1, 2, 3
Combustion chamber sensor fracture, measuring circuit from combustion
chamber sensor is open
sensor not connected
sensor defect
sensor cable defect
sensor temperature too
high
4
Negative draft input open, measuring circuit from negative draft measurement
open
signal incorrect
signal cable defect
signal too low
combustion chamber
leak
5
Negative draft input short-circuit, measuring circuit from negative draft measu-
rement is shorted out
signal incorrect
signal cable defect
signal too high
6
Negative draft pressure in boiler is not achieved
negative draft tube
disconnected
negative draft does not
change
Negative draft pressure
too low
connect sensor at input
Measure sensor (approx. 5mV at 125° C) replace
if required
replace sensor
sensor temperature above measuring range
(1100° C)
check polarity and signal (0-10V)
replace sensor
signal below 0V
check closure of boiler door
check polarity and signal (0-10V)
replace sensor
signal above 10V
connect up negative draft tube
Check negative draft tube for leaks. Check flue
gas tube for blockage.
Close boiler door, check tube to negative draft
sensor,
check whether boiler flue gas outlet is clear,
check whether condensation heat exchanger is
clear.
Make sure flue gas fan is running.
