CAUTION
Increased sound pressure level
Changes to the sound absorber of the positioner or the mounting of pneumatic components
or pneumatic options on the positioner can cause a sound pressure with a level of 80 dBA to
be exceeded.
● Wear suitable hearing protection to protect yourself against hearing damage.
E.1 Booster introduction
In order to shorten the travel times, use a booster between the positioner and actuator.
Note
Positioner with booster, double-acting
If the supply pressure PZ fails, the booster changes the failure behavior of the positioner. The
position of the valve is random.
The booster has no effect in the event of an electrical power failure.
