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 4.5.2 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.
