ELECTRODE / UV FLAME DETECTION
IN ACCORDANCE WITH STANDARD EN 298
Make a good connection of the ground of
AF1 to the body burner ground to ensure
correct operation.
The presence of the flame can be
detected by electrode or UV photocell
The use of UV Saitek photocells is
recommended. UVS10 or others are
however usually compatible.
-
must be employed only on
industrial application.
An
analog
output is available
to
monitoring the flame detection level.
Warning
: this output is NOT galvanically
isolated. Risk of electroshock, use only by
qualified electricians. Output signal scale
is from 0Vdc (0 uA) to 10Vdc (20uA)
approximately.
A galvanically isolated open collector
transistor output is available for fast signal
response. Transistor closes when flame is
detected. Vmax 24Vdc. max 100mA with
a 100 ohm resistor to limit the current that
can cause it to break.
Output relay can support a maximum load
of 1A 230Vac protect by internally fuse
