Flashing code as per the error table or warning table
(see chapter on troubleshooting).
4
Flashing, if a warning is active at the same time.

Description of the shutdown process
On devices with 20 kW and 32 kW:
Changing the position of the main switch does not shut down the Top-
Con power supply immediately, instead a shutdown process is initiated.
In particular, the discharge of the internal capacitors takes a certain
amount of time during which the device is still live internally and to
some extent the outputs are still live.
As long as the shutdown process is running:
The three DEVICE LEDs form a running light.
The HMI display indicates “shutting down…”
For this reason it imperative to wait until this process is complete before
undertaking further tasks on the device.
On devices with 10 and 16 kW the shutdown process is so fast that
there is no indication and no delays.
