  3. Introduction

  4. Introduction: positioning in the electrical panel

  5. Introduction The pCO1 series has been designed for the purpose of providing the significant innovations introduced by the pCO system to all those applications that require greater competitiveness in terms of price. All the pCO1 series controllers feature a 16-bit microprocessor, and 2 MB flash memory (multi-language, multi-protocol).

  6. Introduction The pCO1 controllers are available in two different sizes, according to the I/O and power requirements: pCO1 Small, pCO1 Medium. Some models feature an SSR to control the devices that require frequent starts and stops.

  7. Technical Features • 14 MHz, 16 bit microprocessor, 16bit internal register and operations, • 512 byte internal RAM; • Up to 2 Mbyte FLASH MEMORY for the program; • 1 RS485 serial connector for pLAN; • • Ready for connection to RS485supervisory network; • • DIN plastic case for DIN rail installation; • • 24Vac/Vdc power supply; • • Telephone connector for pCO terminals; • • Power on LED.

  8. Technical Features The pCO1 controller is fitted with a 16bit microprocessor to run the control program, and of a set of terminals required for the 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 pCO1 controller also allows connection to a local pLAN network made of a series of pCO1 boards and terminals. Up to 10 units can be connected in the same pLAN net

  9. Application Software The power of the application software means that the user terminal allows: • the initial programming of the unit, with password-protected access to guarantee security; • the possibility to modify, at any time, the fundamental operating parameters, optionally protected by password; • the display and audible signalling (by buzzer) of any alarms; • the display of the active functions, using the LEDs; • the display of all the values measured;

  10. One possible set of hardware • User terminal with keypad, display and • signal LEDs; • pCO1 (SMALL version); • pCO1 (MEDIUM version); • connection cable between the terminal and pCO1; • connection cable between the terminal and serial printer (supplied by the customer); • AWG20/22 cable for pLAN connection between a series of pCO1 boards; • Connection terminal kit; • Connection to supervisor systems.

  11. pCO1 Small and Medium PCO1 SMALL • 8 optically-isolated digital inputs, 24Vac 50/60Hz or 24Vdc; • 8 digital relay outputs (1 of which with changeover contact and 2 optional SSR); • 4 analogue inputs, configurable as NTC, 0/1V, 0/5V, 0/20mA, 4/20mA. • 2 analogue inputs, configurable as NTC and ON-OFF • 2 x 0/10Vdc analogue outputs. • 2 PWM outputs for phase-cutting speed controllers.

  12. pCO1 Small and Medium PCO1 MEDIUM • 12 optically-isolated digital inputs, 24Vac 50/60 Hz or 24Vdc; • 2 optically-isolated digital inputs, 24Vac/Vdc or 230Vac (50/60Hz); • 13 digital relay outputs (3 of which with changeover contact and 4 optional SSR); • 4 analogue inputs, configurable as NTC, 0/1V, 0/5V, 0/20mA, 4/20mA. • 2 analogue inputs, configurable as NTC and ON-OFF • 2 NTC analogue inputs • 2 x 0/10Vdc analogue outputs. • 2 PWM outputs for phase-cutting speed controllers.

  13. Basic layout of the pCO1 medium

  14. Basic layout of the pCO1 medium • 01. Power supply connector [G (+), G0 (-)] • 02. 250Vac, 2A fuse, slow-blow (T2 A) • 03. Universal analogue inputs, NTC, 0/1V, 0/5 V, 0/20mA, • 4/20mA • 04. Passive analogue inputs, NTC and ON/OFF • 05. Passive analogue inputs, NTC • 06. Yellow power LED and 3 signal LEDs • 07. 0/10V analogue outputs and PWM phase-cutting • outputs • 08. Digital inputs, 24Vac/Vdc • 09. Digital inputs, 230Vac or 24Vac/Vdc • 10. Connector with Vref for power to 5V ratiometric • probes, and Vterm for power to ARIA terminal • 11. connector for all the standard pCO* series • terminals and for downloading the application • software • 12. pLAN local network connector • 13. connector for the programming key • 14. digital relay outputs • 15. door for selecting the type of analogue inputs • 16. door for inserting the serial card: • RS485 for supervisor • RS232 for modem interface • Gateway (protocol converter) • 17. door for inserting the clock card

