CAUTION
Humid environment/dry compressed air
Install the positioner in a humid environment such that the positioner shaft does not freeze
at low ambient temperatures.
Ensure that water does not seep through an open enclosure or an open gland. Water may
seep through if the positioner is not installed and connected on-site immediately and finally.
As a general rule, the positioner must be operated only with dry compressed air. Therefore,
use the customary water separator. An additional dryer is required in extreme cases. The
use of dryers is especially important when you operate the positioner at low ambient
temperatures. Set the Purge air switch to the "OUT" position when installing on the
pneumatic block, above the pneumatic connections.
