Parameters
4 .2 Flame control
4 .2 .1 Burner flame signal
Parameter 01
Flame signal of the burner, display in µA, measuring range:
0 – 30 µA.
4 .2 .2 Switch-off threshold of the flame amplifier
Parameter 04
The sensitivity at which the burner control unit still detects a
flame can be set between 2 and 20 µA.
Example: In the case of UV control with the UV sensor UVS,
the signal of the burner to be monitored is influenced by other
burners.
The set value can be increased via a potentiometer in the lower
section of the housing so that only the flame of the system’s
“own” burner is detected.
The measured flame signal of the system’s “own” burner should
be at least 3 µA (empirical value) higher than the set switch-
off threshold.
