 have functional insulation from the rest of the controller;

• for DC voltage inputs (24 Vdc) either the + or the - can be connected to common terminal;

• the rating of the external contact connected to the digital inputs must be at least 5 mA.

• for lengths greater than 10 m use a shielded cable with earthed shield;

The relay outputs have diff erent features depending on the controller model. The outputs can be divided into groups. Relays belon-

Insulation distance ging to the same group (individual cell in the table) have operational insulation and must therefore be powered at the same voltage.

Between groups (between cells in the table) there is reinforced insulation, so the relays can be powered at diff erent voltages. There is

Composition of groups also reinforced insulation between each terminal of the digital outputs and the rest of the controller.

Warning:

• if the load requires a higher current, use an external SSR. To power external loads, use the same power supply as the pCO (connected to terminals G-G0); this must always be dedicated and not in common with the power supply to other devices (e.g. contactors, coils, etc.);

• to simplify wiring, the groups of digital outputs have two common pole terminals;

• make sure that the current running through the common terminals does not exceed the rated current of each terminal, i.e. 8A.

Note: in industrial/residential applications with distances greater than 10 m, use shielded cable with earthed shield.

In residential applications (EN 55014), regardless of cable length, in versions without valve driver, the connection cable between controller and terminal and the serial cable must be shielded and earthed on both sides.

Emergency power supply Optional Ultracapacitor module (PCOS0WUC20 or EVD0000UC0). If the controller works constantly at temperatures near the upper limit of 60°C it is recommended to use the external module P/N EVD0000UC0, if possible placed in the coolest point of the panel.

Modules PCOS0WUC20 and EVD0000UC0 can be connected to the same controller at the same time, thereby doubling the energy available for closing the valves. Important: the module only powers the valve driver and not the controller.
