Operating Display

© Landis+Gyr AG
The ZxD400xT has the following three types of display:

Operating display
The values specified by the parameterisation are shown as a rolling
display in the operating display. The display is always in operating
mode when the display keys are not operated. The meter returns
automatically from the display list to the operating display after a
defined time. This display can consist of one or more values.

Display menu
By pressing the display key the display check is activated and from
there the user reaches the display menu by again pressing the display
key. From the display menu values of the display list, the load
profile(s), the event log etc. can be accessed. The display list, for
example comprises all values which appear in the display after
pressing a key. The values themselves and also the sequence can be
parameterised. The display keys permit scrolling up and down in the
list.

Service menu
The user reaches the service menu by pressing the reset key starting
from the display check. From the service menu, values of the service
list, the set mode etc. can be accessed. The service list, for example,
is an extended display list with additional values.
The values always displayed are considered the operating display. This can
be parameterised as a fixed display (only one value present, e.g. the pre-
sent tariff rate) or as a rolling display (several values alternate at a fixed
rate, e.g. every 15 seconds).

Limiting to active values in rolling operating display
It is possible by parameterisation to limit the rolling display to active values.
This helps to keep the rolling display clear, e.g. in meters with numerous
energy and demand registers.
