Sensor/Actuator States - LEGRAND Server Technology PRO3X User Manual

• •
They show one of the managed states.
• • For managed 'numeric' sensors, their readings are retrieved and displayed. If any numeric sensor is
disconnected or its reading cannot be retrieved, it shows "unavailable" for its reading.
▶
Unmanaged sensors/actuators:
• •
PRO3X does NOT communicate with unmanaged sensors/actuators.
• • Unmanaged sensors/actuators are listed only when they are physically connected to PRO3X.
They disappear from the web interface when they are no longer connected.
• •
They do not have an ID number.
• •
They show the "unmanaged" state.

Sensor/Actuator States

An environmental sensor or actuator shows its real-time state after being managed.
Available sensor states depend on the sensor type -- numeric or state sensors. For example, a contact
closure sensor is a state sensor so it switches between three states only -- unavailable, alarmed and
normal.
Sensors will be highlighted in yellow or red when they enter abnormal states.
An actuator's state is marked in red when it is turned on.

Managed sensor states:
In the following table, "R" represents any numeric sensor's reading. The symbol <= means "smaller
than" or "equal to."
