Value
Numerical value and unit of measurement the current gas concentration.
The measured values are displayed in intervals, as long as they are
within the measuring range. If the measuring range is exceeded, the highes
t
value reached is retained. In the case of signal failure or an alarm
supression (during warm-up period of specific sensor types), dashes are
displayed instead of the measured value.
Gas type
Name of the measured gas
Status
Current status of the input
The status is updated at intervals and the following values can be displayed:
- Measure
- Calib. (calibrating)
- inhibit
- Overflow (Measured value above full scale)
- Signal Err. (Measuring value below measurement range, measuring value
missing)
- Suppressed (alarm suppression during warm-up period of specific sensor
types)
- 1st to 4th alams
- Free (sensor has not yet been installed)
Bar display
This display shows the measurement values as vertical bars, where each bar represents the
relative measurement value of an input with respect to full scale. The value range that can be
displayed is 0 ... 100%. The corresponding input number is displayed under each bar.
Figure 4-20: Bar display
In error-free operation with no alarms, the bars are shown in green. Any alarm will cause the
corresponding bar to change to red. If an input has the status message “inhibited” or “fault”
next to it, then its bar is shown in yellow.
When the bar for an input is clicked with the left mouse button, the current input data at the time
of the click is displayed. There is no graphic updating of the input data while this display is open.
