Event Descriptions
There are a number of EVENTS that can be detected and recorded in
the EVENT HISTORY log. Some of these conditions can be damaging to
sensitive equipment, such as computers, resulting in data loss, system
crashes, or equipment failure. The Alpha CFR UPS completely protects your
equipment by responding to the following conditions:
Low Battery Warning - The batteries are near the end of their useful charge.
If AC Line power is not restored within a short period of time, output power will
be lost. All systems should be shutdown immediately to prevent loss of data.
Low Battery Shutdown - To prevent an over-discharge condition of the
batteries, the unit has shutdown. Output power is terminated in this condition.
Battery Voltage High - The charging voltage is higher than the threshold
setting for the batteries. This could be the result of a defective charger,
improper external battery connections, or defective batteries. Service the unit
or batteries to correct condition. Note: This condition activates the SERVICE
alarm, along with an audible alarm which can be cleared by pressing the
MUTE key.
Battery Charger Current High - The charger is outputting an excessive
amount of current. This condition could be caused by defective batteries or
improper external battery connections.
Failed Self-Test - The unit could not maintain output power while in the self-
test mode. Check the batteries and circuit breakers. Note: This condition
activates the SERVICE alarm, along with an audible alarm which can be
cleared by pressing the MUTE key.
Battery Fault - The battery charger is not able to supply the proper amount of
current or voltage to the batteries. This condition usually indicates that the
batteries are not connected or the BATTERY circuit breaker is switched OFF.
Glitch - A glitch is a fast, low amplitude line disturbance where the input
voltage drops momentarily. * *
Spike - A spike is a fast, high amplitude line disturbance where the input
voltage rises momentarily. * *
Sag - A sag is a slow, low amplitude line disturbance where the input voltage
decrease for a longer duration than a glitch. * *
Surge - A surge is a slow, high amplitude line disturbance where the input
voltage increases for a longer duration than a spike. * *
Brownout - A brownout is a slow, low amplitude line disturbance where the
input voltage decreases for a long period of time. * *
Brownout High - A brownout high (high overvoltage) is a slow, high
amplitude line disturbance where the input voltage increases for a long period
of time. * *
* * Indicates events that cause the UPS to operate in "LINE FAILURE" mode.
