SATRONIC DLG 976
IONIZATION CURRENT
The minimum current necessary to operate the control-box is 1,5 µA (DLG 976), 3µA (LME11/21). When
the measurement of the current is required it is necessary to disconnect the lead to the probe and insert in its
place a microammeter for direct current (see fig. under).
SATRONIC DLG 976 CONTROL INFORMATION SYSTEM
The SATRONIC DLG 976 control is a micro-processor control which provides information about the cur-
rent operation 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.
FAULT DISPLAY MESSAGES
On burner failure the red LED is permanently illuminated for a period of approximately 10 seconds, fol-
lowed 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.
