Motor protection switch
The pump motor is protected from overload by a motor protection switch. This
switch cuts out the motor in the event of overload. If the motor cuts out repeatedly,
locate and eliminate the cause of the fault.
Replacement and inspection work may only be performed by trained personnel.
Flame monitor
The system is fitted with a flame monitor.
The flame monitor prevents fuel being injected if combustion is not taking place.
There is a temperature sensor in the exhaust chimney of the combustion chamber,
and it is connected to the central electronic control circuit.
The burner is switched off if the temperature in the chimney has not reached 100°C
within 37 seconds of the burner being started, or if the exhaust gas temperature
drops below 100°C for longer than 2 seconds while the engine is in operation. The
magnetic fuel valve is cut-out. The message "FLA" for flame monitor is shown on the
display of the control panel.
Call customer service if the system cuts out repeatedly because of the flame
monitor.
