Selecting the correct supply pressure

A permanent deviation will occur if the supply pressure is less
than the outlet pressure stipulated by the electrical set point. The
electronics will reduce the power consumption and thus the max.
nominal width to prevent the ED12 from heating up.
CAUTION
Always select a supply pressure that is higher than the outlet
pressure.
