5.12 Safety cut-out in the power section

If there is a fault in the choke or the control electronics, the output voltage is
switched off between terminals D and 1D.

This state is indicated by the „IGBT“ LED, and the fault signal relay drops out.
This safety cut-out remains activated even when the fault has been remedied.
It can only be reset by disconnecting the voltage supply.

h Switch the device off briefly, and then on again

)

In the factory settings, the output level signal corresponds to the I

signal at

the output of the converter. It is thus proportional to the power in the load
(R=constant).

However, setting P or U

instead of the I

2

signals is also possible
