B2 Group (Auto Transfer Switch)
B2-01: AC IN Low Disconnect
Use constant B2-01 to determine the AC IN voltage below which level the ATS (Auto
•
Transfer Switch) will switch off.
This voltage level will always lie below the
•
AC IN Low Connect (B2-02) level. In fact,
changing this level will also change the AC IN Low Connect (B2-02) level.
B2-02: AC IN Low Connect
This setting forms a pair with
•
AC IN Low Disconnect (B2-01). With this setting, one deter-
mines the AC IN low voltage at which level the ATS will switch on. This should lie above
AC IN Low Disconnect (B2-01) level to prevent continuous switching off the ATS when
the voltage is fluctuating around the level.
In fact, the parameter which is changed is the difference between
•
AC IN Low Disconnect
(B2-01) and AC IN Low Connect (B2-02).
The result of this is that when changing B2-01 level, this level (B2-02) also changes.
•
Note: B2-02 can be ignored for a short time when AC IN Waveform Check (B2-06) is
*
disabled (B2-06=0)
When the AC IN voltage drops due to the increasing charge current, the AC CHARGER
•
will take care that the voltage does not drop below this level.
B2-02=B2-01+offset voltage
•
B2-03: AC IN High Connect
This setting forms a pair with
•
AC IN High Disconnect (B2-04). With this setting, one
determines the AC IN high voltage at which level the ATS will switch on. This should lie
below the AC IN High Disconnect (B2-04) level to prevent continuous switching of the
ATS when the voltage is fluctuating around that level.
In fact, the parameter which is changed is the difference between
•
AC IN High Discon-
nect (B2-04) and AC IN High Connect (B2-03).
The result of this is that when changing B2-04 level, this level (B2-03) also changes.
•
B2-03=B2-04–offset voltage
•
B2-04: AC IN High Disconnect
Use constant B2-04 to determine the AC IN voltage above which level the ATS will switch
•
off.
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: AC IN Current Limit
Use constant B2-05 to set the specific maximum AC input current. This value is very
•
important for both battery charger and inverter output load support.
When using constant B2-05, the values determine the actual AC current limit.
