6 Service & Maintenance
6.1 Maintenance / Cleaning
The unit needs no maintenance. Cleaning may be needed for the internal fans, the frequency of which depends on the
operating environment. 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 unit needs to be opened.
6.2 Troubleshooting / 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 factory for support.
It will usually be necessary to return the unit to the factory. If a return for testing or repair is to be carried out, ensure that:
•
the factory has been contacted and it’s clarified how and where the equipment should be sent, and that a Return Mate
-
rial Auithorization (RMA) has been assigned.
•
the unit 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.
6.2.1 Firmware updates
Firmware updates should only be installed when they can eliminate existing bugs in the firmware in
the system or contain new features.
The firmware of the control panel, the communication unit, and the digital controller, if necessary, may be updated via the
rear USB port. The software EA Power Control is needed which is available as a 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 system. We
recommend to install updates only if
•
an imminent problem with your unit can directly be solved, especially if we suggested to install an update during a sup-
port case
•
a new feature has been added which you definitely want to use. In this case, the full responsibility is transferred to you.
The following also applies in connection with firmware updates:
•
Simple changes in firmwares can have crucial effects on the application the units are use in. We thus recommend to
study the list of changes in the firmware history very thoroughly.
•
Newly implemented features may require an updated documentation (
Operating Guide
and/or
Programming Guide
, as
well as LabView VIs), which is often delivered only later, sometimes significantly later.
