not exceeded. Otherwise, the positioner and/or the actuator may be
damaged.
•
The positioner must be supplied with instrument air exempt from oil,
water and dust according to DIN/ISO 8573-1, Class 3
- Purity: max. particle size 5 µm, max. particle density 5 mg/m
- Oil content: max. concentration 1 mg/m
