Figure 4–15: MONITORING/STATISTICS Menu
In the menu, a distinction is made between first-, second- and third-priority
errors. The pertaining parameters are listed under the respective priority. Each
parameter is preceded by an error counter.
Errors are indicated in error seconds; the counter is incremented by 1 for each
second in which an error of the respective parameter occurs at least once. At a
maximum of 99 error seconds, the counter stops until the monitoring is cleared
(refer to MONITORING/CONTROL Menu on page 4–14).
If the monitoring of a parameter is switched off (see MONITORING/REPORT
Menu on page 4–13), the respective error counter in the LCD indicates [––]. In
the OSD, the deactivated parameter is marked in a darker color (for example,
gray instead of white).
If an error occurs for a monitored parameter, the pertaining front-panel LED
comes on for 1 second and an asterisk (*) is displayed in front of the parameter
name. In the OSD the error counter is displayed in red. If error conditions are no
longer met after one second has expired, the counter is displayed in yellow and
the asterisk in front of the parameter name is cleared.
In the ‘ELAPSED TIME’ field of the OSD, the monitoring time is displayed in
days, hours, minutes, and seconds.
