B2-04: AC IN High Disconnect
Main Menu>Programming>ENT>General>ENT>Auto transfer Switch>ENT
z
Use constant B2-04 to determine the AC IN voltage above which level the ATS will switch off.
z
This voltage level will always lie above the AC IN High Connect (B2-03) level. In fact,
changing this level will also change the AC IN High Connect (B2-03) level.
B2-05: Interactive Power Sharing “AC IN Current Limit”
Main Menu>Programming>ENT>General>ENT>Auto transfer Switch>ENT
z
Use constant B2-05 to set the set the specific maximum AC input current. This value is very
important for both battery charger and inverter output power Support.
z
When using constant B2-05, the values determine the actual AC current limit.
※
Note: With Power Support enabled, there is a minimum value for the AC input current limit.
Please see the note at Power Support (page 71).
B2-06: AC IN Waveform Check
Main Menu>Programming>ENT>General>ENT>Auto transfer Switch>ENT
z
Use constant B2-06 to enable/disable the fast detection of input voltage wave shape.
Setting Function
B2-06=0
(Ignore)
z
By disabling AC IN waveform check, AC IN Low
Disconnect (B2-01) is ignored. When the load current is
higher 1.5 times than AC In Current Limit (B2-05), this is
used to prevent unnecessary switching to INVERTER due
to voltage drop when a high load is connected.
B2-06=1
(Initial setting)
(Active)
z
This detection checks the wave shape, if it is not sinusoidal
within certain limits, the AC input voltage is rejected.
z
However, certain generator or very weak mains supply
have an ill shaped sinusoidal output especially when the
load suddenly changes. The fast detection will detect a
failure in such a case.
z
This will result in a slightly longer transfer time.
