Caution: (Exhaust air concept):
In compliance with degree of protection IP67, an exhaust air line must be installed in the dry area.
Keep the adjacent supply pressure always at least 0.5 – 1 bar above the pressure which is required to
move the actuator to its end position. This ensures that the control behavior is not extremely negatively
affected in the upper stroke range on account of too little pressure difference.
During operation keep the fluctuations of the pressure supply as low as possible (max. ±10 %). If fluctua-
tions are greater, the control parameters measured with the X.TUNE function are not optimum.
