Alarm Messages

 

 

Alarm

Meaning and

Message

Corrective Action in Brackets [ ]

AC INPUT

 

 

 

 

Input power out of tolerance

Frequency or voltage of the input power is outside the acceptable range. The

 

 

battery supplies power to the critical load through the UPS Module.

 

 

 

DC BUS

 

 

 

 

Charger in reduced current mode

Customer has selected reduced current operation of the charger from a contact

 

 

external to the UPS.

 

 

Battery charger problems

The battery is not being charged. The voltage produced by the charger is

 

 

insufficient to maintain a charge on the battery.

 

 

[Contact Liebert Customer Service and Support at 1-800-543-2378.]

 

 

Low battery warning issued

Battery has been discharging and the Low Battery Warning Time (factory set at

 

 

5 minutes, adjustable range 1 to 99 minutes) has been reached. Note time

 

 

stamp on alarm message.

 

 

[Follow appropriate procedures to shut down the critical load in an orderly

 

 

sequence.]

 

 

Low battery shutdown

Battery has discharged to the minimum allowable voltage and the UPS is shut

 

 

down. No power is being supplied to the critical load.

 

 

[When input power becomes available, perform a UPS start-up procedure.]

 

 

 

DC bus overvoltage

 

DC bus voltage has exceeded the specified limit and the charger has been

 

 

turned off. The charger will automatically restart when the DC bus voltage

 

 

returns to within tolerance.

 

 

[Contact Liebert Customer Service and Support at 1-800-543-2378 if this

 

 

condition persists for more than 2 minutes.]

 

 

 

BYPASS

 

 

 

 

Bypass frequency out of tolerance

Input power frequency is outside of the specified tolerance (adjustable range .5

 

 

to 5 Hz). Automatic transfers to the Static Bypass Line are prohibited.

 

 

[Do not operate the Rotary Switch while this condition is present.]

 

 

Load transferred to bypass due to

Critical load connected to the UPS has exceeded the UPS power rating. The

overload

 

load has been automatically transferred to the Static Bypass Line. Power to the

 

 

load is not being conditioned by the UPS. An automatic retransfer will be

 

 

attempted when the load is reduced.

 

 

[Determine cause of the overload and reduce the load.]

 

 

Load transferred to bypass due to DC

DC bus voltage has exceeded the specified limit. The load has been

overvoltage

 

automatically transferred to the Static Bypass Line. An automatic retransfer will

 

 

be attempted when the DC bus voltage returns to within tolerance.

 

 

[Contact Liebert Customer Service and Support at 1-800-543-2378 if this

 

 

condition persists for more than 2 minutes.]

 

 

Excessive retransfers attempted

Several automatic retransfer attempts (15 attempts during 20 minutes or less)

 

 

have been made to retransfer the load from the Static Bypass Line back to the

 

 

UPS. The UPS has not been able to consistently sustain the load because of

 

 

an overload condition or an inverter failure. The load will remain on the Static

 

 

Bypass Line. Power to the load is not being conditioned by the UPS.

 

 

[Check other messages for inverter failure. Determine cause of the overload

 

 

and reduce the load.]

 

 

 

Static Switch failure

 

A fault has been detected in the Static Transfer Switch. Automatic transfers to

 

 

the Static Bypass Line are prohibited.

 

 

[Contact Liebert Customer Service and Support at 1-800-543-2378.]
