Priva Compass - EC-DSS Interface; EC-DSS Interface Operation

The use of 5 dosing channels with GevaSol valves requires at least 100VA. Therefor the
graphic above includes a 300VA transformer. The 24 VAC transformer from the Compass
cabinet can be used, but this means there is no output power available for other components.
