Schneider Electric XBTA8 Compact Terminal UNI-TE Protocol User Guide

Schneider Electric XBTA8 Compact Terminal UNI-TE Protocol allows users to communicate with a range of devices using the UNI-TE protocol. It features self-diagnostic functions to ensure optimal performance. Automatic self-tests are carried out at power-up and during the test procedure of the CONFIGURATION mode. These checks include PROM CHECK, RAM CHECK, KEYBOARD FAULT, REGISTER FAULT, EEPROM FAULT, and RUNNING. If any permanent faults are detected, the supply voltage must be switched off. The device also provides error messages to assist with troubleshooting.

automatically.
These tests are also carried out during the test procedure of the CONFIGURATION
mode. Thesechecks are intended to reassurethe userthattheterminal is operating
under the best conditions.
In order to quit a permanent fault, the supply voitage must be switched off.
