Installation instructions
- Install steel rail
Before installation, clean the burrs on the mounting surface of the rail and the dirt on the wall. Attach the guide rail to the mounting surface and confirm the bolt hole position, and tighten the bolts one by one.
- Install sensor device
Snap the sensor onto the rail and push the lower snap to engage the rail as shown:
- Wiring
Connect according to the label on the sensor label, as shown in the figure:
- NC : Reserved, no wiring required
- L/N: Connected to the mains, AC 100~240V
- A+ : 485 Positive
- B- : 485 Negative
Use of Device
- Indicator Description
- Red: power indicator Lights up when power is normal
- Yellow: module status indicator.
- Registration: Lights up 2ms every 2s until the registration is successful. When the device goes to sleep, the light is off.
- Successfully registered: Lights up 2ms every 500ms, and lasts for 5s.
- Working normally: Lights up 2ms every 1 minute
- Green: sensor operation indicator
- Lights up 1 second for every time the data is collected.
- Alarm occurred: 500ms on, 500ms off, until the alarm is cleared.
- Steps for use
- Connect the antenna and place the device within the ZETA network coverage area ;
- Power on, wait for the device to connect to the network
- Configure alarm thresholds and reporting periods based on requirements.
- Daily maintenance and data viewing
- Support function
- Version number: Report the software version number of the sensor only once after power-on.
- Status report: Report status data periodically according to the setting.
- Set/Query the parameter reporting period: can set or query the data reporting cycle (Range: 1~65535 min, default: 12*60min)
- Set/Query address code: 485 communication requires address code matching. (Range: 1~247, default: none)
- Set/Query register function code: Query or set the function code of Modbus (range: 03 or 04)
- Set/Query acquisition parameters: When setting, you need to input the registered address to be read and the number of bytes read. You can set multiple acquisition parameters at the one time.
- Set/Query serial port parameters: The serial port parameters include: baud rate, data bit, parity bit, stop bit, and the parameters need to be matched with the device to read the data normally.
- Query data: In addition to waiting for the sensor to report, you can actively query the current data collected by the device.
- Query version number: You can query the software version number of the current sensor.
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.
