B2 Group (Auto Transfer Switch)
B2-01: AC IN Low Disconnect
Main Menu>Programming>ENT>General>ENT>Auto transfer Switch>ENT
z
Use constant B2-01 to determine the AC IN voltage below which level the ATS (Auto Transfer
Switch) will switch off.
z
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
Main Menu>Programming>ENT>General>ENT>Auto transfer Switch>ENT
z
This setting forms a pair with AC IN Low Disconnect (B2-01). With this setting, one
determines 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. The parameter which is changed is the difference
between AC IN Low Disconnect (B2-01) and AC IN Low Connect (B2-02).
z
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)
z
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.
z
B2-02=B2-01+offset voltage
For example: CP-1500-122, when B2-01=180V, B2-02=187V, offset voltage=7V (187-180),
B2-02 will automatically go to 197V(190+7) after B2-01 is changed to 190V.
B2-03: AC IN High Connect
Main Menu>Programming>ENT>General>ENT>Auto transfer Switch>ENT
z
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.
z
In fact, the parameter which is changed is the difference between AC IN High Disconnect
(B2-04) and AC IN High Connect (B2-03).
z
The result of this is that when changing B2-04 level, this level (B2-03) also changes.
z
B2-03=B2-04
–
offset voltage For example: CP-1500-122, when B2-03=265V, B2-04=270V,
offset voltage=5V (270-265), B2-03 will automatically go to 255V(260
–
5) after B2-04 is
changed to 260V.
