Self-Test
The FS24XPlus™ executes a self-test sequence every minute. All optical sensor channels and the
related processing of sensor data are evaluated to ensure that analog circuits, processors, and
memory are functional. Depending on the function, tests are repeated several times to confirm
device status prior to declaring a fault. In the case of the optical self-test, which evaluates the optical
system by flashing an IR LED and monitoring the reflection from the window, a fault in not declared
until a total of 5 consecutive test attempts have failed. This takes a total of five minutes to complete.
Additional self-tests are conducted on a continuing basis to ensure the continuity of relay coils.
