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.
The main DC-capacitor needs replacement due to aging or failure
Due to a failure the output converter's output is not available. As a result the load
may have been transferred to bypass.
The remaining runtime is zero. As a result the load may have been transferred to
bypass.
The remaining run time is less than the set time (standard 2 minutes). This text
alternates with the following screen:
The output voltage can be lost after the indicated time due to discharged battery.
Controlled shutdown of any computer equipment is absolutely necessary at this
point. (Using the RS232 or SNMP communications interface, this procedure can be
initiated automatically on unattended systems). If the UPS operates at 100% load,
the shutdown procedure should be completed within 2 minutes after the 'battery
low' alarm started. When the batteries are fully discharged, the UPS is no longer
able to power the connected equipment.
The static bypass circuit breaker (rear panel, 9) is in 'off' (down position): no bypass
voltage available. Utility voltage is available. If not manually operated, this may
have been caused by an overload situation.
The utility circuit breaker (rear panel, 8) is in the 'off' (down position): no line voltage
available, bypass voltage is available. If not manually operated, this may have been
caused by an internal system failure.
The internal battery fuse is defective; this may have been caused by an internal
system failure. This alarm also appears if no batteries are installed.
The (custom-built) battery extension set has been disconnected from the system:
its energy reserve is not available. See 4.4.2 step 12 for details.
The batteries are (almost) chemically worn out. If the batteries are aged, they must
be replaced as soon as possible to ensure full protection for your equipment (see
section 8.3).
The utility voltage or utility frequency are outside UPS input tolerance (see chapter
10, specifications)
The utility voltage or utility frequency are outside bypass input tolerance but inside
UPS (rectifier) input tolerance (see chapter 10, specifications). Bypass operation is
inhibited: if for whatever reason the output converter is unable to deliver the
required output, output power is lost.
