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:
Pic. 14 Fuel level service.
After choosing and accepting „YES” fuel level
will be set for 100%. Attention: Fuel can be
refilled anytime, that means it is not needed
to wait till the silo is empty. However fuel
should be filled up to the level corresponding
to 100% and set the controller level by
pressing knob.
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
Fill the silo to the level which corresponds to
full level of fuel, then set value of parameter:
Menu – Boiler settings – Fuel level – fuel
level calibration – fuel level 100%
In main window the indicator will be set on
100%. The calibration process is marked
with a pulsating fuel level indicator. The
indicator will pulsate until programming point
referring to minimum fuel level. Decreasing
level of fuel in the silo should be monitored
constantly. When fuel level reaches expected
minimum, parameter value should be set this
way:
