Watchdog
P1 and P2
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 Ultra Twin restarts due to a fault
condition. The Ultra Twin 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.
The following parameters can be accessed by directly entering the parameter
number. To do this, enter the program mode and then type in the
appropriate parameter number.
P*940 Number of Starts
This parameter shows how many times the unit has been powered up.
P*941-P*960 Start Date & Time
Parameters P*941 and P*942 show the date and time that the unit was last
started. There are ten start dates & times recorded, which are parameters
P*943-P*960. The first on the list are the most recent, and the last ones are
the oldest. These are read only, and cannot be changed.
