The flame scanner is constructed such that there is potential separation between the power
supply (24 VDC) and the unit’s internal voltage (UB = 20 VDC / 5 VDC). The current output is
galvanically connected to the internal voltage.
The relay contact for the flame ON signal is delivered with a fuse, F2 = 0.5 A, slow, MST250, for
24 VDC voltage switches. If connecting other switch voltages, this fuse must be exchanged
accordingly.
