Fuel level indicator service
Each time when fuel silo is filled to required
level it is necessary to press and keep the
knob in main window. Following info will
appear:
Fig. 13 Operation of fuel level indicator
Once YES has been selected and confirmed,
fuel level is set at 100%. Fuel may be
replenished at any time without a need to
wait for complete empty fuel tank. Replenish
fuel always to the level corresponding to
100% and confirm achieved 100% level by
keeping the knob pressed for a while!
Description of activity
The controller measured fuel level on the
basis of its current consumption. Factory
settings will not always correspond to actual
fuel consumption , so to work correctly this
method needs level calibration by controller’s
user. No additional fuel sensors are required.
Calibration
If the service parameters of the boiler:
Feeder Efficiency and Tank Capacity are
properly set, calibration is not necessary -
regulator should properly calculate fuel level.
But, if the fuel level calculations are wrong,
calibration has to be performed. For this
purpose, fill the fuel tank to the level
corresponding to its full load and set the
parameter
Fuel level calibration at 100%.
This parameter is available in MENU

Fuel level calibration .
Indicator in the main window is now set at
100%. Pulsating fuel level indicator means
calibration process is in progress. The
indicator keeps pulsating until minimum fuel
level has been set. Check regularly the
decreasing fuel level in the tank. Once the
level dropped to the minimum - set the value
of
Fuel level calibration at 0%.
Change of service parameter: Tank
Capacity cancels the calibration of
fuel level - then, the level is
calculated on the basis of the
parameters:
Feeder Efficiency and
Tank Capacity .
Set fuel level at 100%?
YES NO
