Esempio 1<br />
Requisito originario:<br />
REQ_BRAKE_61<br />
As above described when the train will depart, the following action will be provided (see document<br />
[2.11] for more details ):<br />
ATO release the Propulsion Cut Out (set High) and<br />
commands on MVB (dataset 707/708) Coasting and<br />
Propulsion Reset, the effort request is set to 0%.<br />
TCMS will command the Coasting (dataset 500)<br />
and set to 0 Service Brake bit. TCMS set high<br />
the braking Train Line<br />
(Cmd_Braking =1) -> service brake set OFF. BCU will send back the status of service and holding<br />
brake bits.<br />
ATO set traction bit =1 on MVB and Coasting and<br />
Propulsion Reset bit = 0 and set the effort request to<br />
50%.<br />
TCMS will replay the traction effort requested by<br />
ATO on MVB to BCU and TCU.<br />
If both TCU are active (no fault present), the TCMS<br />
will set high the stopping brake command (wired and<br />
low on MVB) at the same time when it requests traction<br />
effort. If one TCU is not able to provide effort, the<br />
TCMS will provide set high (wired and low on MVB)<br />
the stopping brake when the total train traction effort<br />
applied will reach the 10% of the maximum ( 14 kN).<br />
