TABLE 4 - BATTERY CHARGER FAILURE
The test is performed every second. The failure is noti fi ed when the test detects for more than 5 minutes the presence of mains power, but not the battery charging current.
Test frequency 1 second
Delay of failure noti fi cation 5 minutes
Signaling on occurence of failure The PWR SPLY FAILURE LED starts fl ashing
Signaling on noti fi cation of failure
The control panel display shows POWER SUPPLY FAILURE
The failure noti fi cation is stored in the failure folder and the relative counter is incremented
The PWR SPLY FAILURE LED turns on steadily
The GENERAL FAILURE LED starts fl ashing
The failure relay is activated
Reset of faillure noti fi cations The failure noti fi cations are reset after detecting the battery charging current for 5 minutes.
TABLE 5 - OVERVOLTAGE
The test is performed every second, the failure is noti fi ed when the test detects, for more than 60 seconds, that the power supply voltage required by the external
devices exceeds 30V.
Test frequency 1 second
Delay of failure noti fi cation 60 seconds
Signaling on occurence of failure The PWR SPLY FAILURE LED starts fl ashing
Signaling on noti fi cation of failure
The control panel display shows OVERVOLTAGE FAILURE
The failure noti fi cation is stored in the failure folder and the relative counter is incremented
The PWR SPLY FAILURE LED turns on steadily
The GENERAL FAILURE LED starts fl ashing
The failure relay is activated
Reset of faillure noti fi cations
The failure noti fi cations are reset after detecting, for 60 seconds, that the power supply voltage required by the
external devices has returned to the rated value of 30V.
TABLE 6 - LOW BATTERY
The test is performed only in case of power failure, with an interval of 1 second. The failure is noti fi ed when the test detects for more than 15 minutes a battery
voltage below 21.6V.
Test frequency 1 second
Delay of failure noti fi cation 15 minutes
Signaling on occurence of failure The BATTERY LED starts fl ashing
Signaling on noti fi cation of failure
The control panel display shows LOW BATTERY
The failure noti fi cation is stored in the failure folder and the relative counter is incremented
The BATTERY LED turns on steadily
The GENERAL FAILURE LED starts fl ashing
The failure relay is activated
Reset of faillure noti fi cations Failure noti fi cations are reset after detecting, for at least 30 seconds, a battery voltage above 22.8V.
TABLE 7 - DISCHARGED BATTERY
The test is performed only in case of power failure. If the test detects for 15 minutes a battery voltage below 18V, the power supply section disconnects the batteries
and shuts down.
Signaling 10 seconds before
power supply shut down
The control panel display shows BATTERY FAILURE
The failure noti fi cation is stored in the failure folder and the relative counter is incremented
The BATTERY LED turns on steadily
The GENERAL FAILURE LED starts fl ashing
The failure relay is activated
