Operation
The following chapter describes the operation of the positioner.
4.1 Display
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 contents of the display depend on the
selected operating mode (see chapter 4.3, page 92)
.
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 4-1 shows you the various display options. The meaning of fur-
ther display capabilities is detailed in chapter 4.3 page 139.
4.2 Input keys
The positioner is operated by three keys (figure 4-2, page 91) 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.
