EV.8.1.1 The Shutdown Circuit consists of the following components, connected in series:
a. Accumulator Management System (AMS) EV.8.3
b. Insulation Monitoring Device (IMD) EV.8.6
c. Brake System Plausibility Device (BSPD) EV.8.7
e. Interlocks (as required) EV.8.9
f. Master Switches (GLVMS, TSMS) EV.8.10
h. Brake Over Travel Switch (BOTS) T.3.2
EV.8.1.2 The Shutdown Circuit must directly carry the current driving the Accumulator Isolation Relays (AIRs) and the Precharge Circuit Relay.
EV.8.1.3 The AMS, IMD, and BSPD parts of the Shutdown Circuit must be designed as Normally Open contacts
EV.8.1.4 The AMS, IMD and BSPD must have completely independent circuits to Open the Shutdown Circuit.
The respective circuits must be designed such that a failure cannot result in electrical power being fed back into the Shutdown Circuit.
EV.8.1.5 The Shutdown Buttons, BOTS, TSMS, GLVMS and Interlocks must directly carry the Shutdown Circuit current
