User Manual DC/DC Module PM3K350-1x
Operation
5.1.8
Empty DC Link
If the module is switched on with an empty DC link and a voltage is connected to the
VS side, so firstly it takes place a precharging of the DC link by pre-charging PTC
resistors. If the precharging is successful, the main relais is switched on and the
converter is startet with a reduced current of 1A. Is the DC link charged and the
desired DC link voltage is reached, this limitation is cancelled.
If the precharging of the DC link is not successful, because the PTC resistors
overheat due to large capacities or a load at the DC link, the module switches off with
an error after 10s. The error is “U_ZK too low”.
5.2
Basic Parameterization
The module can only be parameterized by means of the serial interface. It is,
however, more convenient to do this by means of the software belonging to it.
