The EPV does not open and the emergency brake does not activate in the event of a fault
that restricts subsequent use of the system. No fault is indicated on the front panel of the
central unit or on the signal repeater. In this case, the fault involves the signal repeater in the
inactive cab. These faults only restrict the operation of the train protection system to the cab
in which the signal repeater that is operating normally is installed.
All faults detected during operations in ZAV working regime while in motion are classified as
faults restricting subsequent use of the system. These faults are then reclassified depending
