Icon Name Value Explanation
70:
AC signal 0 ... 2,500 mV Current effective value of amplified signal
20:
Switch-on
level
0 ... 2,500 mV Switching threshold for "flame ON"
05:
Switch-off
level
0 ... 2,500 mV Switching threshold for "flame OFF"
07:
Amplification
Sensor 1
1 ... 13 Amplification level of the signal
-Single sensor UV or IR
-Double UV sensor
08:
Amplification
Sensor 2
1 ... 13 Amplification level of the signal IR- Double
sensor only
12:
Weighting 0 … 100% Signal part of sensor 1 (UV)
- Double sensor only
06:
Frequency 10 ... 110 Hz
5 ... 160 Hz
Lower limit frequency as of which the signal
is analysed.
11:
Safety time 1 ... 5 sec FFDT, maximum time before the flame
relays are switched off after the non-
appearance of the flame signal
10:
Switch-off
time
0,3 ... 5 s Time before the flame relays are switched
off after the non-appearance of the flame
signal
09:
Recovery
time (integra-
tion time)
0,2 ... 5 sec Time for the development of the full switch-
off time of the flame relays if the flame sig-
nal is not emitted for a short period
24:
Switch-on
time
0.2 ... 5.0 sec Switch-on time of the flame relays after the
appearance of a very high-quality flame sig-
nal – effective only in switch-on/startup
25:
Level of sup-
pression
0.3 ... 5.0 sec Level of suppression of portions of the sig-
nal that do not belong to the signal of the
intended flame – effective only in switch-on/
startup
