ABB i-bus KNX
Parameters
7.11.1.4.3.1 —
Dependent parameter
Cable length, one-way distance
Options:
•
Via cable length: Cable error is compensated by entering the cable length.
Sets the one-way cable length of the connected temperature sensor.
The maximum cable length permitted between the sensor and device input is 100 m.
7.11.1.4.3.2 —
Dependent parameter
Cross-section of conductor, Value * 0.01 mm
Options:
The 150 option corresponds to a cross-section of 1.5 mm
The cross-section of the conductor to which the temperature sensor is connected is entered using this
parameter.
7.11.1.4.3.3 —
Dependent parameter
Cable resistance [total of fwd and rtn conductor]
Options:
This parameter sets the cable resistance level of the connected temperature sensor.
To measure the cable resistance correctly, the conductors must be shorted together at the end of the
cable and should not be connected to the analog input.
