Meaning
Description
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 Alpha
Technical Support (1 888 462 7487). Failure to contact Alpha Technologies 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 Alpha Technical Support (1 888 462 7487). Failure to
contact Alpha Technologies 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.
INV CUTOFF
Inverter Cutoff
(Enabled/
Disabled)
When
Disable
is selected the default FXM inverter cutoff threshold is used.
When
Enable
is selected the user configured inverter cutoff threshold voltage is
used.
INV CUTOFF
Inverter Cutoff
Threshold
(Voltage)
Defines the point where the unit will switch from Inverter to Standby when the
battery is considered to be low or in order to preserve the battery. See "UPS
Maintenance > Inverter" on page 40.
CHARGER
Battery
charging
options
When
Standard
charger is selected, set
BATT FLOAT
to
AUTO
or
Constant
.
When
Bulk
charger is selected, set MAX VOLT and FLOAT VOLT. See section 6.2.2
BATT FLOAT
Battery
charging float
options
When
BATT FLOAT
is set to
Constant
, the default max charge voltage is 54.6V
and float is 54.2V, both at 25°C. Temperature compensation will be active
When
BATT FLOAT
is set to
AUTO,
the float voltage is set to 1.8V below the max
charge voltage. The default max charge voltage is 54.6V and default float is 52.8V,
both at 25°C
BATT COMP
Battery
temperature
compensation
Sets the battery temperature compensation to match the batteries you are using. It
can be set from 0 to -6 mV/°C/Cell in increments of 0.5. The factory default setting
is -5 mV/°C/Cell.
DATE FRMT
Date Format
Selection
Toggles the Alpha FXM date format between YY-MM-DD, MM-DD-YY, DD-MM-YY
YYYY-MM-DD, MM-DD-YYYY, DD-MM-YYYY, YY-TXT-DD, TXT-DD-YY, DD-TXT-
YY, YYYY-TXT-DD, TXT-DD-YYYY, DD-TXT-YYYY, YYYY-DD-TXT, YY-DD-TXT,
YYYY-DD-MM, YY-DD-MM. The factory default setting is MM-DD-YY.
CLOCK FRMT
Clock display
format option
Format to display time information: in 24 hour clock format or 12 hour clock (AM/
PM).
INV RECORD
Inverter record
clear
Clears the inverter counter and timer from the LCD system status menu.
CHGR CUR
Charger current
Charging current can be set to 0A or any value between 2 and maximum in
increments of 1A, where maximum = 15A for FXM1100/FXM2000 and 10A for
FXM650. (Charging current cannot be set to 1A).
When charging current is set to 0A, the charger will stop charging.
