ALARMS

ON BATTERY

When the UPS is operating on the batteries, the On-Battery LED will blink and the audible alarm will sound once every 10-seconds. The alarm will stop once the UPS returns to the On-Line operation.

LOW BATTERY WARNING

The UPS will sound two beeps every five-seconds when the battery reserve runs low. This condition will continue until AC returns or the UPS shuts down from battery exhaustion.

WEAK/BAD BATTERY

The UPS automatically tests the battery’s condition and will illuminate the Weak/ Bad Battery LED and sound the alarm. This alarm will be repeated until the batteries pass a self test. If the battery is bad or disconnected, the Weak/Bad Battery LED will illuminate and the alarm will beep three times every five-min- utes until the battery is reconnected or replaced. If the battery is weak, the Weak/Bad Battery LED will illuminate and the alarm will beep one time every ten-minutes until the battery is recharged or replaced. It is recommended that the UPS be allowed to charge overnight before performing a battery test to confirm a Weak/Bad Battery condition.

NOTE: If the UPS has a Weak/Bad Battery Alarm after reconnecting of replac- ing the batteries, the user must initiate a self test to clear the Weak/Bad Bat- tery Alarm. To initiate a self test see section 4 "SELF TEST".

OVERLOAD

When the amount of load attached to the UPS exceeds its power rating, the Overload LED will illuminate and the UPS will sound a constant alarm. This alarm will remain on until the excess load is removed or the UPS’s self protec- tion circuit shuts the UPS down.

UPS FAULT

When the UPS detects a hardware fault, the Fault LED will illuminate and the UPS will sound a constant alarm. The fault condition, in some instances, may be reset by turning the UPS OFF and then ON (see section 5 Troubleshooting).

FAN LOCK

AC Mode: If the fan becomes locked, the alarm will beep one time every two- seconds until the fan is unlocked.

Battery Mode: If the fan becomes locked, the alarm will beep one time every two-seconds for thirty-seconds, then the output will turn off, the alarm will sound continuously and the Fault LED will illuminate. The UPS must be turned off and the fan unlocked to clear the Fan lock Alarm.

COMMUNICATIONS PORT

The MBK-E series comes standard with a USB communication port.

NOTE: See the SentryII CD for the Power Monitoring Software installation. See the USB Driver CD for the USB installation.
