14ABB i-bus ® EIB / KNX CommissioningFig. 11: Parameter window “Channel A – Definition of the measuring range”The following 4 parameters are dependent on the Send output value asparameter. The preset values change depending on which byte value is set.In addition, the Factor parameter appears if the 2-byte [EIB floating point] or4-Byte [IEEE floating point] option is selected.The following description is an example for all the byte values that canbe set.Lower measuring limit in x % of the upper limit of effective rangeOptions: 0...100Upper measuring limit in x % of the upper limit of effective rangeOptions: 100...0These two parameters are used to set the Lower and upper measuring limitin x % of the upper limit of effective range. When the value exceeds or fallsbelow the set lower and upper measuring limit, the “Measured value outsiderange – Channel A” communication object sends a “1”. When the measuredvalue is between the two limits again, the communication object sends a “0”.What is the upper limit of effective range?The upper limit of effective range is the maximum voltage, current, resis-tance or temperature value which is set in the “Sensor output” parameter,e.g. a sensor with a signal output of 0 – 10 V has an upper limit of effectiverange of 10 V.3.2.2.1 Definition ofthe measuring range
