NOTICE:
The zeropoint and thus the direction of rotation of the stepping motor is only defined through the electrical
connection of the step motors (3 Nm or 9 Nm) with the BT 3xx.
When replacing the stepping motor, before the mechanical assembly, first the electrical connection to
the combustion manager BT 3xx must be made.
NOTICE:
Due to the programmed linkage control curves, the BurnerTronic BT 3xx may only be used for the burner
installed with it. An application of the BT 3xx for other or structurally identical burners is only possible by
resetting to this burner or by qualified engineers.
11.9 Configuring the gas/oil pressure switch
11.9.1 Gas pressure switch MIN
Set the gas pressure switch MIN to 50% supply pressure if the switch serves both functions (gas pres-
sure monitoring and tightness indicator), monitoring the pressure between the two main valves.
11.9.2 Gas pressure switch MAX
Set the gas pressure switch MAX to 130% of valve output pressure downstream of the gas control
damper.
This will prevent an overload if e.g. a change in the input pressure settings leads to pressure values
above that setting.
11.9.3 Air pressure switch
Set the air pressure switch to 80% of the lowest pressure difference at the burner.
NOTICE:
The pressure difference is measured with specific digital manometers.
11.9.4 Oil pressure switch MIN
Set the oil pressure switch MIN to 70% of the preset pump supply pressure at small load.
11.9.5 Oil pressure switch MAX
Set the oil pressure switch MAX to 130% of the highest return pressure at full load.
