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 display depends on the selected
operating mode (see chapter 4.3, page 76)
.
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.
4.2 Input keys
The positioner is operated by three keys (figure 4-2) 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 IP65/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.
