SIPART PS2 PA Manual

The following chapter describes the operation of the positioner.
The LC display has two lines whereby the lines have different
segmentation. The elements of the top line consist of 7, those of the
bottom line of 14 segments. The display depends on the selected
operating mode (see chapter 4.3, page 94)
NOTE
If the positioner is operated in ranges with temperatures below --10 °C
the liquid crystal display becomes sluggish and the display refresh rate
is reduced considerably.
Figure 54 shows you the various display options.
The meaning of further display capabilities is detailed in chapter 4.6
page 122.
The positioner is operated by three keys (figure 55, page 93) the
function of which depends on the selected operating mode. In the
explosion proof version of the positioner the input keys are underneath
a key cover which can be lifted up after loosening the cover screw.
NOTE
The input keys of the explosion proof version must be covered to
prevent liquid getting in. The IP66/NEMA4x degree of protection is not
guaranteed when the housing is open or the key cover is open.
The housing cover must be removed to operate the keys in the normal
and intrinsically safe versions of the positioners.
