The Fabius Tiro backup battery comprises two series-connected 12 V
rechargeable batteries. While the machine is operating from AC, the total bat-
tery voltage at full charge should be within the range of 27.0 to 29.6 V. Battery
voltage can be measured at J5 on the main controller PCB assembly. During
battery operation, the low battery cutoff voltage should be within the range of
21.0 to 20.0 V.
Table 3 lists common failure modes and symptoms (excluding simultaneous
multiple faults) for the monitoring and display devices in the Fabius Tiro. Each
failure mode or symptom is keyed to a troubleshooting guide flow chart at the
back of this section to assist the service representative in locating the cause
of a problem. These flow charts assume that the machine is plugged into an
AC outlet with the correct voltage, and the machine is not running on its
backup battery.
