while the time remaining for the boot se-
quence counts down in the display.
Line 4 is also used to display plain text status
information (errors, maintenance requests,
function checks or off-spec performance).
If such messages are active, line 4 alternates
between the messages and the parameter
selected for line 4.
Active messages are stored in an internal
buffer. If there is more than one message in
the buffer, the display will cycle through them.
Each message is not just shown in the display
as text, but also indicated by the appropriate
LED on the front panel and the activation of
the appropriate NAMUR relay (if a relay has
been assigned to that NAMUR function;
X-STREAM X2 series instruction manual).
Note!
There are also functions, that do activate a
relay or LED, but are not shown on the display
(e.g. concentration alarms). In such cases,
check the status menu for more information.
