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. This is due to the same parameter being
also used for TEST activated by an SMS command.
In some applications, it is useful to inhibit the automatic intervention of the engine for auxiliary
source failure in hours or days where the auxiliary source is not used. For example, if a factory
is closed on Sunday, the engine should never start in this day for auxiliary source 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.
The parameters related to this function are the following:
•
P.0421: allows to specify in which days of week the engine can start automatically. It
is a bit-configurable parameter; each bit of the parameter corresponds to a day of the
week. The value to be set for the parameter is the sum of the value fields in the
following table related to the days needed.

P.0422: allows to configure the start of the time interval during which the engine can
start automatically (in hours and minutes).
•
P.0423: allows to configure the end of the time interval during which the engine can
start automatically (in hours and minutes).
Usually P.0422 will be set to a value lower than P.0423. On the contrary, if it contains a higher
value, the controller infers that the time interval is set across midnight: in this case, the time
set with P.0422 refers to the days selected with P.0421, while the time set with P.0423 refers
to the following days.
For example, in case an automatic gen-set start is required only Monday through Friday,
between 08:00 and 18:00, you must set:
P.0421 = 62 (3E in hexadecimal format) (2+4+8+16+32)
P.0422 = 08:00
P.0423 = 18:00
In some applications, it is useful to force the automatic intervention of the engine in hours or
days where it is not used. With this function you can select in which days and in which time
intervals the gen-set is forced to start. The planning is made on a weekly basis: therefore, it is
possible to plan in which days the generator must start. Besides days, it is possible to set a
single auto operation forcing time slot common to all selected days.
The parameters related to this function are the following:
