Controller interface panel

The hot air generator is managed by a microprocessor controller that is installed in the burner compartment and is
used to control, set up and troubleshoot all the operating parameters of the equipment.
An interface panel is provided in the burner compartment that is used to carry out all operations required to operate
the equipment, to set up the parameters, and to detect alarms.
The buttons "arrow up", "arrow down", "ESC" and "ENTER" and the display are used to surf the various menus.
Parameter editing is password-protected.
For additional information on how to use the user interface and its multiple functions, refer to the documentation
supplied with the hot air generator.

First commissioning

The generator must be commissioned by authorised staff.
The generator is supplied already set up and tested for the gas type specified in the ID plate.
If gas is smelt:
- do not engage any electric switch, phone or other object or device likely to generate sparks;
- close the gas valves;
- ask for the help of qualified staff.
The following checks must be performed before switching the generator on:
- check that the gas supplied from the network matches the gas type for which the generator is set up;
- use the pressure inlet "IN" on the gas valve to check that the input pressure into the valve matches the pressure
value required for the gas type in use;
- check that the electrical connections match the connections specified in the wiring diagram of the unit;
- check for obstructions in the combustion air inlet grid (e.g. leaves, etc.);
- check that an effective connection to earth has been implemented and made as required by the safety rules in
place.
When the generator is switched on for the first time, the pilot burner frequently happens to fail to get
ignited due to air in the gas pipe, which causes the equipment to get stuck.
The cause of ignition failure must be cleared and the operation repeated until the burner ignites.
It is prohibited to loosen the gas fittings, the pressure taps, the duct of the pilot burner or any other
gas connection point inside the burner compartment for the purpose of purging either air or inert gas
that may still be present in the main intake pipe.
Air or inert gas must be purged from the gas intake lines in accordance with the existing legislation.
We reserve the right to make changes without any prior notice.
