The second essential value is the water level of our aquarium, which requires intervention drops below a certain amount of water. In this
case, a level sensor is used, which closes a digital contact at a filing level of 80%:
This input clearly indicates that the water level has dropped, but not why it happened - normally this will be caused by natural
evaporation.
The cross reference:
Using the matrix, you can now handle both events in conjunctionto each other:
In this case, marker 1 would be set active if both inputs are closed at the same time: The idea is that a glass crack alarm is present AND
the level has dropped below 80% - in this case someone should be informed at once.
In the Events menu, fsearch for Alarm Marker 1:
In diesem Beispiel soll eine SMS geschrieben werden, sobald beide
Bedingungen erfüllt sind:
In this example, an SMS should be sent as soon as both conditions are
met:
At the moment the marker is activated, the CS141 will issue an emergency
SMS if a GSM modem or alternatively an IP modem is available. Thus,
both individual input events have been directly connected, other jobs are
possible that will be repeated as long as this marker status is present.
The marker status will be terminated with two basic conditions:
1. The water level has been corrected
2. The glass damage has been fixed
Since these two conditions are coupled by an AND link, this marker is triggered only when both conditions are met.
Using several marker
This marker can handle two basic problems:
A dropping water level below 80% and some kind of cracking glass. And yes, if this happens simultanously, it is possible that water
leaks. Due to the fact, 20% water inside an observation room can be very many water, a third sensor may be usefull:
This sensor will find water or increased humidity levels at visitors observation room - something that can only be caused by a cracked
aquarium windows (or something visitor- caused).
With the matrix settings, a second sensor can be configured:
This marker defines that there is a glass breach alert present and water is found at visitors observation room., dass ein
Glasbruchproblem vorliegt und im Besucherraum zudem Wasser auftritt.
