ZETA 4-20mA Transceiver
9
Set/query alarm threshold: upper alarm threshold and lower alarm
threshold. Once the detection value exceeds the set alarm threshold,
the device will immediately report an alarm. (Range 400~2000, unit
0.01mA, if the value is 0xFF 0xFF, it means there is no such threshold.
Note that the lower threshold should be lower than the upper
threshold when setting)
Set/Query the alarm threshold: To avoid repeated alarms caused by
the fluctuation of the device's collection value within the alarm
threshold, the default value is generally used, and there is no need to
set it.
Set/query alarm enable: Enable on means that the threshold is
exceeded and need to report an alarm status, and enable off means
that the threshold is exceeded without requiring an alarm.
Set/query collection period: the period for the device to collect sensor
information (range: 0-65535 seconds, when the value is 0, it means
real-time collection).
Set/query initialization calibration: calibrate the current detection
value (range: 400~2000, unit 0.01mA). After the device receives the
information, it starts calibration and feeds back the current calibration
value.
Query device status: query the current status of the device, including
the current collected value and alarm enable information.
Query version number: You can query the software version number of
the current sensor.
9. Common faults and handling
Ensure ZETA signal coverage
Ensure that the device is powered on, and the ZETA network device
management platform can observe that the ZETA module is online
Check the battery usage of the device. When the battery is low, replace
the battery in time.
