for optional phase
independent versions: 0.5 µA
for phase dependent
versions: 0.9 µA
Response time on: > 0.2 s
Response time off (T
FR)
:< 1 s
Hot surface ignition
Free contact: 230 ... 240 Vac, 2 A, cos ϕ = 1
24 Vac, 2 A, cos ϕ = 1
110 ... 120 Vac, 2 A, cos ϕ = 1
WARNING
Hot Surface Igniter (HSI) needs to be supplied from a
floating winding of a transformer in order to
quarantee reliable flame detection.
Length flame sensing cable
1 m max.
Length of wiring for external components
1 m max.
Remark
Optional integrated flame relay available with safe separation
or opto coupler with safe separation.
N.C. contact of flame relay has no safe separation.
WARNING
Opto coupler interface needs a debounce time > 20
ms in order to prevent noise caused by transients on
mains.
