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 3 restarts due to a fault
condition. The Ultra 3 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.
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.
Daylight Saving Time
Important Information
To ensure the correct operation of Daylight Saving Time P932 Time should
be checked, and adjusted if necessary, to ensure that it is set for the current
valid time.
P970 DST Enable
When Enabled (set to 1) the internal clock will be automatically adjusted to
compensate for the difference between standard time and Daylight Saving
Time. Default = 1 (On)
P971 DST Difference
This parameter sets the time difference between standard time and Daylight
Saving Time. The time difference is entered in HH:MM. Default = 01:00
