WORKING PRINCIPLES SEVEN Sensor Box is an UV protected aluminum box, including an electronic card where 6 different sensors can be connected and has an RS485 port output to transfer data in Modbus RTU protocol to the datalogger or Scada system. SEVEN provides Sunspec options for needed devices, also. CONSTRUCTION FEATURES Sensor Box: The solar cell, all the input connectors and the output connector and ventilation port located on an UV protected aluminum box, is called Sensor Box. The sensor box has two opening access for and the mounting holes on its sides are for easy site installation. There are three option for IP Class; IP68, IP65 and IP54. For ventilation purpose there are 1mm holes at bottom side of the box or a ventilation plug on its side. Connectors: The Sensor Box has max. 6 inputs and 1 output connectors. Each plastic connector has a different pin number which prevents any connection confusion during site installation. The connection cables are delivered as 1.5m or 3m lengths. SEVEN Sensor Box is designed as Plug & Run device and end user friendly operation. Ventilation Port: This port is made of a plastic material and allows air circulation and moisture releasing in the box which is required for long run life time of the electronic card. The same function can be provided through the 1 mm holes drilled in the bottom of the box, when ventilation plug is not used. Configuration Tool: SEVEN firmware is downloadable directly from SEVEN website https://www.sevensensor.com/software Download the program and run it. The Modbus parameter can be set and the connected sensors data can be monitored via this configuration tool. DATALOGGER COMMUNICATION SEVEN Sensor Boxes communicate by Modbus RTU protocol through RS485. SEVEN sensor is compatible with many well-known datalogger brands. However, the purchaser should get the confirmation from SEVEN whether his datalogger is compatible with SEVEN sensor or not. Seven Sensor Solutions (3S) • [email protected] • www.seven

WARRANTY SEVEN provides 5-year warranty certificate against manufacturer defects for each sensor box. The certificate will be delivered with products. This certificate does not cover loss or damages due to incorrect usage of the sensor box. SEVEN Sensor Box should not be opened, the fact that will cause the termination of the warranty conditions.
