The board is provided with a hardware clock. It is shown in detail in the page S.04. It can be
set through the programming menu 4.7.1
– Date/Time or the USB, and is used for many
functions:
History logs recordings.
Engine TEST start-up weekly planning.
Weekly planning of time intervals in which the gen-set can start automatically.
11.7.1
Engine TEST start-up weekly planning.
The engine TEST start-up is planned on a weekly basis. Thus it is possible to select in which
days the engine must be started for TEST.
ATTENTION!
Periodical test start-up is not linked to manual or auto
engine starts.
.
I.e. the engine may have been used just few minutes before but test will anyway start at due
time. In addition to the dates, it is also possible to select a start time and duration. This time
interval is common to all the days selected.
The parameters related to this function are the following:
P.0418: allows to specify in which days of week the engine TEST will be performed.
It is a bit-configurable parameter; each bit of the parameter corresponds to a day of
the week. The value you must set for the parameter is the sum of the value field of the
following table for the days needed.

Saturday
For example, if you want to perform the TEST only on Monday and Thursday, you
must set 18 (16+2).
P.0419: allows to set start time for the TEST (Hours and minutes).
P.0420: allows to configure the TEST duration (in minutes).
P.0420 sets the duration instead of an end test time.
11.7.2
Weekly scheduling of engine operating time intervals.
In some applications, it is useful to inhibit the automatic intervention of the engine for mains
failure in hours or days where the mains is not used. For example, if a factory is closed on
Sunday, the engine should never start in this day for mains fault (because it consumes
unnecessary fuel). With this function you can select in which days and in which time intervals
the gen-set can start automatically. The planning is made on a weekly basis: therefore, it is
possible to plan in which days the generator must operate. Besides days, it is possible to set
a single auto operation enable time slot common to all selected days.
