Introduction: positioning in the electrical panel

The pCO1 seriespCO1 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).

Introduction

6

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.

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

The pCO1 controller is fitted with a 16bit microprocessor to runthe 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 madeof a series of pCO1 boards and terminals. Up to 10 units can be connected in the same pLAN net

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;

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 andoutputs in relation to the 2 versions

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:

1. Connect active temperature and humidity probes

2. Connect universal NTC temperature probes

3. Connect 4/20mA pressure probes

4. Connect 0/5V ratiometric pressure probes

5. Connect the analogue inputs selected as ON/OFF

6. Connect the digital inputs

7. 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

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/orthe powering of lower-voltage circuits at 230Vac.

9. Connect the 0/10Vdc (optoisolated) analogue outputs The zero volt must be the reference

11. Connect the digital outputs (up to 13 with electromechanical relays)

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

27

Optional Features

The cards can 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
