• Under-Voltage Trip (PCVMRStatus_O)
• Input Protection Fault
• LFR Trip
• PB4/E-Stop
• M2 Contactor Open Status Failure
• Trip_CB2 (TripPrechargeCB2_O) is asserted
The SOP input control flags below are available for particular cell types using the pre-charge
function by selecting Type 4 pre-charge. No dedicated inputs are used.
