Sices DST4600A - Real Time Clock Option; Displaying Time and Date of RTC

40 User’s Manual
The “OUTPUT 1” output can be connected to a circuit breaker for automatically disconnect the
less important loads. If it is connected to a changeover circuit, the board automatically re-
connect the less important loads when the active power back into its nominal range.
Comparing the maximum power signal function to the low power signal function, there are the
following differences:
 Parameter P60 is not used (and so the function is always enabled).
 The genset breaker status is not used (and so is not necessary to connect it).
 The “F49” warning is activated
 The “OUTPUT 1” output is controlled in the opposite way than in low load function: it
is activated if power is greater than P58, while in the low power function it is activated
if the power is lower then P56.
Starting from SW revision 08.00.24, it is possible to install in DST4600A boards a Real Time
Clock option (RTC). The option is equipped by a lithium battery that let the watch running also
without supply. The expected duration of the battery is quite 10 years.
RTC has a full time/date management set of function (hours, minutes, seconds, day, month,
year and day of the week).
RTC let the board implements the following function:
 Permanent storing of events alongside date and time.
 Automatic periodical test of generator set at preset time and days of the week.
 Time Lock of Generator set operation at preset time and days of the week.
If the option is installed and in OFF/RESET mode, pressing STOP pushbutton the RTC display
mode is entered.
The displays will show hours:
 Display “F”: hours (00-23)
 Display “V”: minutes (00-59)
 Display “A”: seconds (00-59)
Pressing “F1” or “F2” the mode will change to date:
 Display “F”: day (01-31)
 Display “V”: month (01-12)
 Display “A”: year (00-99)
This mode is outlined by the light on of the dot at the least significant digit of the displays.
Pressing again “F1” and “F2” the mode will revert to hour.
Pressing STOP again the RTC display mode is exit.
From SW release 08.00.35, the displays are blinking if the RTC date/time is not reliable (and
so is required that the operator set the correct date/time).
