Warning no. Warning text
001 (HP)
101 (ÜP)
O
2
offset voltage in the air too large or too small
/1 - 29999 Trigger value of the O
2
offset voltage in the air (x0.1 mV)
002 (HP)
102 (ÜP)
CO offset voltage in the air too large or too small
/1 - 29999 Trigger value of the CO offset voltage in the air (x0.1mV)
003 (HP)
103 (ÜP)
O
2
temperature too large or too small, was not assumed
/1 - 29999 Trigger value of the O
2
temperature (x0.1 K)
004 (HP)
104 ÜP
CO temperature too large or too small, was not assumed
/1 - 29999 Trigger value of the CO temperature (x0.1 K)
Help:
When calibrating the O
2
electrode in CO containing flue gas the O
2
sen-
sors’ Kelvin value moves outside the permissible range
(< 800 ... >1200 K). The warning WH004 or WH104 is indicated CO
temperature is too high/too low.
The calibration have to be repeated on another point of O
2
without CO in
the flue gas.
005 (HP)
105 (ÜP)
CO scaling
/1 CO value not assumed, CO setpoint value too small
/2 CO value not assumed, division by zero
/3 CO value not assumed, calibration scaling factor outside of the valid
range
Help:
CO sensor worn/poisoned. Exchange the probe.
/4 CO value not assumed, value is zero
010 (HP)
110 (ÜP)
