Heater operations and safety mode
* If the fuel pump
1. If the fuel pump fails to ignite within 90 seconds after
fuel pumping starts, the start procedure is repeated
as described. If after a further 90 seconds fuel pumping
the fuel pump still fails to ignite, the heater is switched
off in fault mode.
The controller is locked after a certain number of failed
starts.
2. If the flame does out by itself during operation, firstly
a new start is activated. If the fuel pump fails to ignite
within 90 seconds after fuel pumping has started
again, the heater is switched off.
3. If the heater is overheated (lack of water, poorly vented
cooling circuit), the overheating sensor triggers, the
fuel supply is interrupted and the heater is switched
off.
4. The heater is switched off if the lower or upper voltage
limit is reached.
5. The fuel pump does not start when the glow plug is
defect or electrical lead to the dosing pump is
interrupted.
6. The fan motor speed is monitored continuously.
If the fan motor does not start up, is blocked or if the
speed falls below 40% of the nominal speed, the
heater is switched off in fault mode after 60 seconds.
7. It is possible to diagnose the system by connecting
the diagnostic device to controller. For details, refer
to the “Diagnosis Procedures” section.
[Emergency shutdown]
If an emergency shutdown -EMERGENCY OFF- is
necessary during operation, proceed as follows;
• Pull the fuse (Ef6: 20A) out.
• Disconnect the heater from the battery.

2. Mounting spring
Check control and overheating sensor
Check the control and overheating sensor with a digital
multimeter. If the resistance according to the changes of flame
sensor temperature is out of specified values, the flame sen-
sor is defective.
