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)
Possible operating modes:
ON LINE
ON BYPASS
ON BATTERY
OUTPUT OFF
ON MANUAL BYPASS
Pressing 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
LOADnotPROTECTED
LOAD 107%
LOADnotPROTECTED
TEMP TOO HIGH
LOADnotPROTECTED
VOLTAGE TOO HIGH
BATTERY CHARGER

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.
The normal operating mode. For more information see section 3.2.
Overload or failure situation. For more information see section 3.4.
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 3.5.
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 mains 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
After 24 hours of charging time, the battery voltage did not reach the normal
float voltage. This may be caused by faulty batteries, too many battery packs
connected or a charger fault.
