System information (continued)

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.

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

MGETM GalaxyTM 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.

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.
