FAULT ISOLATION
1. General
This section gives all possible failure codes and their required action.
The Stratotimer ST3 has a built-in test (BIT) function, comprising a power-up built-in test (PBIT)
function, a continuous built-in test (CBIT) function and an initiated built-in test (IBIT) function.
If the status of either PBIT, CBIT or IBIT is Fail, the Stratotimer ST3 switches to failure mode and
a record of the failure is written to the BIT history file.
2. Failure Codes
A list of all possible failure codes and their required actions are shown in Table 101.
Failure codes are displayed in the top RH corner of the Stratotimer ST3 display.
