5 Maintenance
The charging station relies on its cooling surface in order to be able to fulfil its technical data requirements. The heat
dissipator must therefore be inspected for dirt accumulation and cleaned if necessary.
Cables must be inspected from time to time for corrosion. Their contact resistance increases if they are corroded and the
contacts can become so hot that faults can occur.

7 Malfunctions and fault finding
The charging station has been designed for many years of continuous use. Faults can however occur. The description
of some common faults that follows should help the electrician and the operator to diagnose these faults, so that the
system can be brought into operation as quickly as possible and unnecessary expense can be avoided. Of course not all
possible causes of faults can be listed. However you will find here the most common causes of faults covering the
greater proportion of the incidences of faults in connection with the charging station. Do not send the charging station in
until you have established that the malfunction is not one of those described here.
The charging station is protected against destruction by a variety of measures. Nevertheless great care should be taken
to ensure that the charging station is operated correctly. Some of the malfunctions are signalled by the display. However
these faults can only be signalled if the system has been properly installed for them. If faults other than those described
should occur, then please first check that the charging station is connected to the module and the batteries at the correct
terminals and with the correct polarity.
Fault reporting on display
Meaning Remedial action
No display No current supply, electric power
supply may be defective or it is night-
time and there is no battery
connected
Ambient temperature <0°C
Storage temperature above or below
limits of range
•
Check connections
•
Check if module is supplying current or
if a battery is correctly connected
•
Check operating temperature
•
Install control unit again, disconnecting
all batteries and module and connecting
again in the correct order
OVERCURRENT GDN
DISCONNECT ALL Overcurrent was found at output,
caused by incorrect procedure on
connecting outputs in parallel
•
Install control unit again, disconnecting
all batteries and module and connecting
again in the correct order
Line 1 Line 2
POLARITY ERROR Battery was connected with reverse
polarity
•
Check battery connection for correct
polarity
BATT.DEF._C xxxAh Defective battery or battery with
incorrect nominal voltage e.g. 6V
connected
(see Chapter 2.2.3.3; Page 6)
•
this battery should be replaced
•
observe nominal voltage of battery
DEEP.DISCH.xxxAh A sulphated battery was connected
with details of Ah already charged
see Chapter 2.2.3.2; Page 6)
•
this battery is old or was deep
discharged
•
the owner of the battery should take
precautions against deep discharge.
