Sensor/Actuator States - LEGRAND Raritan PX3TS User Manual

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.
See Yellow- or Red-Highlighted Sensors
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."
State
normal
below lower critical
below lower warning
above upper warning
above upper critical
alarmed
unavailable
(on page 264).
Description
▪ For numeric sensors, it means the readings are
within the normal range.
▪ For state sensors, it means they enter the
normal state.
"R" < Lower Critical threshold
Lower Critical threshold <= "R" < Lower Warning
threshold
Upper Warning threshold < "R" <= Upper Critical
threshold
Upper Critical threshold < "R"
The state sensor enters the abnormal state.
▪ Communication with the managed sensor is
lost.

▪ DX2 DX, DPX2 or DPX3 sensor packages are
upgrading their sensor firmware.
