"Monitor" alphanumeric display
List of secondary alarms
This message is automatically displayed for five seconds, alternating with the preceding. It indicates the remaining battery
time in minutes prior to inverter shutdown. The calculation takes into account:
– the percentage of full rated load power being drawn;
– the type of battery;
– battery temperature;
– battery age.
This message replaces the "Mains 1 problem, load on battery" message when battery voltage reaches the "low battery
shutdown" warning level. It alternates with the message described above, "remaining battery time…".
The user must then rapidly take measures to secure the load (load shedding, file saves and shutdown, etc.). In the next one
to two minutes at most, the inverter will shutdown and the load will be interrupted.
Two low battery thresholds exist:
– a battery voltage threshold, which is slightly above the threshold causing an inverter shutdown (this threshold can be
disabled);
– a time threshold, which refers to an adjustable value of the time remaining before effective end of battery power.
This message signifies that the battery circuit breaker is open and the inverter shut down. The cause of the alarm is in the list
of secondary alarms (see next page).
These alarm messages may be consulted by pressing the "alarms" ("!") button when the "!" character appears at the end of
a general alarm message.
The "alarms" ("!") button can then be used to read the other alarms from the list.
The remote emergency-shutdown button has been pressed with as a result:
– shutdown of the inverter;
– shutdown of the rectifier/charger;
– opening of battery circuit breaker QF1;
– transfer of the load to Mains 2.
To ensure full powering down of the system, this button must also open the external upstream circuit breakers supplying
Mains 1 and 2.
The load has been transferred to Mains 2 and is no longer protected.
Mains 2 voltage is outside tolerances. Transfer of the load from the inverter to Mains 2 or vice-versa will result in
an interruption of the supply of power to the load.
Mains 2 voltage is outside tolerances. Transfer of the load from the inverter to Mains 2 or vice-versa will result in
an interruption of the supply of power to the load.
