"Monitor" alphanumeric display (cont.)
Alarm display and buzzer reset
When the control panel has not been used for ten minutes, the alphanumeric display presents a general message
Display of alarms
indicating the general status of the cubicle or the system.
If there are no alarms or problems, and the load is correctly supplied by the inverter, the display indicates:
LOAD PROTECTED
POWER SUPPLY OK
If there is a problem, the screen first displays a general alarm, then if applicable, a list of secondary alarms may be obtained by successively pressing the "alarms" button ("!"). See the lists below.
For the local "Monitor" option,
button 11 on the hidden control panel stops the buzzer.

(LAST ALARM MESSAGE)
!
This message is displayed only if the buzzer has been activated. It is a prompt to consult the list of current alarms by pressing the "alarms" ("!") button after having read each message.
The last alarm message is not followed by the blinking "!" character. If the "alarms" ("!") button is pressed again, the system returns to the initial screen.
For the remote "Monitor" option ("Tele Monitor"), the "!" button stops the buzzer.
Note:
The existence of another alarm in the list is indicated by the blinking "!" character at the end of a message. The last alarm in the list is not followed by the blinking "!" character at the end. If the "alarms" button is pressed again, the system returns to the initial screen.

LOAD PROTECTED
POWER SUPPLY OK
This is the normal display when there are no alarms or problems and the load is correctly supplied by the inverter.
LOAD PROTECTED
PROBLEM... !
The load is supplied by the inverter, but a minor problem requiring servicing has occurred. The cause of the problem is contained in the list of secondary alarms (see next page).
MAINS 1 PROBLEM
LOAD ON BATTERY !
The load is supplied by the inverter, but Mains 1 is down or outside tolerances and power is supplied by the battery.
REMAINING BAT. TIME
__MN %KW LOAD =___
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.
LOW BATTERY
SHUTDOWN IMMINENT !
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.
ALARM ...
!
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).
