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 5
restarts due to a fault
condition. The
Ultra 5
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 was 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
.
