3.8 Configuring gas level alerts
Figure 30 Alert limits settings page
Configure gas level alerts on the Alert limits settings page. There are separate rows for each
individual gas level alert. Alerts for rate of change (ROC) values are on their own tabs. By
default, all gas level alerts are o.
1. Connect to the user interface as the Admin user.
2. In the user interface, select Settings > Alert limits.
3. For each alert you want to configure:
a. Change to the tab that shows the alert you want to configure.
b. Enter the Caution Limit in ppm. This is the limit that triggers a gas alert with caution
severity.
c. Enter the Alarm Limit. Alarm limit should be higher than the caution limit, except
when configuring a minimum limit alert for total gas pressure (TGP).
d. If the alert is for the total gas pressure (TGP) value, select if you want the limit value
to be a maximum limit (alert active when value is above the limit) or a minimum limit
(alert active when value is below the limit).
e. Set the alert to On to enable it.
It is possible to have only caution or alarm severity active. If you leave a limit value empty
or enter a zero, the corresponding severity will not be active for that gas level alert.
