Keys menu 3, 2: battery test
This activates the cycle to check the state of efficiency of the battery, which lasts 8 seconds. Press key 8 to interrupt
the test and return to the basic menu before this time has elapsed.
The battery test cycle lowers the rectifier output voltage so that the battery can be evaluated with the real supply on
the load even when the power supply voltage is present.
The rectifier output voltage is only lowered if the bypass line voltage is present, in order to avoid any loss of output
load without the support of the bypass.
The battery test cycle is activated:
- manually;
- automatically every 60 sec. after each failed test (for three times), or each time the system is
restarted;
- automatically every 24 hours from system start-up;
- automatically in non visible mode during operation without mains power supply.
At the end of each test, the alarm is activated if the voltage measured is lower than the calculated voltage; the charge
value stored and the backup time indicated are subsequently halved. A new test is performed 60 sec. after activation
of the alarm and if the result is negative the alarm is activated once again for another 60 sec.
The alarms continue to halve the charge value stored until the calculated battery voltage is less than the voltage
actually measured. In practice, this battery control system produces an alarm each time the battery is seen to have
less than half of the expected charge. If this alarm is on PERMANENT, it indicates that the battery is inefficient, the
battery circuit is interrupted, the battery disconnector has remained open or one of the protection device fuses has
been triggered. If this alarm is on TEMPORARY, it indicates a reduction in the efficiency of the battery; the more
frequent the alarm, the more serious the problem.
Disabling the BATTERY TEST: press keys 3, 5: “CUSTOMIZING”, insert code 323232, with battery test
disabled the code o=02 will be shown in the basic menu of the display. To reactivate the test, insert code
323232 again.
