4.4.2.- POWER SUPPLY FAULTS
MAINS VOLTAGE DROPS
(110~230V voltage does not reach the power source)
Cause
110~230V voltage does not reach the power source.
Solution
Check that there is 110~230V mains voltage in the terminal strip for connecting the A.C.
source. The green led of the A.C. source must be lit. Check the status of the power supply
fuse (8 Amps). (See chapters 2.2.1 and 2.2.3)
MAINS VOLTAGE TOO HIGH
Cause
110~230V power supply is outside the permitted range.
Solution
Check that there is 110~230V mains voltage in the terminal strip for connecting the A.C.
source. The green led of the A.C. source must be lit. (See chapters 2.2.1 and 2.2.3)
NO BATTERY
(The battery is not connected to the control panel)
Cause
Either the battery is not connected to the control panel or it is connected incorrectly.
Solution
Check that the batteries are correctly connected to the control panel, and check the status
of the battery output fuse (5 Amps). Carefully examine the battery polarity and check that
they are connected in series. For normal operation, the voltage in the battery output, when
they are connected, should be between 22V and 28V. (See chapter 2.3.1)
BATTERIES OVERLOADED
(The batteries do not accept a charge)
Cause
The batteries have reached the end of their useful life.
Solution
Replace the set of batteries with new ones. For normal operation, the voltage in the
battery output, when they are connected, should be between 22V and 28V. (See chapter
2.3.1)
BATTERIES DISCHARGED
(The batteries are not charged)
Cause
The batteries are not charged, or they are not connected correctly.
Solution
Check that the two 12V batteries are connected in series, and wait for about 12 hours for
them to finish charging. If the fault persists, replace the batteries with new ones. For
normal operation, the voltage in the battery output, when they are connected, should be
between 22V and 28V. (See chapter 2.3.1)
CHARGER FAULT
(The battery charger doesn't work)
Cause
The battery charger does not charge the batteries This message is associated with faults
mentioned above, such as: MAINS VOLTAGE DROP, NO BATTERY, BATTERIES
OVERLOADED and BATTERIES DISCHARGED. This message is displayed 4 minutes
after the fault occurs.
Solution
Check the batteries’ connections and status as indicated above. If this fault is indicated,
but there is no other associated message, checks the battery charger fuse (1 Amp). (See
chapters 2.2.1, 2.2.3 and 2.3.1)
30V FAULT
(There is no 30V voltage at the 30V output from the Power Source)
Cause
The fuse for this output has blown due to a short circuit or excessive power consumption.
Solution
Check the connections for the 30V output and check how many elements, such as
repeaters, electromagnets, etc. are connected to it, in order to ensure that the maximum
permissible power consumption is not exceeded. (See chapters 1.5.4.1 and 2.2.3)
