Digital inputs
In addition to analog inputs, the SENSORMANAGER can manage up to 4 ditigal inputs. The inputs
Diese Eingänge werden entsprechend der Konfiguration auf Aktiv geschaltet und können im Alarmverhalten als NC (Normally Closed)
oder NO (Normally Open) – Kontakt definiert werden.
Linking digital inputs
The marker only looks whether the result of the digital input is "High (On)" or "Low (Off)" - The type of
contact is unimportant for the marker. like the analog inputs, name of the digital input will be shown by
mouse over action. The linking of the digital inputs follows the same principle as with the sensors.
Linking digital inputs and analog sensors
Simply select the appropriate digital inputs with the analog inputs. Press Apply to save the setting and
restart the services for the sensors.
Switching an output
Outputs will be switched in case of conditions met via the defined alarm markers:
In contrast to the markers, however, no pre-alarms are used - if the marker is set to high, the output will be switched depending on its
switching logic. The CS141 matrix provides combining up to 8 markers individually and assign them with an AND / OR combination. The
output will be switched:
1. As soon as only one of the configured marker are set to high. („OR“)
2. As soon as all configured marker are in high state („AND“)
Fallback of the output to normal state
the output is only switched as long as the condition has been fulfilled exactlyhereby the corresponding logical link will decide which
condition leads to the drop of the output:
In a restrictive AND operation, only one marker to off will force the output to off.
With an OR operation, the output remains at ON state until each marker is turned off.
Keep in mind that the markers conditions for an on/off state will not be checked by output switching control – This control only checks
logically the markers state and act according to it.
Tutorial: Example scenario: aquarium
In this simple example the cross reference between a cracked disc and a leaking aquarium wil be described. It shall show you how
markers, inputs and outputs will be linked and work together. The total scope of scenarios can reach very high complexity and fitted
even to very custom problems….
Huge aquariums with large glass panels are dependent on ensuring the structural integrity. If a glas panel is damaged or cracked, a
corresponding alarm must be issued automatically. For this purpose, the sensor manager offers a digital input:
The method this crack sensor uses to detect a cracked glass is a secondary question as the SENSOR MANAGER also supports the
connection of third-party sensors. If necessary, connect an additional relay box to each sensor manager input: With the SM_IO box,
managing all 4 inputs and outputs is made intuitive.
In this scenario, a glass crack sensor would close a switch and thus report a problem to digital input 1.
