NEXSENS G2-Rain Alert System

IMPORTANT – BEFORE FIELD DEPLOYMENT: Completely configure new G2 systems with a web connection in a nearby work area. Operate the system for several hours and ensure correct sensor readings. Use this test run to become familiar with the features and functions.
Overview
- The G2-RAIN Alert System includes an integrated mo-dem. Power is provided internally through (2) D-Cell lithium batteries. An external power cable (optional ac-cessory) allows connection to an SP-Series solar panel for recharging the internal batteries and direct communica-tion (serial to PC). The integrated tipping bucket supplies accurate rainfall measurements (one tip per 0.01” rain).
- Data is accessed and stored on the WQData LIVE web datacenter. An easy-to-use dashboard and built-in sensor library automatically facilitate setup and configuration.
What’s Included?
(1) G2-RAIN-RTU
(1) G2 series battery pack (installed)
(1) Rain gauge
(1) SMA antenna
(1) 9/64” hex wrench
(1) Quick start guide
- To get started:
Go to WQDataLIVE.com- Create a new account or sign into an existing account.
- Choose or create the project that will contain the data logger by selecting the Projects link from the bottom right footer of the page.
- Open the project and go to the ADMIN tab located at the top of the project dashboard and click Settings.
- From there, choose the Project/Site pull down menu and select the site for the new data logger.
- If a site has not been created, select New Site.
- Enter the claim code listed below int o the space provided under Assigned Devices.
- Remove the siphoning tipping bucket by using the 9/64” hex wrench to loosen the (3) bolts connecting the bucket and RTU.
- Lift the bucket up gently.
- Remove the rubbing band from the tipping apparatus.
- Reinstall the bucket and tighten bolts.
Lift bucket to remove the rubber band on the tipping apparatus.
- Attach the antenna to the copper SMA connector found on the bottom of the G2-RTU.
Rotate the antenna clockwise onto the threads of the SMA connector. - Internal power- Use the included flathead screwdriver to turn the black power set screw clockwise on the bottom of the G2-RTU.
- Listen for the single audible beep to confirm power connection.
- After a few seconds:
- Two beeps = sufficient cellular signal
- Three beeps = insufficient cellular signal
- To power down, unscrew the set screw until the o-ring is visible.
Turn the black power set screw clockwise to apply battery using internal batteries.
- External power- Connect the G2-RTU adapter cable to an SP-Series solar panel or an AC power adapter.
- Listen for the single audible beep to confirm power connection.
- After a few seconds:
- Two beeps = sufficient cellular signal
- Three beeps = insufficient cellular signal
