(Version : 02.02.2010 10:36) p. 40/50
The main module is
in alarm mode, due to
alarm thermo-probe
activation
(overheating of the
main module’s fuel
delivery pipe)
After the main unit is cooled
down to ambient temperature, the
reason for this emergency
situation should be clarified and
necessary steps should be taken in
order to sustain operating
conditions for the burner. The
burner should be restarted;
The burner does not
run and a “START”
signal is present (the
“START” indicator is
active
Check if the control board is in
alarm mode – see following table
with operating and alarm
indication
Safety fuses are
broken due to
emergency short
circuit
This check-up operation should
be performed by authorized
technician only : check each
f
use
s
tatus and replace if necessary
with appropriate one (Attention:
safety fuses F3 and F4 are fast
reacting);
Low quality fuel Fuel replacement is
recommended, most probably the
moisture content is higher than
required for nominal operation of
the burner – see the requirements
in the fuel properties table;
8. The flame looks
“opaque” and
smoke is
observed at the
exit of the
chimney
Inappropriate
operating parameters
adjustment
It is necessary to perform
operating parameters adjustment
and achieve efficient combustion
process – this operation should be
p
erformed by trained authorized
personal only;
Incorrect photosensor
positioning
Change (i.e. slightly rotate or
even axially move) the position of
the photosensor
The external surface
of the photosensor is
dirty
Clean the transparent section of
the photosensor by careful
cleaning – do not use solvents
9.
The ignition
process of the
fuel is
successful, but
the unit could
not reach stable
operating mode
The photosensor is
gone – its working
surface is damaged
and overheating
zones are observed
It is necessary to replace the
photosensor – it should be
p
erformed by authorized
technician only
