Parameters
Input values to the flame sensor
Flame radiation input values required to generate the “FLAME IN” message:
– Spectral radiation range = 260 … 400 nm (FFS 05 UV1, FFS 05 UV1 Ex)
– Spectral radiation range = 210 … 380 nm (FFS 05 UV2, FFS 05 UV2 Ex)
– Spectral radiation range = 850 … 1200 nm (FFS 05-1, FFS 05-1 Ex)
– Spectral radiation range = 1200 … 2800 nm (FFS 05, FFS 05 Ex)
– Pulse frequency ca. 10…200 Hz

Safety period “operation” t Voff ≤ 1s
Other safety periods, e.g. acc. to t Voff ≤ 3 s
TRD 413, are adjusted internally
Dynamic parameters
Self-check clock pulse t pulse. abt. 1.5 s for safety period tVoff ≤ 1 s
t pulse up to 4.5 s for safety period tVoff ≤ 3 s
