Cleaning of the screens

The positioner is maintenance-free to a large extent. Screens are installed in the pneumatic connections of the positioners to
protect them from rough dirt particles. If there are dirt particles in the pneumatic auxiliary power supply, they damage the
screens and hamper the function of the positioner. Clean the screens as described in the following two chapters.
6.2.1 Positioners with Makrolon enclosure 6DR5..0, aluminum enclosure 6DR5..3, and
flameproof aluminum enclosure 6DR5..5
DANGER
Risk of explosion due to electrostatic charge
Electrostatic charges develop when cleaning the positioner in the Makrolon enclosure with a dry cloth, for example.
It is imperative you avoid electrostatic charges in the hazardous environment.
