The time and date indicate when the fault was written to the log. It is important
that the real-time clock be set properly to have an accurate idea of when the faults
occurred.
The PI shows the floor label of the closest doors zone magnet and the position
shows feet and inches.
FPM indicates how fast the car was moving.
Four additional indicators on the bottom row show CPU, ETS position, and Extra
Bytes 1 and 2.
Extra Byte Definitions
Computer that Detected the Fault or Alarm

State of ETS Switches when Fault or Alarm Occurred
DET switch was open, UET switch was closed.
Both DET and UET switches were closed.
DET switch was closed, UET switch was open.
Either DET or UET were both open and the CPU recording the fault
did not have accurate information about the state of the switches.
Faults that occur shortly after a power on or during a system
communication loss may indicate an unknown ETS position.
Extra Byte 1 and Extra Byte 2 are normally both zero indicating that no additional
information is available. Several faults and alarms will store additional information
in these bytes that can be used to diagnose the cause of the fault.
