“LOGIN” PAGE (ACCESS)

The hmi, once powered and connected via the serial line to one or more coolers, displays the screen shown

in Pic. 1, with the following information:

1) Button for logging in;

Default:

• Enter “admin” as the “user name”;

• Enter “password” as “password”.

After the first access, the installer can choose the access credentials or create new ones with different access

properties.

2) Available languages;

3) System date and time;

4) Installed software version.

_______________________________________________________________________________________

“MAIN” PAGE

After logging in, you access the "Main" page which shows an overview of the system, each cooler is

represented here by an icon.

1) Cooler icon;

The number in the top left-hand corner identifies the cooler, the background colour of the box indicates the

area to which it belongs, transparency indicates a machine configured as single.

The colour of the stylised fan represents the four states of the cooler:

• Offline - (black icon);

• Standby - (yellow icon);

• Running - (green icon);

• Fault - (red icon).

The box at the top right shows the function of the cooler:

• Cooling;

• Ventilation;

• Exhaust;

• Cleaning.

“SETTINGS” PAGE

The main purpose of this page is to define how many and which of the potential 31 coolers managed by the

system are actually present and with which address:

1) Icons of this type allow you to define which coolers are present (blue icons) and which are not (transparent

icons). The address of a cooler is defined during installation by means of the multiple selector on the

board. It is advisable to note down the addresses used during installation so that they can be set correctly

on this page.

_______________________________________________________________________________________

“TIMER” PAGE (TIME SCHEDULE)

The timer page (Time schedule) allows you to program the operation of the system, you can create time slots

within which you can set:

• On which days the function is active;

• The time at which the action applies;

• The action you want to programme;

• The rotation speed of the fan;

• The set point in temperature.

Consistent definitions of a time for an "On" and one for an "Off" define an operating range. An exception

is "Clean" where only the start time needs to be defined, as the duration of the function is set in the

"Maintenance" page, via the variable "Clean duration" expressed in minutes.

1) Menus for creating operating time slots must be set:

• Days of operation, on a weekly basis;

• A time expressed in hours before and minutes after;

• Fan rotation speed;

• Temperature set point;

• The type of action.

Once the parameters have been defined, use the icon with the green tick to confirm your choices, and the icon

with the red cross to cancel your entries;

2) What was defined in the menu in step 1, once saved, is summarised in a line that shows:

• The days of the week on which the action applies;

• The time at which the action applies;

• The type of action;

_______________________________________________________________________________________

• Rotational speed;

• Temperature Set point.

Each time slot, once created, can be modified at a later date by clicking on the green icon to the left of the time

slot; to delete a time slot, click on the red icon to the right of the time slot.

NOTE: The system knows the day of the week corresponding to the date. The panel is equipped with RTC

and buffer cap to maintain the time in case of power failure.

_______________________________________________________________________________________

“MAINTENANCE” PAGE

The "Maintenance" page allows you to:

1) Set when to display the maintenance banner;

2) Clean Scheduler, i.e. the number of hours of continuous operation, after which the "Clean" function is activated.

Minimum value 1 hour, maximum value 72 hours, in steps of 1 hour;

3) Clean duration, determines the duration of the clean function;

4) This option enables or disables cleaning after a cooling cycle;

5) This item allows you to set the maximum permitted humidity level, above which cleaning is converted to

ventilation;

6) Icons for language selection.

_______________________________________________________________________________________

“USERS SETTINGS” PAGE

The "Users Settings" page allows you to create, edit or delete HMI access credentials by choosing "User

name", "Password" and access level.

1) Icon for creating a new access credential by filling in a form;

2) Icon for deleting a new access credential, using a special form that displays the credentials entered in the

device;

_______________________________________________________________________________________

3) Icon for editing a new access credential, using a form similar to the one in point 1;

4) Icon to import login credentials from another device via USB;

5) Icon for exporting login credentials from another device, via USB;

6) Icon to return to the "Main" page.

_______________________________________________________________________________________

“LOG SETTINGS” PAGE

The "Log Settings" page manages the creation of a .csv file on a monthly basis, which records the measured

temperatures of the active coolers at 30-second intervals, and at the end of the hour sends the data to the

network based on the type of storage selected.

Archiving can be done by:

• “FTP”;

• “Shared Folder”.

The following fields must be completed on the basis of the choice made:

• “FTP Server”;

• “Port”;

• “User”;

• “Password”.

Or:

• “PC”;

• “User”;

• “Password”;

• “Path”.

it is also possible to choose whether the .csv file will use the comma (“,”) or a semicolon (“;”) as separators.

The correct installation procedure must be followed to comply with front panel protection ratings:

• The edges of the cutout must be flat;

• Tighten each fixing screw until the corner of the plastic faceplate comes into contact with the panel;

• The cutout for the panel must be the size indicated in this manual.

The equipment is not intended for continuous exposure to direct sunlight. This may accelerate the ageing

process of the front panel film.

The equipment is not intended for installation in contact with corrosive chemicals. Check the resistance of the

front panel film to a specific compound before installation.

Do not use tools of any kind (screwdrivers, etc.) to operate the panel touchscreen.

IP66 is only guaranteed if:

• Maximum deviation from the surface plane to be cut out: <= 0.5 mm;

• Thickness of the housing in which the equipment is mounted: 1.5 mm to 6 mm;

• Maximum surface roughness where the gasket is applied: <=120 um.

_______________________________________________________________________________________

INSTALLATION PROCEDURE

Pic.6

Position the fixing brackets contained in the fixing kit as shown in Pic. 6.

Tightening torque: 75 Ncm. Tighten each fixing screw until the corner of the frame is in contact with the panel.

CONNECTIONS

1) Serial Port;

2) Ethernet Port;

3) USB Port;

4) Power Supply.

To operate with a 2-wire RS485 modbus, pins 4-3 and 8-7 must be jumpered externally.

ETHERNET PORT

POWER SUPPLY, EARTHING AND SHIELDING

The terminal block of the power supply unit is shown in the following figure.

NOTE: Ensure that the power supply has sufficient power capacity to operate the equipment.

The unit must always be earthed with a minimum cable size of 1.5 sq. mm. Earthing helps to limit the effects

of noise due to electromagnetic interference on the control system.

Also earth terminal 3 on the power supply terminal block. The power supply circuit may be floating or earthed.

In the latter case, earth the common power source as shown in the figure with a dotted line.

When using the floating power scheme, note that the operator panels internally connect the power supply

common to earth with a 1 MΩ resistor in parallel with a 4.7 nF capacitor. The power supply must have double

or reinforced insulation. All electronic devices in the control system must be properly earthed. Earthing must

be carried out in accordance with the applicable regulations.
