Watchdog
You can check how many times the unit has been switched on, and look at the date
and time of the last ten starts. This can be useful if there have been power failures
or if for any reason the Sludge Finder 2 restarts due to a fault condition. The
Sludge Finder 2 can be backed up from a battery which automatically cuts in
during power failure. Battery backed up units will continue uninterrupted
operation and therefore will not register a loss of mains power. If, however, the
battery were to fail during a mains power interruption, a start up would be recorded
once power has been restored.
P940 Number of Starts
This parameter shows how many times the unit has been powered up.
P941-P960 Start Date & Time
Parameters P941 and P942 show the date and time that the unit was last started.
There are ten start dates & times recorded, which are parameters P943-P960.
The first on the list are the most recent, and the last ones are the oldest. These are
read only, and cannot be changed.
