L'apparecchiatura controllo fiamma fa partire il ventilatore del bruciatore per effettuare il prelavaggio della camera di combustione,
controllando la pressione dell'aria di ventilazione tramite il pressostato aria. Al termine della preventilazione entra in funzione il tra-
sformatore di accensione generando una scintilla tra gli elettrodi e contemporaneamente si aprono le valvole del gas (valvole gas di
sicurezza VS e 1° stadio valvola lavoro VL). La sicurezza totale in caso di mancata accensione o di spegnimento accidentale viene
affidata ad una sonda di rivelazione a ionizzazione che interviene mandando in blocco l'apparecchiatura entro il tempo di sicurezza.
Nel caso di mancanza di gas o di un calo notevole di pressione il pressostato gas di minima provvede ad interrompere il funziona-
mento del bruciatore.
The SATRONIC DLG 976 control is a micro-processor control which provides information about the current opera-
tion of the burner and the cause of any faults. The information is available by reading the "flash code" at the red LED
within the lockout reset button as detailed below. By the use of additional monitoring equipment a short history of
recorded faults is also available. There are two types of additional monitoring devices available from Satronic Ltd. The
"satropen" is a small pocket reader designed to give a visual read out of status, flame current and supply voltage.
Computer software is available to allow access to the current information and stored data.
On burner failure the red LED is permanently illuminated for a period of approximately 10 seconds, followed by a
brief "dark phase", then one of the following flash codes will indicate the cause of the fault. This indication will repeate
as long as the lockout reset button is not reset.
