Service and maintenance
4.1
Maintenance / cleaning
The device needs no maintenance. Cleaning may be needed for the internal fans, the frequency of cleanse is
depending on the ambient conditions. The fans serve to cool the components which are heated by the inherent
power loss. Heavily dirt filled fans 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 needs 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 Interface 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 (T16 A, 250 V) which is located on the rear of the device, inside a fuse
holder. 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 when they can eliminate existing bugs in the firm
-
ware in the 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 “EPS 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.
