CONTROLS IN CASE OF OPERATION PROBLEMS
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 and 11: in the same,
by means of 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.
