User interface (PGD1)

The unit control panel allow the quick setting and display of the unit’s operating parameters. The board memorises all the default settings and any modifi cations. By installing the remote control panel PGD1 it is possible to remotely replicate all the functions and the settings available on the unit. After a power failure the unit is capable of an automatic restart, retaining the original settings.

INTERFACE CONTROL KEYS:

Control keys

The user interface consists of a graphic display with six navigation keys; the display is arranged through a menu hierarchy, activated by pressing the navigation keys. The default display of these menus is the main screen. The navigation between the various parameters is by using the arrow keys located to the right of the display. These keys are also used for the modifi cation of the selected parameter.

Start-up procedure

After having powered up the unit the control board will carry out preliminary operations before being ready for use. This initial procedure takes around 60 seconds to complete. During the initial loading procedure two screens are displayed: a start-up screen and a screen to select the system language.

These screens are detailed in the table below.

WARNING: The system language can be set on the screen displayed at the startup or can be modifi ed at any time through the appropriate screen contained in the

Installer menu.

Menu structure and navigation

Both the functions to control the unit and the operating information are displayed on the unit mounted control panel.

All the functions and information are arranged in screens which in turn are grouped into menus.

During the normal operation of the unit the main screen is displayed, from which it is possible to access the selection of the other operating menus.

The menus are displayed through the rotation of the icons that they represent. Once the desired icon is selected the chosen menu is entered, permitting the display or modifi cation of the parameters that it is made up from. The procedure for navigating the menus, or changing parameters, is explained in detail in the chapter “User operating procedures”.

The adjacent drawing shows the relation between the various menus and the navigation keys used.

The operating menus are arranged as in the following drawing:

• FIRST DEFROST: shows the first defrost phase after a power loss

Additional defrost information: provides additional status information on the defrost:

• HIGH EXTERNAL AIR TEMPERATURE: the external air temperature is above the level for enabling defrost

• CIRCUIT OFF: all the compressors of the circuit are off; defrost is disabled

• LP ABOVE LIMIT: the low pressure is above the level to enable defrost

• MINIMUM TIME BETWEEN DEFROST: defrost is disabled during the period of minimum time between defrosts

• START CP: compressor just started; await the bypass time before calculating the pressure decrease

• NEW LP REFERENCE: a new low pressure value has been taken as reference for the calculation of decreasing pressure;

• START FOR LP LIMIT: start of defrost to overcome the low pressure limit

• START FOR DELTA P: start of defrost to overcome the decreasing value of low pressure

• TEMP. LIQUID OK: the liquid temperature has overcome the limit to define the end of defrost

• MINIMUM DEFROST TIME: defrost continuous until the minimum time is exceeded even if the exit conditions are met

• AWAITING OTHER CIRCUIT: occurs if the fans are common to both circuits and the first circuit to finish defrost awaits the second circuit to finish

• BYPASS FIRST START: the first defrost after a power loss can only occur after the compressor has run for the determined time

• LIQUID TEMP. LOW: liquid temperature below the level that determines the end of defrost

• START FOR DGT: defrost is activated due to the level of the discharge gas temperature exceeding the limit

• FORCED: in the case the fans are common to both circuits this circuit has been forced into defrost due to defrost of the other circuit, even if not required

Defrost time: the value can indicate the maximum time before completing defrost (in the event the normal levels for completion have not been met), or the minimum defrost cycle time (in the event the “TEMP. LIQUID OK” message is displayed), to exit defrost

Low average pressure: shows the average low pressure in the last minute

Delta pressure: shows the accumulated delta pressure to determine activation of defrost

Liquid temperature: shows the liquid temperature to determine exit of the defrost cycle

Alarm summary table

The unit provides a display of the possible faults, announced by the fl ashing of the alarm key with the bell symbol located on the left of the display. Pressing the bell key displays the alarm. The reset of the alarm can be automatic, manual or semi-automatic on the basis of the type and severity of the alarm.

To reset the alarm message it is necessary to press the bell key again, but this does not reset the cause of the alarm, but only acknowledges it.

The following table lists the faults that can be generated by the unit and a brief explanation of the possible cause.

Alarm reset types:

Manual reset:

Unit is reset manually by removing and re-applying power.

Automatic reset:

The unit is reset automatically

Semi-automatic reset:

The unit is reset semi-automatically if the alarm is repeated a maximum of three times consecutively, and after a further alarm requires manual reset.

Alarm history

Each time an alarm is generated it is saved in the “alarm history” memory.

This memory contains the last 100 alarms recorded. For each alarm saved the inlet and outlet water temperatures are also recorded, so that the service personnel can have a clear picture of the unit at the time the alarm occurred.

To access the alarm history:

(a) Press the key ( ) and enter the alarm display.

(b) If any are present, go through the active alarms with the key ( ) and reach the icon that gives access to the alarm history.

(3) Press the key ( ) to enter the alarm history.

(4) To exit the alarm history press the key (

Prg

) or the key (

Esc

).

Alarm history - Refrigerant circuit pressure info: pressing the enter key during the display of the alarm history the water temperature data is replaced by the high (HP) and low (LP) pressure values measured on the refrigerant circuit at the time the alarm occurred

Note: further pressing of the enter key alternates between the water temperatures and the circuit refrigerant pressures

!

THE ALARM HISTORY CANNOT BE CANCELLED and having a limit of 100 alarm histories, any additional new alarms after the index value 99 will incrementally start with the index value 00 and overwrite the old data.
