Trolex AirXD Alarms

Modified on Thu, 29 Feb at 11:33 AM

The AIR XD offers two user configurable alarms. Each alarm requires four parameters to be selected and configured:

1. Assigned a PM size/channel (PM1.0, PM2.5, PM4.25, PM10.0 and TSP)

Select one of the four configured PM sizes or TSP as the alarm source.

2. Assigned a data source/channel

Select whether to act on live data readings or one of the pre-configured averages (15 minutes to 8 hours).

3. Assigned a threshold (μg/m3 and mg/m3)

Set the value at which the alarm will trigger (1 μg/m3 to 9,999 μg/m3 or 0.1 mg/m3 to 6,553.5 mg/m3.

4. Assigned latching of non-latching behaviour

Choose whether the alarm stays active once the fault condition is cleared or is self-clearing (non-latching). For non-latching selections, alarms will be cleared but the event will be logged.

Note: Once the alarm is triggered, the corresponding relay will then switch, and an alarm message is displayed on screen. All alarms are logged in the AirXD event log
