TROUBLESHOOTING

ALARM CODES

Using a sophisticated self check system, the UPS can verify and indicate on the display panel any faults
and/or malfunctions that may occur during the normal operation of the device. In the event of a problem, the
UPS indicates this by displaying the code and the type of alarm (FAULT and/or LOCK).

FAULT

FAULT signals can be subdivided into three categories.

Faults: these are “minor” problems that do not stop the UPS but reduce performance or prevent the

use of some of its functions.

CODE

DESCRIPTION

A06

Sensor1 temperature less than 0°C

A08

Sensor2 temperature less than 0°C

A11

Input relay locked (does not open)

A54

Load > preset user threshhold

A61

Batteries to be replaced

A62

A63

Alarms: these are more critical problems than faults since if they persist, even for a very short time,

they may cause the UPS to stop.
