NOTICE
Checking the Flame Shut-down on Fault:
Simulate a flame rupture or flame extinction by shunting off the fuel supply to the burner to be
monitored by the flame detector. Check that the signal for shutting-off the safety valve is trig-
gered off within the period of TS< 1 s (on safety period 'Operation' at tVOff = 1 s) after extinc-
tion of the flame.

For the IR compact flame detectors of the F200K1(2) IR-1 and/or F200K1(2) IR-2 types, take
into account the radiation effects characteristic of the combustion chamber. Consequently,
switch-off tests should be carried out when the boiler has reached operating temperature. In
particular, make sure that the sensitivity of the compact flame detector is increased only to
such a value required to safely and reliably monitor the flame throughout the operating range
of the burner.
