FAULT: Low battery capacity, Control Unit xx
Battery (in Control Unit no. xx) internal resistance > 0.5 Ω.
The "Resistance in battery circuit" value is shown in menu H5/A4
The battery might be too old.
•
• Battery cables are long and the conductor is less than 2.5mm²
Check / adjust the power supply voltage (24 V
•
Check the charging voltage over the battery respectively (13.5-
•
13.8 depending on the actual charging step).
• Check the voltage over a disconnected battery (fully charged >
13 V).
In the New Zealand convention only: The battery charging is
•
turned off 60 minutes every 24th hour to perform auto battery
test. A battery voltage < 24.4 V during these 60 minutes will
generate a fault.
If a fault is generated it will automatically be Serviced after
these 60 minutes.
The battery should normally be replaced in the due time.
Note: The 5012 continuously monitors the batteries and generates
battery fault within 60 seconds.
FAULT: Low battery capacity, Technical number xxxxxx
Battery in external power supply 4466 unit no. xxxxxx internal
resistance > 0.7 Ω.
• The battery might be too old.
Check / adjust the power supply voltage (24 V
•
• Check the charging voltage over the battery (13.5-13.8
depending on the actual charging step).
• Check the voltage over a disconnected battery (fully charged >
13 V).
The battery should normally be replaced in the due time.
NOTE: The battery check is performed every 60 sec, i.e. the fault
status will be "corrected" within 60 sec..
FAULT: Low voltage, Control Unit xx
System voltage < 21.0 V
supply output voltage, it must be 24 V
24 if required.
Note: A Control Unit powered by only the battery back-up will shut down
at a battery voltage of 20.6 V, in order to avoid damaging the batteries.
When this fault is detected, the log is automatically saved to flash, in
order to keep the log intact after a power failure.
FAULT: Low voltage, technical number xxxxxx
System voltage < 21 V
Check the power supply output voltage, which must be 24 V
Replace power supply if required.
FAULT: Mains, Control Unit xx
The fault is detected within 1-300 minutes
• Loss of mains, i.e. no 230 V
• Blown mains fuse.
• Blown fuse F1 on main board. Fuse T6.3A H 250V (5x20 mm
ceramic).
When this fault is detected, the log is automatically saved to flash, in
order to keep the log intact after a power failure.
32 The time is programmable via EBLWin. Default value is 30 minutes.
