“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

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”;

TECHNICAL DATA

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

• The edges of the cut-out must be flat;
• Tighten each fixing screw until the corner of the plastic faceplate comes into contact with the panel; ·

The cut-out 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

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 umpired 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 M 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.
