5.12 Event Descriptions (Alarms), continued
Several alarms can be triggered during the same event. If there is a loss of AC
line voltage, for example, the UPS may detect a glitch, low frequency and blackout.
Low Battery Warning (LO_BAT_WARN) - 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 (LO_BAT_SHTDWN) - To prevent an over-discharge
condition of the batteries, the unit has shutdown. Output power is terminated in this
condition.
Battery Voltage High (BAT_VOLT_HI) - 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 ALARM OFF or MUTE key.
Failed Self-Test (FAIL_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 ALARM OFF or MUTE key.
Battery Fault (BATT_FLT) - 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 (GLITCH) - A glitch is a fast, low amplitude line disturbance where the input
voltage drops momentarily (less than 8 ms). * *
Spike (SPIKE) - A spike is a fast, high amplitude line disturbance where the input
voltage rises momentarily (less than 8 ms). * *
Sag (SAG) - A sag is a slow, low amplitude line disturbance where the input
voltage decreases for 8 - 40 ms. * *
Surge (SURGE) - A surge is a slow, high amplitude line disturbance where the
input voltage increases for 8 - 40 ms. * *
Brownout (BROWNOUT) - A brownout is a slow, low amplitude line disturbance
where the input voltage decreases for a long period of time (greater than 16 ms). * *
Slow Surge (SLOW_SURGE) - A brownout high (high overvoltage) is a slow, high
amplitude line disturbance where the input voltage increases for a long period of time
(greater than 16 ms). * *
* * Indicates events that cause the UPS to operate in “LINE FAILURE” mode.
