8.4.4 Historic Rolling Log

The Heimdall detector contains a ‘rolling’ historic log that records the elapsed time when

various events occurred. This elapsed time is defined as the period of time after the

detector was initially installed and is presented as:

Years: Days: Hours

To display the log entries, the terminal command ‘FLG’ is used. See the ‘FLG’

command for further details on operation (reference section 7.7).

A time stamped entry is added to the log when:

 the power is switched off and back on,

 when any fault is set, e.g. ‘FFS 11 DFMT:255’

 when any fault is cleared (RFL=1)

Note: The historic log is not cleared when a new detector configuration is loaded.

To view the historic rolling log, enter the command ‘FLG’, and the most recent entry is

displayed. Use the ‘+’ and ‘-’ keys to scroll (move) through the historic log.

If the ‘+’ key is then used then a more recent entry is displayed. If the ‘-’ key is used,

then the user may scroll through the log in the reverse direction.

To move directly to the most recent entry press <SPACE>.

If the power is cycled (switched off and back on), or the handset is disconnected, then

the next time that ‘FLG’ is entered, the most recent entry will be displayed.

The table below details the description of each possible fault flag and historic log entry.
