Electricalinstallation
Caution: (Exhaust air concept) :
In compliance with degree of protection IP67, an exhaust
air line must be installed in the dry area (control function A
and B).
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 fluctuations are greater,
the control parameters measured with the
X.TUNE function
are not optimum.
