LX system structure
4.3.1 System
structure
A Typical layout of the SPA-5/LVA LX is presented at the Figure 4. Types and
number of devices at LX, as well as the presence and types of the interfaces are
individually defined for the specific system localization.
ERR-2 (SPA-5/LVA control and power supply unit) is connected via serial
transmission link with the Ebilock interlocking system. Separate transmission link
connects ERR-2 with Remote Control Device (ERP-7).
Ebilock sends orders (e.g. engagement and disengagement commands) to LX and
receives statuses and simplified diagnostic messages from LX.
