5.0 Operation
5.1 Display features
5.1.1 On / Test / Alarm disable pushbutton
The On / Test / Alarm disable pushbutton is used to control activation of the UPS and to
energize the load. Once the UPS is energized, pressing the button will initiate a battery
test. This will force the UPS to operate on-battery for a brief time during which the UPS
determines the strength of the battery. When the UPS is on-battery, this button may be
pressed to silence the utility failure audible warning.
5.1.2 Power standby pushbutton
When held pressed for a second, this control will deenergize the UPS and all protected
loads. However, operation of the UPS's battery charger is unaffected by this control.
5.1.3 On Line indicator
Illumination of the On Line indicator means that the load is being supplied conditioned
power derived from the utility service. The indicator blinks during the battery test.
5.1.4 On Battery indicator
Illumination of the On Battery indicator means that load has been transferred to power
derived from the UPS's battery and that utility voltage is not within normal limits.
5.1.5 Smart Boost indicator
Illumination of SmartBoost indicator means that the SmartBoost circuitry has been
engaged to compensate for unacceptably low line voltage. The UPS is capable of
operating in this mode continuously without draining charge from the battery.
5.1.6 Replace Battery indicator
Illumination of the Replace Battery indicator means that the automatic battery test has
found that the battery is weak and requires replacement. The indicator is extinguished
following a successful battery test.
