professional planning and execution!
If the drive converter system operates at rated operation, the coolant circuit can be done
in a series connection. It should be noted that the temperature is analog measured in the
slavemodulesandanerrorsignalisgivendigitallytothemaster.Thewaterreturnow
should always be attached at the master in order to display real temperatures.
