3.3.2 Oil supply
Oil pump
The pump draws the oil through the supply line and carries it under pressure to the
oil nozzle. The pressure regulating valve keeps the oil pressure constant.
Solenoid valves
The solenoid valves open and close the oil supply.
Oil quantity regulator
The oil quantity regulator is driven by the combustion manager via actuator. An oil
metering vee slot in the oil quantity regulator changes the spill back quantity of the
fuel and thus the atomised quantity of the oil at the oil nozzle. The oil quantity regu-
lator has two metering slots. Each metering slot is matched with a specific oil
throughput. The identity code numbers on the shaft of the oil quantity regulator de-
note the oil throughput range.

Maximum oil pressure switch
The maximum oil pressure switch monitors the pressure in the return. If the value
set is exceeded, the burner switches off.
Minimum oil pressure switch (optional)
Depending on the burner application, optional equipment may be required for op-
timum operation [ch.12.3].
The minimum oil pressure switch monitors the pump pressure in the supply. If the
preset pressure is not achieved, the combustion manager initiates a lockout.
