This feature needs firmware v2.02.18 and higher.


This setting ensures that the mA signal, when set to 4-20mA will not drop below 4mA.


Using the ASCII command ALO (ALO=4)or by using Datatemp Multidrop Software v6 you can set the mA output between 0 and 4mA for the Lower Analog Failsafe current - also when rear LED displays EUUU



Special Note:
