MAIN CONFIGURATION
3.1 Alarms
There are 4 concentration alarms for each measured component on the 2500 series,
and these are called ‘AL1’, ‘AL2’, ‘AL3’ and ‘AL4’. These must now be set up to suit the
measurement and control needs of the particular installation. Factory default settings
are 70%, 80%, 90% and 100% fsd respectively, and HIGH activation.
Each enabled alarm has four parameters which need to be set up:
i)
FREEZE to prevent alarms during calibration, or FOLLOW so that alarms may be
activated by calibration gases.
ii)
HIGH concentration alarm or LOW concentration alarm.
iii)
The concentration LEVEL at which the alarm is to occur.
iv)
The HYSTERESIS (dead band) of the alarm; this may be used to avoid ‘chatter’
if the typical sample concentration is close to the alarm level.
