Extraneous light / advanced ignition
During the pre-ventilation and/or pre-starting phase there shall
be no flame signal. Should the signal be present, for example
for advanced ignition due to bad tightness of the electrovalve,
external lighting, short-circuit in the photo-resistance or in the
connecting cable, a breakdown in the flame signal amplifier,
and so on., when the pre-ventilation and safety time has
elapsed, the control-box brings the burner to the emergency
stop and cuts off fuel inflow even during the safety time.
No flame
If there is no flame at the end of the safety time, the control-
box stops the burner immediately.
No flame during operation
If there is no flame during operation, the control-box cuts off
fuel and automatically repeats a new starting program: once
the "t4" time has elapsed, the starting program is over.
Every safety stop of less than 1 second switches off voltage
to terminals 3 - 8 - 11: and to terminal 10, it is possible to
provide a remote signal of emergency stop. Resetting of the
control-box is possible after approx. 50 seconds of emergency
stop.

PREPARATIONS FOR START UP

Control that the nozzle (60° spray angle) applied is suitable for the boiler popentiality.
The table shown delivery rates in kg/h of light oil with respect to the nozzle size and the pump pressure (normally 22
bar for the 2nd flame). It should be remembered that 1 kg of light oil in equivalent to approximately 10.200 kcal. Make
sure that the return pipe in the tank has no obstructions, e.g. gate valves, closed plugs etc. Any eventual obstruction
would cause a breakage in the sealing surface situated on the pump shaft. Close the main switch and the boiler
thermostats in order to start up the motor and the ignition transformer and, after approximately 10 seconds, the
electric valve will out in and expose the photoresistant cell to a source of light until the burner stops (shut down).
When the pipelines have been filled up (and when fuel has come out of the nozzle), stop the burner and put the
photoresistant cell back in its seat.
Note: Should it be necessary to purge air, this can be done by loosening the special fitting which the pump is provided
with (see BT 8945/2). Do not illuminate the photoresistant cell before the electric valve has out in because, in
this case, the control box will go to "shut down".
