The control box starts the burner fan, to carry out the prepurging
of the combustion chamber, and cheks the vent air pressure
through the air pressure switch. At the end of prepurging, the
ignition transformer cuts-in and generates a spark between the
electrodes. At the same time the two gas valves open (Vs safety
valve and Vl Low flame working valve). The total safety, in case of
missed ignition or casual burner's flame-out, is granted by a ionisation probe which cuts-in and sets the burner shut-
down within the safety time. In case of gas lack or a major pressure drop, the minimum air pressure switch shuts down
the burner.
SATRONIC DMG 972 CONTROL INFORMATION SYSTEM
The SATRONIC DMG 972 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.