  15. Basic layout of the pCO1 medium Regarding the meaning of each connector and of the correspondance between inputs – outputs, in the manual you’ll find a precise table with all the descriptions. The following table gives examples of the distribution of the inputs and outputs in relation to the 2 versions

  16. Connecting the analogue inputs The analogue inputs can be configured for the more common sensors on the market: NTC, 0/1V, 0/10V, 0/20mA, 4/20mA. The different types of sensors can be selected using the corresponding dipswitches, as in the following figure.

  17. Connecting the analogue inputs This is a picture taken directly from the electrical diagram inserted between the documentation at the moment of the unit delivery. In the last pages, before the components list, there is the specific dipswitches configuration.

  18. Connecting the analogue inputs • In this way you can: • Connect active temperature and humidity probes • Connect universal NTC temperature probes • Connect 4/20mA pressure probes • Connect 0/5V ratiometric pressure probes • Connect the analogue inputs selected as ON/OFF • Connect the digital inputs • Connect 24Vac digital inputs The pCO1 features up to 14 digital inputs for connecting safety devices, alarms, device status, remote switches. These inputs can work at 24Vac, 24Vdc and some at 230Vac.

  19. Connecting the analogue inputs 8. Connect the 230 Vac digital inputs The following figure represents one of the more common Connection diagrams for the 230Vac digital inputs. Within each group, the digital inputs are not independent: for example, with reference to Figure, the inputs ID13 and ID14, 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 230Vac. 9. Connect the 0/10Vdc (optoisolated) analogue outputs The zero volt must be the reference

  20. Connecting the analogue inputs 10. Connect the PWM analogue outputs (for phase cutting speed controllers) 11. Connect the digital outputs (up to 13 with electromechanical relays)

  21. Evd 400 The EVD 400 driver for EEV with two pole stepper motors , is a controller that manages the electronic expansion valve.This function is achieved by optimising the opening of the valve using a PID algorithm and special control routines. The module is fitted with an Rs485/Tlan interface for connection to a Pco1via Tlan protocol

  22. Supervisory systems • Optional card used to interface with • a HAYES standard modem. • The maximun baudrate is 19200 baud • Optional card for interfacing with an RS485 network. • The maximun baudrate is 19200 baud

  23. Supervisory systems The cards are used to interface the pCO1 to a LonWorks network. They differ by the type of interface on the LonWorks network side: Interface to FFt-10A 78kbs (TPFT-10) The baudrate must be set to 4800 Interface to RS485 39 kbs (TP485-39). The baudrate must be set to 4800

  26. Optional Features Option that allows the management of the time and date, it and includes buffer RAM for data relating to the software application. Optional module for expanded the pCO1 memory (event log or Black-box features), and for the management of the time and date

  27. Optional Features The cardscan be used to transfer (upload ad dowload) the aplication software. The key has 2MB flash memory. Carel supply the key with BOOT and BIOS that manage 1MB, in this way the same key can be used with pCO1 contollers that have either 1MB or 2MB flash memory chips.

  28. Optional Features This interface is used to control the main parameters of the Carel OEM humidifiers (water level and conductivity in the cylinder, TAM current power sensor) directly from the pCO sistema controllers. The values read by the special sensors are converted into signals that are compatible with the inputs on the control board. The board is managed by the software application running in the pCO controller.

  29. Optional Features The expansion boards belong to the pCO sistema family and have been designed to increase the I/Os on the pCO3, pCOXS, pCO1, pCO2 controllers. A maximum of 5 expansion boards for each pCO3, pCOXS, pCO1, pCO2 controller can be connected.
