Description of Unit 23/88
The regular adjustment takes place at regular intervals, e.g. 15 minutes.
The interval is defined by parameter setting.
Adjustment interval e.g. 15 min
> 2 s
< 100 ms bounce-free
Since the synchronisation signal is transmitted at regular intervals (e.g.
00:00h, 00:15h, 00:30h etc) it carries a time information. When, for
instance, the meter receives the third synchronisation signal of the day
(00:30h) the calendar clock is adjusted to 00:30h. The reaction of the
meter to the synchronisation signal depends on the detected deviation.
The meter will accept the synchronisation pulse any time but only once
within synchronisation interval.
Note
Ignoring second synchronisation pulse
A second synchronisation pulse within the adjustment interval will be
ignored.
With the daily adjustment, the meter allows one time window per day
within which the synchronisation pulse must be sent to the meter. The time
of the day (e.g. 22:00h) and the width (e.g. one minute) of the window
can be defined by parameter setting.

If the “time of the day” parameter is set to 22:00h and the meter receives
a synchronisation signal within the defined window, the meter is adjusted
to 22:00h. The reaction of the meter to the synchronisation signal depends
on the deviation.
The meter will not accept a synchronisation pulse outside the time window
and the signal will therefore have no effect.
