4.4.9.1 Hardware Alarms

There are four hardware fault related alarms that can be enabled and configured on the Alarms

Setup Page. These alarms are described in Table 12.

Table 12: Alarms Setup Page Hardware Alarms

Alarm

Explanation

IO Board

Communication

If the controller board is unable to communicate with the IO board, this alarm

will be triggered.

Laser

Communication

If the IO board is unable to communicate with the TDLAS module in the

AccuLase-GPA™ Optics/Sample Cell enclosure, this alarm will be triggered.

Bypass

Treats Bypass Mode as an alarm for remote enunciation that the analyzer is

currently in bypass and output results are not currently valid.

IO Board Diagnostic

If the hardware diagnostics determine there is a hardware related fault on the

analyzer’s IO board, this alarm will be triggered.

For each of these alarms, they can be enabled by placing a checkmark in the

Enable

box. Desired

Relay Actions

and

Solenoid Actions

can be associated with each alarm by placing checkmarks in

the checkboxes associated with the desired hardware actions for each alarm. The alarms can also

be set to be latched by placing a checkmark in the

Latch

checkbox for each alarm.

4.4.9.2 Calibration Alarms

There are two calibration alarms that can be enabled and configured on the Alarms Setup page.

These alarms are described in Table 13.

Table 13: Calibration Alarms

Alarm

Explanation

Slope Maximum

Change (Percent)

If the percentage difference between the previous calibration slope and the

newly calculated calibration slope is greater than the value placed in the Limit

field for this alarm, the alarm will be triggered. The new slope will also be

rejected and the analyzer will continue to use the previous calibration slope.

Offset Maximum

Change

If the absolute difference between the previous calibration offset and the newly

calculated offset is greater than the value placed in the Limit field for this alarm,

the alarm will be triggered. The new offset will also be rejected and the analyzer

will continue to use the previous offset.
