If more than one rectifier is installed in the system and the load is significantly less that the full rated capacity of
the installed rectifiers (e.g. load is on stand-by) the Smart Energy function can be activated in order to limit the
power consumption and increase the system efficiency. The Smart Energy function turns off unused rectifiers,
depending on the load activity. If a rectifier is in standby, an orange LED on its front panel will be illuminated.
It is recommended that this mode of operation should only be deployed when batteries are connected to the
system.
To activate this function, it is necessary to change the Boolean condition in the same menu (Edit Mode – DC
system – Configuration as shown in Figure 32). To avoid an unplanned activation of this function, it is
recommend that a PLC should be applied relating to the battery LVD (e.g. “@(alarm17)==false”). For more
details, please see the Comp@s user manual.

NOTE:
It is important to note there is a delay of 10 seconds on the rectifier remote shut-down function.
This hysteresis time is necessary in the event that the load fluctuates around a critical value.
CAUTION!
Please note that changes in configuration settings are only possible if the system is fitted with a
Comp@s Communication Card is present in the MCU.
