(WITH LIMIT SWITCHES)
9.1 Introduction
9.1.1 General description
ND9200F can be equipped with limit switches.
ND9200F/K2_ has two microswitches, ND9200F/I__ has
two inductive proximity switches and ND92_F/B_ has two
bus powered mechanical micro switches. Limit switches
are used for electrical position indication of the valves
and other devices.
The switching points may be chosen freely.
9.1.2 Markings
The limit switch is provided with an identification plate
sticker, see Fig. 27. Identification plate markings from
top to bottom are:
❑ Type designation
❑ Electrical values
❑ Temperature range
❑ Enclosure class
❑ Conduit entry
❑ Manufacturing serial number
The type designation is described in Chapter 14.
