This function is used to determine the priority level of the battery charger within the network group.
The use of this function is needed where there are battery chargers in parallel inside a group.
If there are two battery chargers in parallel, set on one unit the “
Priority 1
” and set on the other the “
Priority 2
”; if
there are three battery chargers in parallel, set respectively the “
Priority 1
”, “
Priority 2
” and “
Priority 3
”.
A battery charger set with “Priority 1” must always be present inside the group.
In case only one battery charger is present in the group, then set it as “
Priority 1
”.
MONITOR MODE

This function allows to enable or disable the battery charger’s “Monitor” mode.
The “Monitor” mode, if activated, allows the battery charger to transmit and receive data on the CAN network, even
without the AC mains, obtaining power supply from the battery bank connected to the MASTER output. This allows the
battery charger to communicate with the terminals present on the CAN network and keep the control panel active
even without the AC mains.
The current absorption, in “Monitor” mode, is lower than 70 mA.
The battery charger in “monitor” mode switches off if the voltage of the master battery bank is lower than 7 Vdc for
models 12 Vds and lower than 14 Vdc for models 24 Vdc.
In case of battery chargers connected in parallel (current sharing mode), the selected option must be the same in all
battery chargers.

Exit
This function allows to set the value, in the form of a percentage, of the FLOAT threshold (see paragraph “OPERATION
- Charge features - FLOAT phase).
For example, for the model SBC 1200 NRG FR (maximum rated current100A) by setting the 20%, a corresponding
absolute value of the FLOAT threshold of 20A (20% of 100A) will be obtained.
By changing the FLOAT threshold, the batteries’ charge can be optimized according to their capacity. Moreover, this
function can be used to allow the correct shift into the FLOAT phase in case of constant absorption (caused by a load
connected to the battery bank). In case of battery chargers connected in parallel (current sharing mode), the selected
option must be the same in all battery chargers
The devices belonging to one group “
A
”, “
B
” o “
C
” can only dialog between themselves.
Group “
U
” (Universal) is an exception as this can dialog with any other device.
The distinction between different groups is very important in order to connect all the devices to the same CAN
network even if they belong to different electrical systems.
