8. TROUBLESHOOTING
1. Burner does not fire up the fuel:
Reasons:
• No fuel – check the fuel hopper and the feeder, if it is not blocked;
• Too small startup dose – check the startup dose;
• Burnt igniter – check the igniter;
• Defective drive motor - check motor thermistors;
2. Burner fires up but does not go into the first power
Reasons:
• Improper start-up dose – check the start-up dose;
• Dirty or faulty photosensor – clean it or replace it;
• Damaged outer thermostat in oil boilers or bakery ovens;
3. Photosensor checking.
See page 24.
Measuring readings:
• In darkness: 0-5%;
• In full light: 100%.
4. Overheating of inner feeder.
Reasons:
• Burner dirty with slag;
• Weak chimney draft – chimney exhaust fan should be used.
5. Damage of the feeder sensor– alarm can not be cancelled.
Reasons:
• The most common reason of this breakdown is damage of thermo protection of a sensor,
which results in overheating of measuring part. Despite burner cooling off, the fault can
not be cancelled, in this case the measuring sensor should be replaced. In order
to verify if the sensor is faulty indeed, its resistance should be checked, it should be
between 1-5 Ω. The resistance of a damaged sensor is about 100 kΩ.
6. Feeder overfilling.
Reasons:
• Wrong setting of the inner feeder in relation to outer feeder – increase capacity of inner
feeder (service menu / burner feeder);
• Gearmotor damage – replace the gearmotor;
• Wrongly adjusted interval of feeder work – this value should not exceed 20s. (service
menu / burner interval).
7. Blower damage.
Reasons:
• Blockade of blower blades – unscrew the blower cover and check if they are not blocked
mechanically;
• Check the voltage on blower wires;
• Check the capacitor of blower motor.
