ST800 Guidance Notes

Fault Log

The ST800 uses the same fault log commands as on the T400. Therefore to display

the currently active fault flags, enter ‘FFS↵’ (fast fault scan), and for the fault data,

enter ‘FDS↵’ (fast data scan). The ‘+’ and ‘-’ keys can then be used to scroll through

the active faults.

For backwards compatibility, the ‘FLF’ (fault log flags) and ‘FLD’ (fault log data)

handset commands still exist.

The ST800 also contains a timestamped historic rolling log which can be viewed

using the command ‘LOG↵’. When ‘LOG↵’ is first entered, the most recent entry is

displayed. To move through the historic log, use the ‘+’ and ‘-’ keys as normal.

A timestamped entry is added to the log when:-

• the controller is initialised, i.e. on first time power-up or after a config. change,

• the power is switched off and back on, and whether a self test was performed,

• when any FLF/FLD fault is set or is cleared,

• when the lamp monitor is reset,

• when any lamp fails or is replaced,

• when any detector input fails DFM, when it next changes state, and when the

fault is eventually cleared,

Note that this rolling log is not cleared when the configuration PROM is changed.

The controller remembers your last position in the log, so if you type ‘LOG’ again

after another command is used, it will return you to your last position in the log.

To return to the end of the log, press <SPACE>. If the ‘+’ key is then used, then the

most recent entries are displayed as before, but if the ‘-’ key is used, then the log

can be viewed in the reverse direction, starting with the oldest entry still present in

the rolling log.

However, if the power is switched off and back on, or the handset is disconnected,

then the first time that ‘LOG↵’ is entered, the most recent entry is always displayed.

The table on the following pages summarizes the ST800 fault log.

The ‘FLF’ column identifies the fault log flag number and the ‘FLD’ column identifies

the associated fault log data byte(s).

The ‘ABBR’ column shows the abbreviation that appears along side the fault report

in the commands ‘FFS’ and ‘LOG’.
