KRONOS 20 

The sensor housing is connected to the negative pin of the sensor 

output. In unfavourable conditions, ground circuit loops may hap-

pen that falsify the output signal considerably and thus disturb con-

trol activity. This must be taken into account during commissioning. 

It may be necessary to optimize the wiring or to use a galvanic sepa-

ration.
