II. MAINTENANCE 2.1 Maintenance There is no requirement for maintenance of the Hardware of the iConnnector 2.2 Troubleshooting No. Phenomena Reason Solutions 1 Cannot read modbus No power supply, the power cord is incorrectly connected Modbus connection pin A, B is loose or wrong Configuration slave address, baudrate, parity is not correct Reading the wrong command, wrong address register Check the power connection Check the connection modbus A, B Check the configuration of slave address, baudrate, parity iConnector only supports modbus 3, 4, and 16. Check if the value of modbus status returned by 2 or 3 is an incorrect address reading. 2 Failed to add auto sensor (iConnector integrated Co-ordinator version) When the first 5 minutes are up, the sensor cannot be added Node needs to be added further away from WS433-CL The iConnector and the node are configured to run at 2 different RF frequencies, or different data rates Unplug, wait 10 seconds, plug in again to enable automatic add or write to modbus Enb_auto_add_sensors = 1 Bringing nodes and iConnector together or temporarily setting the smaller Rssi_threshold can add sensors farther (then return the old values) Check the RF frequency, data rate of iConnector and the node 3 Read modbus normal health values but read the data of the node, all are 0 The modbus 4 command only supports FW 1.9, old FWs can't read command 4 Check the FW of WS433-CL in iConnector if it is older than 1.9 then use command 3 to read data and other registers 4 The node's data has no data of prm1 and prm2 The sensor attached to the node is loose For the WS433-M12F node, if the sensor is attached after the battery is attached to the node, the sensor type may be different so the data cannot be read. Attach the sensor to the node firmly Attach the sensor to the WS433-M12F node first. Then remove the node pin, wait for 10 seconds, re-attach to the node to re-identify the sensor 5 Status led of iConnector doesn’t light No power supply Check if the power cable is disconnected Check if the connector of iConnector is loose or disconnected 6 Mobus led of iConnector doesn’t light No RS485 connection Check if the signal cable is loose or disconnected 7 Network led of iConnector doesn’t light No network connection Check if the power cable is disconnected Check if the connector of iConnector is loose or disconnected
