][ min/h ]: resending time.
➢
Notification of No Alarm [ No / Yes ]: indicates if the alarm object should be
sent (with inverse value of the configured action) once the alarm is
deactivated.
➢
Hysteresis Under the Limit : defines a dead band for alarm deactivation.
When the alarm is active, it will not be deactivated until a value below the
limit minus hysteresis is reached. The units will coincide with those
configured for the chosen channel/phase.
Lower Limit [ Enabled / Disabled ]: allows the alarm to be triggered if a limit
value is lowered. Enabling this parameter will display the object
“Alarm n:
Low_____
” and the following parameters will be displayed:
➢
Limit : sets the value below which the alarm will be triggered. The units will
match those configured for the chosen channel/phase.
This limit can also be set via the object
“Alarm n: Set Lower Limit”
.
➢
Action [ Send 0 / Send 1 ]: set the value to be sent through the object
“Alarm
n: Low_____
” when the alarm is triggered.
➢
Periodic sending [ Enabled / Disabled ]: activates or deactivates the periodic
resending of the object while the alarm remains active.

Hysteresis Above the Limit : defines a dead band for alarm deactivation.
When active, the alarm will not be deactivated until a value over the limit
plus hysteresis is reached. The units will coincide with those configured for
the chosen channel/phase.
