POWER MANAGEMENT Menu
The Power supply unit menu allows you to view and manage the status of the system
power supply unit. All information is shown in 4 screens selectable with the UP and
DOWN arrows, the first of which summarises the status of the macros composing the
power supply section:
PSU global status  System power supply unit, consisting of all its components:
DISABLED  “Disablement” section
CUT-OFF  Imminent shutdown
FAULT  At least one fault active
OK  Operating properly
Main Power  Main power supply connected to the primary power mains,
status can be OK or FAULT.
Backup Power
 Backup power supply connected to the buffer batteries, the
status can be OK or FAULT.
Charger status
 Buffer battery charger; its status can be OK or FAULT.
The second screen summarises the status of the main power supply unit, which draws
the primary power supply from the primary power mains.
Mains: PRESENT  Primary power mains connected and present
ABSENT  Primary power mains disconnected and absent
Indicates the status of the system protection fuse from the primary power mains.
Fuse OK  Fuse intact
BLOW  Fuse blown or removed
For completeness, the value in volt of the internal primary power supply distributed to
all system components (Amplifiers, Charger, etc.) is indicated
The third screen summarises the status of the backup power supply unit, which draws
the secondary power supply starting from the battery pack.
Batt: PRESENT  Battery pack present and connected
ABSENT  Battery pack removed
SHORT  Battery pack in short-circuit
OPEN  Open wiring / battery pack disconnected
OVERTEMP  The battery temperature is too high
UNDERTEMP  The battery temperature is too low
The status of the battery protection fuse is indicated.
Fuse OK  Fuse intact
BLOW  Fuse blown or removed
The value in volt of the battery pack read by the system and the temperature in
degrees centigrade are indicated.
Presence of the impedance status of the battery pack:
Impedence: OK  Impedance of the battery pack detected and correct
NOT CALIB  Impedance of the battery pack not calibrated
ERROR  Impedance of the battery pack out of range, used
batteries or to be re-calibrated
WARNING 
Impedance of the battery pack near the fault
threshold
For completeness, the display indicates the measured impedance value and the
calibration value with the fault threshold in percentage.
The fourth screen summarises the operating status of the battery pack charger.
Charger: FAULT  Faulty charger
OK  Operating charger
It shows the details of the operating status:
Status: CIRCUIT FAIL  Faulty charging circuit
OVERTEMP  The charging circuit temperature is too high
IN CHARGE  The charging circuit is operating and the charge is in
