Controls (all models):
The primary front panel user controls consist of one input circuit breaker and three push-buttons:
The switch located to the right of display is the main input circuit breaker and controls the connection
of utility power to the UPS and its internal battery charger.
.
The three buttons located to the left of the LCD display are for primary manual control and program-
ming of the UPS. From top to bottom they are designated "Function/TEST", "Set/Alarm Silence", and
"Bypass".
Function/Test Button
This button has two functions:
1
Initiates internal UPS Setup mode to allow for configuration changes. Setup mode is initiated
by pressing both the "Function/Test" and Set/Alarm buttons down and holding them for one
second.
2
Manual Battery Test - If depressed for less than three seconds, it initiates an immediate
battery test.
Manual Battery Test Description
- When the UPS is operating normally from utility power, pressing
the test button will cause the UPS to test the voltage status of the batteries for 10 seconds. During
that period, the battery, if first determined to be good, will supply power to the UPS. Should defective
batteries be detected, the audible alarm will sound one long tone, and the UPS will continue to
operate from the utility voltage, without going to battery mode. During the battery test, the output of
the UPS will not be adversely affected.
Set/Alarm Silence Button
This button has three functions:
1
Disables the audible alarm buzzer
2
Scrolls the display through the various UPS parameters.
3
Sets configuration changes (when pressed in setup mode only).
Disable the Audible Alarm
- Pressing the button for one second will turn off the audible alarm. This
will cause future notification of minor alarms to be silenced.
NOTE!
THE FOLLOWING ALARMS CANNOT BE SILENCED:
OVER TEMPERATURE, PFC OVER CURRENT, INVERTER OUTPUT OVER LOAD,
LOW BATTERY AND UPS OR CHARGER FAILURE.
How to Display The UPS Parameters
- Repeat pressing of the Set/Alarm button will cause UPS
input and output parameters to be displayed on the lower portion LCD display in the following order.
The input voltage, output voltage, output frequency, battery voltage, percentage of output load, input
current, internal UPS temperature and the output current.
