Filter: The time in hour:minute:second during which the condition must stay TRUE, before the
call is generated.
Filter can be tested either during both transitions or only during the transition selected
(see chapter 7.5.2)
Handling:
The handling option allows blocking each alarm condition, manually or automatically.

Enabled: alarm condition always active.

Disabled: alarm condition always de-activated.

PowerF: alarm condition disabled when there is a main power failure.

DisAla: alarm condition de-activated when the system variable ‘DisAla’ = 1.
Severity: Each alarm can be assigned a level of severity: Low, Normal or High. When several
alarms are still present in the queue and then not processed yet,
TB
OX
LT2
generates the calls according to the highest severity.
Notify End of Alarm: When the alarm condition is finished, the alarm is automatically re-sent to the
same recipient with the same message preceded with a prefix (see chapter 7.5.2).
Example: for a ‘positive edge’ alarm, it is when the Tag returns to ‘0’.
It is also useful when the alarm condition is active when
TB
OX
LT2
starts up. When ‘end
of alarm’ is checked, an alarm is automatically generated when the alarm condition
disappears (see illustration chapter 12.8: Alarms table)
