7. Operation SEM mode selection (Super Eco Mode)
SEM MODE:
This parameter (values Y / N) enables or disables the operation in SEM mode (Intelligent Energy
Management).
If the value is Y and the current time is in the interval for the current day, the SEM mode is active.
The activation / deactivation of SEM mode is indicated each time in the event list.
In order to check the inverter function, at least 1 minute of VFI mode must be programmed during the
week (the Y / N parameter is automatically disabled if this condition is not satisfied).
In case this minimum time in VFI mode is not respected, the SEM mode will be disabled.
If the value is N, the UPS is normally operating in VFI / double conversion mode at all times.
d1 ÷ d7: Enabling time in function of weekdays.
For the weekdays from d1 to d7 (Saturday to Friday) the edit mode (edit day) allows to define time
intervals when the UPS is operating in SEM mode.
The hour is given in 24-hour format.
These intervals are defined by:
SEM START: the hour of the day after which the SEM mode is enabled.
The SEM mode is enabled until the following SEM STOP time is reached (the SEM STOP
time of the same day if this is later than the SEM START time, the SEM STOP time of
the following day otherwise).
SEM STOP: the hour of the day before which the SEM mode is enabled.
The SEM mode is enabled starting from the preceding SEM START time (the SEM START time of the same
day if this is earlier than the SEM STOP time, the SEM START time of the previous day otherwise).
Identical times for SEM START and SEM STOP maintain the existing mode only in case the previous
command was SEM START and the following command will be SEM STOP.
HOURS SELECTED:
The number of SEM mode hours per weekday (from d1 - Saturday to d7 - Friday) is displayed in the
operation mode parameter window (ceiling value).
To better understand the SEM programming modes, some typical examples are shown:
Example 1:
For continuous SEM mode set the SEM START times to 00:00 and the SEM STOP times to 23:59 for all
weekdays, but almost 1 day must have 1 minute of VFI programmation: i.e d2 - Sunday 00:00 to 23:58).
