First line: 'error'
Second line: specified as indicated below
The batteries are nearly discharged. Controlled shutdown of any
computer equipment is absolutely necessary at this point.
If the NetPro UPS is operating at 100% load, the shut-down procedure
should be completed within 2 minutes after the 'battery low' alarm
started. If only part of the output capacity of the UPS is used this period
can be longer, with aged batteries this period can be shorter.
When the batteries are fully discharged, the UPS is no longer able to
power the connected equipment.
NetPro 3000/4000 only: fan is blocked or defective.
The demanded power of the equipment exceeds the normal capacity of
the UPS. The message is displayed when 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
situation between 100-150% persists, the UPS can eventually also
switch to bypass operation. If a transfer to bypass is inhibited (due to
voltage or frequency errors of the mains supply), or if the bypass
function has been disabled (see 3.4.3) 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 output voltage drops below 207Vac. This situation can occur during
an overload, with either the bypass disabled or during battery operation.
If during a 'temperature' alarm the operating temperature of the UPS is
allowed to increase further, a high priority alarm will follow: the screen
message changes and red LED 'alarm' on the front panel illuminates. If
the UPS operates in 'on line' mode, it will switch to bypass mode (if
allowed, see explanation in section 'overload' above) until the
temperature is normal again*. If however the UPS operates 'on battery',
a shutdown will occur and output power is lost.
* If the UPS is equipped with an isolation transformer (NetPro+), the
temperature of the transformer may rise to an intolerable level during
bypass operation. In this case the UPS will shut down, too.
Input converter defective. Please contact your dealer.
