alarm will be automatically activated, switching the output status (OFF to ON). As before, any
action over the output will be ignored until the alarm is deactivated. See figure 3.9.
Figure 3.9. Cyclical monitoring example
Response:
set the response of the actuator channel output when the alarm is
activated:
No change
ON
OFF
Flashing: 3 drop-down boxes are shown to configure the ON Duration, the OFF
Duration and the number of repetitions of the flashing sequence.
Deactivation:
there are two different methods to deactivate an active alarm:
Normal: depending on what was parameterized on “Trigger Value”, the alarm will
be deactivated when the actuator receives a “0” or a “1” through the alarm object.
Frozen: with this method, a normal deactivation will be applied, but the alarm will
not be deactivated until the actuator receives, besides, a “1” through the object “[OX]
Unfreeze Alarm”. This method makes the channel output remains blocked even when
the alarm status has finished; in this case it will be necessary that the output is
manually enabled from another point in the installation.
End (reaction when alarm ends):
this parameter sets the output response in one of
these statuses when the alarm finishes:
Output status
“[OX] Alarm”=1
“[OX] Alarm”=0
“[OX] Alarm”=0
