Introduction 3

Introduction: positioning in the electrical panel 4

Introduction The p. CO 1 series has been designed for the purpose of providing the significant innovations introduced by the p. CO system to all those applications that require greater competitiveness in terms of price. All the p. CO 1 series controllers feature a 16 -bit microprocessor, and 2 MB flash memory (multi-language, multi-protocol). 5

Introduction The p. CO 1 controllers are available in two different sizes, according to the I/O and power requirements: p. CO 1 Small, p. CO 1 Medium. Some models feature an SSR to control the devices that require frequent starts and stops. 6

Technical Features • 14 MHz, 16 bit microprocessor, 16 bit internal register and operations, 512 byte internal RAM; • Up to 2 Mbyte FLASH MEMORY for the program; • 1 RS 485 serial connector for p. LAN; • Ready for connection to RS 485 supervisory network; • DIN plastic case for DIN rail installation; • 24 Vac/Vdc power supply; • Telephone connector for p. CO terminals; • Power on LED. 7

Technical Features The p. CO 1 controller is fitted with a 16 bit 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 p. CO 1 controller also allows connection to a local p. LAN network made of a series of p. CO 1 boards and terminals. Up to 10 units can be connected in the same p. LAN net 8

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; 9

Basic layout of the p. CO 1 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 15

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

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. 17

Connecting the analogue inputs In this way you can: 1. Connect active temperature and humidity probes 2. Connect universal NTC temperature probes 3. Connect 4/20 m. A pressure probes 4. Connect 0/5 V ratiometric pressure probes 5. Connect the analogue inputs selected as ON/OFF 6. Connect the digital inputs 7. Connect 24 Vac digital inputs The p. CO 1 features up to 14 digital inputs for connecting safety devices, alarms, device status, remote switches. These inputs can work at 24 Vac, 24 Vdc and some at 230 Vac. 18

Connecting the analogue inputs 8. Connect the 230 Vac digital inputs The following figure represents one of the more common Connection diagrams for the 230 Vac digital inputs. Within each group, the digital inputs are not independent: for example, with reference to Figure, the inputs ID 13 and ID 14, 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. 9. Connect the 0/10 Vdc (optoisolated) analogue outputs The zero volt must be the reference 19

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) 20

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 Rs 485/Tlan interface for connection to a Pco 1 via Tlan protocol 21

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 p. CO 1 memory (event log or Black-box features), and for the management of the time and date 26

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

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 p.

The board is managed by the software application running in the p. CO controller. 28
