CONCENTRATION ALARMS
The Model T360 includes two CO
2
concentration alarms. Each alarm has a user
settable limit, and is associated with an opto-isolated TTL relay accessible via the
status output connector on the instrument’s back panel (see Section 4.15.1.1). If
the CO
2
concentration measured by the instrument rises above that limit, the
alarm‘s status output relay is closed.
The default settings for ALM1 and ALM2 are:
Table 4-22: CO2 Concentration Alarm Default Settings

Set points listed are for PPM. Should the reporting range units of measure be changed
(see Section 4.8.2) the analyzer will automatically scale the set points to match the new
range unit setting.

To prevent the concentration alarms from activating during span calibration operations make sure
to press CAL or CALS button prior to introducing span gas into the analyzer.
