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:
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:
ON LINE
The normal operating mode. For more information see section 3.2.
ON BYPASS Overload or failure situation. For more information see section 3.5.
ON BATTERY For a detailed description of this mode see section 3.3.
OUTPUT OFF 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).
ON MANUAL BYPASS Service mode. For more information see section 3.6.
on ECO-mode 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:
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.
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
