2.5 Indicator leds:
ON Led
This led is ON when the Control Unit is powered.
Fault Led
Yellow led that is ON in case of a Power Supply Fault. When
this indication is activated, the C and NC contacts of the fault
relay will be closed.
MAINS SUPPLY FAULT Led
Power Supply is not detected by the Control Unit and it is
powered by batteries. The internal led BAT-DIS is also
activated.
The led is ON immediately after detecting power. However, the
fault relay signal and the FAULT led do not activate until the
power supply fault remains for more than 8 minutes.
BATTERY FAULT Led
Battery is not detected by the Control Unit or the battery voltage
is below 22.4 Vdc, i.e., the 50% of its capacity.
The FAULT Led and the fault relay signal are also activated.
In case the internal led LOW BAT is flashing it means that the
battery voltage is close to 22.4 Vdc.
When the battery voltage is lower than 20.4 Vdc, both outputs,
PSO1 and PSO2, and the Output 1 and 2 leds will indicate a
fault condition.
The FAULT Led and the fault relay signal are also activated
BATTERY CHARGER FAULT Led
This led is on when there is a battery charger fault.
