Setting Function
B2-06=0
(Ignore)
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)
This detection checks the wave shape, if it is not sinusoidal
within certain limits, the AC input voltage is rejected.
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.
This will result in a slightly longer transfer time.
B2-07: Ground Relay
Used to enable/disable the internal ground relay functionality. The ground relay is useful
when an earth-leakage circuit-breaker is part of the installation.
When ATS (Auto Transfer Switch) is open (INVERTER mode), the Neutral of the inverter
is connected to “G” terminal.
When ATS closes (AC IN is transferred to AC OUT), the Neutral is first disconnected from
“G” terminal.
Setting Function
B2-07=0 The internal ground relay is open with “G” terminal.
B2-07=1
(Initial setting)
The internal ground relay is closed with “G” terminal.
B2-08: AC IN Frequency Range
Refer to page 64 (B1-01)
B2-09: AC IN Dynamic Current Limit
This setting is an expansion of the AC IN Current Limit (B2-05) mechanism.
Setting Function
B2-09=0
(Initial setting)
The AC current limit is specified by the AC IN Current
Limit (B2-05) setting
