Automatic firmware update
A firmware update for the replaced DRIVE-CLiQ component may run automatically after
switching on the electronics.
•
The following LEDs will flash slowly to indicate that an automatic firmware update is in
progress: the "RDY" LED on the Control Unit (orange, 0.5 Hz) and an LED on the relevant
DRIVE-CLiQ component (green/red, 0.5 Hz).
Note
Do not shut down the converter
Do not shut down the converter during this process as the firmware update will otherwise
have to be started again.
•
Once the automatic firmware update is complete, the "RDY" LED on the Control Unit will
flash quickly (orange, 2 Hz) along with an LED on the relevant DRIVE-CLiQ component
(green/red, 2 Hz).
•
To complete the automatic firmware update process, a POWER ON is required (switch the
device off and back on again).
