7-1 - Failure noti fi cations of the power supply section
TABLE 1 - PRIMARY POWER SUPPLY FAILURE
The test is performed every second. The failure is noti fi ed when for the preset time the mains power is missing.
Test frequency 1 second
Delay of failure noti fi cation Programmable from 0 to 30 minutes
Signaling on occurence of failure
The MAINS PWR OK LED turns off
The PWR SPLY FAILURE LED fl ashes
Signaling on noti fi cation of failure
The control panel display shows MAINS 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 the preset time, that the mains power voltage has been restored.
N.B. The MAINS PWR OK LED follows the state of mains power immediately without any delay.
TABLE 3 - BATTERY HIGH IMPEDANCE
The test is performed only in the presence of mains power, with an interval of 30 minutes, on each battery.
The failure is noti
fi ed if the test detects an impedance above the failure threshold (1,5 Ω which cannot be changed).
Test frequency 30 minutes
Delay of failure noti fi cation 2 hours
Signaling on occurence of failure The BATTERY LED starts fl ashing
Signaling on noti fi cation of failure
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
Reset of faillure noti fi cations
The failure noti fi cations are reset after detecting, for 30 seconds, that the impedance of the battery has returned to
a value below the failure threshold.
TABLE 2 - SECONDARY POWER SUPPLY FAILURE
The test is performed only in the presence of mains power, with an interval of 10 seconds, on each battery.
The failure is noti
fi ed if the test detects for 5 minutes a battery voltage without load below 10V.
Test frequency 10 seconds
Delay of failure noti fi cation 5 minutes
Signaling on occurence of failure The BATTERY LED fl ashes
Signaling on noti fi cation of failure
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
Reset of faillure noti fi cations The failure noti fi cations are reset after detecting, for 30 seconds, a battery voltage without load above 10V
