6.11 CO monitor and CO controller
Refer to the manual of the measuring amplifier LT 3 and combination sensor KS1-D
prior to commissioning. The manual is available to download from the Weishaupt
Portal.
Components required for CO function:
Combustion manager W-MF 200 in version with FGR and CO (LMV52.4…)
O2 module
O2 sensor QGO20, for fuels Gas and fuel oil EL
CO measurement amplifier LT3
Combi sensor KS1-D for CO measurement
Resistance board for connection CO measurement amplifier to O2 module
The function CO monitor and CO controller must only be activated in conjunction
with O2 trim.
Depending on the combustion system it is possible that soot particles at the CO
sensor can produce a false CO signal when using fuel oilEL. In this case, only use
the function CO monitor or deactivate the CO function in the operating mode for
oil. On dual fuel burners, there is no limitation for gas.
A CO sensor and a measurement amplifier with digital output for signal evaluation
is required for CO detection. The digital output3 (Out3) of the measurement ampli-
fier is connected via a resistance board at the input of the combustion air sensor in
the O2 module [ch.3.3.24].
Digital output3 (Out3) is evaluated via the resistance board. In this case, the ABE
shows the switching status of the measurement amplifier via the combustion air
temperature.
Display Description
approx. 730 °C CO limit value exceeded.
Digital output3 (Out3) open, resistance at input approx. 3.6kΩ.
approx. 370 °C CO limit value not maintained.
Digital output3 (Out3) closed, resistance at input approx. 2.4kΩ.
The following settings have to be made in the configuration of the O2 module for
signal evaluation:
Set parameter MaxTempFlGas… to 850°C [ch.6.10.10]
In parameter SupAirTempSens select sensor Pt1000, see [ch.6.10.9].
A combustion air sensor is required for the calculation and display of the combus-
tion efficiency. In conjunction with the CO function, the actual combustion air
sensor is connected to inputX60:3/4. Parameter AirTempX60PT1000 (OEM
level) must be set to activated.
CO control is an extension of the O2 controller. The difference to the normal O2 trim
is that the O2 MinValue is set to approx. 0.25 … 0.5 percentage points below
the combustion limit. If CO control is only used for one fuel on dual fuel burners,
only the O2 MinValue for this fuel must be set below the combustion limit.
