● You can use three buttons to operate the positioner.
● The function of the buttons depends on the mode selected.
● In a positioner with a flameproof enclosure, the buttons are protected with a cover. The
button cover can be opened after unlatching the locking screw.
Note
Key cover
In positioners with flameproof enclosures, the button cover prevents liquids from seeping
through. The IP66/NEMA 4x degree of protection is not ensured when the enclosure or
the button cover is open.
You have to remove the enclosure cover to operate the buttons of the basic device or the
"intrinsically safe" version.
Note
Degree of protection
The IP66/NEMA 4x degree of protection is not ensured as long as the positioner is open.
