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
When the function is switched from
On
to
Off
,
a 10 second delay occurs
before the
LVD configured relay is re-energized.
SENSE TYPE
Sense Type
This function can only be used when the Alpha FXM is in Standby or
Shutdown mode (Table A).
Normal:
The Alpha FXM can operate successfully with most line
conditions.
OR:
Generator:
This setting increases noise tolerance so the fluctuations
created by a generator are acceptable. (A noisy line can cause the Alpha
FXM to constantly switch between inverter and line modes.)
FUNC MODE
Functional
Mode
The Functional mode can be changed when the Alpha FXM is in any mode
(Table C and "Table V — Boost/Buck/Line Transfer Thresholds" on page
82).
Automatic Voltage Regulation (AVR):
Buck and boost modes are active.
OR:
Quality:
Buck and boost modes are switched off; the input voltage is the
Alpha FXM output voltage.
VOLTAGE
Voltage
Sets the Alpha FXM output voltage setting to one of the voltages specified
in "Specifications" on page 80. Changing the voltage setting from factory
default should be done by a qualified technician acting under the
instructions of AOE Technical Support (+49/9122-79-889-0). Failure to
contact Alpha and Outback Energy before performing this procedure could
void your warranty.
AUTO FREQ
Automatic
Frequency
Detection
Enable
(default) allows the unit to detect and automatically configure the
AC input frequency (50Hz or 60Hz).
In cases where the AC input frequency can be out of range for long
periods,
Disable
prevents the unit from switching back and forth between 50Hz and
60Hz.
FREQUENCY
Frequency
The frequency can only be changed when the Alpha FXM is in Standby
mode—to 50 Hz or 60 Hz. This change should ONLY be done by a
qualified technician acting under the instructions of AOE Technical
Support (+49 9122 79 889 0). Failure to contact Alpha and Outback
Energy before doing this procedure could void your warranty.
QUAL TIME
Line qualify
time
Set how long it takes for the Alpha FXM to return to Line mode after the
line has become requalified to make sure the line is stable. The factory
default setting is 3 seconds. User adjustable in increments of 1 sec until 1
minute, and then in increments of 1 minute to 15 minutes max.
