Channel trending
Touch input on an input channel opens the trend display. This
visually shows the progress of the measurement and indicates
the current system status (alarms/errors). The "Channel" tabs
can be used to switch from this view to the other channels of
the selected REGARD 3900 controller.
This change is only possible within the channels of a controller.
The "Close" touch button leads back to the system overview. A
cursor can be set to display historical measured values.
Navigation is also possible using the zoom functionality and
the arrow keys. To analyse the area around the zero-point, the
trend also shows 10 % of the full scale value in negative.

Status indicator
When a channel enters the alarm or error state, the RVP 3900
clearly indicates this by the affected channel tabs flashing
yellow or red and a clearly audible alarm tone. The higher-level
tabs show the status of the respective system. Alarms are
shown in red and faults in yellow. An alarm message always
has priority over fault messages. If there is a communication
error to the system, it has top priority. In the event of a
communication error, the entire image background of the
system is also displayed in yellow. The colour of the event
flashes alternately with the standard colour of this button. Blue
indicates that the system is currently selected for viewing. Grey
symbolises systems that are not selected.
The narrow progress bar and the area for the acknowledge
button flash when there is an alarm or fault in one of the
connected systems. Here, too, alarm messages have priority
over fault messages.
For the individual channels, the tile of the channel is displayed
red (alarm) or yellow (fault) in the event of an alarm or fault.
Here, faults have priority because the individual channel is not
ready for measurement in the event of a fault. Any state is
represented symbolically in the tiles, even if different states
such as "alarm" and "fault" occur at the same time.
The audible alarm can be switched off by pressing the "Horn
off" button. Under the operator user view (or higher), it is
possible to acknowledge the alarms here. All connected
REGARD 3900/3910 systems are acknowledged.
