Hardware settings
The safety concept of the compact flame controller is
based on two-channel signal processing.
The evaluation channel processes the flame signal under
processor control so that the settings can be changed by
the BFI software.
The safety channel is configured with SMD technology.
Settings can only be changed on the printed circuit board.
5.3.1
Safety switch-OFF time of the safety channel
The safety switch-OFF time of the safety channel (hard-
ware) is set by means of a jumper. The settings are as fol-
lows:
Jumper 1 bridged: 1 second
Jumper 2 bridged: 3 seconds
Jumper 3 bridged: 5 seconds
If a switch-OFF time of 2 seconds is required, the jumper
must be inserted in position 2 (3 seconds) and the switch-
OFF time of the evaluation channel set by software to 2
seconds (see Handbook HB CFC Com1 EN). The shorter
switch-OFF time of the two channels always takes priority.
The safety switch-OFF time during operation (shut-off
time) is also dependent on the software setting (see
Handbook HB CFC Com1 EN)!
