Failure display
If a failure occurs the red LED on the side of the converter flashes/shines. The number of pulses
after a longer break allows the assignation of the status according to following chart:

Status display changes its status automatically. Fault signals will be deleted when the machine is
restarted (if the cause of defect has been removed).
As soon as the converter is connected to the power supply the Bluetooth interface will be activated
for six minutes. Within this time frame updates can be executed. If there is no access within this time
frame the interface will be deactivated and there is no connection possible as long the converter
stays connected to the power supply. Once the converter gets disconnected from the power supply
for two minutes and is reconnected a new time frame of six minutes will be opened to execute an
update.
In the following, the individual steps for carrying out an update are described in detail:
1)
Connect the converter to the power supply. The status and error report LED on the side of the
case will start flashing or light permanently if there is a machine connected. The converter is
ready and the Bluetooth interface is activated. If the LED stays off please check the power
supply and the wiring. Furthermore pay attention to the additional information below.
2)
Run the "WEKA Service App" on the smartphone (see additional information below) and
select "CHECK FOR UPDATES". Searching can take up to 30 seconds, during this time a list
of all available converters will be created showing the converters by their internal serial
number, e.g. "WEKA FU6 D/C Sn.:00000".
3)
After selecting a listed converter the "WEKA Service App" will compare the current firmware
version to the available versions on the WEKA server and will prompt if an update is available.
If an update is available please confirm by selecting "Yes" to start the process. The converter
will perform all necessary steps fully automatically, meanwhile you can observe the data
transmission on the "WEKA Service App". Once data transmission is completed please wait
until the green LED of the status and error report will start flashing again. The converter has
now booted up with the new firmware and is ready for use.
Measure
- Increase wire cross section (extension cord)
- Check supply cable (cable interrupted)
- Use a generator with more power
- Increase water flow (cooling of motor or converter is
too low; water temperature is too high)
- Check hose connection
Never use waste water for cooling!
- motor stops, motor has been used in the overload
range
- Check motor cable and plug connection for damages
(short circuit)
- Reduce machine load, motor is operated in the
overload range
- Check plug contacts of machine and frequency
converter for dirt and damages
- Update frequency converter (encoding unknown)
- Check motor cable and connectors for damages
(short circuit)
