Diagnostics and fault solutions
6.1
Battery disconnected or
inefficient
The battery is not connected or has failed the battery efficiency test (EN 54-4:1997 A2 amendment).
1. Allow the batteries to charge for several hours.
2. If the fault signal persists, disconnect the batteries from the station and test them separately.
3. If only one of the batteries has a voltage below 12.5 - 13 V:
• Replace the faulty battery only.
• Allow the batteries to charge for several hours.
• Check that the fault has cleared.
4. If both batteries have a voltage of 12.5 - 13 V, it means they are both inefficient (even though the
voltage without load is correct).
• Replace both batteries.
• Allow them to charge for several hours.
• Check that the fault has cleared.
6.2
Low Battery
The batteries are running low.
This signal should be present only during primary power source failure (Mains 230V
). Mains power must
be restored in order to charge the batteries.
6.3
Loop faults and testing
The station shows the status of the loop and the presence of any fault or short-circuit on it via the LEDs on
the front panel (Figure 7 - Front panel, [D] and [E]).
For further details, see the analog control panel that supervises the loop.
6.4
Earth fault
In the case of voltage dispersion to earth, this fault is indicated by the LED on the front panel (Figure 7 -
Front panel, [C]) and by a flashing of the “DL2” yellow LED on the power-supply unit (Figure 6 - Switching
power supply, [E]).
This fault signal can be disabled by disconnecting the respective jumper (Figure 6 - Switching power
supply, [F]).
