◗ malfunctions:
◗ ◗ static switch cubicle ventilation
fault,
◗ ◗ static switch control fault,
◗ ◗ environment faults:
◗ ◗ battery temperature outside
tolerances,
◗ ◗ overload exceeding 5%,
◗ ◗ Mains 2 voltage, frequency or
phase outside tolerances with
respect to inverter.
4C6: unsafe operation, load
unprotected (0=safe/1=unsafe)
Indicates that:
◗ Mains 2 powers the load due to
inverter shutdown (manual or due
to an overload or internal fault) or
due to opening "Q5N" at the
inverter output;
◗ not able to rely on battery backup
because circuit breaker "QF1" is
open.
Note: for parallel connected
inverters this only refers to the
specific unit. The load may still be
protected because more than one
inverter is supplying power.
4C7: operating on battery power
(0=no/1=on battery power)
Indicates that the unit is operating
on battery power because:
◗ Mains 1 voltage failure or dip;
◗ insufficient Mains 1 power (e.g.
engine generator set) with extra
energy required supplied by the
battery.
4C8: emergency off switch
(0=not activated/1=activated)
Normally-closed switch connected
to the units. When activated, the
rectifier-charger circuits and the
inverters stop operating. The "QF1"
battery circuit breaker is also
opened.
If the "emergency stop" also tripped
the protection devices to
disconnect the units from Mains 1
and Mains 2, the load no longer
receives power and the units are
completely disconnected.
4C9: power supplied via SS or
K2S (0=open/1=closed)
Indicates that the static switch or
the mechanical switch on the Mains
2 backup line is closed. The load is
supplied by Mains 2.
Glossary of
telemonitoring
information descriptors
(data words at address 50 to D4)
Word address: 50
The causes of high transition
alarms followed by a call from the
UPS site to the central monitoring
site are logged in this word.
Word structure is similar to that of
word 4C.
Word address: 51
The causes of low transition alarms
followed by a call from the UPS site
to the central monitoring site are
logged in this word.
Word structure is similar to that of
word 4C.
Word address: 52
520: invalid telephone number
for main telemonitoring site
(0=valid / 1=invalid)
Indicates that calls from the UPS
site to the central telemonitoring
site consistently fail. The number of
the telemonitoring site is therefore
declared invalid and no longer
used. A second set of calls is then
undertaken using the backup
number.
The telephone number is
reinstated:
◗ on reception of a new
communication configuration using
the Soft Tunor after-sales-support
computer tool,
◗ when the "GTCZ" or "GT2Z"
communication board is de-
energised.
528: invalid telephone number
for secondary telemonitoring site
(0=valid / 1=invalid)
Indicates that calls from the UPS
site to the secondary telemonitoring
site consistently fail. The number of
the telemonitoring site is therefore
declared invalid and no longer
used.
4CA: inverter connected
(0=disconnected/1=connected)
Indicates that the inverter is in
operation and supplying the load.
Word address: 4D
4DD: cubicle ventilation (0=no
fault / 1=fault)
Indicates to the user that ventilation
in a cubicle is incorrect due to a fan
fault or shutdown. This fault does
not result in UPS shutdown. This
information is available only on
U.S. versions of the
MGE
TM
Galaxy
TM
6000 UPS.
Word address: 4E (summary
of communication interface
information)
4E9: communication interface
test error (0=no error/1=error)
Error free communications can no
longer be guaranteed.
4EA: unit in configuration mode
(0=no config./1=config)
The after-sales "Soft Tunor"
computer software is connected to
the cubicle, blocking all remote
commands.
4EB: remote setting (0=no
setting / 1=setting)
Indicates to the user that the Soft
Tunor after-sales-support computer
tool has been connected to the
communication channel.
4EC: invalid measurements
(0=valid/1=invalid)
The communication interface
receives invalid measurement data
and status information from the
cubicle.
4EF: change in status (0=no
change / 1=change)
Indicates a change in status of at
least one indicator between two
reads of logical data. This
information can be reset by the
device connected to the
communication channel.
