Make sure that the maximum permissible ambient and process media temperatures of the device are not exceeded.
•
Refer to the information in Chapter "Technical data (Page 38)".
CAUTION
Unsuitable compressed air

– Depressurize the actuator chambers.
– Switch off the supply air PZ.
– Lock the valve in its position.
Make sure that the valve has reached the pressureless state.
•
If you interrupt the pneumatic auxiliary power to the positioner, the pressureless position may only be reached after a
•
certain waiting time.
When mounting, observe the following sequence imperatively to avoid injuries or mechanical damage to the
•
positioner/mounting kit:
