5.3.2 Status and Alarm Menu

The UPS alerts the user with a standard alarm screen that the operating mode has changed and/or that an alarm situation occurs:

ON LINE

ALARM PRESS UP

The actual operating mode, the possible modes are mentioned below. The lower line -if displayed- shows that an alarm occurred. More information can be retrieved with the 'up' key. If no further information is available, the second line is blank.

Possible operating modes:

The normal operating mode. For more information see section 3.2. Overload or failure situation. For more information see section 3.5. For a detailed description of this mode see section 3.3.

No power is delivered to the load. This can be the result of a command via the RS232 Port, or because no electric energy is available (utility failure, depleted batteries).

Service mode. For more information see section 3.6. ECO-Mode. See section 5.5.5

Depressing the 'up’ key from the standard alarm screen shows, in priority order, which alarms are active,. Scroll through the screens with the 'up' and 'down' keys. Alarm message texts can succeed each other. The following messages are possible:

LOADnotPROTECTED

CAP. C2 DEFECT

UPS OVERLOADED REDUCE LOAD

UPS OVERLOADED LOAD 143%

The output capacitor C2 is defective. Contact your dealer.

The load exceeds the rated output power of the UPS, and the output voltage can no longer be guaranteed. This text alternates with the following screen:

showing the actual load as % of the nominal UPS rating. These messages are displayed if the load is > 100%.

If the load exceeds 150% the UPS will immediately switch to bypass, assuming that the conditions for a transfer to bypass are fulfilled. If an overload condition between 100-150% persists, the UPS can eventually also switch to bypass operation due to temperature protection. If a transfer to bypass is inhibited (due to voltage or frequency errors of the utility supply) the UPS may automatically switch off within a few seconds (load dependent). Output power is lost at that moment. To avoid these problems, be absolutely certain that the power demands of the protected equipment are within the limits of the UPS.

TEMP TOO HIGH

LOADnotPROTECTED

VOLTAGE TOO HIGH

BATTERY CHARGER VOLTAGE TOO HIGH

BATTERY CHARGER TEMP TOO HIGH

The temperature of the heatsinks or output transformer is too high. As a result the output voltage may be transferred to bypass.

The operating temperature can rise to intolerable levels as a result of:

•extreme environmental temperature

•lack of proper ventilation

•an overload situation

•fan failure

If the UPS operates in 'on line' mode, it will switch to bypass until the temperature is normal again. If however the UPS operates 'on battery', a shutdown will occur and output power is lost.

The internal DC voltage is too high, internal failure

The output voltage of the battery charger is too high, internal failure

The battery temperature is too high due to a battery failure or a too high ambient temperature
