Power supply
ZAFIRPWS2/5
LED
Fixed network It indicates that the electrical network supply fails with not enough voltage.
Battery off This anomaly is detected when the voltage of the control circuit is in the
range of 22~28Vdc.
Fixed network It indicates that the electrical network supply fails exceeding voltage.
Battery off This is detected because voltage of control circuit is over 31 Vdc, and 30
Vdc output is cut.
Fixed network
It indicates that voltage of control circuit is below 22 Vdc. 30 Vdc Output is
(780mHz) cut.
Fixed network
It indicates that the FUS2 30V of 4 A has been opened. This anomaly is
Battery off
detected by the lack of output voltage of 30V.
Fixed network
Battery off It indicates that the output voltage of 30V is out of range 20~30,5Vdc.
Fixed network
It indicates a fault in the battery charger. Disconnecting batteries, the output
Battery off
voltage of battery is out of range 27~29Vdc.
Fixed network
It indicates that FUS3 BATTERY of 4A has been opened. This anomaly is
Battery off
detected by the lack of voltage at the output battery.
Fixed network It indicates that the battery voltage is below 21Vdc. This anomaly is
Battery off detected by checking the voltage of the batteries when disconnected from
the control panel.
Fixed network
Battery off It indicates that the batteries are not connects or connected incorrectly.
Fixed network
Battery off It indicates that the internal resistance of the battery exceeds 0,47Ω.
LED
Network off It indicates that there is not electrical network supply, and batteries are
Fixed battery working with low voltage.
Control circuit is fed under 22 Vdc with only low battery voltage.
Network off
It indicates that FUS2 30V output of 4A is open. This anomaly is detected
(12Hz) because the lack of voltage in the 30 Vdc output.
Network off
It indicates that 30V output is out of the voltage range 20 ~ 30,5V.
(12Hz)
Network off
It indicates that battery voltage is under 21 V, and 30 V output is cut. This
fault is detected by measuring batteries voltage disconnected of the
(780mHz)
equipment.
