Service and maintenance
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.
