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
E
If there is no flame during operation, the control-box cuts off fuel
and automatically repeats a new starting program: once the "t4" time
N
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
G
same, by means of terminal 10, it is possible to provide a remote
L
signal of emergency stop. Resetting of the control-box is possible
after approx. 50 seconds of emergency stop.
