LCD Shows Meaning Description
INVERTER Inverter When turned on, this forces the UPS to provide backup battery power to the load. This is
usually activated when the UPS is turned on and there is no line power available.
INV BYPASS Inverter Bypass This function can only be turned on when the UPS is in line mode. When turned on, this
locks the UPS into line mode and makes the output voltage equal to the input voltage.
This is done to:
Replace the batteries (See Section 3.3).
OR
Allow the use of a break-before-make manual bypass switch so the UPS can be shut off
for maintenance or replacement without interrupting power to the load.
BATT TEST Battery Test This is the UPS’s self test. When it is turned on, the UPS 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 Section 4.3, #30 “Battery Test Options”).
AUTO TEST Automatic Battery Test If the GUI’s periodic battery test is enabled (See Section 4.6), this starts the test no
matter when it is scheduled to take place.
SHUTDOWN Shutdown When turned on, the UPS’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 UPS is in Standby or Shutdown mode (See
Figure 3.2.2). This function toggles between:
NORMAL: The UPS can operate successfully with most line conditions.
OR
GENERATOR: The UPS’s input voltage and frequency parameters are expanded so the
UPS can work with the uctuations caused by a generator or noisy line.
FUNC MODE Functional Mode The functional mode can only be changed when the UPS is in Standby or Shutdown
mode (See Figure 3.2.2). This function toggles between:
Automatic Voltage Regulation (AVR): The buck and boost modes are turned on.
OR
QUALITY: The buck and boost modes are turned off, the input voltage is the UPS’s
output voltage. The range of acceptable input voltage is narrowed to 100 ± 2VAC to 130 ±
2VAC. If you are connecting an Alpha Technologies’s Automatic Transfer Switch to trafc
intersection equipment, then the UPS MUST be switched to quality since most trafc
equipment cannot handle the high voltage output of the UPS when it is in AVR mode.
VOLTAGE Voltage This lets you set the UPS’s output voltage to 120VAC, 230VAC or 220VAC. This
should ONLY be done by a qualied 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 UPS is in Standby mode. This lets you
set the UPS’s frequency to 50Hz or 60Hz. This should ONLY be done by a qualied
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 UPS to return to Line mode after the line has
become requalied. It can be set to 3, 10, 20, 30, 40 or 50 seconds. The factory default
setting is 3 seconds.
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 UPS’s date format between YY-MM-DD or MM-YY-DD or DD-
MM-YY. 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
Section 3.7). This does not clear the 100-event log in the RS-232 menus (See Section
4.5).
CHARGE CUR Charger Current
Setting
This lets you select the battery charging current. It can be set to 0, 3, 6 or 10. If set to 0,
the charger will be disabled.
