1 GENERAL

1.1 Scope of the manual

The scope of this manual is to provide all information required to use the pCO3 _control. This version of the manual has been updated to software version 2.5.

The new software has involved a large number of amendments so it is advisable to use relative manuals for previous versions of the software.

1.2 Control functions

The pCO3 _{microprocessor electronic control with the FLBB0MP20A program is for managing chiller units and heat} pumps.

The program can be configured to manage units with water and air condensation, tube and plate heat exchangers, separate and parallel cooling circuits.

Management of chiller units means controlling safe operation of the components during their intended operation phases.

Furthermore, if a single card does not offer a sufficient number of inputs and outputs, several cards can be interconnected to form a local pLAN network.

(5)

2 USER INTERFACE

The user interface has six keys and a display screen with 20 columns and 4 lines. The interface can be used to start and stop the unit and check running status.

The information displayed on the screen show current running status and the six keys can be used to carry out all operational tasks.

PGD0 user interface The functions of the six buttons are as follows:

Button: “up arrow” to scroll through the forms in the branches and to increase values in the various fields.

Button: “down arrow” to scroll through the forms in the branches and to decrease values in the various fields.

Button: “Button enter” to confirm a selection, access the various branches and change the parameters.

Button: “Button alarm” to stop a buzzer, to display and, if required, cancel active alarms.

Button: “Button prog” to access the loop of forms in the various branches.

3.1 General

The branches enable access and setting of the parameters at various access levels.

Each branch is at a different access level which may be password protected or require a particular combination of buttons.

If no buttons are pressed for 5 minutes, regardless of which branch you are in, the control automatically returns to the main menu.

The values and settings in the branches of the manual are for illustrative purposes only, and not those on the units. The real values on the installed controls differ according to the unit’s installation and features.

3.2 The list of branches

These are the branches: Service, Maintenance, GSM, Clock, Menu, Set, I/O and Log.

To access the branches, press the “prg” button and the control displays a branch with a continuous loop where all the available menus are mentioned on three lines.

The branch comprises two lateral lines of normal width and a double central line corresponding to the selected branch, as shown in the example.

M_MAIN_SCROLL Change

Italian: “Menù”; “Set”; “I/O”; “Orologio”; “GSM”; “Manuten.“; “Service”; "On/Off"; and "Cambio". English: “Menù”; “Set”; “I/O”; “Clock”; “GSM”; “Mainten.“; “Service”; "On/Off"; and "Change".

4 UNIT OPERATION

4.1.1 Unit in stand-by

The unit is in stand-by when it is correctly powered electrically and hydraulically, but not enabled to operate.

In this status, the control will display the values read by the analog inputs and the status of the digital inputs and outputs.

To enable the unit from stand-by mode:

- close the digital input for remote consent between terminals 1 and 2;

- give the command to start up on the keyboard or via serial port from supervisor and/or Boss.

4.1.2 Abilitazione e arresto dell’unità

The unit is enabled to operate when the outputs can be activated automatically in accordance with the system’s requirements.

This occurs when there is simultaneous presence of all the consents for operation, as described in the previous paragraph.

The key pad is activated through the “On/off” mask.

The unit detects the system’s requirements by reading the water probe if it operates as stand-alone, or by means of the signal sent from the boss if it operates on a network with other devices.

The control’s outputs that command the various parts of the chiller unit are activated in accordance with the relative operation modes.

4.1.3 Chiller unit and heat pump operation

All chiller units refrigerate water.

Heat pump units refrigerate water for summer air conditioning, but can also heat it to provide heating in winter. Water temperatures for cooling and heating are preset by the manufacturer to standard norms, but can be modified, within limits, as required.

Change from summer to winter mode can either be automatic by external input or managed through the keyboard. The changeover mode is set by the manufacturer and can only be modified by a technician.

Water temperatures and changeover mode settings, when this can be keyed in, are accessed through the “Set” branch mask.

4.1.4 Double set operation

Some units on special plants can supply cold water at two different temperatures, usually, but not necessarily, one positive and one negative.

The two operational values in “set”, are preset by the manufacturer, according to the project requirements, but can be modified within the established limits.

Operational settings may be changed automatically by external input or managed through the keyboard. Operational settings change mode is set by the manufacturer and can only be modified by a technician.

Operational settings and change mode settings, when this can be keyed in, are accessed through the “Set” branch mask.
