Correct installation of the product is important for safety and performance. If you have not asked 4B to perform the installation of the unit on your behalf, it is critical for the safety of your operation and those who may perform work on your operation that you select a qualified and competent electrical installer to undertake the installation.
WARNING • Rotating machinery can cause serious injury or death • Always lockout and tagout the machine prior to installation PRODUCT OVERVIEW The T400N ELITE is a standalone monitoring and shutdown controller. The T400N operates by reading up- to 8 NTC temperature sensors and comparing their temperature to a pre-set limit. If that limit is exceeded the unit will activate an alarm, followed by operating a stop relay after a specified delay.

RS485 PROTOCOL The user can communicate with T400N over RS485 network by using simple PLC protocol. Every T400N slave on the RS485 network has 2 byte address (0 - 65535). This protocol is developed to ease interfacing of PLC systems with T400N Elite. In order to communicate with the slave (T400N), the master sends a 5 byte packet to the slave and the slave responds with the complete status of all the 8 sensors (sensor used/not used, sensor status, sensor temperature and alarm temperature) as part of a single packet which consists of 25 bytes.

WARNING • Rotating machinery can cause serious injury or death • Always lockout and tagout the machine prior to installation WARNING The control unit is susceptible to static voltage. Connection of a ground to terminal 31 is essential for optimum performance. Prior to this connection, static handling precautions should be taken. INSTALLATION INSTRUCTIONS All wiring must be In accordance with local and national electrical codes and should be undertaken by an experienced and qualified electrician.
10. The wiring installation must extend to within 1 mm of the metal face of the terminal. 11. All leads must be insulated for the appropriate voltage. 12. Not more than 1 single or multiple strand cable is to be connected to any terminal unless multiple conductors have previously been joined in a suitable manner (e.g.
