System information (continued)

Glossary of information

descriptors

(data words at address 40 to 4E)

Every bit is listed according to the

following format:

bit address: description

(bit = 0 / bit = 1).

Word address: 40

400: battery circuit breaker

(0=open/1=closed)

Battery protection circuit breaker

"QF1" is located near the battery

and is "on" (closed) during normal

operation. When it either trips or is

turned "off" (open) the load is no

longer protected since battery

power is no longer available if

Mains 1 fails.

401: battery discharging (0=not

discharging/1=discharging)

The inverter powers the load.

Mains 1 is either not available or

outside tolerances and the inverter

is battery powered.

402: minimum battery voltage

(0=not reached/1=min. volt. fault)

A fault indicates that the minimum

battery voltage has been reached

during Load on battery and the

inverters it supplies are stopped. If

Mains 2 is not available, which is

generally the case, the load not

longer receives power.

403: low battery shutdown

warning (0=not reached/

1=warning)

The warning indicates that the end

of backup time is imminent. It is

only applicable when the inverters

operate on battery power.

404: battery temperature

(0=normal/1=outside tolerances)

This information only exists if the

system is equipped with the

"Temperature Monitor" option. It

tells the user that the temperature

of the battery is outside the

allowable range. The rectifier-

charger circuit is switched so that

the battery charging current

becomes zero. The battery is no

longer being recharged (battery

protection).

405 : Mains 1 voltage (0=normal/

1=outside tolerances)

Indicates that the Mains 1 power

supply voltage is outside tolerances

and the inverter on battery power.

406 : battery room ventilation

(0=no fault/1=fault)

Informs the user of a battery room

ventilation fault. The rectifier-

charger circuit is switched so that

the battery charging current

becomes zero. The battery is no

longer being recharged. It prevents

vented led-acid batteries from

giving off hydrogen gas The user

must remedy the ventilation

problem.

407: battery charging (0=not

charging/1=charging)

Informs the user whether the

battery is currently being recharged

(only valid for vented lead-acid

batteries).

408: rectifier-charger status

(0=off/1=on)

Gives the status of the rectifier-

charger circuit. It stops every time

Mains 1 power fails. In this case the

load is battery powered via the

inverter.

409: major rectifier-charger fault

(0=no fault/1=fault)

Informs the user of a major rectifier-

charger fault requiring after-sales

servicing.

40E: Mains 1 input switch

(0=open/1=closed)

"Q1" Mains 1 input switch which

powers the rectifier-charger.

Normally the switch is closed or

"on". The switch can be opened to

disconnect the unit from Mains 1 for

servicing.

Word address: 41

411: 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 off" 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.

412: rectifier-charger input

voltage (0=normal/1=outside

tolerances)

The rectifier-charger stops

operating when the Mains 1 phase-

to-phase voltage is outside

tolerances.

413: rectifier-charger input

frequency (0=normal/1=outside

tolerances)

The rectifier-charger stops

operating when the Mains 1

frequency is outside tolerances.

417: gradual rectifier-charger

shutdown (0=not activated/

1=activated)

Indicates that the rectifier-charger

received an external command to

gradually stop operating (e.g.

gradual load-shedding when using

power from engine generator sets).

419: engine generator set current

limiting (0=not activated/

1=activated)

Informs the user that the rectifier-

charger has received an external

command to limit the current drawn

from Mains 1. The additional power

required by the inverter is supplied

by the battery (which discharges).

Example: operating from a

generator that delivers insufficient

power.

41A: battery current limiting

(0=not activated/1=activated)

The rectifier-charger received an

external command to limit the

current that charges the battery.

Normal battery charging is resumed

when Mains 1 returns.

Example: operating from a

generator that delivers insufficient

power to supply load and charge

batteries.

Note: the current limit is

programmable.
