To reboot the rail field switch, push the reset button for at least 5 seconds.
Spurs Start-Up Management
Sequential Start-Up of Spurs
During start-up, the spurs are sequentially activated to minimize the initial high inrush current
demand for the auxiliary power supply. Therefore, the auxiliary power supply is less stressed
during the start-up phase, and its expected useful lifetime is increased.
Fold-Back Characteristics of the Spur Short Circuit Current Limitation
If a spur short circuit occurs, the spur current is switched off quickly. When the short circuit cur-
rent has been cleared, the spur current returns. If multiple simultaneous short circuit currents
occur, the current management system minimizes the additional current demand of the auxil-
iary power supply.
Note
For more information refer to the software manual or read the diagnosis information provided by
the web server or the asset management tool.
