3 Operating
gas-net
devices
This chapter’s objective is to give you an understanding of the basic operating
and menu structures of
gas-net
devices.
As already mentioned, all devices of the
gas-net
family have a uniform
appearance and a comparable menu structure.
This means for the user: If you have operated a
gas-net
device once, you will
also be able to operate all other device types without any problems.
According to our philosophy of how to parameterise
gas-net
devices, they are
adjusted by means of a PC or laptop and not via the operator panel. The device
operation via the operator panel mainly serves the indication of the most
important information on the display. The content of the operator interface on
the display depends on the individual
gas-net
device type.
3.1 The keypad
The keypad of
gas-net
devices consists of a numeric keypad for the entry of
numbers, minus sign and decimal point keys and a group of four navigation
keys. With these keys, you may move within the menu structure and invoke
menus and displays. In some cases you may also trigger actions or change
values via the navigation keys.
The illustrat
ion below shows an overview of the keys’ meanings. The exact
context-related meaning of each navigation key will be explained in connection
with the menu structure in Section 3.4.
