Activating The function is activated via MD 10094
$MN_SAFE_ALARM_SUPPRESS_LEVEL. The function is already active when
standard data is loaded. This means that the alarms are displayed with a
reduced scope. Alarms 27000 and 300950 can be replaced by Alarm 27100
using MD 10094.
Limitation The MD is not included in the axial safety MD checksum. This means that the
function can be enabled/disabled at any time by changing the MD. During the
acceptance test, the alarm suppression function should be disabled in order to
be able to check the two-channel error detection. After the acceptance test it
can be re-enabled to reduce the number of alarms displayed to the final user.
