Description
INVERTER
Inverter
(Enabled/
Disabled)
When
Disable
is selected and AC is lost, the FXM will be in Standby mode. The
inverter cannot be started through the Inverter On/Off menu,
When
Enable
is selected and AC is lost, the FXM will be in Inverter mode. Turning
inverter on/off manually will work.
INVERTER
Inverter (On/
Off)
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.
LVD DSCNNCT
Battery voltage value at which the LVD configured relay should open
LVD CONNECT
Battery voltage value at which the LVD configured relay should close
BYPASS
Inverter Bypass
This function can only be switched on when the Alpha FXM is in Line mode. When
switched on, it locks the Alpha FXM into the Line mode, switches off the battery
charger and makes the output voltage equal to the input voltage.
Used when:
•
Replacing the batteries.
OR:
•
To allow the use of a break-before-make manual bypass switch so the
Alpha FXM can be shut off for maintenance or replacement without interrupting
power to the load.
BATT TEST
Battery Test
Available when
CHARGER
on the Control Menu is set to
Standard
method.
Starts the battery test, which uses depth-of-discharge setting, the battery capacity,
Peukert number, and open-circuit voltage. This setting can be adjusted using
BT TS
DOD
menu. A battery test is also performed during the self test.
BT TS DOD
Battery Test
Depth-of-
Discharge
Available when
CHARGER
on the Control Menu is set to
Standard
method.
Sets 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.
AUTO TEST
Automatic Test
Available when
CHARGER
on the Control Menu is set to
Standard
method.
If the GUI periodic self test is enabled, this starts the test when it is scheduled to
take place.
SHUTDOWN
Shutdown AC
and DC (On/
Off)
When this function is switched
On
, the Alpha FXM inverter is shut off. Neither Line
nor Inverter power is supplied to the load. If a dry contact was used as a LVD, the
LVD will open.
SHUTDOWN AC
Shutdown AC
(On/Off)
When this function is switched
On
, the Alpha FXM inverter is shut off. Neither Line
nor Inverter power is supplied to the load.
SHUTDOWN DC
Shutdown DC
(On/Off)
When this function is switched
On
, the LVD configured relay will be de-energized.
Applies when ANY programmable dry contact is programmed to be the Low Voltage
Disconnect indicator. See "UPS Maintenance > Relay & Load Shed" on page 41.
When the function is switched from
On
to
Off,
a 10 second delay occurs before the
LVD configured relay is re-energized.
