The unit has a Vigilance Device which sounds every 60 Seconds and has to be reset. Also make sure you cancel the AWS within 3 seconds
Are you exceeding the speed shown on the TVM display - that will cause an Emergency Brake Application. On the High Speed Section you have to run to the Cab Display - not the Track Speed.
