Service and maintenance
4.1
Maintenance / cleaning
The device needs no maintenance. Cleaning may be needed for the internal fan, the frequency of cleanse is
depending on the ambient conditions. The fan serves to cool the components which are heated by the inherent
power loss. A heavily dirt filled fan can lead to insufficient airflow and therefore the DC output would switch off too
early due to overheating or possibly lead to defects.
Cleaning the internal fans can be performed with a vacuum cleaner or similar. For this the device probably requires
to be opened.
4.2
Fault finding / diagnosis / repair
If the equipment suddenly performs in an unexpected way, which indicates a fault, or it has an obvious defect, this
can not and must not be repaired by the user. Contact the supplier in case of suspicion and elicit the steps to be
taken.
It will then usually be necessary to return the device to the supplier (with or without guarantee). If a return for
checking or repair is to be carried out, ensure that:
•
the supplier has been contacted and it is clarified how and where the equipment should be sent.
•
the device is in fully assembled state and in suitable transport packaging, ideally the original packaging.
•
optional extras such as an AnyBus interface module is included if this is in any way connected to the problem.
•
a fault description in as much detail as possible is attached.
•
if shipping destination is abroad, the necessary customs papers are attached.
4.2.1 Replacing a defect mains fuse
The device is protected one 5x20 mm fuse (for value check fuse body or technical specifications in
1.8.3
) which
is located on the rear of the device, inside a fuse holder (separate or in the AC socket, depends on the model).
To replace the fuse, the device is not required to be opened. Just remove the power cord and unscrew the fuse
holder with a flat screw driver. The replacement fuse must be of same value and type.
4.2.2 Firmware updates
Firmware updates should only be installed if they can eliminate software bugs in the firmware
of your device or contain new features.
The firmware of the control panel (HMI), of the communication unit (KE) and the digital controller (DR), if neces
-
sary, is updated via the rear side USB port. For this the software “EA Power Control” is needed which is included
with the device or available as download from our website, together with the firmware update, or upon request.
