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
high dissipation of energy. Heavily dirt filled fans can lead to insufficient airflow and therefore the DC input 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 Elektro-Automatik (with or without warranty). 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 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 by a fusible which is inside a fuse holder on the rear of the device. The fuse rating is printed
next to the fuse holder. Replace the fuse only with one of same size and rating.
4.2.2

Firmware update

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 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.
However, be advised not to install updates promptly. Every update includes the risk of an inoperable device or
system. We recommend to install updates only if...
• an imminent problem with your device can directly be solved, especially if we suggested to install an update
during a support case
• a new feature has been added which you definitely want to use. In this case, the full responsibility is transferred
to you.
Following also applies in connection with firmware updates:
• Simple changes in firmwares can have crucial effects on the application the devices ared use in. We thus recom-
mend to study the list of changes in the firmware history very thoroughly.
• Newly implemented features may require an updated documentation (user manual and/or programming guide,
as well as LabView VIs), which is often delivered only later, sometimes significantly later
