7.3 Alarm Setup
Individual process alarms can be activated and configured for the selected measurand/gas in the alarm
setup accessible from the measurand related menu. Limit values and hysteresis can be set. Only one
alarm can be set per gas.
A triggered alarm is signaled by a flashing of the measured variable on the display. Alarms can be used
to switch relays.
7.3.1 Selection of alarm groups
In the first display line the <ENTER> key can be used to select the alarm group to which the set alarm

• Alarm 2: The alarm belongs to alarm group 2
• Alarm 3: The alarm belongs to alarm group 3
• Alarm OFF: The alarm is switched off.
