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
407:battery charging (0=not charging/1=charging) Informs the user whether the battery is currently being recharged (only valid for vented
408:
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
Informs the user of a major rectifier- charger fault requiring
40E: Mains 1 input switch (0=open/1=closed)
"Q1" Mains 1 input switch which powers the
Word address: 41
411:emergency off switch (0=not activated/1=activated)
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:

Indicates that the
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
Example: operating from a generator that delivers insufficient power to supply load and charge batteries.
Note: the current limit is programmable.
