B3 Group (Parallel System)
B3-01: Number of Slaves
Main Menu>Programming>ENT>General>ENT>Parallel System>ENT
z
A parallel system is built with 1 master and up to 4 slaves with this setting, one can specify the
number of slaves in system. This setting has only to be done in the master. It is not required to
specify the number of slaves. The system will work just fine without this setting being
specified.
z
This setting is added for convenience of the end-user when the AC IN power is larger than the
total of B2-05* the number of the CombiPlus® ( Slaves) when B3-01=0. The only
effect of this setting is on the scaling of AC IN Current Limit (B2-05). If B3-01=0, one must
divide the available AC current by the number of CombiPlus® ( Slaves) and set the
limit accordingly. So an example of setting the B2-05=10A in a parallel system with 3
CombiPlus® would result in a limit of 3*10A=30A
z
Please Note: If however in this system the number of slaves is set 2 (B3-01=2), then the
division is done internally and setting the AC IN Current Limit to 10A (B2-05=10) will result in
10A for the whole system and shared by the Master and Slaves. This system is often applied
when the AC IN power is limited such as the generator of limited small capacity.
B4 Group (2-3 Phase)
B4-01: 2-3 Phase Connection
Main Menu>Programming>ENT>General>ENT>2-3 Phase>ENT
z
All the CombiPlus® in a multi-phase system must have 2-3 phase enabled. Use this setting to
perform this.
z
If more CombiPlus® per phase are connected in parallel, then only the masters of parallel
system must have 2-3 phase enabled.
Setting Function
B4-01=0
(Initial setting)
2-3 Phase connection disabled.
B4-01=1 2-3 Phase connection enabled.
