Description
INVERTER
Inverter
When inverter mode is set to ON, the Alpha FXM provides backup battery
power to the load. This mode of operation is normally activated automatically
when line power becomes unavailable, or the line power is not qualified. You
can also put the Alpha FXM into this mode during initial startup in the
absence of line power or because of unqualified line power. See #31Inverter
On/Off in Table I.
DC CONNECT
DC Output
Connect
Voltage
One of the dry contacts of the FXM350 can be programmed to operate as a
control for external DC disconnect and reconnect. (See LVD setting under
"7.5.4
Programming the Dry Contacts" on page 82). The dry contact is energized
when the battery voltage is greater than the DC Connect set voltage and will
de-energize if the battery voltage drops below 42V for 48V system (21V for
24V system). The default reconnect voltage is set to 48VDC and can be
adjusted up to 51VDC.
BYPASS
Inverter
Bypass
This function can be enabled only when the Alpha FXM is in Line mode.
When enabled, the FXM locks into Line mode (no AVR) and disables the
battery charger.
This mode is used when maintaining batteries.
OR
Allows the use of a break-before-make manual bypass switch so the Alpha
FXM can be shut off for maintenance without interrupting power to the load.
BATT TEST
Battery Test
Starts the battery test that uses depth-of-discharge setting that can be
adjusted using BT TS DOD menu.
BT TS DOD
Lets you set the desired battery test depth-of-discharge to a value between
0 and 100%. Make sure that the set time duration is shorter than the max
back up time of your battery bank. Otherwise, you will drain the battery and
trigger a fault
–
Batt Volt Low
. The default value is set to 20% DoD.
