ATS/GTS Option
The ATS (automatic transfer switch) and the GTS (generator transfer
switch) are two separate optional add-on switching units for the FXM
family (FXM 650, 1100 and 2000). The ATS provides power and/or
bypass capacity (automatic or manual) so the operator may discon-
nect the FXM family of products from line power for easy removal
and servicing. In bypass mode, the loads are directly connected to
the line power without any conditioning. The ATS and GTS can be
used alone or together to allow the use of 3 different back-up sourc-
es (line, batteries and or generator). Refer to the ATS/GTS Installation
Manual (Alpha P/N 020-161-B0) for details.
WARNING
Make sure you have read and understood the instructions given in
the ATS/GTS Installation Manual before making any connection to
the supply.

Switching the FXM from Line mode to Inverter mode
You can also force the FXM to operate in the inverter mode by manu-
ally turning off the input circuit breaker. Doing so will effectively dis-
connect any line power to the FXM, simulating a power outage which
triggers the FXM to swtich to the inverter mode of operation.
Procedure
Turn off the input circuit breaker. The LCD shows1. INVERTER,
the status LED starts flashing to show the FXM is running on
backup battery power. Confirm that the load is receiving power.
Switching the FXM from Inverter mode to Line mode
The FXM remains in inverter mode for as long as the input circuit
breaker is turned off. Backup power is provided to the load until
the batteries are drained to a preset level which triggers the FXM
to shutdown automatically. If it is not necessary to operate the FXM
in inverter mode, you should switch the FXM back to Line mode as
soon as possible.
Procedure
Turn on the input circuit breaker. The FXM qualifies the line1.
power. The LCD displays RETRAN, then shows LINE, BUCK or
BOOST. The status LED turns on.
Note
If the FXM constantly switches between Inverter and Line modes due
to a noisy line, the FXM’s input parameters should be broadened
from normal to generator (See “Operating the Novus FXM, Sense
Type.” on page 40. Also See Specifications, “Boost/Buck/Line
Transfer Thresholds” on page 89).
In generator mode, the range of acceptable input frequency and volt-
age is expanded to accept the fluctuations created by a generator.

INVERTER Inverter When turned on, this forces the FXM to provide backup battery power to the
load. This can only be activated when the FXM is turned on and there is no
line power available. Also See “Adjusting and Controlling the Novus FXM, #31
Inverter On/Off.” on page 50.
INV BYPASS Inverter Bypass This function can only be turned on when the FXM is in line mode. When
turned on, this locks the FXM into line mode, turns off the battery charger and
makes the output voltage equal to the input voltage. This is done to:
Replace the batteries (See page 83).
OR
Allow the use of a break-before-make manual bypass switch so the FXM can
be shut off for maintenance or replacement without interrupting power to the
load.
SELF TEST Self Test This is the FXM’s self test. When it is turned on, the FXM is forced to verify
its proper operation by providing backup battery power to the load and then
switches back to Line mode. The default setting for the run time is 2 minutes,
but this can be changed in the RS-232 menus (See “Adjusting and Controlling
the Novus FXM #30: Self Test Options” on page 50.).
AUTO TEST Automatic Test If the GUI’s periodic self test is enabled (See page 56), this starts the test no
matter when it is scheduled to take place.
SHUTDOWN Shutdown When this function is turned on, the FXM’s inverter is shut off. The line is
disconnected from the load, so no line power is provided to it.
SENSE TYPE Sense Type This function can only be used when the FXM is in Standby or Shutdown
mode (See Figure 7. 2 ). This function toggles between:
NORMAL: The FXM can operate successfully with most line conditions.
or

VOLTAGE Voltage This lets you set the FXM’s output voltage setting to 120VAC, 230VAC or
220VAC. This should ONLY be done by a qualified technician acting under the
instructions of Alpha Technologies customer service department. Failure to
contact Alpha technologies before doing this procedure could result in voiding
of the warranty.
FREQUENCY Frequency The frequency can only be changed when the FXM is in Standby mode.
This lets you set the FXM’s frequency setting to 50Hz or 60Hz. This should
ONLY be done by a qualified technician acting under the instructions of
Alpha Technologies customer service department. Failure to contact Alpha
technologies before doing this procedure could result in voiding of the
warranty.
QUAL TIME Line Qualify Time This lets you set how long it takes for the FXM to return to Line mode after the
line has become requalified to make sure the line is stable. It can be set to 3,
10, 20, 30, 40 or 50 seconds. The factory default setting is 3 seconds. Also
See “Adjusting and Controlling the Novus FXM, #34: Line Qualify Time.” on
page 50.
BATT COMP Battery
Temperature
Compensation
This lets you set the battery temperature compensation to match the batteries
you are using. It can be set to -2.5, -4, -5 or -6 mV/°C/Cell. The factory default
setting is -5 mV/°C/Cell.
DATE SEL Date Format
Selection
This lets you toggle the FXM’s date format between YY-MM-DD or MM-YY-DD,
DD-MM-YY, YYYY-MM-DD, MM-DD-YYYY OR DD-MM-YYYY. The factory
default setting is MM-DD-YY.
INV RECORD Inverter Record
Clear
This clears the inverter counter and timer from the LCD’s system status menu
(See page 43). This does not clear the 100-event log in the RS-232 menus
(See page 54).
CHARGE CUR Charger Current This allows you to set the battery charger current to either 0A, 3A, 6A or 10A.
NOTE: If you set the battery charger to 0A, you will turn the charger off.
